Docker - connect to container command line
6 points
Hi, today I would like to show you how we can login to docker container command line.
Quick solutions
Using /bin/sh
xxxxxxxxxx1
docker exec -t -i PUT_CONTAINER_NAME_HERE /bin/shUsing /bin/bash
Second option when our linux doesn't have /bin/sh, we need to use another shell /bin/bash
xxxxxxxxxx1
docker exec -t -i PUT_CONTAINER_NAME_HERE /bin/bashIf we don't have /bin/bash then this command will output the error
(OCI runtime exec failed, more here: to problem description and solution)
Practical example when our container name is: auth-service-container.
We simply replace 'PUT_CONTAINER_NAME_HERE' with our container name: 'auth-service-container'.
xxxxxxxxxx1
docker exec -t -i auth-service-container /bin/shOutput from command line:
xxxxxxxxxx1
[root@localhost ~]# docker exec -t -i auth-service-container /bin/sh2
/ # ls -al3
