I have a dedicated server with LXD installed where I have a bunch of system containers running to host a lot of my playground services, and to access the operating system of those lxc containers, I need to SSH to the LXD host, then exec or ssh into that LXC container.
This became tedious and wanted a way to directly ssh to them, as they don't have public ip addresses, it's not possible but found its possible to access them using proxyjump.
[you] -> [hypervisor] -> [vm on hypervisor]
First step is to create our ssh key:
$ ssh-keygen -t rsa
Add the created public key (~/.ssh/id_rsa.pub
) on the hypervisor and the target vm's ~/.ssh/authorized_key
files.
Then create the SSH Config on your local workstation (~/.ssh/config
):
Host *
StrictHostKeyChecking no
UserKnownHostsFile=/dev/null
Host hypervisor
Hostname hv.domain.com
User myuser
IdentityFile ~/.ssh/id_rsa
Host ctr1
Hostname 10.37.117.132
User root
IdentityFile ~/.ssh/id_rsa
ProxyJump hypervisor
Now accessing our lxc container ctr1, is possible by doing:
$ ssh ctr1
