Creating a Docker image

    The instructions describe how to build a Docker image from a Dockerfile and how to assemble it.

    CLI
    1. Create a file named Dockerfile and add the following lines to it:

      FROM ubuntu:latest
      CMD echo "Hi, I'm inside"
      

      The described Docker image is based on Ubuntu and will execute one simple command.

    2. Assemble the Docker image. As a <registry ID>, use the ID received when creating the registry.

      docker build . \
      -t cr.yandex/<registry ID>/ubuntu:hello
      

      The -t flag assigns a tag like cr.yandex/<registry ID>/<Docker image name>:<tag> to the Docker image. You can build Docker images without any tag. In this case, the Docker CLI assigns them the default label: latest.

    After running these commands, the Docker image will be created with the following parameters:

    • Full address of the repository consisting of:
      • Address of Yandex Container Registry cr.yandex.
      • ID of your registry <registry ID>.
      • Name of your ubuntu repository.
    • Docker image tag in your repository: hello.
