Testing

Requirements

To test the changes, you need a local Kubernetes development environment.

Follow https://docs.gitlab.com/charts/development/minikube/ to install Minikube.

You can skip the Deploying the chart section.

Steps

1. Clone this repository

git clone git@gitlab.com:gitlab-org/charts/gitlab.git charts-gitlab

cd charts-gitlab

2. git checkout --track origin/562377-add-database-traffic-capture-config

3. Run

helm dependency update

4. Edit example/values-minikube.yaml and include the config under global:

global:
  ...
  appConfig:
    databaseTrafficCapture:
      config:
        storage:
          connector:
            provider: Gcs
            projectId: project-one
            credentials: /tmp/credentials.json
            bucket: bucket-one

5. Deploy GitLab using Helm

helm upgrade --install gitlab . --timeout 900s -f examples/values-minikube.yaml --set prometheus.install=false --set gitlab-runner.install=false --set=global.grafana.enabled=false --set global.image.pullPolicy=Always --set global.gitlabVersion=master --set global.hosts.domain=$(minikube ip).nip.io --set global.hosts.externalIP=$(minikube ip)

6. Find the web service pod with kubectl get pods
7. Shell into the pod with kubectl exec -ti gitlab-webservice-default-<ID> -- bash
8. cd /srv/gitlab
9. Check that the config was applied to config/gitlab.yml

less config/gitlab.yml

database_traffic_capture:
    config:
      storage:
        connector:
          provider: "Gcs"
          project_id: "project-one"
          credentials: "/tmp/credentials.json"
          bucket: "bucket-one"

10. Access the Rails console with ./bin/rails c and check the application Settings

Settings.database_traffic_capture

=> <GitlabSettings::Options:0x0000ffff728e4d48 @options={"config"=>#<GitlabSettings::Options:0x0000ffff728e4dc0 @options={"storage"=>#<GitlabSettings::Options:0x0000ffff728e4e38 @options={"connector"=>#<GitlabSettings::Options:0x0000ffff728e5018 @options={"provider"=>"Gcs", "project_id"=>"project-one", "credentials"=>"/tmp/credentials.json", "bucket"=>"bucket-one"}>}>}>}>
