Chapter 6. Using credentials and configurations in workspaces


You can use your credentials and configurations in your workspaces.

To do so, mount your credentials and configurations to the Dev Workspace containers in the OpenShift cluster of your organization’s OpenShift Dev Spaces instance:

  • Mount your credentials and sensitive configurations as Kubernetes Secrets.
  • Mount your non-sensitve configurations as Kubernetes ConfigMaps.

If you need to allow the Dev Workspace Pods in the cluster to access container registries that require authentication, create an image pull Secret for the Dev Workspace Pods.

The mounting process uses the standard Kubernetes mounting mechanism and requires applying additional labels and annotations to your existing resources. Resources are mounted when starting a new workspace or restarting an existing one.

You can create permanent mount points for various components:

  • Maven configuration, such as the user-specific settings.xml file
  • SSH key pairs
  • AWS authorization tokens
  • Configuration files
  • Persistent storage
  • Git credentials

6.1. Using Git credentials

As an alternative to the OAuth for GitHub, GitLab, or Bitbucket that is configured by the administrator of your organization’s OpenShift Dev Spaces instance, you can apply your Git credentials, a credentials store and access token, as Kubernetes Secrets.

6.1.1. Using a Git credentials store

If the administrator of your organization’s OpenShift Dev Spaces instance has not configured OAuth for GitHub, GitLab, or Bitbucket, you can apply your Git credentials store as a Kubernetes Secret.

Mounting your Git credentials store as a Secret results in the Dev Workspace Operator applying your Git credentials to the .gitconfig file in the workspace container.

Apply the Kubernetes Secret in your user project of the OpenShift cluster of your organization’s OpenShift Dev Spaces instance.

When you apply the Secret, a Git configuration file with the path to the mounted Git credentials store is automatically configured and mounted to the Dev Workspace containers in the cluster at /etc/gitconfig. This makes your Git credentials store available in your workspaces.

Prerequisites

  • An active oc session, with administrative permissions, to the OpenShift cluster. See Getting started with the CLI.
  • The base64 command line tools are installed in the operating system you are using.

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 Dev Workspace 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 Dev Workspace 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

6.1.2. Using a Git provider access token

If the administrator of your organization’s OpenShift Dev Spaces instance has not configured OAuth for GitHub, GitLab, or Bitbucket, you can apply your personal access token as a Kubernetes Secret.

Mounting your access token as a Secret enables the OpenShift Dev Spaces Server to access the remote repository that is cloned during workspace creation, including access to the repository’s /.che and /.vscode folders.

Apply the Kubernetes Secret in your user project of the OpenShift cluster of your organization’s OpenShift Dev Spaces instance.

After you have applied the Secret, you can create new workspaces from a private GitHub, GitLab, or Bitbucket-server repository.

Tip

In your user project, you can create and apply multiple access-token Secrets per a Git provider.

Prerequisites

  • An active oc session, with administrative permissions, to the OpenShift cluster. See Getting started with the CLI.
  • The base64 command line tools are installed in the operating system you are using.

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 OpenShift Dev Spaces user ID. You can retrieve <che_endpoint>/api/user to get the OpenShift Dev Spaces 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

6.3. Creating image pull Secrets

To allow the Dev Workspace Pods in the OpenShift cluster of your organization’s OpenShift Dev Spaces instance to access container registries that require authentication, create an image pull Secret.

You can create image pull Secrets by using oc or a .dockercfg file or a config.json file.

6.3.1. Creating an image pull Secret with oc

Prerequisites

Procedure

  1. In your user project, create an image pull Secret with your private container registry details and credentials:

    $ oc create secret docker-registry <Secret_name> \
        --docker-server=<registry_server> \
        --docker-username=<username> \
        --docker-password=<password> \
        --docker-email=<email_address>
  2. Add the following label to the image pull Secret:

    $ oc label secret <Secret_name> controller.devfile.io/devworkspace_pullsecret=true controller.devfile.io/watch-secret=true

6.3.2. Creating an image pull Secret from a .dockercfg file

If you already store the credentials for the private container registry in a .dockercfg file, you can use that file to create an image pull Secret.

Prerequisites

  • An active oc session with administrative permissions to the destination OpenShift cluster. See Getting started with the CLI.
  • base64 command line tools are installed in the operating system you are using.

Procedure

  1. Encode the .dockercfg file to Base64:

    $ cat .dockercfg | base64 | tr -d '\n'
  2. Create a new OpenShift Secret in your user project:

    apiVersion: v1
    kind: Secret
    metadata:
      name: <Secret_name>
      labels:
        controller.devfile.io/devworkspace_pullsecret: 'true'
        controller.devfile.io/watch-secret: 'true'
    data:
      .dockercfg: <Base64_content_of_.dockercfg>
    type: kubernetes.io/dockercfg
  3. Apply the Secret:

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

6.3.3. Creating an image pull Secret from a config.json file

If you already store the credentials for the private container registry in a $HOME/.docker/config.json file, you can use that file to create an image pull Secret.

Prerequisites

  • An active oc session with administrative permissions to the destination OpenShift cluster. See Getting started with the CLI.
  • base64 command line tools are installed in the operating system you are using.

Procedure

  1. Encode the $HOME/.docker/config.json file to Base64.

    $ cat config.json | base64 | tr -d '\n'
  2. Create a new OpenShift Secret in your user project:

    apiVersion: v1
    kind: Secret
    metadata:
      name: <Secret_name>
      labels:
        controller.devfile.io/devworkspace_pullsecret: 'true'
        controller.devfile.io/watch-secret: 'true'
    data:
      .dockerconfigjson: <Base64_content_of_config.json>
    type: kubernetes.io/dockerconfigjson
  3. Apply the Secret:

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

6.4. Mounting Secrets

To mount confidential data into your workspaces, use Kubernetes Secrets.

Using Kubernetes Secrets, you can mount usernames, passwords, SSH key pairs, authentication tokens (for example, for AWS), and sensitive configurations.

Mount Kubernetes Secrets to the Dev Workspace containers in the OpenShift cluster of your organization’s OpenShift Dev Spaces instance.

Prerequisites

  • An active oc session with administrative permissions to the destination OpenShift cluster. See Getting started with the CLI.
  • In your user project, you created a new Secret or determined an existing Secret to mount to all Dev Workspace containers.

Procedure

  1. Add the labels, which are required for mounting the Secret, to the Secret.

    $ oc label secret <Secret_name> \
            controller.devfile.io/mount-to-devworkspace=true \
            controller.devfile.io/watch-secret=true
  2. Optional: Use the annotations to configure how the Secret is mounted.

    Table 6.1. Optional annotations
    AnnotationDescription

    controller.devfile.io/mount-path:

    Specifies the mount path.

    Defaults to /etc/secret/<Secret_name>.

    controller.devfile.io/mount-as:

    Specifies how the resource should be mounted: file, subpath, or env.

    Defaults to file.

    mount-as: file mounts the keys and values as files within the mount path.

    mount-as: subpath mounts the keys and values within the mount path using subpath volume mounts.

    mount-as: env mounts the keys and values as environment variables in all Dev Workspace containers.

Example 6.2. Mounting a Secret as a file

apiVersion: v1
kind: Secret
metadata:
  name: mvn-settings-secret
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-secret: 'true'
  annotations:
    controller.devfile.io/mount-path: '/home/user/.m2'
data:
  settings.xml: <Base64_encoded_content>

When you start a workspace, the /home/user/.m2/settings.xml file will be available in the Dev Workspace containers.

With Maven, you can set a custom path for the settings.xml file. For example:

$ mvn --settings /home/user/.m2/settings.xml clean install

6.5. Mounting ConfigMaps

To mount non-confidential configuration data into your workspaces, use Kubernetes ConfigMaps.

Using Kubernetes ConfigMaps, you can mount non-sensitive data such as configuration values for an application.

Mount Kubernetes ConfigMaps to the Dev Workspace containers in the OpenShift cluster of your organization’s OpenShift Dev Spaces instance.

Prerequisites

  • An active oc session with administrative permissions to the destination OpenShift cluster. See Getting started with the CLI.
  • In your user project, you created a new ConfigMap or determined an existing ConfigMap to mount to all Dev Workspace containers.

Procedure

  1. Add the labels, which are required for mounting the ConfigMap, to the ConfigMap.

    $ oc label configmap <ConfigMap_name> \
            controller.devfile.io/mount-to-devworkspace=true \
            controller.devfile.io/watch-configmap=true
  2. Optional: Use the annotations to configure how the ConfigMap is mounted.

    Table 6.2. Optional annotations
    AnnotationDescription

    controller.devfile.io/mount-path:

    Specifies the mount path.

    Defaults to /etc/config/<ConfigMap_name>.

    controller.devfile.io/mount-as:

    Specifies how the resource should be mounted: file, subpath, or env.

    Defaults to file.

    mount-as:file mounts the keys and values as files within the mount path.

    mount-as:subpath mounts the keys and values within the mount path using subpath volume mounts.

    mount-as:env mounts the keys and values as environment variables in all Dev Workspace containers.

Example 6.3. Mounting a ConfigMap as environment variables

kind: ConfigMap
apiVersion: v1
metadata:
  name: my-settings
  labels:
    controller.devfile.io/mount-to-devworkspace: 'true'
    controller.devfile.io/watch-configmap: 'true'
  annotations:
    controller.devfile.io/mount-as: env
data:
  <env_var_1>: <value_1>
  <env_var_2>: <value_2>

When you start a workspace, the <env_var_1> and <env_var_2> environment variables will be available in the Dev Workspace containers.
