# Checks a host that deploy/bootstrap.sh just installed (or re-ran on). The e2e workflow
|
|
# runs it on a fresh GitHub runner after each of its two installer runs:
|
|
#
|
|
# sudo bash deploy/e2e_check.sh install # after the first run
|
|
# sudo bash deploy/e2e_check.sh rerun # after the same commit ran again

# sudo bash deploy/e2e_check.sh release # after the newest release installed
|
|
# sudo bash deploy/e2e_check.sh upgrade # after this commit ran over a release
|
|

|
# It asks what an operator's first minutes ask: the binary runs, the control plane is
|
|
# rolled out and ready, the panel answers on its NodePort, the proxy answers a Minecraft
|
|
# status ping, and the host timers are there. A rerun must also leave the proxy running
|
|
# (it restarts only when what it runs changed) and keep every earlier answer.
