NOTE: Our images are excellent for test driving Plone, checking add-ons or as a base for development/theming.
We don't recommended them for production!

Plone

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

Features

• Images for Plone 5.x and Plone 4.x
• Images for Plone 6 are available at https://github.com/plone/plone-backend
• Enable add-ons via environment variables
• Built-in RelStorage support, configurable via environment variables (requires Plone 5.2+)
• Built-in LDAP/AD support via pas.plugins.ldap (requires Plone 5.1+)

NOTE: Python 2 based Docker images are no longer supported by the Docker Official Images
If you need Python 2, you can use plone/plone:5-python2 instead of plone:5-python2.

Supported tags and respective Dockerfile links

• 5.2.13-python38, 5.2-python38, 5-python38, python38, 5.2.13, 5.2, 5, latest (5.2.13/Dockerfile)

Older versions

• 5.2.13-python2, 5.2-python2, 5-python2, python2 (5.2.13/python2/Dockerfile)
• 5.1.6, 5.1 (5.1.6/Dockerfile)
• 4.3.19, 4.3, 4 (4.3.19/Dockerfile)

Prerequisites

Make sure you have Docker installed and running for your platform. You can download Docker from https://www.docker.com.

Usage

Choose either single Plone instance or ZEO cluster.

NOTE: 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), standard container linking will make it automatically available to the linked containers.

You can add a Plone Site at http://localhost:8080 - default Zope user and password are admin/admin.

By using the tags listed above a Plone container with a different version can be downloaded and started.

The following command starts a Plone 4.3 container, based on Alpine.

docker run -p 8080:8080 plone:4.3-alpine

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 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.
• SITE - Add Plone with this id to Data.fs on first run. If NOT provided, you'll have to manually add a Plone Site via web UI
• VERSIONS - Use specific versions of Plone Add-on or python libraries

Run Plone and install two addons (eea.facetednavigation and collective.easyform).

docker run -p 8080:8080 -e SITE="mysite" -e ADDONS="eea.facetednavigation collective.easyform" plone

To use specific add-ons versions:

 -e ADDONS="eea.facetednavigation collective.easyform" -e VERSIONS="eea.facetednavigation=13.3 collective.easyform=2.1.0"

RestAPI:

docker run -p 8080:8080 -e SITE=plone plone

curl -H 'Accept: application/json' http://localhost:8080/plone

For advanced usage

Plone:

• PLONE_ADDONS, ADDONS - Customize Plone via Plone add-ons using this environment variable
• PLONE_SITE, SITE - Add Plone with this id to Data.fs on first run. If NOT provided, you'll have to manually add a Plone Site via web UI
• PLONE_VERSIONS, VERSIONS - Use specific versions of Plone Add-on or python libraries
• PLONE_PROFILES, PROFILES - GenericSetup profiles to include when SITE environment provided.
• PLONE_ZCML, ZCML - Include custom Plone add-ons ZCML files
• PLONE_DEVELOP, DEVELOP - Develop new or existing Plone add-ons
• BUILDOUT_EXTENDS - Add configuration files that buildout should extend
• FIND_LINKS - Add custom find-links to the buildout configuration
• SOURCES - Add custom sources to the buildout configuration

To add custom sources, the SOURCES env var needs to be a string containing a comma-separated list of sources. This is different from the other environment variables described above, which are space-separated.

For example:

 -e SOURCES="plone.restapi = git https://github.com/plone/plone.restapi,plone.staticresources = git https://github.com/plone/plone.staticresources"

ZEO:

• ZEO_ADDRESS - This environment variable allows you to run Plone image as a ZEO client.
• ZEO_READ_ONLY - Run Plone as a read-only ZEO client. Defaults to off.
• ZEO_CLIENT_READ_ONLY_FALLBACK - A flag indicating whether a read-only remote storage should be acceptable as a fallback when no writable storages are available. Defaults to false.
• ZEO_SHARED_BLOB_DIR - Set this to on if the ZEO server and the instance have access to the same directory. Defaults to off.
• ZEO_STORAGE - Set the storage number of the ZEO storage. Defaults to 1.
• ZEO_CLIENT_CACHE_SIZE - Set the size of the ZEO client cache. Defaults to 128MB.
• ZEO_PACK_KEEP_OLD - Can be set to false to disable the creation of *.fs.old files before the pack is run. Defaults to true.

CORS:

• CORS_ALLOW_ORIGIN - Origins that are allowed access to the resource. Either a comma separated list of origins, for example http://example.net,http://mydomain.com or *. Defaults to http://localhost:3000,http://127.0.0.1:3000
• CORS_ALLOW_METHODS - A comma separated list of HTTP method names that are allowed by this CORS policy, for example DELETE,GET,OPTIONS,PATCH,POST,PUT. Defaults to DELETE,GET,OPTIONS,PATCH,POST,PUT
• CORS_ALLOW_CREDENTIALS - Indicates whether the resource supports user credentials in the request. Defaults to true
• CORS_EXPOSE_HEADERS - A comma separated list of response headers clients can access, for example Content-Length,X-My-Header. Defaults to Content-Length,X-My-Header
• CORS_ALLOW_HEADERS - A comma separated list of request headers allowed to be sent by the client, for example X-My-Header. Defaults to Accept,Authorization,Content-Type,X-Custom-Header
• CORS_MAX_AGE - Indicates how long the results of a preflight request can be cached. Defaults to 3600

RELSTORAGE:

• RELSTORAGE_ADAPTER_OPTIONS - A comma separated list of RelStorage adapter options to set for the plone instance (using plone.recipe.zope2instance). This is required in order to use RelStorage.
