docker-compose does not update image

  • 772

I have an image with code that I need to update very often. In order to see the new changes I have to delete the containers and create a new docker-compose.

Is there another way to do it?

docker

    You can upload the version of the containers and deploy them with the new version so you don't have to delete the containers to take the changes

  2. I've been trying many things for a few weeks and the only one that has definitely worked for me is the following:

    docker-compose up -d --force-recreate

    In this way only the images and files with changes are updated and it is not necessary to do the re-build

  3. Containers are automatically deleted when you do:

    docker-compose down

    Maybe you mean to delete the images, for that I would recommend you to build your images inside the docker-compose.

    So:

    version: "3.9"
services:
  webapp:
    build: ./dir

    Or something more advanced like:

    version: "3.9"
services:
  webapp:
    build:
      context: ./dir
      dockerfile: Dockerfile-alternate
      args:
        buildno: 1

    You can see more details at: https://docs.docker.com/compose/compose-file/compose-file-v3/#build
