bash: docker: command not found

I'm accessing Ubuntu 19.10 running as a virtual machine. In the installation process I installed Docker (as a snap). Everything is fine when I log in using SSH, but this will fail:

$ ssh user@host 'docker info'

returning: bash: docker: command not found. Other commands like $ ssh user@host date or $ ssh user@host 'ls -l' woks fine.

Any suggestions?

Create a symlink:

sudo ln -s /snap/bin/docker /usr/bin/docker

You could also check what your path variable shows using the same command, but instead of ls -l use echo $PATH command. You could try to place symlinks to PATH mentioned there.

Set the PATH on the server in ~/.ssh/environment (needs to be enabled by PermitUserEnvironment yes in sshd_config).
