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


  • Images for Plone 5.x and Plone 4.x
  • Enable add-ons via environment variables
  • Choose between Debian or Alpine based images

Supported tags and respective Dockerfile links


Make sure you have Docker installed and running for your platform. You can download Docker from


Choose either single Plone instance or ZEO cluster.

It is inadvisable to use following configurations for production.

Standalone Plone Instance

Plone standalone instances are best suited for testing Plone and development.

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.

Plone As ZEO Cluster

ZEO cluster are best suited for production setups, you will need a loadbalancer.

Start ZEO server in the background

$ docker run -d --name=zeo plone zeo

Start 2 Plone clients (also in the background)

$ docker run -d --name=instance1 --link=zeo -e ZEO_ADDRESS=zeo:8080 -p 8081:8080 plone
$ docker run -d --name=instance2 --link=zeo -e ZEO_ADDRESS=zeo:8080 -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

Debug mode may also be used with ZEO

$ docker run --link=zeo -e ZEO_ADDRESS=zeo:8080 -p 8080:8080 plone fg

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.

Supported Environment Variables

The Plone image uses several environment variable that allow to specify a more specific setup.

For Basic Usage

  • ADDONS - Customize Plone via Plone add-ons using this environment variable
  • ZEO_ADDRESS - This environment variable allows you to run Plone image as a ZEO client.

Run Plone with ZEO and install two addons (PloneFormGen and collective.roster)

$ docker run --name=instance1 --link=zeo -e ZEO_ADDRESS=zeo:8080 -p 8080:8080 \
-e ADDONS="Products.PloneFormGen collective.roster" plone

To use specific add-ons versions:

 -e ADDONS="Products.PloneFormGen==1.8.5 collective.roster==2.3.1"
