"docker container start --attach" - Attach Console


How to start a container with its console attached to the host console using the "docker container start --attach" command?

✍: FYIcenter.com


By default, the "docker command start" command will start a container and run its default command in the background. You will not see anything that is printed its console.

If you want to see what is printed and by the container's default program, you need to use the "--attach" option, which attaches the hosting console to the TTY terminal of container's running program.

1. Create a new container from the "hello-world" image.

fyicenter$ docker container create --name second_hello hello-world


2. Start the container with its console attached.

fyicenter$ docker container start --attach second_hello

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

As you can see, the default program from the container printed a nice message to its console.
