GKE Autopilot + Elastic Cloud

Community Support Server Deployment

Hi everyone!
I was able to deploy temporal server to GKE Autopilot and it looks like it works but for some reason if I set ENABLE_ES=“true” it works opposite way I cannot see any workflows nor in Temporal or even ES index itself but if I will set ENABLE_ES=“false” it works as expected. I can see my workflows info in Temporal UI and I can see data in index too.

                  key: elastic.password

Here is my config.
Unfortunately, I wasn’t able to use helm chart but I do believe I set my settings correctly.

The question is why ES integration works only with ‘ENABLE_ES=false’ do I miss something?

The question is why ES integration works only with ‘ENABLE_ES=false’ do I miss something?

Here is the default docker template from which your server config is created (for all service roles since you are using auto-setup image). You can also bash into your pod and see parsed config at /etc/temporal/config/docker.yaml.

Where is ES deployed? My guess is some issue with setup/connecting to ES (check ES_SEEDS and if you need to set up username/password).
Here is the auto-setup script that sets up ES indexes if that helps.
If you disable ENABLE_ES temporal still creates the temporal_visibility db which seems to work fine in your case (so you use standard and not advanced visibility).

Thank you man! You helped a lot. The problem was with this parameter:

- name: ES_VERSION
  value: "v8"

Apparently, you do not have a separate index_template for the ElasticSearch version 8. I changed to “v7” and it works now!
