TL;DR: play as long as you can without help, until you get frustrated. At that point, the recommended region order helps a lot without spoiling anything but region names. If you can't find the next region, the world map (only showing region connections, no detail) will tell you what direction to look in.
Within GitHub it is possible to set up two types of SSH key - account level SSH keys and and repository level SSH keys. These repository level SSH keys are known in GitHub as deploy keys.
Deploy keys are useful for deploying code because they do not rely on an individual user account, which is susceptible to change, to “store” the server keys.
There is, however, an ‘issue’ with using deploy keys; each key across all repositories on GitHub must be unique. No one key can be used more than once. This becomes a problem when deploying to repositories to the same server with the same user. If you create two keys, the SSH client will not know which key to use when connecting to GitHub.
One solution is to use an SSH config file to define which key to use in which situation. This isn’t as easy as it seems.. you might try something like this:
Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).
docker run -it --rm --privileged --pid=host justincormack/nsenter1
