Che 7 IDE in CRW 1.2 - RHDEVDOCS-1249

HOWTO.Che7-in-CRW1.2-OCP4.adoc

(Addendum to CRW 1.2 Guide for using Che 7 IDE in CRW deployment - https://access.redhat.com/documentation/en-us/red_hat_codeready_workspaces/1.2/html-single/administration_guide/index#using-the-che-7-ide-in-codeready-workspaces )

1. Deploy CRW 1.2 to OCP using OperatorHub.

2. Or, use the Operator-based deploy script:

   git clone https://github.com/redhat-developer/codeready-workspaces-deprecated && cd codeready-workspaces-deprecated/operator-installer && git checkout 6.19.x
   ./deploy.sh -d --server-image=quay.io/crw/server-rhel8 -v=1.2-35 --operator-image=quay.io/crw/operator-rhel8:1.2-13 --verbose -p=crw-che7d

3. Get the che plugin registry sources that include the v1 and v2 registries:

   git clone https://github.com/eclipse/che-plugin-registry.git && \
   cd che-plugin-registry && \
   git checkout registry-v2

4. Build it & push to quay (or use my image)

   docker build . -t quay.io/nickboldt/che-plugin-registry-v2:nightly && \
   docker push quay.io/nickboldt/che-plugin-registry-v2:nightly

5. If you deployed your own, go to the Settings tab for your quay repo, eg., https://quay.io/repository/nickboldt/che-plugin-registry-v2?tab=settings. Mark the image public.

6. Deploy the new registry to your cluster, in the same project as CRW deployment, using the image you built above.

   oc login <my cluster>
   oc project <my crw deployment>
   
   cd che-plugin-registry; oc new-app --name=che-plugin-registry -f openshift/che-plugin-registry.yml \
              -p IMAGE="quay.io/nickboldt/che-plugin-registry-v2" \
              -p IMAGE_TAG="nightly" \
              -p PULL_POLICY="Always"

7. Update the CRW deployment to use the new registry:

   routebits=$(oc get routes | grep plugin-registry) && \
   route=( $routebits ) && regurl=${route[1]} && echo $regurl
   
   for d in codeready-operator codeready; do
     oc set env deployment/${d} \
     CHE_WORKSPACE_PLUGIN__REGISTRY__URL=${regurl} && \
     oc scale deployment/${d} --replicas=0 && \
     oc scale deployment/${d} --replicas=1
   done

8. Verify the correct registry is defined in the CodeReady Workspaces server pod:

   oc rsh $(oc get pods | grep codeready | grep -v operator | grep Running | sed -e "s# \+1/1.\+##") /bin/bash -c "env | grep CHE_WORKSPACE_PLUGIN__REGISTRY__URL"

9. Browse to your CRW dashboard, eg., at http://codeready-crw-che7d.apps.crw.codereadyqe.com/dashboard/#/

10. Create a new workspace, eg. the Java 8 one. Instead of starting the workspace, click the menu next to Create & Open and select Create & Proceed Editing. Select the Config tab and edit the default config to remove the installers and add these plugins/editors:

    "attributes": {
          "editor": "org.eclipse.che.editor.theia:next",
          "plugins": "che-machine-exec-plugin:0.0.1,ms-vscode.node-debug2:1.31.6,redhat.vscode-yaml:0.4.0,redhat.vscode-openshift-connector:0.0.19"
        },

    The result should be something like this:

    {
      "defaultEnv": "default",
      "environments": {
        "default": {
          "machines": {

                }
              },
              "volumes": {
                "m2": {
                  "path": "/home/jboss/.m2"

                "javadata": {
                  "path": "/home/jboss/jdtls/data"
                }
              },
              "installers": [],
              "env": {}
            }
          },
          "recipe": {
            "type": "dockerimage",
            "content": "registry.redhat.io/codeready-workspaces/stacks-java-rhel8"
          }
        }
      },
      "projects": [],
      "name": "wksp-e1wz",
      "attributes": {

      },
      "commands": [
        {
          "commandLine": "mvn clean install -f ${current.project.path}/pom.xml",
          "name": "build",
          "attributes": {
            "goal": "Build",
            "previewUrl": ""
          },
          "type": "mvn"
        },
        {
          "commandLine": "${HOME}/stack-analysis.sh -f ${current.project.path}/pom.xml -p ${current.project.path}",
          "name": "dependency_analysis",
          "attributes": {
            "goal": "Run",
            "previewUrl": ""
          },
          "type": "custom"
        }
      ],
      "links": []
    }

11. Open the new workspace. Voila, Che 7 IDE in CRW 1.2!

I love that Voila! +5 points for Nick

Haha, thanks. Now we just need to actually figure out the steps for this to work. :(

The walkthru above doesn't work for me.
