We're working on an upgrade from v19.7 to v21.3. For the upgrade, I've restored postgres and config backups into a whole new environment. * Ran the db-migrator and upgraded from old to new db schema * Purged some nodes from the cruise-config.xml (to get rid of all elastic configs, including all elastic and non-elastic agents), and changed other values to prevent conflict with "prod" instance. * Installed latest "release" version (7.0.0-4) of the ECS Elastic Plugin and configured a new cluster
I then unpaused a single pipeline and assigned it the Elastic profile. The task gets created in ECS and I can see it running on the EC2 instance. This is where the trouble starts. At this point, the agent tries to "auto-register" with the server and is rejected 2021-11-09 02:23:30,499 ERROR [qtp1711838422-42] AgentRegistrationController:242 - Rejecting request for registration. Error: HttpCode=[422] Message=[Elastic agent registration requires an auto-register agent key to be setup on the server.

I've switched it over to new GUIDs several times (with and without dashes) and every time I get the same message logged on the server and a similar message on the elastic agent: 2021-11-09 02:24:25,694 ERROR [scheduler-1] SslInfrastructureService:173 - Error occurred during agent registration process: Elastic agent registration requires an auto-register agent key to be setup on the server.

Agent-id: [GoCD64cbbd28b581471386946cc75bc03ad2], Plugin-id: [com.thoughtworks.gocd.elastic-agent.ecs] There is an NGINX reverse proxy that sits in front of the server and is configured according to https://docs.gocd.org/21.3.0/installation/configure-reverse-proxy.html#agents-and-reverse-proxies. The way it seems to me is that the agentAutoRegisterKey="89a52addc1b241c0be4c81e9fd2068cb key inside the server node in the XML is not being parsed properly as the server is unaware of this key having been set. On a side note, I came across from discussions and (merged) PRs about using ephemeral EA autoregister keys, but wasn't able to find much in the way of documentation. Is this "ephemeral" autoregistration process implemented? Is the process documented anywhere? -- You received this message because you are subscribed to the Google Groups "go-cd" group.
