CLI tools
Learning how to use the command-line tools for OpenShift Container Platform
Abstract
Chapter 1. OpenShift Container Platform CLI tools overview Copier lienLien copié sur presse-papiers!
A user performs a range of operations while working on OpenShift Container Platform such as the following:
- Managing clusters
- Building, deploying, and managing applications
- Managing deployment processes
- Developing Operators
- Creating and maintaining Operator catalogs
OpenShift Container Platform offers a set of command-line interface (CLI) tools that simplify these tasks by enabling users to perform various administration and development operations from the terminal. These tools expose simple commands to manage the applications, as well as interact with each component of the system.
1.1. List of CLI tools Copier lienLien copié sur presse-papiers!
The following set of CLI tools are available in OpenShift Container Platform:
-
OpenShift CLI (
oc
): This is the most commonly used CLI tool by OpenShift Container Platform users. It helps both cluster administrators and developers to perform end-to-end operations across OpenShift Container Platform using the terminal. Unlike the web console, it allows the user to work directly with the project source code using command scripts. -
Knative CLI (kn): The Knative (
kn
) CLI tool provides simple and intuitive terminal commands that can be used to interact with OpenShift Serverless components, such as Knative Serving and Eventing. -
Pipelines CLI (tkn): OpenShift Pipelines is a continuous integration and continuous delivery (CI/CD) solution in OpenShift Container Platform, which internally uses Tekton. The
tkn
CLI tool provides simple and intuitive commands to interact with OpenShift Pipelines using the terminal. -
opm CLI: The
opm
CLI tool helps the Operator developers and cluster administrators to create and maintain the catalogs of Operators from the terminal. - Operator SDK: The Operator SDK, a component of the Operator Framework, provides a CLI tool that Operator developers can use to build, test, and deploy an Operator from the terminal. It simplifies the process of building Kubernetes-native applications, which can require deep, application-specific operational knowledge.

2.3. Usage of oc and kubectl commands Copier lienLien copié sur presse-papiers!
The Kubernetes command-line interface (CLI), kubectl
, can be used to run commands against a Kubernetes cluster. Because OpenShift Container Platform is a certified Kubernetes distribution, you can use the supported kubectl
binaries that ship with OpenShift Container Platform , or you can gain extended functionality by using the oc
binary.
2.3.1. The oc binary Copier lienLien copié sur presse-papiers!
The oc
binary offers the same capabilities as the kubectl
binary, but it extends to natively support additional OpenShift Container Platform features, including:
Full support for OpenShift Container Platform resources
Resources such as
DeploymentConfig
,BuildConfig
,Route
,ImageStream
, andImageStreamTag
objects are specific to OpenShift Container Platform distributions, and build upon standard Kubernetes primitives.Authentication
The
oc
binary offers a built-inlogin
command for authentication and lets you work with projects, which map Kubernetes namespaces to authenticated users. Read Understanding authentication for more information.Additional commands
The additional command
oc new-app
, for example, makes it easier to get new applications started using existing source code or pre-built images. Similarly, the additional commandoc new-project
makes it easier to start a project that you can switch to as your default.
If you installed an earlier version of the oc
binary, you cannot use it to complete all of the commands in OpenShift Container Platform 4.16 . If you want the latest features, you must download and install the latest version of the oc
binary corresponding to your OpenShift Container Platform server version.
Non-security API changes will involve, at minimum, two minor releases (4.1 to 4.2 to 4.3, for example) to allow older oc
binaries to update. Using new capabilities might require newer oc
binaries. A 4.3 server might have additional capabilities that a 4.2 oc
binary cannot use and a 4.3 oc
binary might have additional capabilities that are unsupported by a 4.2 server.

2.3.2. The kubectl binary Copier lienLien copié sur presse-papiers!
The kubectl
binary is provided as a means to support existing workflows and scripts for new OpenShift Container Platform users coming from a standard Kubernetes environment, or for those who prefer to use the kubectl
CLI. Existing users of kubectl
can continue to use the binary to interact with Kubernetes primitives, with no changes required to the OpenShift Container Platform cluster.
You can install the supported kubectl
binary by following the steps to Install the OpenShift CLI. The kubectl
binary is included in the archive if you download the binary, or is installed when you install the CLI by using an RPM.
For more information, see the kubectl documentation.
2.4. Managing CLI profiles Copier lienLien copié sur presse-papiers!
A CLI configuration file allows you to configure different profiles, or contexts, for use with the CLI tools overview. A context consists of user authentication an OpenShift Container Platform server information associated with a nickname.
2.4.1. About switches between CLI profiles Copier lienLien copié sur presse-papiers!
Contexts allow you to easily switch between multiple users across multiple OpenShift Container Platform servers, or clusters, when using CLI operations. Nicknames make managing CLI configurations easier by providing short-hand references to contexts, user credentials, and cluster details. After a user logs in with the oc
CLI for the first time, OpenShift Container Platform creates a ~/.kube/config
file if one does not already exist. As more authentication and connection details are provided to the CLI, either automatically during an oc login
operation or by manually configuring CLI profiles, the updated information is stored in the configuration file:
CLI config file
- 1
- The
clusters
section defines connection details for OpenShift Container Platform clusters, including the address for their master server. In this example, one cluster is nicknamedopenshift1.example.com:8443
and another is nicknamedopenshift2.example.com:8443
. - 2
- This
contexts
section defines two contexts: one nicknamedalice-project/openshift1.example.com:8443/alice
, using thealice-project
project,openshift1.example.com:8443
cluster, andalice
user, and another nicknamedjoe-project/openshift1.example.com:8443/alice
, using thejoe-project
project,openshift1.example.com:8443
cluster andalice
user. - 3
- The
current-context
parameter shows that thejoe-project/openshift1.example.com:8443/alice
context is currently in use, allowing thealice
user to work in thejoe-project
project on theopenshift1.example.com:8443
cluster. - 4
- The
users
section defines user credentials. In this example, the user nicknamealice/openshift1.example.com:8443
uses an access token.
The CLI can support multiple configuration files which are loaded at runtime and merged together along with any override options specified from the command line. After you are logged in, you can use the oc status
or oc project
command to verify your current working environment:
Verify the current working environment
oc status
$ oc status
Example output
List the current project
oc project
$ oc project
Example output
Using project "joe-project" from context named "joe-project/openshift1.example.com:8443/alice" on server "https://openshift1.example.com:8443".
Using project "joe-project" from context named "joe-project/openshift1.example.com:8443/alice" on server "https://openshift1.example.com:8443".
You can run the oc login
command again and supply the required information during the interactive process, to log in using any other combination of user credentials and cluster details. A context is constructed based on the supplied information if one does not already exist. If you are already logged in and want to switch to another project the current user already has access to, use the oc project
command and enter the name of the project:
oc project alice-project
$ oc project alice-project
Example output
Now using project "alice-project" on server "https://openshift1.example.com:8443".
Now using project "alice-project" on server "https://openshift1.example.com:8443".
At any time, you can use the oc config view
command to view your current CLI configuration, as seen in the output. Additional CLI configuration commands are also available for more advanced usage.
If you have access to administrator credentials but are no longer logged in as the default system user system:admin
, you can log back in as this user at any time as long as the credentials are still present in your CLI config file. The following command logs in and switches to the default project:
oc login -u system:admin -n default
$ oc login -u system:admin -n default
2.4.2. Manual configuration of CLI profiles Copier lienLien copié sur presse-papiers!
This section covers more advanced usage of CLI configurations. In most situations, you can use the oc login
and oc project
commands to log in and switch between contexts and projects.
If you want to manually configure your CLI config files, you can use the oc config
command instead of directly modifying the files. The oc config
command includes a number of helpful sub-commands for this purpose:
Subcommand | Usage |
---|---|
| Sets a cluster entry in the CLI config file. If the referenced cluster nickname already exists, the specified information is merged in. oc config set-cluster <cluster_nickname> [--server=<master_ip_or_fqdn>]
|
| Sets a context entry in the CLI config file. If the referenced context nickname already exists, the specified information is merged in. oc config set-context <context_nickname> [--cluster=<cluster_nickname>]
|
| Sets the current context using the specified context nickname. oc config use-context <context_nickname>
|
| Sets an individual value in the CLI config file. oc config set <property_name> <property_value>
The |

- Update the current context to have users log in to the desired namespace:
oc config set-context `oc config current-context` --namespace=<project_name>
$ oc config set-context `oc config current-context` --namespace=<project_name>
- Examine the current context, to confirm that the changes are implemented:
oc whoami -c
$ oc whoami -c
All subsequent CLI operations uses the new context, unless otherwise specified by overriding CLI options or until the context is switched.
2.4.3. Load and merge rules Copier lienLien copié sur presse-papiers!
You can follow these rules, when issuing CLI operations for the loading and merging order for the CLI configuration:
CLI config files are retrieved from your workstation, using the following hierarchy and merge rules:
-
If the
--config
option is set, then only that file is loaded. The flag is set once and no merging takes place. -
If the
$KUBECONFIG
environment variable is set, then it is used. The variable can be a list of paths, and if so the paths are merged together. When a value is modified, it is modified in the file that defines the stanza. When a value is created, it is created in the first file that exists. If no files in the chain exist, then it creates the last file in the list. -
Otherwise, the
~/.kube/config
file is used and no merging takes place.
-
If the
The context to use is determined based on the first match in the following flow:
-
The value of the
--context
option. -
The
current-context
value from the CLI config file. - An empty value is allowed at this stage.
-
The value of the
The user and cluster to use is determined. At this point, you may or may not have a context; they are built based on the first match in the following flow, which is run once for the user and once for the cluster:
-
The value of the
--user
for user name and--cluster
option for cluster name. -
If the
--context
option is present, then use the context’s value. - An empty value is allowed at this stage.
-
The value of the
The actual cluster information to use is determined. At this point, you may or may not have cluster information. Each piece of the cluster information is built based on the first match in the following flow:
The values of any of the following command-line options:
-
--server
, -
--api-version
-
--certificate-authority
-
--insecure-skip-tls-verify
-
- If cluster information and a value for the attribute is present, then use it.
- If you do not have a server location, then there is an error.
The actual user information to use is determined. Users are built using the same rules as clusters, except that you can only have one authentication technique per user; conflicting techniques cause the operation to fail. Command-line options take precedence over config file values. Valid command-line options are:
-
--auth-path
-
--client-certificate
-
--client-key
-
--token
-
- For any information that is still missing, default values are used and prompts are given for additional information.
2.5. Extending the OpenShift CLI with plugins Copier lienLien copié sur presse-papiers!
You can write and install plugins to build on the default oc
commands, allowing you to perform new and more complex tasks with the OpenShift Container Platform CLI.
2.5.1. Writing CLI plugins Copier lienLien copié sur presse-papiers!
You can write a plugin for the OpenShift Container Platform CLI in any programming language or script that allows you to write command-line commands. Note that you can not use a plugin to overwrite an existing oc
command.
Procedure
This procedure creates a simple Bash plugin that prints a message to the terminal when the oc foo
command is issued.
Create a file called
oc-foo
.When naming your plugin file, keep the following in mind:
-
The file must begin with
oc-
orkubectl-
to be recognized as a plugin. -
The file name determines the command that invokes the plugin. For example, a plugin with the file name
oc-foo-bar
can be invoked by a command ofoc foo bar
. You can also use underscores if you want the command to contain dashes. For example, a plugin with the file nameoc-foo_bar
can be invoked by a command ofoc foo-bar
.
-
The file must begin with
Add the following contents to the file.
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
After you install this plugin for the OpenShift Container Platform CLI, it can be invoked using the oc foo
command.
2.5.2. Installing and using CLI plugins Copier lienLien copié sur presse-papiers!
After you write a custom plugin for the OpenShift Container Platform CLI, you must install the plugin before use.
Prerequisites
-
You must have the
oc
CLI tool installed. -
You must have a CLI plugin file that begins with
oc-
orkubectl-
.
Procedure
If necessary, update the plugin file to be executable.
chmod +x <plugin_file>
$ chmod +x <plugin_file>
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Place the file anywhere in your
PATH
, such as/usr/local/bin/
.sudo mv <plugin_file> /usr/local/bin/.
$ sudo mv <plugin_file> /usr/local/bin/.
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Run
oc plugin list
to make sure that the plugin is listed.oc plugin list
$ oc plugin list
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Example output
The following compatible plugins are available: /usr/local/bin/<plugin_file>
The following compatible plugins are available: /usr/local/bin/<plugin_file>
Copy to Clipboard Copied! Toggle word wrap Toggle overflow If your plugin is not listed here, verify that the file begins with
oc-
orkubectl-
, is executable, and is on yourPATH
.Invoke the new command or option introduced by the plugin.
For example, if you built and installed the
kubectl-ns
plugin from the Sample plugin repository, you can use the following command to view the current namespace.oc ns
$ oc ns
Copy to Clipboard Copied! Toggle word wrap Toggle overflow Note that the command to invoke the plugin depends on the plugin file name. For example, a plugin with the file name of
oc-foo-bar
is invoked by theoc foo bar
command.

7.1. Installing the opm CLI Copier lienLien copié sur presse-papiers!
7.1.1. About the opm CLI Copier lienLien copié sur presse-papiers!
The opm
CLI tool is provided by the Operator Framework for use with the Operator bundle format. This tool allows you to create and maintain catalogs of Operators from a list of Operator bundles that are similar to software repositories. The result is a container image which can be stored in a container registry and then installed on a cluster.
A catalog contains a database of pointers to Operator manifest content that can be queried through an included API that is served when the container image is run. On OpenShift Container Platform, Operator Lifecycle Manager (OLM) can reference the image in a catalog source, defined by a CatalogSource
object, which polls the image at regular intervals to enable frequent updates to installed Operators on the cluster.

Chapter 8. Operator SDK Copier lienLien copié sur presse-papiers!
8.1. Installing the Operator SDK CLI Copier lienLien copié sur presse-papiers!
The Operator SDK provides a command-line interface (CLI) tool that Operator developers can use to build, test, and deploy an Operator. You can install the Operator SDK CLI on your workstation so that you are prepared to start authoring your own Operators.
The Red Hat-supported version of the Operator SDK CLI tool, including the related scaffolding and testing tools for Operator projects, is deprecated and is planned to be removed in a future release of OpenShift Container Platform. Red Hat will provide bug fixes and support for this feature during the current release lifecycle, but this feature will no longer receive enhancements and will be removed from future OpenShift Container Platform releases.
The Red Hat-supported version of the Operator SDK is not recommended for creating new Operator projects. Operator authors with existing Operator projects can use the version of the Operator SDK CLI tool released with OpenShift Container Platform 4.16 to maintain their projects and create Operator releases targeting newer versions of OpenShift Container Platform.
The following related base images for Operator projects are not deprecated. The runtime functionality and configuration APIs for these base images are still supported for bug fixes and for addressing CVEs.
- The base image for Ansible-based Operator projects
- The base image for Helm-based Operator projects
For the most recent list of major functionality that has been deprecated or removed within OpenShift Container Platform, refer to the Deprecated and removed features section of the OpenShift Container Platform release notes.
For information about the unsupported, community-maintained, version of the Operator SDK, see Operator SDK (Operator Framework).
Operator authors with cluster administrator access to a Kubernetes-based cluster, such as OpenShift Container Platform, can use the Operator SDK CLI to develop their own Operators based on Go, Ansible, Java, or Helm. Kubebuilder is embedded into the Operator SDK as the scaffolding solution for Go-based Operators, which means existing Kubebuilder projects can be used as is with the Operator SDK and continue to work. See Developing Operators for full documentation on the Operator SDK.
