"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?
By default, the "docker command start" command will start a container and run it in the background. You will not see anything that is printed its console.
If you want to see what is printed to STDOUT and STDERR by the container's default program, you need to use the "--attach" option.
1. Create a new container from the "hello-world" image.
$ docker container create --name second_hello hello-world 09d20b3c758032e6b8dff5784c564e2c25edf4e4fd64ec29fcc085207b6428ac
2. Start the container with its console attached.
$ 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. (amd64) 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 Share images, automate workflows, and more with a free Docker ID: https://hub.docker.com/ For more examples and ideas, visit: https://docs.docker.com/get-started/
As you can see, the default program from the container printed a nice message to its console.
