how to ssh docker container
DockerSshDocker Problem Overview
I am running the container hypriot/rpi-busybox-httpd
I am trying to ssh to docker container: but it is giving error :
pi@raspberrypi:~ $ docker exec -it cc55da85b915 bash
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "exec: \"bash\": executable file not found in $PATH"
pi@raspberrypi:~ $ docker exec -it cc55da85b915 sh
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "exec: \"sh\": executable file not found in $PATH"
am I doing the right away ?
Docker Solutions
Solution 1 - Docker
It could be your image does not have the binary /bin/bash installed (as suggested before), I had the same problem and I was able to enter into the container using /bin/sh
docker exec -ti cc55da85b915 /bin/sh
Another workaround could be execute directly the commands without get access to any shell.
docker exec -ti cc55da85b915 ls /etc
Solution 2 - Docker
The image you're using seems that it doesn't have the binary /bin/bash installed but it should have /bin/sh
Try:
docker exec -it cc55da85b915 sh
Solution 3 - Docker
You have many different ways to do that, you can attach using docker's attach command.
$ sudo docker attach cc55da85b915 #by ID
Or you can use docker exec command:
$ sudo docker exec -i -t cc55da85b915 /bin/bash
If /bin/bash
fails, you can use /bin/sh
that works in more containers:
$ sudo docker exec -i -t cc55da85b915 /bin/sh
Solution 4 - Docker
You might need to specify the full path to bash
, e.g.:
docker exec -it cc55da85b915 /bin/bash
or /usr/local/bin/bash
, or wherever bash is located in that image.
Hope this helps!
Solution 5 - Docker
if you are still looking for an answer. This worked for me on windows.
winpty docker exec -it <containerid> sh
Solution 6 - Docker
For Alpine based image, docker exec -ti cc55da85b915 /bin/sh and docker exec -ti cc55da85b915 ls /etc worked. As suggested by 'Esteban Collado'.
However for other Linux versions I use, docker exec -ti cc55da85b915 bash
Solution 7 - Docker
Try Below Command:
docker exec -it cc55da85b915 /bin/busybox sh
To list all the available commands use:
docker exec -it cc55da85b915 /bin/busybox --list
Solution 8 - Docker
This will also relevant for Kubernetes pods.
For example if you'll try to connect to a pod which doesn't contain the shell you specified:
kubectl exec -it some-busybox-pod bash
(busybox have sh
on it not bash
).
You'll end up with the same error:
OCI runtime exec failed: exec failed: container_linux.go:349: starting container process caused "exec: \"bash\": executable file not found in $PATH": unknown
command terminated with exit code 126
