Procedure

1. Place the che-editor.yaml file in the .che folder in the root directory of your project.

2. In the che-editor.yaml file, specify the ID of the IDE you are selecting. For example:

   id: che-incubator/che-idea/latest

Procedure

1. In your home directory, locate and open your .git-credentials file if you already have it. Alternatively, if you do not have this file, save a new .git-credentials file, using the Git credentials storage format. Each credential is stored on its own line in the file:

   https://<username>:<token>@<git_server_hostname>

   Example 6.1. A line in a .git-credentials file

2. Select credentials from your .git-credentials file for the Secret. Encode the selected credentials to Base64 for the next step.

   Tip

   • To encode all lines in the file:

     $ cat .git-credentials | base64 | tr -d '\n'

   • To encode a selected line:

     $ echo -n '<copied_and_pasted_line_from_.git-credentials>' | base64

3. Create a new OpenShift Secret in your user project.

   apiVersion: v1
   kind: Secret
   metadata:
     name: git-credentials-secret
     labels:
       controller.devfile.io/git-credential: 'true' 

   1

   
       controller.devfile.io/watch-secret: 'true'
     annotations:
       controller.devfile.io/mount-path: /etc/secret 

   2

   
   data:
     credentials: <Base64_content_of_.git-credentials> 

   3

   Copy to Clipboard Toggle word wrap

   1

   The controller.devfile.io/git-credential label marks the Secret as containing Git credentials.

   2

   A custom absolute path in the DevWorkspace containers. The Secret is mounted as the credentials file at this path. The default path is /.

   3

   The selected content from .git-credentials that you encoded to Base64 in the previous step.

   Tip

   You can create and apply multiple Git credentials Secrets in your user project. All of them will be copied into one Secret that will be mounted to the DevWorkspace containers. For example, if you set the mount path to /etc/secret, then the one Secret with all of your Git credentials will be mounted at /etc/secret/credentials. You must set all Git credentials Secrets in your user project to the same mount path. You can set the mount path to an arbitrary path because the mount path will be automatically set in the Git configuration file configured at /etc/gitconfig.

4. Apply the Secret.

   $ oc apply -f - <<EOF
   <Secret_prepared_in_the_previous_step>
   EOF

2. Click the OpenShift Dev Spaces link to open the Dev Spaces Dashboard.

Procedure

1. Using Dashboard, try to start a workspace.
2. When it fails to start, click on the displayed Open in Verbose mode link.
3. Check the Logs tab to find a reason for the workspace failure.

Procedure

1. Open the Workspaces tab.
2. On the left side of a row dedicated to the workspace, access the drop-down menu displayed as three horizontal dots and select the Open in Verbose mode option. Alternatively, this option is also available in the workspace details, under the Actions drop-down menu.
3. Check the Logs tab to find a reason for the workspace failure.

Prerequisites

1. You have the .che/che-theia-plugins.yaml file in the root of the GitHub repository.

Procedure

1. Add the ID of the plug-in to the .che/che-theia-plugins.yaml file. Use the / sign to separate the publisher and plug-in name. The following example uses the IDs of Red Hat Visual Studio Code Java extension:

   - id: redhat/java/latest

   Copy to Clipboard Toggle word wrap

Prerequisites

1. You have the .che/che-theia-plugins.yaml file in the root of the GitHub repository.

Procedure

1. Add an override section to the .che/che-theia-plugins.yaml file under the id of the plug-in.

2. Specify the memory limit for the extension. In the following example, OpenShift Dev Spaces automatically installs the Red Hat Visual Studio Code Java extension in the OpenShift Dev Spaces workspace and increases the memory of the workspace by two gigabytes:

     - id: redhat/java/latest
       override:
         sidecar:
           memoryLimit: 2Gi

Prerequisites

1. You have the .che/che-theia-plugins.yaml file in the root of the GitHub repository.

Procedure

1. Add an override section to the .che/che-theia-plugins.yaml file under the id of the extension.

2. Specify the preferences in the Preferences section. In the following example, OpenShift Dev Spaces automatically installs Red Hat Visual Studio Code Java extension in the OpenShift Dev Spaces workspace and sets the java.server.launchMode preference to LightWeight:

     - id: redhat/java/latest
       override:
         preferences:
           java.server.launchMode: LightWeight

Procedure

1. Add an attributes section to your devfile.yaml file.
2. Add .vscode/extensions.json to the atributes section. Add a | sign after the colon separator.
