要約

When launching a container for Confluence using Podman, Collaborative Editing doesn't work. Instead, when creating a new page, we are presented to a endless spinning wheel.
The container was launched using the following command line:

podman run -d --name <container_name> -p 8090:8090 -p 8091:8091 -v <data_volume>:/var/atlassian/application-data/confluence <image>

環境

Confluence Server or Data Center 7.1.0+

Podman

診断

In the application logs we can see the following error messages:

atlassian-confluence.log

java.lang.NoClassDefFoundError: Could not initialize class com.sun.jna.platform.linux.LibC$Sysinfo

原因

This behavior is related to the Bug CONFSERVER-59815 - Getting issue details... STATUS and also described in the KB article Synchrony startup fails with "Failed to get mem_unit from sysinfo" error.

In this particular case, we are using a Podman container to launch Confluence. However, by default, Podman always mount volumes with noexec permission, as described in https://github.com/containers/podman/issues/4318

ソリューション

Modify the command line that launches the container to add the exec permission over the mounted volume - as for example:

podman run -d --name <container_name> -p 8090:8090 -p 8091:8091 -v <data_volume>:/var/atlassian/application-data/confluence:exec <image>
