We are evaluating Confluence deployed to Kubernetes cluster. The pod is deployed just fine and first time configuration page shows up. Here is a few parameters used in k8s deployment:

  • JVM_MINIMUM_MEMORY - 2048m
  • JVM_MAXIMUM_MEMORY - 2048M
  • Persistent volume size - 10G

All else is standard as specified in Atlassian docker hub: https://hub.docker.com/r/atlassian/confluence-server/

 

When we get to choose using the internal built-in database it always error out with a 500:

HTTP Status 500 – Internal Server Error

Type Exception Report

Message Cannot call sendError() after the response has been committed

Description The server encountered an unexpected condition that prevented it from fulfilling the request.

@Edward Yuan , I try to do the same as you by deploying Jira DataCenter on a kubernetes by trying to make it work as it is first.

I have few question based on this :

Q1 : The image is state Data-Center, does it means the image contains all data center configuration or do we have to build the data center and push the image there ?

How did you do ? can you describe your steps?

I am new in kubernetes and have basic knowledge on docker

Thanks for help

regards

Hi Edward,

 

There was an issue with an older version of our Confluence image, where incorrect permissions had been set on $CONFLUENCE_HOME/confluence.cfg.xml (where database configuration is stored).

Would you be able to pull the latest version of the tag you were using, and try again? When we fix an issue we rebuild all of our versions/tags, so even if you're not using the latest version of Confluence, there should be an up-to-date image for the tag you're using that you can pull to try this again.

Let me know how you go!

 

Cheers,

Dave
