Chapter 2. Setting up the Fuse Console on OpenShift 4.x

1. Log in to the OpenShift console in your web browser as a user with cluster admin access.
2. Click Operators and then click OperatorHub.
3. In the search field window, type Fuse Console to filter the list of operators.
4. Click Fuse Console Operator.

5. In the Fuse Console Operator install window, click Install.

   The Create Operator Subscription form opens.

   • For Update Channel, select 7.11.x.

   • For Installation Mode, accept the default (a specific namespace on the cluster).

     Note that after you install the operator, when you deploy the Fuse Console, you can choose to monitor applications in all namespaces on the cluster or to monitor applications only in the namespace in which the Fuse Console operator is installed.

   • For Installed Namespace, select the namespace in which you want to install the Fuse Console Operator.

   • For the Update Approval, you can select Automatic or Manual to configure how OpenShift handles updates to the Fuse Console Operator.

     • If you select Automatic updates, when a new version of the Fuse Console Operator is available, the OpenShift Operator Lifecycle Manager (OLM) automatically upgrades the running instance of the Fuse Console without human intervention.
     • If you select Manual updates, when a newer version of an Operator is available, the OLM creates an update request. As a cluster administrator, you must then manually approve that update request to have the Fuse Console Operator updated to the new version.

6. Click Install.

   OpenShift installs the Fuse Console Operator in the current namespace.

7. To verify the installation, click Operators and then click Installed Operators. You can see the Fuse Console in the list of operators.

8. To deploy the Fuse Console by using the OpenShift web console:

   1. In the list of Installed Operators, under the Name column, click Fuse Console.

   2. On the Operator Details page under Provided APIs, click Create Instance.

      Accept the configuration default values or optionally edit them.

      For Replicas, if you want to increase the Fuse Console performance (for example, in a high availability environment), you can increase the number of pods allocated to the Fuse Console.

      For Rbac (role-based access control), only specify a value in the config Map field if you want to customize the default RBAC behavior and if the ConfigMap file already exists in the namespace in which you installed the Fuse Console Operator. For more information about RBAC, see Role-based access control for the Fuse Console on OpenShift 4.x.

      For Nginx, see Performance tuning for Fuse Console Operator installation.

   3. Click Create.

      The Fuse Console Operator Details page opens and shows the status of the deployment.

9. To open the Fuse Console:

   1. For a namespace deployment: In the OpenShift web console, open the project in which you installed the Fuse Console operator, and then select Overview. In the Project Overview page, scroll down to the Launcher section and click the Fuse Console link.

      For a cluster deployment, in the OpenShift web console’s title bar, click the grid icon ( ). In the popup menu, under Red Hat applications, click the Fuse Console URL link.

   2. Log into the Fuse Console.

      An Authorize Access page opens in the browser listing the required permissions.

   3. Click Allow selected permissions.

      The Fuse Console opens in the browser and shows the Fuse application pods that you have authorization to access.

10. Click Connect for the application that you want to view.

    A new browser window opens showing the application in the Fuse Console.

Procedure

1. Verify that the Fuse Console image stream is installed by using the following command to retrieve a list of all templates:

   oc get template -n openshift

2. Optionally, if you want to update the already installed image stream with new release tags, use the following command to import the Fuse Console image to the openshift namespace:

   oc import-image fuse7/fuse-console-rhel8:1.10 --from=registry.redhat.io/fuse7/fuse-console-rhel8:1.10 --confirm -n openshift

3. Obtain the Fuse Console APP_NAME value by running the following command:

   oc process --parameters -f TEMPLATE-FILENAME

   where TEMPLATE-FILENAME is one of the following templates:

   • Cluster template:

     `https://github.com/jboss-fuse/application-templates/blob/application-templates-2.1.0.fuse-sb2-7_11_1-00016-redhat-00002//fuse-console-cluster-os4.json`

   • Cluster template with configurable RBAC:

     `https://github.com/jboss-fuse/application-templates/blob/application-templates-2.1.0.fuse-sb2-7_11_1-00016-redhat-00002//fuse-console-cluster-rbac.yml`

   • Namespace template:

     `https://github.com/jboss-fuse/application-templates/blob/application-templates-2.1.0.fuse-sb2-7_11_1-00016-redhat-00002//fuse-console-namespace-os4.json`

   • Namespace template with configurable RBAC:

     `https://github.com/jboss-fuse/application-templates/blob/application-templates-2.1.0.fuse-sb2-7_11_1-00016-redhat-00002//fuse-console-namespace-rbac.yml`

     For example, for the cluster template with configurable RBAC, run this command:

     oc process --parameters -f https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-7_11_1-00016-redhat-00002/fuse-console-cluster-rbac.yml

4. From the certificate that you generated in Securing the Fuse Console on OpenShift 4.x, create the secret and mount it in the Fuse Console by using the following command (where APP_NAME is the name of the Fuse Console application).

   oc create secret tls APP_NAME-tls-proxying --cert server.crt --key server.key

5. Create a new application based on your local copy of the Fuse Console template by running the following command (where myproject is the name of your OpenShift project, mytemp is the path to the local directory that contains the Fuse Console template, and myhost is the hostname to access the Fuse Console:

   • For the cluster template:

     oc new-app -n myproject -f https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-7_11_1-00016-redhat-00002/fuse-console-cluster-os4.json  -p ROUTE_HOSTNAME=myhost

   • For the cluster with RBAC template:

     oc new-app -n myproject -f https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-7_11_1-00016-redhat-00002/fuse-console-cluster-rbac.yml -p ROUTE_HOSTNAME=myhost

   • For the namespace template:

     oc new-app -n myproject -f https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-7_11_1-00016-redhat-00002/fuse-console-namespace-os4.json

   • For the namespace with RBAC template:

     oc new-app -n myproject -f https://raw.githubusercontent.com/jboss-fuse/application-templates/application-templates-2.1.0.fuse-sb2-7_11_1-00016-redhat-00002/fuse-console-namespace-rbac.yml

6. To configure the Fuse Console so that it can open the OpenShift Web console, set the OPENSHIFT_WEB_CONSOLE_URL environment variable by running the following command:

   oc set env dc/${APP_NAME} OPENSHIFT_WEB_CONSOLE_URL=`oc get -n openshift-config-managed cm console-public -o jsonpath={.data.consoleURL}`

7. Obtain the status and the URL of your Fuse Console deployment by running this command:

   oc status

8. To access the Fuse Console from a browser, use the URL that is returned in Step 7 (for example, https://fuse-console.192.168.64.12.nip.io).

1. In a terminal window, use the following command to change the .spec.version field of the application custom resource definition:

   oc patch -n <project-name> <custom-resource-name> --type='merge' -p '{"spec":{"version":"1.7.1"}}'

   For example:

   oc patch -n myproject hawtio/example-fuseconsole --type='merge' -p '{"spec":{"version":"1.7.1"}}'

2. Check that the application’s status has updated:

    oc get -n myproject hawtio/example-fuseconsole

   The response shows information about the application, including the version number:

   NAME                  AGE   URL                                        IMAGE
   example-fuseconsole   1m    https://fuseconsole.192.168.64.38.nip.io   docker.io/fuseconsole/online:1.7.1

   When you change the value of the .spec.version field, OpenShift automatically redeploys the application.

3. To check the status of the redeployment that is triggered by the version change:

   oc rollout status deployment.v1.apps/example-fuseconsole

   A successful deployment shows this response:

   deployment "example-fuseconsole" successfully rolled out

Procedure

1. Start the OpenShift 4 Server.

2. Log in to the OpenShift Server as an administrator.

   oc login --user system:admin --token=my-token --server=https://my-cluster.example.com:6443

3. Verify that you are using the project for which you created a docker-registry secret.

   oc project openshift

4. View the current configuration of Samples operator.

   oc get configs.samples.operator.openshift.io -n openshift-cluster-samples-operator -o yaml

5. Configure Samples operator to ignore the fuse templates and image streams that are added.

   oc edit configs.samples.operator.openshift.io -n openshift-cluster-samples-operator

6. Add the Fuse imagestreams Skipped Imagestreams section and add Fuse and Spring Boot 2 templates to Skipped Templates section.
