Get it to work with pm2 about ssh-agent HOT 6 CLOSED

My guess would be that there is no benefit of having this in this central action. I've added a note at https://github.com/webfactory/ssh-agent/blob/master/README.md#run-ssh-keyscan-to-add-host-keys-for-additional-hosts.

I don't know about pm2. Does that SSH into another machine? Does Host key verification failed. happen there?

from ssh-agent.

Yes it does SSH into the machine the app should be deployed on. The error happens there

from ssh-agent.

Then you need to find a way how to provision your known_hosts key there. I am afraid this action cannot do this for you.

Ok, thanks for taking the time. I'll try over at pm2 repo to find some answers.

Ok I figured something out. After disabling strict host checking in my pm2 ecosytem file I got this output:

[PM2] Spawning PM2 daemon with pm2_home=/home/runner/.pm2
[PM2] PM2 Successfully daemonized
--> Deploying to production environment
--> on host MY.SERVER
fatal: HEAD does not point to a branch
  ○ deploying origin/master
  ○ executing pre-deploy-local
  ○ hook pre-deploy
Warning: Permanently added '[MY.SERVER]:36077,[45.10.26.70]:36077' (ECDSA) to the list of known hosts.

So it seems the problem was that host that I wanted deploy to (MY.SERVER) was not in the list of known_hosts on the GH build instance.
Is that something this action could also take care of? Like it does with adding the private key to the ssh-agent?

The script could do ssh-keyscan -t rsa MY.SERVER | ssh-keygen -lf - to add the server to known_hosts file.
