Chapter 6. Using credentials and configurations in workspaces

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

   https://trailblazer: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@github.com

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

   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

Procedure

1. Copy your access token and encode it to Base64.

   $ echo -n '<your_access_token>' | base64

2. Prepare a new OpenShift Secret in your user project.

   kind: Secret
   apiVersion: v1
   metadata:
     name: personal-access-token-<your_chosen_name_for_this_token>
     labels:
       app.kubernetes.io/component: scm-personal-access-token
       app.kubernetes.io/part-of: che.eclipse.org
     annotations:
       che.eclipse.org/che-userid: <devspaces_user_ID> 1
       che.eclipse.org/scm-personal-access-token-name: <git_provider_name> 2
       che.eclipse.org/scm-url: <Git_provider_endpoint> 3
       che.eclipse.org/scm-userid: <Git_provider_user_ID> 4
       che.eclipse.org/scm-username: <Git_provider_username>
   data:
     token: <Base64_encoded_access_token>
   type: Opaque

   1

   Your Che user ID. You can retrieve <che-endpoint>/api/user to get the Che user data.

   2

   The Git provider name: github or gitlab or bitbucket-server.

   3

   The Git provider URL.

   4

   Your Git provider user ID, follow the API documentation to retrieve the user object:

   • GitHub: Get a user. See the id value in the response.
   • GitLab: List users: For normal users, use the username filter: /users?username=:username. See the id value in the response.
   • Bitbucket Server: Get users. See the id value in the response.

3. Apply the Secret.

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

Procedure

1. In the <username>-devspaces namespace, apply the Secret for the TLS certificate:

   metadata:
     name: tls-cer
     annotations:
       controller.devfile.io/mount-path: /home/user/certs
       controller.devfile.io/mount-as: file
     labels:
       controller.devfile.io/mount-to-devworkspace: 'true'
       controller.devfile.io/watch-secret: 'true'
   data:
     tls.cer: >-
       <Base64_encoded_content_of_public_cert> 1

   1

   Base64 encoding with disabled line wrapping.

2. In the <username>-devspaces namespace, apply the ConfigMap to create the settings.xml file:
