spawn throwaway systemd or non-systemd based docker containers using ssh.
sshcont:
-bind string
bind address, 127.0.0.1:2222, use :2222 for all (default "127.0.0.1:2222")
-cmd string
Execute cmd after login, example: ls
-endpoint string
Docker endpoint. Default: use environment settings. Example: tcp://192.168.1.100:2375
-export string
Before removing, export container contents to specified directory, example: /tmp/
-image string
Force image to be executed
-vol string
Share volume into container, example: /home/:/home_shared
after starting the service, use the following ssh command to start and enter an container:
ssh -l "jrei/systemd-debian" -o StrictHostKeychecking=no localhost -p 2222
root@89fb0de78a12:/
or likewise:
RHEL:
ssh -l "registry.access.redhat.com/ubi9/ubi-init:latest" -o StrictHostKeychecking=no localhost -p 2222
root@89fb0de78a14:/
SLES:
ssh -l "registry.suse.com/bci/bci-init:15.6" -o StrictHostKeychecking=no localhost -p 2222
root@89fb0de78a15:/
regular:
ssh -l "debian:bookworm" -o StrictHostKeychecking=no localhost -p 2222
root@89fb0de78a16:/
ssh -l "alpine:latest" -o StrictHostKeychecking=no localhost -p 2222
root@89fb0de78a17:/
Execute predefined script by using the cmd option:
cat /tmp/ci/test.sh
#!/bin/bash
exit 1
sshcon -vol /tmp/ci:/ci -cmd /ci/test.sh
user@host: ~ $ ssh -l "debian:bookworm" -o StrictHostKeychecking=no localhost -p 2222
Connection to localhost closed.
user@host: ~ $ echo $?
1
on multiple containers:
for dist in $(echo "debian:bookworm" "debian:buster" "debian:bullseye"
"alpine:latest" "registry.suse.com/bci/bci-init:15.6"); do
ssh -l "$dist" -o StrictHostKeychecking=no localhost -p 2222;
done
or directly execute a command via ssh call:
ssh -l "debian:bookworm" -o StrictHostKeychecking=no localhost -p 2222 ls; echo $?
bin dev home lib64 mnt proc run srv tmp var

- No authentication implemented, you should not run this on a public network interface.
- Container images not available on the host will be pulled.
- Container is removed after exiting the session.
- I know containerssh exists, but it brings way too much features i dont need.
- Sometimes i work on systems where docker is not available but need quick access to an container for testing.
