How to upload a plugin Jar file in Confluence Datacenter cluster ?

Question

Due to the changes in latest versions and different company policies, I am looking for an option to update or install an Add-on for confluence instances, which are running on Datacenter cluster from backend server.

I see that for Jira DC cluster, we have a shared home directory where we can upload the plugin, but for confluence shared home- I don't see any plugins folder and it is very hard to identify whether we need to keep the file in Plugin-Cache folder or not.

Early response should be much appreciated.

Thank you in advance,

The plugins have to be installed into the confluence/WEB-INF/atlassian-bundled-plugins/ directory for confluence data center.

The downside of this is that any plugins installed this way show up as system plugins and not user installed plugins.

Note that my testing of preinstalling questions for confluence against 8.5.16 LTS version also resulted in an error for the plugin. It would not enable after the node came online or when manually clicking the enable button from the UPM. Removing it from the list of plugins I am pre-installing and redeploying the node brought questions for confluence back to functioning state.

The solution for installing plugin from the backend server on confluence data center cluster setup is to place plugin jar file on each node separately.

Thanks @Benjamin for your quick response, I can enable it but I am more interested in understanding the confluence cluster setup. I see few plugins at one place and other few are not even in the shared home plugin folder. That's where my concern arises.
