Initial E2E run ran this PR's test successfully, but failed on another existing test due to it not actually deploying an Ingress. Second run after fixing that: https://github.com/Kong/kubernetes-ingress-controller/actions/runs/2018941298 |
Check Kong's status endpoint and read its config hash during the update loop. If the config hash reported by Kong is the known empty hash, send configuration even our hash is unchanged. This provides configuration to Kong instances that have unexpectedly crashed and lost their configuration.
Add a utility function to kill a Kong container to the E2E helpers. Kill the Kong container at the end of the DB-less E2E test to ensure the controller pushes configuration after it restarts. Fix a bug in verifying Ingresses. Previously the helper continued testing on non-200 responses, and would consider the standard 404 response valid.

What this PR does / why we need it:
Bumps the Kong version to 2.8, the first version that supports this.
Resends configuration when the proxy instance reports its initial, no config present hash.
Adds tests to verify config recovers after a crash. Fixes a bug where we trusted the standard proxy 404 response when verifying Ingresses due to an improperly-bounded if.
