如何从jenkins SSH进入运行的docker容器执行shell

Question

I am running a docker container ( dind ) from jenkins execute shell

CONTAINER_ID="$(sudo docker run --privileged -i -d jpetazzo/dind)"

To execute docker commands inside container I get into container shell

sudo docker exec -it --privileged ${CONTAINER_ID} bash

and than I am trying to execute these commands inside dind container.

sudo docker pull hubuser/hello-world

sudo docker run hubuser/hello-world

sudo docker tag imageId hubuser/hello-world:123

sudo docker login --username=hubuser --password=password

sudo docker push hubuser/hello-world

All of these 7 commands I have written in jenkins execute shell. Below given 5 commands are executing outside dind container, not inside. If I am trying from terminal than it is attaching to the container shell and executing properly. I want to execute them inside container but from jenkins. I also tried adding exec before every command like this:

sudo docker exec -it --privileged ${CONTAINER_ID} sudo docker pull hubuser/hello-world

sudo docker exec -it --privileged ${CONTAINER_ID} sudo docker run hubuser/hello-world

and so on. This executes commands inside dind container but all commands executes in parallel, so before pulling and running the hello-world image, it tries to tag it and push it. There it is not finding any hello-world image to tag and it does't do anything.

I want all my below 5 commands to execute serially inside dind container, that too from jenkins execute shell.

The title of your post is "how to ssh into running docker". I just want to point out this article, wrote by a Docker engineer: If you run SSHD in your Docker containers, you're doing it wrong!

After I read your post, that is not treating issue with ssh, I just thought about: why not execute a bash-script that does sequentially what you wanted to?

I'm not sure if I understood well btw, is Jenkins inside a docker? Are you running a docker in a docker?
