Jira and Confluence Docker images allow the use of environment variables to overwrite properties in server.xml, such as ATL_TOMCAT_MAXHTTPHEADERSIZE.

This functionality is not available in the Bamboo Docker image. This feature request proposes adding support for such environment variable to enhance configuration flexibility and consistency across Atlassian products. This would allow users to easily adjust server settings without modifying the server.xml.j2 file directly and rebuilding the image, streamlining the deployment process in containerized environments.

Workaround

1. In the Bamboo Docker image replace the contents of maxHttpHeaderSize in /opt/atlassian/etc/server.xml.j2 with:

   maxHttpHeaderSize="{{ atl_tomcat_maxhttpheadersize | default('8192')}}"
   

2. Start the container as usual declaring an environment variable ATL_TOMCAT_MAXHTTPHEADERSIZE with the value you require.
