Dependencies to connect to a remote docker container in VSCode?

So, it appears that docker must be installed on the host machine to prevent the last mentioned error.

Note: docker service does not need to be running in the host (systemctl disable docker)

With this in mind, these are the steps.

Host:

1. Install docker and ssh client
2. Add your user to docker group
3. Install VSCode
4. Configure Server
5. (After server config below): edit ~/.config/Code/User/settings.json with

"docker.host":"tcp://localhost:23750",

6. Configure your ssh keys for the Server
7. (After every reboot run on terminal: ssh -N -L localhost:23750:/var/run/docker.sock <user>@<serveraddr>)
8. Run VSCode and install Remote Development extension. Restart VSCode
9. Now you should see your running containers in VSCode Remote explorer > Containers > Other Containers

Server:

1. Install docker and ssh server
2. Install VSCode (this may not be a requirement on the server)
3. Add your user to docker group and start your container
