To setup log rotation on docker compose simply add this

logging:
  driver: "json-file"
  options:
    max-size: "1k"
    max-file: "3"

so example docker-compose.yml file

database:
  image: postgres:14.5-alpine
  restart: always
  ports:
    - "5432:5432"
  environment:
    POSTGRES_USER: user
  volumes:
    - ./data:/var/lib/postgresql/data:rw
  logging:
    driver: "json-file"
    options:
      max-size: "1k"
      max-file: "3"

I’ve recently started using a private docker registry for some docker images i’ve been using for certain projects that require special setup.

To create the image

docker build -t docker.example.com/directory/image:tag .

Then I find the ID of the image using

docker image ls

Then when i’ve got the image ID I can tag the image

docker tag 12345678 docker.example.com/directory/image:tag

After that I can then push to the repository

docker push docker.example.com/directory/image:tag
