Server

Install Nuxeo with the Docker Image

Updated: May 21, 2021

Preamble

This page explains how to install the Nuxeo server with the base Nuxeo Docker image. Yet, to build an application from Nuxeo, most of the time, you will need to customize this image and build your own. For this purpose, we strongly recommend to use an immutable image by building a custom Docker image from the Nuxeo one.

Configuring the Image at Runtime

Though we encourage to have immutable images configured at build time, in some cases it makes sense to configure a container at runtime. This typically applies to the address and credentials of each back-end store (database, Elasticsearch, S3, etc.) that are specific to a given deployment: development, staging, production, etc.

Configuration Properties

To add or update some configuration properties when running a container from a Nuxeo image, please read the related section about nuxeo.conf.

Environment Variables

Currently, these are the environment variables that are taken into account by a Nuxeo image:

  • JAVA_OPTS
  • NUXEO_CLID
  • NUXEO_CONNECT_URL
  • NUXEO_PACKAGES

JAVA_OPTS

Please first have a look at the default JVM settings in the Nuxeo Docker image.

The value of JAVA_OPTS is appended to the JAVA_OPTS property defined in nuxeo.conf at startup.

For instance, to make the Nuxeo Launcher display the JVM settings in the console, run:

docker run --name nuxeo \
  -p 8080:8080 \
  -e JAVA_OPTS=-XshowSettings:vm \
  docker-private.packages.nuxeo.com/nuxeo/nuxeo:2021

NUXEO_CLID

The value of NUXEO_CLID is copied to /var/lib/nuxeo/instance.clid at startup. Please check the Registering your Nuxeo Instance documentation page to create a valid CLID.

For instance, to run a container with a registered Nuxeo instance:

docker run --name nuxeo \
  -p 8080:8080 \
  -e NUXEO_CLID=<NUXEO_CLID> \
  docker-private.packages.nuxeo.com/nuxeo/nuxeo:2021

NUXEO_CONNECT_URL

NUXEO_CONNECT_URL allows to override the default Connect URL at startup.

For instance, to run a container with another Connect URL than the default one:

docker run --name nuxeo \
  -p 8080:8080 \
  -e NUXEO_CONNECT_URL=<NUXEO_CONNECT_URL> \
  nuxeo:LTS-2019

NUXEO_PACKAGES

NUXEO_PACKAGES allows to define a space separated list of Nuxeo packages to install at startup.

For instance, to run a container with the nuxeo-web-ui and nuxeo-drive packages installed:

docker run --name nuxeo \
  -p 8080:8080 \
  -e NUXEO_CLID=<NUXEO_CLID> \
  -e NUXEO_PACKAGES="nuxeo-web-ui nuxeo-drive" \
  nuxeo:LTS-2019

NUXEO_DEV

Setting NUXEO_DEV=true allows to run the Nuxeo image in development mode, meaning:

  1. Enable the following configuration properties, see the Configuration Parameters Index (nuxeo.conf) page for more details:

    org.nuxeo.dev=true
    org.nuxeo.rest.stack.enable=true
    # for hot reload
    nuxeo.server.sdk=true
    nuxeo.server.sdkInstallReloadTimer=true
    
  2. Override the default command executed when running a container, allowing to execute some nuxeoctl commands inside the container without killing it. This way, you can for instance:

    • Copy some JAR files to the nxserver/bundles directory of the server and restart it with nuxeoctl restart:

      docker run --name nuxeo \
      -p 8080:8080 \
      -e NUXEO_DEV=true \
      nuxeo:LTS-2019
      
      docker ps
      CONTAINER ID   IMAGE
      0eee2751d09d   nuxeo:LTS-2019
      
      docker exec 0eee2751d09d nuxeoctl restart
      
    • Register your instance with nuxeoctl register.

    • Use hot reload with the Nuxeo Dev Tools Extension.
    • Use hot reload with Nuxeo CLI.
  3. Activate debugging for the nuxeoctl mp-install command run when installing Nuxeo packages with NUXEO_PACKAGES.

Shell Scripts

To run some shell scripts when starting a container from a Nuxeo image, you can add *.sh files in the /docker-entrypoint-initnuxeo.d directory of the image.

They will be alphabetically sorted and executed at the very end of the ENTRYPOINT, after handling the environment variables. Thus, if you run a container by passing the NUXEO_CLID environment variable, invoking nuxeoctl in such a shell script will work as being registered.
