GitLab

CoDev Code integrates with your GitLab workflow through your GitLab CI/CD pipeline or with GitLab Duo.

In both cases, CoDev Code will run on your GitLab runners.

GitLab CI

CoDev Code works in a regular GitLab pipeline. You can build it into a pipeline as a CI component

Here we are using a community-created CI/CD component for CoDev Code — nagyv/gitlab-opencode.

Features

• Use custom configuration per job: Configure CoDev Code with a custom configuration directory, for example ./config/#custom-directory to enable or disable functionality per CoDev Code invocation.
• Minimal setup: The CI component sets up CoDev Code in the background, you only need to create the CoDev Code configuration and the initial prompt.
• Flexible: The CI component supports several inputs for customizing its behavior

Setup

1. Store your CoDev Code authentication JSON as a File type CI environment variables under Settings > CI/CD > Variables. Make sure to mark them as "Masked and hidden".

2. Add the following to your .gitlab-ci.yml file.

   include:
     - component: $CI_SERVER_FQDN/nagyv/gitlab-opencode/opencode@2
       inputs:
         config_dir: ${CI_PROJECT_DIR}/opencode-config
         auth_json: $CODEV_AUTH_JSON # The variable name for your CoDev Code authentication JSON
         command: optional-custom-command
         message: "Your prompt here"

For more inputs and use cases check out the docs for this component.

GitLab Duo

CoDev Code integrates with your GitLab workflow. Mention @opencode in a comment, and CoDev Code will execute tasks within your GitLab CI pipeline.

Features

• Triage issues: Ask CoDev Code to look into an issue and explain it to you.
• Fix and implement: Ask CoDev Code to fix an issue or implement a feature. It will create a new branch and raise a merge request with the changes.
• Secure: CoDev Code runs on your GitLab runners.

Setup

CoDev Code runs in your GitLab CI/CD pipeline, here's what you'll need to set it up:

1. Configure your GitLab environment

2. Set up CI/CD

3. Get an AI model provider API key

4. Create a service account

5. Configure CI/CD variables

6. Create a flow config file, here's an example:

   Flow configuration

   image: node:22-slim
   commands:
     - echo "Installing CoDev Code"
     - npm install --global codev-code
     - echo "Installing glab"
     - export GITLAB_TOKEN=$GITLAB_TOKEN_OPENCODE
     - apt-get update --quiet && apt-get install --yes curl wget gpg git && rm --recursive --force /var/lib/apt/lists/*
     - curl --silent --show-error --location "https://raw.githubusercontent.com/upciti/wakemeops/main/assets/install_repository" | bash
     - apt-get install --yes glab
     - echo "Configuring glab"
     - echo $GITLAB_HOST
     - echo "Creating CoDev Code auth configuration"
     - mkdir --parents ~/.local/share/codev

       }
       EOF
     - echo "Configuring git"
     - git config --global user.email "opencode@gitlab.com"
     - git config --global user.name "CoDev Code"
     - echo "Testing glab"
     - glab issue list
     - echo "Running CoDev Code"

Examples

Here are some examples of how you can use CoDev Code in GitLab.

• Explain an issue

  Add this comment in a GitLab issue.

  @opencode explain this issue

  CoDev Code will read the issue and reply with a clear explanation.

• Fix an issue

  In a GitLab issue, say:

  @opencode fix this

  CoDev Code will create a new branch, implement the changes, and open a merge request with the changes.

• Review merge requests

  Leave the following comment on a GitLab merge request.

  @opencode review this merge request

  CoDev Code will review the merge request and provide feedback.
