What is Plone?

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

Features

• Enable add-ons via environment variables. • Choose between Debian or Alpine based images. • Built-in RelStorage support, configurable via environment variables (requires Plone 5.2.4+). • Built-in LDAP/AD support via pas.plugins.ldap (requires Plone 5.2.4+).

Usage

Start a single Plone instance

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

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. The default Zope user and password are admin/admin.

Start Plone within a ZEO cluster

A ZEO cluster is best suited for production setups. You will need a load balancer.

Start ZEO server in the background.

Start two Plone clients, also in the background.

Start Plone in debug mode

You can also start Plone in debug mode (fg) by running the following command.

Add-ons

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

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 the Plone 5 documentation.

Supported environment variables

The Plone image uses several environment variables.

Basic usage

• ADDONS - Customize Plone via Plone add-ons using this environment variable. • SITE - Add a Plone instance with this ID to Data.fs on first run. If not provided, you'll have to manually add a Plone site via the web UI. • ZEO_ADDRESS - This environment variable allows you to run the Plone image as a ZEO client. • VERSIONS - Use specific versions of Plone add-on or Python libraries.

Run Plone and install two add-ons (eea.facetednavigation and collective.easyform).

To use specific add-on versions, change the environment variable arguments as shown.

To use Plone REST API, start the Plone Docker image, then issue a command to curl.
