GitHub SSH public key missing from test-ibm-rhel8_arm_cross_container-x64-1

Related to #3678, as I redeployed all Docker containers on the host.

I disconnected the agent for now.

In https://ci.nodejs.org/job/node-cross-compile/configure there's some scripting that's supposed to add to the known_hosts:

grep -q ^$TEMP_REPO_SERVER ~/.ssh/known_hosts || (ssh-keyscan -t rsa $TEMP_REPO_SERVER >> ~/.ssh/known_hosts)

but looking at, e.g. https://ci.nodejs.org/job/node-cross-compile/nodes=cross-compiler-rhel8-armv7-gcc-10-glibc-2.28/47396/console, the attempt to git checkout is happening before that script is run.

I've manually added the key to the known_hosts file -- we're going to have to update it again when we migrate the tmp binary git repository from Equinix Metal (#3597).

Done the same for test-digitalocean-rhel8_arm_cross_container-x64-2.

Do you know why it's not added by Ansible?

[richardlau]

No. I'm +1 for adding the known_host via Ansible to the machines that need to access the temporary binary git repo.

Hit this after I wiped and re-Ansibled the containers on the x64 Docker hosts.
e.g. https://ci.nodejs.org/job/node-cross-compile/52659/nodes=cross-compiler-rhel9-armv7-gcc-12-glibc-2.28/console

I've opened #4051 to add the entry to known_hosts. After running the updated docker-host playbook, https://ci.nodejs.org/job/node-cross-compile/52660/ (still running) has got past where it failed before.
