git-clone: Auto accept Host-Key

[ReptoxX]

When trying to clone a git-repository through ssh it always fails because it's host-key is not confirmed / not trusted.
I would like to add the host-key before cloning so the git clone command would not fail. Or alternatively just auto-accept the hostkey.

to auto accept the ssh key, you could make a script in the template that runs
ssh-keyscan github.com >> ~/.ssh/known_hosts

this does open you up to man in the middle attacks, where someone pretends to be github.com, and they get automatically trusted.
if you want to ensure that doesnt happen,
run just ssh-keyscan github.com from a trusted environment that you know has no attacker trying to mitm you,
and copy the lines that dont start with #, and in your template, include a script like the following:

echo "github.com ssh-rsa AAAAB3NzaC1yc2......" >> ~/.ssh/known_hosts
echo "github.com ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlz......" >> ~/.ssh/known_hosts
echo "github.com ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAA....." >> ~/.ssh/known_hosts

(this preloads the trusted hostkeys for github, so it's not guessing at startup)

@moo-im-a-cow How do I run the script before git-clone module runs?
