I tried to run aws cli image from amazon from docker-compose.

version: '3.1'
services:
    web:
        image: amazon/aws-cli:latest
        stdin_open: true # equivalent of -i
        tty: true        # equivalent of -t
        deploy:
          mode: replicated
          replicas: 1
          resources:
            limits:
              cpus: "2"
              memory: 2048M
          restart_policy:
            condition: on-failure
            delay: 5s
            max_attempts: 3
            window: 120s
        environment:
          - HTTP_PROXY=http://ipadresses:port
          - HTTPS_PROXY=https://ipadresses:port
        ports:
            - "8080:8080"

After one second, the image stops running immediately. I looked for the official documentation from amazon but I cannot find an answer to my question: why it's stop so quickely Could someone please help me understand this behavior?

CodePudding user response：

amazon/aws-cli:latest is a docker image that provides only the aws command as starting command, which means, if you don't override the command executed by docker the container will execute aws command and stop the execution.

To execute commands against aws using that docker image you need to provide your command e.g. in this compose file I'm executing aws help by adding command: help to the file.

    version: '3.1'
services:
    web:
        image: amazon/aws-cli:latest
        stdin_open: true # equivalent of -i
        tty: true        # equivalent of -t
        command: help
        deploy:
          mode: replicated
          replicas: 1
          resources:
            limits:
              cpus: "2"
              memory: 2048M
          restart_policy:
            condition: on-failure
            delay: 5s
            max_attempts: 3
            window: 120s
        environment:
          - HTTP_PROXY=http://ipadresses:port
          - HTTPS_PROXY=https://ipadresses:port
        ports:
            - "8080:8080"

Alternatively you could override entrypoint to force the container to stay alive, so afterwards you can exec commands against your container e.g

version: '3.1'
services:
    web:
        image: amazon/aws-cli:latest
        stdin_open: true # equivalent of -i
        tty: true        # equivalent of -t
        entrypoint: tail -f /dev/null
        deploy:
          mode: replicated
          replicas: 1
          resources:
            limits:
              cpus: "2"
              memory: 2048M
          restart_policy:
            condition: on-failure
            delay: 5s
            max_attempts: 3
            window: 120s
        environment:
          - HTTP_PROXY=http://ipadresses:port
          - HTTPS_PROXY=https://ipadresses:port
        ports:
            - "8080:8080"

After you run this compose file (in another terminal) you can inspect the name of the created container with docker ps and then execute commands against that using docker exec -it <your_container_name> aws help (note that in this case I'm sending the command aws help to the running container)
