Deploying a Red Hat Decision Manager authoring or managed server environment on Red Hat OpenShift Container Platform
Abstract
Preface
As a system engineer, you can deploy a Red Hat Decision Manager authoring or managed environment on Red Hat OpenShift Container Platform to provide a platform for developing or running services and other business assets.
Prerequisites
- At least four gigabytes of memory must be available in the OpenShift cluster/namespace.
- The OpenShift project for the deployment must be created.
-
You must be logged in to the project using the
oc
command. For more information about theoc
command-line tool, see the OpenShift CLI Reference. If you want to use the OpenShift Web console to deploy templates, you must also be logged on using the Web console. - Dynamic persistent volume (PV) provisioning must be enabled. Alternatively, if dynamic PV provisioning is not enabled, a sufficient persistent volume must be available. By default, Decision Central requires one 1Gi PV. You can change the PV size for Decision Central persistent storage in the template parameters.
If you intend to use the Authoring High Availability template, which scales the Decision Central pod:
- The image streams for Red Hat AMQ version 7.1 or later must be available in your OpenShift environment.
- Your OpenShift environment must support persistent volumes with ReadWriteMany mode. For information about access mode support in OpenShift Online volume plug-ins, see Access Modes.
Chapter 1. Overview of Red Hat Decision Manager on Red Hat OpenShift Container Platform
You can deploy Red Hat Decision Manager into a Red Hat OpenShift Container Platform environment.
In this solution, components of Red Hat Decision Manager are deployed as separate OpenShift pods. You can scale each of the pods up and down individually, providing as few or as many containers as necessary for a particular component. You can use standard OpenShift methods to manage the pods and balance the load.
The following key components of Red Hat Decision Manager are available on OpenShift:
Decision Server, also known as Execution Server or KIE Server, is the infrastructure element that runs decision services and other deployable assets (collectively referred to as services) . All logic of the services runs on execution servers.
You can freely scale up a Decision Server pod, providing as many copies as necessary, running on the same host or different hosts. As you scale a pod up or down, all its copies run the same services. OpenShift provides load balancing and a request can be handled by any of the pods.
You can deploy a separate Decision Server pod to run a different group of services. That pod can also be scaled up or down. You can have as many separate replicated Decision Server pods as necessary.
Decision Central is a web-based interactive environment for authoring services. It also provides a management console. You can use Decision Central to develop services and deploy them to Decision Servers.
Decision Central is a centralized application. However, you can configure it for high availability, where multiple pods run and share the same data.
Decision Central includes a Git repository that holds the source for the services that you develop on it. It also includes a built-in Maven repository. Depending on configuration, Decision Central can place the compiled services (KJAR files) into the built-in Maven repository or (if configured) into an external Maven repository.
In the current version, high-availability Decision Central functionality is a technology preview.
You can arrange these and other components into various environment configurations within OpenShift.
The following environment types are typical:
- Authoring or managed environment: An environment architecture that can be used for creating and modifying services using Decision Central and also for running services on Decision Servers. It consists of pods that provide Decision Central for the authoring work and one or more Decision Servers for execution of the services. Each Decision Server is a pod that you can replicate by scaling it up or down as necessary. You can deploy and undeploy services on each Decision Server using Decision Central. For instructions about deploying this environment, see Deploying a Red Hat Decision Manager authoring or managed server environment on Red Hat OpenShift Container Platform.
- Deployment with immutable servers: An alternate environment for running existing services for staging and production purposes. In this environment, when you deploy a Decision Server pod, it builds an image that loads and starts a service or group of services. You cannot stop any service on the pod or add any new service to the pod. If you want to use another version of a service or modify the configuration in any other way, you deploy a new server image and displace the old one. In this system, the Decision Server runs like any other pod on the OpenShift environment; you can use any container-based integration workflows and do not need to use any other tools to manage the pods. For instructions about deploying this environment, see Deploying a Red Hat Decision Manager immutable server environment on Red Hat OpenShift Container Platform.
You can also deploy a trial or evaluation environment. This environment includes Decision Central and a Decision Server. You can set it up quickly and use it to evaluate or demonstrate developing and running assets. However, the environment does not use any persistent storage, and any work you do in the environment is not saved. For instructions about deploying this environment, see Deploying a Red Hat Decision Manager trial environment on Red Hat OpenShift Container Platform.
To deploy a Red Hat Decision Manager environment on OpenShift, you can use the templates that are provided with Red Hat Decision Manager.
Chapter 2. Preparing to deploy Red Hat Decision Manager in your OpenShift environment
Before deploying Red Hat Decision Manager in your OpenShift environment, you need to complete several preparatory tasks. You do not need to repeat these tasks if you want to deploy additional images, for example, for new versions of decision services or for other decision services
2.1. Ensuring the availability of image streams and the image registry
To deploy Red Hat Decision Manager components of Red Hat OpenShift Container Platform, you must ensure that OpenShift can download the correct images from the Red Hat registry. To download the images, OpenShift requires the information about their location (known as image streams). OpenShift also must be configured to authenticate with the Red Hat registry using your service account user name and password.
Some versions of the OpenShift environment include the required image streams. You must check if they are available. If image streams are available in OpenShift by default, you can use them if the OpenShift infrastructure is configured for registry authentication server. The administrator must complete the registry authentication configuration when installing the OpenShift environment.
Otherwise, you can configure registry authentication in your own project and install the image streams in the same project.
Procedure
- Determine whether Red Hat OpenShift Container Platform was configured with the user name and password for Red Hat registry access. For details about the required configuration, see Configuring a Registry Location. If you are using an OpenShift Online subscription, it is configured for Red Hat registry access.
If Red Hat OpenShift Container Platform was configured with the user name and password for Red Hat registry access, run the following commands:
$ oc get imagestreamtag -n openshift | grep rhdm72-decisioncentral-openshift $ oc get imagestreamtag -n openshift | grep rhdm72-kieserver-openshift
If the outputs of both commands are not empty, the required image streams are available in the
openshift
namespace and no further action is required.If the output of one or both of the commands is empty or if OpenShift was not configured with the user name and password for Red Hat registry access, complete the following steps:
-
Ensure you are logged in to OpenShift with the
oc
command and that your project is active. - Complete the steps documented in Registry Service Accounts for Shared Environments. You must log on to Red Hat Customer Portal to access the document and to complete the steps to create a registry service account.
- Select the OpenShift Secret tab and click the link under Download secret to download the YAML secret file.
-
View the downloaded file and note the name that is listed in the
name:
entry. Run the following commands:
oc create -f <file_name>.yaml oc secrets link default <secret_name> --for=pull oc secrets link builder <secret_name> --for=pull
Where
<file_name>
is the name of the downloaded file and <secret_name> is the name that is listed in thename:
entry of the file.-
Download the
rhdm-7.2.0-openshift-templates.zip
product deliverable file from the Software Downloads page and extract therhdm72-image-streams.yaml
file. Complete one of the following actions:
Run the following command:
$ oc create -f rhdm72-image-streams.yaml
Using the OpenShift Web UI, select Add to Project → Import YAML / JSON and then choose the file or paste its contents.
NoteIf you complete these steps, you install the image streams into the namespace of your project. If you install the image streams using these steps, you must set the
IMAGE_STREAM_NAMESPACE
parameter to the name of this project when deploying templates.
-
Ensure you are logged in to OpenShift with the
2.2. Creating the secrets for Decision Server
OpenShift uses objects called Secrets
to hold sensitive information, such as passwords or keystores. See the Secrets chapter in the OpenShift documentation for more information.
You must create an SSL certificate for Decision Server and provide it to your OpenShift environment as a secret.
Procedure
Generate an SSL keystore with a private and public key for SSL encryption for Decision Server. In a production environment, generate a valid signed certificate that matches the expected URL of the Decision Server. Save the keystore in a file named
keystore.jks
. Record the name of the certificate and the password of the keystore file.See Generate a SSL Encryption Key and Certificate for more information on how to create a keystore with self-signed or purchased SSL certificates.
Use the
oc
command to generate a secret namedkieserver-app-secret
from the new keystore file:$ oc create secret generic kieserver-app-secret --from-file=keystore.jks
2.3. Creating the secrets for Decision Central
If you are planning to deploy Decision Central in your OpenShift environment, you must create an SSL certificate for Decision Central and provide it to your OpenShift environment as a secret. Do not use the same certificate and keystore for Decision Central and for Decision Server.
Procedure
Generate an SSL keystore with a private and public key for SSL encryption for Decision Central. In a production environment, generate a valid signed certificate that matches the expected URL of the Decision Central. Save the keystore in a file named
keystore.jks
. Record the name of the certificate and the password of the keystore file.See Generate a SSL Encryption Key and Certificate for more information on how to create a keystore with self-signed or purchased SSL certificates.
Use the
oc
command to generate a secret nameddecisioncentral-app-secret
from the new keystore file:$ oc create secret generic decisioncentral-app-secret --from-file=keystore.jks
2.4. Changing GlusterFS configuration
Check whether your OpenShift environment uses GlusterFS to provide permanent storage volumes. If it uses GlusterFS, to ensure optimal performance, tune your GlusterFS storage by changing the storage class configuration.
Procedure
To check whether your environment uses GlusterFS, run the following command:
oc get storageclass
In the results, check whether the
(default)
marker is on the storage class that listsglusterfs
. For example, in the following output the default storage class isgluster-container
, which does listglusterfs
:NAME PROVISIONER AGE gluster-block gluster.org/glusterblock 8d gluster-container (default) kubernetes.io/glusterfs 8d
If the result has a default storage class that does not list
glusterfs
or if the result is empty, you do not need to make any changes. In this case, skip the rest of this procedure.To save the configuration of the default storage class into a YAML file, run the following command:
oc get storageclass <class-name> -o yaml >storage_config.yaml
Where
class-name
is the name of the default storage class. For example:oc get storageclass gluster-container -o yaml >storage_config.yaml
Edit the
storage_config.yaml
file:Remove the lines with the following keys:
-
creationTimestamp
-
resourceVersion
-
selfLink
-
uid
-
On the line with the
volumeoptions
key, add the following two options:features.cache-invalidation on, performance.nl-cache on
. For example:volumeoptions: client.ssl off, server.ssl off, features.cache-invalidation on, performance.nl-cache on
To remove the existing default storage class, run the following command:
oc delete storageclass <class-name>
Where
class-name
is the name of the default storage class. For example:oc delete storageclass gluster-container
To re-create the storage class using the new configuration, run the following command:
oc create -f storage_config.yaml
Chapter 3. Authoring or managed server environment
You can deploy an environment for creating and modifying services using Decision Central and for running them in Decision Servers managed by Decision Central. This environment consists of Decision Central and one or more Decision Servers.
You can use Decision Central both to develop services and to deploy them to one or several Decision Servers. For example, you can deploy test versions of services to one Decision Server and production versions to another Decision Server.
To avoid accidentally deploying wrong versions to a production Decision Server, you can create separate environments to author services (authoring environment) and to manage deployment of production services (managed server environment). You can use a shared external Maven repository between these environments, so that services developed in the authoring environment are available in the managed server environment. However, the procedures to deploy these environments are the same.
Depending on your needs, you can deploy either a single or high-availability Decision Central. A single Decision Central pod is not replicated; only a single copy of Decision Central is used. In an HA Decision Central deployment, you can scale Decision Central.
An HA Decision Central provides maximum reliability and responsiveness for authoring services, but has higher memory and storage requirements and also requires support for persistent volumes with ReadWriteMany mode.
In the current version, the high-availability functionality is a technology preview.
You can scale Decision Server pods as necessary in any version of the authoring or managed server environment.
To deploy an authoring or managed server environment, first deploy the single or high-availability Decision Central and a single Decision Server using the authoring template.
To add additional Decision Servers, you can deploy the Decision Server template in the same project.
3.1. Deploying single Decision Central and one Decision Server in an authoring or managed server environment
To deploy single Decision Central and one Decision Server in an authoring or managed server environment, use the rhdm72-authoring.yaml
template file. You can extract this file from the rhdm-7.2.0-openshift-templates.zip
product deliverable file. You can download the file from the Software Downloads page.
Procedure
Use one of the following methods to deploy the template:
-
In the OpenShift Web UI, select Add to Project → Import YAML / JSON and then select or paste the
rhdm72-authoring.yaml
file. In the Add Template window, ensure Process the template is selected and click Continue. To use the OpenShift command line console, prepare the following command line:
oc new-app -f <template-path>/rhdm72-authoring.yaml -p DECISION_CENTRAL_HTTPS_SECRET=decisioncentral-app-secret -p KIE_SERVER_HTTPS_SECRET=kieserver-app-secret
In this command line:
-
Replace

parameters of the template. These parameters correspond to the settings of the LdatExtended Login module of Red Hat JBoss EAP. For instructions about using these settings, see LdapExtended Login Module.If the LDAP server does not define all the roles required for your deployment, you can map LDAP groups to Red Hat Decision Manager roles. To enable LDAP role mapping, set the following parameters:
-
RoleMapping rolesProperties file path (
AUTH_ROLE_MAPPER_ROLES_PROPERTIES
): The fully qualified pathname of a file that defines role mapping, for example,/opt/eap/standalone/configuration/rolemapping/rolemapping.properties

3.3. Providing the Git hooks directory
If you configure the GIT_HOOKS_DIR
parameter, you must provide a directory of Git hooks and must mount this directory on the Decision Central deployment.
The typical use of Git hooks is interaction with an upstream repository. To enable Git hooks to push commits into an upstream repository, you must also provide a secret key that corresponds to a public key configured on the upstream repository.
Procedure
If interaction with an upstream repository using SSH authentication is required, complete the following steps to prepare and mount a secret with the necessary files:
-
Prepare the
id_rsa
file with a private key that matches a public key stored in the repository. -
Prepare the
known_hosts
file with the correct name, address, and public key for the repository. Create a secret with the two files using the
oc
command, for example:oc create secret git-hooks-secret --from-file=id_rsa=id_rsa --from-file=known_hosts=known_hosts
Mount the secret in the SSH key path of the Decision Central deployment, for example:
oc set volume dc/<myapp>-rhdmcentr --add --type secret --secret-name git-hooks-secret --mount-path=/home/jboss/.ssh --name=ssh-key
Where
<myapp>
is the application name that was set when configuring the template.
-
Prepare the
Create the Git hooks directory. For instructions, see the Git hooks reference documentation.
For example, a simple git hooks directory can provide a post-commit hook that pushes the changes upstream. If the project was imported into Decision Central from a repository, this repository remains configured as the upstream repository. Create a file named
post-commit
with permission values755
and the following content:git push
Supply the Git hooks directory to the Decision Central deployment. You can use a configuration map or a persistent volume.
If the Git hooks consist of one or several fixed script files, use a configuration map. Complete the following steps:
- Change into the Git hooks directory that you have created.
Create an OpenShift configuration map from the files in the directory. Run the following command:
oc create configmap git-hooks --from-file=<file_1>=<file_1> --from-file=<file_2>=<file_2> ...
Where
file_1
,file_2
and so on are git hook script files. For example:oc create configmap git-hooks --from-file=post-commit=post-commit
Mount the configuration map on the Decision Central deployment in the path that you have configured:
oc set volume dc/<myapp>-rhdmcentr --add --type configmap --configmap-name git-hooks --mount-path=<git_hooks_dir> --name=git-hooks
Where
<myapp>
is the application name that was set when configuring the template and<git_hooks_dir>
is the value ofGIT_HOOKS_DIR
that was set when configuring the template.
-
If the Git hooks consist of long files or depend on binaries, such as executable or KJAR files, use a persistence volume. You must create a persistent volume, create a persistent volume claim and associate the volume with the claim, transfer files to the volume, and mount the volume in the
myapp-rhdmcentr
deployment configuration (where myapp is the application name). For instructions about creating and mounting persistence volumes, see Using persistent volumes. For instructions about copying files onto a persistent volume, see Transferring files in and out of containers.
Wait a few minutes, then review the list and status of pods in yor project. Because Decision Central does not start until you provide the Git hooks directory, the Decision Server might not start at all. To see if it has started, check the output of the following command:
oc get pods
If a working Decision Server pod is not present, start it:
oc rollout latest dc/<myapp>-kieserver
Where
<myapp>
is the application name that was set when configuring the template.
3.4. Deploying an additional Decision Server
As a part of a managed server infrastructure, you can deploy an additional Decision Server on the OpenShift infrastructure. You can then use Decision Central to deploy, undeploy, and manage services on this Decision Server.
To deploy an additional Decision Server, use the rhdm72-kieserver.yaml
template file. You can download the file from the Software Downloads page.
Procedure
Use one of the following methods to deploy the template:
-
In the OpenShift Web UI, select Add to Project → Import YAML / JSON and then select or paste the
rhdm72-kieserver.yaml
file. In the Add Template window, ensure Process the template is selected and click Continue. To use the OpenShift command line console, prepare the following command line:
oc new-app -f <template-path>/rhdm72-kieserver.yaml -p KIE_SERVER_HTTPS_SECRET=kieserver-app-secret
In this command line:
-
Replace
<template-path>
with the path to the downloaded template file. -
Use as many
-p PARAMETER=value
pairs as needed to set the required parameters. You can view the template file to see descriptions for all parameters.
-
Replace

Service | Port | Name | Description |
---|---|---|---|
| 8080 | http | All the Decision Central web server’s ports. |
8443 | https | ||
8001 | git-ssh | ||
| 8080 | http | All the KIE server web server’s ports. |
8443 | https |
4.1.2.2. Routes
A route is a way to expose a service by giving it an externally-reachable hostname such as www.example.com
. A defined route and the endpoints identified by its service can be consumed by a router to provide named connectivity from external clients to your applications. Each route consists of a route name, service selector, and (optionally) security configuration. Refer to the Openshift documentation for more information.
Service | Security | Hostname |

4.1.2.3. Deployment Configurations
A deployment in OpenShift is a replication controller based on a user defined template called a deployment configuration. Deployments are created manually or in response to triggered events. Refer to the Openshift documentation for more information.
4.1.2.3.1. Triggers
A trigger drives the creation of new deployments in response to events, both inside and outside OpenShift. Refer to the Openshift documentation for more information.

4.2.2.2. Routes
A route is a way to expose a service by giving it an externally-reachable hostname such as www.example.com
. A defined route and the endpoints identified by its service can be consumed by a router to provide named connectivity from external clients to your applications. Each route consists of a route name, service selector, and (optionally) security configuration. Refer to the Openshift documentation for more information.

4.2.2.3. Deployment Configurations
A deployment in OpenShift is a replication controller based on a user defined template called a deployment configuration. Deployments are created manually or in response to triggered events. Refer to the Openshift documentation for more information.
4.2.2.3.1. Triggers
A trigger drives the creation of new deployments in response to events, both inside and outside OpenShift. Refer to the Openshift documentation for more information.

4.2.2.3.2. Replicas
A replication controller ensures that a specified number of pod "replicas" are running at any one time. If there are too many, the replication controller kills some pods. If there are too few, it starts more. Refer to the container-engine documentation for more information.

4.2.2.4.2. Secrets
This template requires the following secrets to be installed for the application to run.
decisioncentral-app-secret kieserver-app-secret
4.2.2.4.3. Clustering
Clustering in OpenShift EAP is achieved through one of two discovery mechanisms: Kubernetes or DNS. This is done by configuring the JGroups protocol stack in standalone-openshift.xml with either the <openshift.KUBE_PING/>
or <openshift.DNS_PING/>
elements. The templates are configured to use DNS_PING
, however `KUBE_PING`is the default used by the image.
The discovery mechanism used is specified by the JGROUPS_PING_PROTOCOL
environment variable which can be set to either openshift.DNS_PING
or openshift.KUBE_PING
. openshift.KUBE_PING
is the default used by the image if no value is specified for JGROUPS_PING_PROTOCOL
.
For DNS_PING to work, the following steps must be taken:
-
The
OPENSHIFT_DNS_PING_SERVICE_NAME
environment variable must be set to the name of the ping service for the cluster (see table above). If not set, the server will act as if it is a single-node cluster (a "cluster of one"). -
The
OPENSHIFT_DNS_PING_SERVICE_PORT
environment variables should be set to the port number on which the ping service is exposed (see table above). TheDNS_PING
protocol will attempt to discern the port from the SRV records, if it can, otherwise it will default to 8888. A ping service which exposes the ping port must be defined. This service should be "headless" (ClusterIP=None) and must have the following:
- The port must be named for port discovery to work.
-
It must be annotated with
service.alpha.kubernetes.io/tolerate-unready-endpoints
set to"true"
. Omitting this annotation will result in each node forming their own "cluster of one" during startup, then merging their cluster into the other nodes' clusters after startup (as the other nodes are not detected until after they have started).
Example ping service for use with DNS_PING
kind: Service apiVersion: v1 spec: clusterIP: None ports: - name: ping port: 8888 selector: deploymentConfig: eap-app metadata: name: eap-app-ping annotations: service.alpha.kubernetes.io/tolerate-unready-endpoints: "true" description: "The JGroups ping port for clustering."
For KUBE_PING
to work, the following steps must be taken:
-
The
OPENSHIFT_KUBE_PING_NAMESPACE
environment variable must be set (see table above). If not set, the server will act as if it is a single-node cluster (a "cluster of one"). -
The
OPENSHIFT_KUBE_PING_LABELS
environment variables should be set (see table above). If not set, pods outside of your application (albeit in your namespace) will try to join. - Authorization must be granted to the service account the pod is running under to be allowed to access Kubernetes' REST api. This is done on the command line.
Example 4.1. Policy commands
Using the default service account in the myproject namespace:
oc policy add-role-to-user view system:serviceaccount:myproject:default -n myproject
Using the eap-service-account in the myproject namespace:
oc policy add-role-to-user view system:serviceaccount:myproject:eap-service-account -n myproject
4.3. rhdm72-kieserver.yaml template

4.3.2. Objects
The CLI supports various object types. A list of these object types as well as their abbreviations can be found in the Openshift documentation.
4.3.2.1. Services
A service is an abstraction which defines a logical set of pods and a policy by which to access them. Refer to the container-engine documentation for more information.
Service | Port | Name | Description |
---|---|---|---|
| 8080 | http | All the KIE server web server’s ports. |
8443 | https | ||
| 8888 | ping | The JGroups ping port for clustering. |
4.3.2.2. Routes
A route is a way to expose a service by giving it an externally-reachable hostname such as www.example.com
. A defined route and the endpoints identified by its service can be consumed by a router to provide named connectivity from external clients to your applications. Each route consists of a route name, service selector, and (optionally) security configuration. Refer to the Openshift documentation for more information.
Service | Security | Hostname |
---|---|---|
| none |
|
| TLS passthrough |
|
4.3.2.3. Deployment Configurations
A deployment in OpenShift is a replication controller based on a user defined template called a deployment configuration. Deployments are created manually or in response to triggered events. Refer to the Openshift documentation for more information.
4.3.2.3.1. Triggers
A trigger drives the creation of new deployments in response to events, both inside and outside OpenShift. Refer to the Openshift documentation for more information.
Deployment | Triggers |
---|---|
| ImageChange |
4.3.2.3.2. Replicas
A replication controller ensures that a specified number of pod "replicas" are running at any one time. If there are too many, the replication controller kills some pods. If there are too few, it starts more. Refer to the container-engine documentation for more information.
Deployment | Replicas |
---|---|
| 1 |
4.3.2.3.3. Pod Template
4.3.2.3.3.1. Service Accounts
Service accounts are API objects that exist within each project. They can be created or deleted like any other API object. Refer to the Openshift documentation for more information.

4.4. OpenShift usage quick reference
To deploy, monitor, manage, and undeploy Red Hat Decision Manager templates on Red Hat OpenShift Container Platform, you can use the OpenShift Web console or the oc
command.
For instructions about using the Web console, see Create and build an image using the Web console.
For detailed instructions about using the oc
command, see CLI Reference. The following commands are likely to be required:
To create a project, use the following command:
$ oc new-project <project-name>
For more information, see Creating a project using the CLI.
To deploy a template (create an application from a template), use the following command:
$ oc new-app -f <template-name> -p <parameter>=<value> -p <parameter>=<value> ...
For more information, see Creating an application using the CLI.
To view a list of the active pods in the project, use the following command:
$ oc get pods
To view the current status of a pod, including information whether or not the pod deployment has completed and it is now in a running state, use the following command:
$ oc describe pod <pod-name>
You can also use the
oc describe
command to view the current status of other objects. For more information, see Application modification operations.To view the logs for a pod, use the following command:
$ oc logs <pod-name>
To view deployment logs, look up a
DeploymentConfig
name in the template reference and run the following command:$ oc logs -f dc/<deployment-config-name>
For more information, see Viewing deployment logs.
To view build logs, look up a
BuildConfig
name in the template reference and run the command:$ oc logs -f bc/<build-config-name>
For more information, see Accessing build logs.
To scale a pod in the application, look up a
DeploymentConfig
name in the template reference and run the command:$ oc scale dc/<deployment-config-name> --replicas=<number>
For more information, see Manual scaling.
To undeploy the application, you can delete the project by using the command:
$ oc delete project <project-name>
Alternatively, you can use the
oc delete
command to remove any part of the application, such as a pod or replication controller. For details, see Application modification operations.
