Docker – exec: "bash": executable file not found in $PATH

If bash shell is not working, try sh.

$ docker ps

CONTAINER ID        IMAGE               COMMAND               CREATED             STATUS              PORTS                  NAMES

$ docker exec -it 3d1588519433 bash

OCI runtime exec failed: exec failed: container_linux.go:349:
starting container process caused "exec: \"bash\": executable file not found in $PATH": unknown

The truth is, not every image is using the bash shell; try sh shell.

$ docker exec -it 3d1588519433 sh

/home/hello #
