Crashing containers following official docker-compose getting started guide

[jpittis]

Summary

Hey folks. I'm encountering crashing containers while following the official docker-compose guide getting started guide:

$ mkdir mantis
$ cd mantis
$ wget https://raw.githubusercontent.com/Netflix/mantis/master/docker-compose.yml
$ docker-compose -f docker-compose.yml up

I can see logs showing that mantisagent, mantismaster, and mantisapi all exit with non-zero status codes (in that order):

mantis-compose-mantisagent-1 exited with code 2
mantis-compose-mantismaster-1 exited with code 1
mantis-compose-mantisapi-1 exited with code 1

I'm running this on OSX Sonoma (aarch64), but have been able to reproduce on Linux (amd64) as well.

Details

Right before the crash of the agent and the master, I see the following log line from ZooKeeper:

mantis-compose-zookeeper-1         | 2023-12-13 01:40:04,582 [myid:] - WARN  [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:ZooKeeperServer@675] - Received packet at server of unknown type 19

Other potential culprit logs (there are too many to dump all of them here) include:

mantis-compose-mantisagent-1       | 2023-12-13 01:40:03 ERROR AgentV2Main:114 - Unexpected error: java.lang.IllegalStateException: Expected the service TaskExecutorStarter [FAILED] to be RUNNING, but the service has FAILED

After encountering this thread, I decided to try bumping the ZooKeeper version to something more recent (specifically "jplock/zookeeper:3.5.5"), and that seems to have resolved the issue. I'll be following up with a PR to bump the docker-compose file, at which point I believe we can close this issue.

Hello, we have moved to using Helm for running containers. You can follow the README in this repo:

https://github.com/Netflix/mantis-helm

It should start all the necessary containers in Kubernetes.

Sweet, thanks for sharing the preferred approach @calvin681.

Does that imply we don't want the docker-compose file fixed?

In that case, should we delete it and update the getting started guide to point to mantis-helm instead?

[jpittis]

@calvin681: Separately, is there a chance that my issues building from source (https://github.com/Netflix/mantis/issues/604) are related to the fact that developers build using some special process/env that's also out of date with the official docs?

[calvin681]

Yes, we should delete docker compose and update the docs.

We still use gradle to build, see this line in our github action: https://github.com/Netflix/mantis/blob/master/.github/workflows/nebula-ci.yml#L39

If that's failing, then it's likely a bug.

How about we keep this ticket open until we fix up the docs. I should have an opportunity to go through the helm process later this week, and it shouldn't be that much extra work to fix up the docs at the same time.
