Docker Helper File

Create the docker-helper.yml in the same directory as docker-compose.yml.

variables:
  DOCKER_ENV: production
  SERVER_HOST: localhost
  SERVER_PORT: 8080

scripts:
  prod: "docker-compose up -d"
  dev: "docker-compose up --force-recreate"
  recreate: "docker-compose rm -sf && docker-compose up -d"
  update: "docker-compose pull && docker-helper recreate"
  force-remove: "docker-compose rm -sf"

hooks:
  init: "mkdir -p $PROJECT_ROOT/hook-test/test1"

Environment

If "DOCKER_ENV" is defined in the .env file or docker-helper.yml, the "docker-compose.<DOCKER_ENV>.yml" and ".env.<DOCKER_ENV>" will be loaded automatically if they exist.

Variables

PROJECT_ROOT: Full path to docker-compose.yml.
PROJECT_NAME: Basename of the project root.
USER_ID: Current user ID.
GROUP_ID: Current user group ID.
DOCKER_GROUP_ID: Docker group ID.

Scripts

Scripts can be created in the "scripts" index in docker-helper.yml or in the "docker-helper.d/scripts/" directory.

You can run a command using a service by running "<service_name>-exec". The container will be created without dependencies and using the "project_root" as a volume keeping the current directory. The container will be removed after execution.

Ex: ./docker-helper nginx-exec /usr/sbin/nginx -v

Hooks

Hooks can be created in the "hooks" index in docker-helper.yml or in the "docker-helper.d/hooks/" directory.
