Required Configuration

Before deploying, you must:

1. Create Renovate Bot User in Gitea:

   • Username: renovate-bot
   • Email: renovate-bot@bsdserver.nl
   • Full name: "Renovate Bot"

2. Generate Personal Access Token with scopes:

   • repo (Read and Write)
   • user (Read)
   • issue (Read and Write)
   • organization (Read)

3. Update terraform.tfvars:

   renovate_endpoint   = "https://gitea.bsdserver.nl/api/v1/"
   renovate_token      = "your-actual-token-here"
   renovate_git_author = "Renovate Bot <renovate-bot@bsdserver.nl>"
   renovate_username   = "renovate-bot"
   

4. Initialize Terraform:

   terraform init
   terraform plan
   terraform apply
   

Next Steps

1. Deploy the Module:

   cd /path/to/terraform-docker-renovate
   terraform init
   terraform plan
   terraform apply
   

2. Verify Deployment:

   docker ps | grep renovate
   docker logs renovate -f
   

3. Configure Repositories:

   • Add renovate.json to each repository
   • Use files/example-renovate.json as a template
   • Enable autodiscovery or add bot as collaborator

4. Set Up Scheduling:

   • Configure cron job
   • Or use Gitea Actions workflow
   • See files/example-gitea-workflow.yaml

5. Monitor and Test:

   • Wait for Renovate to create onboarding PRs
   • Review and merge onboarding PRs
   • Monitor dependency update PRs
