Quick reference

What is Plone?

Plone is a free and open source content management system built on top of the Zope application server.


  • Images for Plone 5 and Plone 4
  • Enable add-ons via environment variables


Start a single Plone instance

This will download and start the latest Plone 5 container, based on Debian.

$ docker run -p 8080:8080 plone

This image includes EXPOSE 8080 (the Plone port), so standard container linking will make it automatically available to the linked containers. Now you can add a Plone Site at http://localhost:8080 – default Zope user and password are admin/admin.

Start Plone within a ZEO cluster

Start ZEO server

$ docker run --name=zeo plone zeoserver

Start 2 Plone clients

$ docker run --link=zeo -e ZEO_ADDRESS=zeo:8100 -p 8081:8080 plone
$ docker run --link=zeo -e ZEO_ADDRESS=zeo:8100 -p 8082:8080 plone

Start Plone in debug mode

You can also start Plone in debug mode (fg) by running

$ docker run -p 8080:8080 plone fg


You can enable Plone add-ons via the PLONE_ADDONS environment variable

$ docker run -p 8080:8080 -e PLONE_ADDONS="eea.facetednavigation Products.PloneFormGen" plone

For more information on how to extend this image with your own custom settings, adding more add-ons, building it or mounting volumes, please refer to our documentation.
