Summary

In the case of automated deployments that is Chef, Ansible, etc., or containers like Docker or Kubernetes most of the settings are passed to the Bitbucket java process with the help of environmental variables.

It is important to control if the values are passed correctly to the process.

Environment

Any supported version with automated deployment or containers.

Diagnosis

You can see which environmental variables and Java properties are passed to the Bitbucket process under Administration (Support) → Troubleshooting and support tools → System Information (Sections Java Runtime Environment and Environment variables)

If the list of the variables and properties differs from the one you configured and verified on the OS level (Docker describe container, kubectl describe pod etc.) then there is an issue with the syntaxis of one of the variables you set.

Check the startup logs for the syntax errors:

/opt/atlassian/bitbucket/bin/_exec-webapp.sh: eval: line 60: syntax error near unexpected token {{(' 
/opt/atlassian/bitbucket/bin/_exec-webapp.sh: eval: line 60: }}echo Dcluster.node.name=bitbucket-test2 -Dintegration.jira.key.pattern=([A-Z][A-Z0-9]\d)'

Cause

Syntax errors or missing double quotes in value can cause the process to disregard further variable settings.

For example following declaration in Docker has missing double quotes for Dintegration.jira.key.pattern

      JVM_SUPPORT_RECOMMENDED_ARGS: >-
        -Dcluster.node.name={{ inventory_hostname }}@{{ ansible_hostname }}
        -Dintegration.jira.key.pattern={{ '([A-Z][A-Z0-9]+-\d+)' }}

Solution

Check the syntax and fix the typos or add quotes for the string values and restart the instance (container).
