What is Plone?

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

%%LOGO%%

Features

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

Usage

Start a single Plone instance

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

$ docker run -p 8080:8080 %%IMAGE%%

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

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

Start ZEO server in the background

$ docker run --name=zeo %%IMAGE%% zeo

Start 2 Plone clients (also in the background)

$ docker run --link=zeo -e ZEO_ADDRESS=zeo:8080 -p 8081:8080 %%IMAGE%%
$ docker run --link=zeo -e ZEO_ADDRESS=zeo:8080 -p 8082:8080 %%IMAGE%%

Start Plone in debug mode

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

$ docker run -p 8080:8080 %%IMAGE%% fg

Add-ons

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

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

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

  • 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
