Jenkins configuration as a code

Jenkins master configuration as a code for my personal Jenkins instance.

Deployment

docker and docker-compose is needed to deploy Jenkins master with docker-plugin cloud.

Environment variables

Firstly run following command to populate environment variables:

cp -R .envs/.dist .envs/.production

Then edit it carefully and fill all required values (environment variables with !!SET_VALUE!! value):

• .envs/.production/.master:
  • VIRTUAL_HOST - Jenkins' master host

Secrets

Populate all secrets defined in docker-compose.yml:

• .secrets/admin_password - Jenkins' admin password
• .secrets/docker_hub__skarzi - properly encrypted by Jenkins, personal access token or password to skarzi docker hub where Jenkins' slave image is hosted

Docker compose override

Create docker-compose.override.yml:

cp docker-compose.override.yml.example docker-compose.override.yml

Now fill all required values (with !!SET_VALUE!! value) inside newly created file:

• DOCKER_GID - docker group GID from your system. You can get this value by checking it in /etc/group file or running following command: getent group docker | cut -d : -f 3

Run services

Use docker-compose to run Jenkins' master and slaves behind nginx reverse proxy.
