Hi, today I would like to share with you solution to a problem I've encountered when I tried to login to docker container.

My error:

xxxxxxxxxx
 
[root@localhost]# docker exec -ti auth-service /bin/bash
OCI runtime exec failed: exec failed: container_linux.go:349: starting container process caused "exec: \"/bin/bash\": stat /bin/bash: no such file or directory": unknown

Solution

Edit

Solution is quite simple.

xxxxxxxxxx
 
# Use /bin/sh instead of /bin/bash
docker exec -t -i PUT_CONTAINER_NAME_HERE /bin/sh

Explanation:

The docker container didn't have /bin/bash installed, so I used /bin/sh instead and it solved my problem.

Example of correct login to docker container using /bin/sh:

xxxxxxxxxx
 
$ docker exec -ti auth-service /bin/sh

Practical example from CMD:

xxxxxxxxxx
 
[root@localhost]# docker exec -ti auth-service /bin/sh
/ # ls -al
total 43548
drwxr-xr-x    1 root     root            46 Oct  1 18:09 .
drwxr-xr-x    1 root     root            46 Oct  1 18:09 ..
-rwxr-xr-x    1 root     root             0 Oct  1 18:09 .dockerenv
drwxr-xr-x    2 root     root          4096 May  9  2019 bin

Summary

Edit

So to sum up the post, we can login to docker container:

xxxxxxxxxx
 
# Using /bin/sh
docker exec -t -i PUT_CONTAINER_NAME_HERE /bin/sh
​
# Using /bin/bash
# Second option when our linux doesn't have /bin/sh, we need to use another shell /bin/bash
docker exec -t -i PUT_CONTAINER_NAME_HERE /bin/bash
