Run in Docker

The Connect2id server is now also available as a Docker image for easy container-based setup and evaluation.

1. Installing Docker

If Docker isn’t already installed on your computer you can find instructions here. The Community Edition (CE) is sufficient to run a Connect2id server.

2. Content of the Docker image

The provided Docker image includes the required Java runtime and an exploded copy of the ZIP package we make available for download – a Tomcat servlet container with a Connect2id server WAR, an OpenID relying party client and a few other sample WARs deployed in it. A relational database (H2 in embedded mode) for the Connect2id server to persist its own data is also included.

3. Configuring the Connect2id server

The Connect2id server configuration is located in a set of properties files in the /WEB-INF/ directory of its web application archive (WAR).

Any of those properties can be overridden by injecting a text file with the new properties into the Docker container at /etc/c2id/override.properties. The injection can be done by means of a volume, bind mount or a custom storage driver. The steps below use the bind mount method.

4. To run in a container

Important: The currently provided Docker image uses host networking, which has no isolation between host and container and is limited to Linux hosts.

The basic steps to run the Connect2id server in a Docker container:

1. Pull the latest image from Docker Hub

   The available versions are listed in the c2id Docker repository.

   docker pull c2id/c2id-server:[version]

2. (Optional) Save your custom properties in a override.properties file

   For example:

   op.issuer                   = https://my.idp.com
   op.authz.endpoint           = https://my.idp.com/login
   op.authz.apiAccessToken     = vuxiehaiGhohrahJeik0ui0aib9jai9c
   op.reg.apiAccessToken       = Oosoje7choh1dom8ahng4kueQuoo6la0
   op.logout.apiAccessToken    = eik1Oosahpaic5dei2ioco4og9rahkee
   authzStore.apiAccessToken   = Ahrek9shie3Eidaex9lu4biem7ahpeeb
   sessionStore.apiAccessToken = foo7ahM5koo9eiziah7ahwaequaek5ta
   monitor.apiAccessToken      = caew6jaeX2phah8oolaoghaec0Heer8l
   jose.jwkSet                 = eyAia2V5cyIgOiBbIHsgImt0eSIgOi...
   

3. Run a container with the image

   Replace host_port with an available port on your host.

   • Without a custom override.properties file:

     docker run -p host_port:8080 --network host c2id/c2id-server:[version]

   • With a custom override.properties injected via bind mount:

     docker run -p host_port:8080 --mount type=bind,source="/directory/containing/override/file",target=/etc/c2id c2id/c2id-server:[version]

For extra options that may be of use see the Docker run command reference.
