Docker EE (Engine, UCP and DTR)

Stop! Look at scripts for tools to automatically create a Swarm mode cluster, a UCP cluster, or a DDC (both UCP & DTR) cluster. You can even start a preconfigured Jenkins to use for demos. If you want to manually stand up an engine or Swarm mode cluster, read on.

Image Tags

For a complete list of published images, see the list of tags on Docker Hub. For each major release, the specific Docker EE bugfix versions are also available and can be found via Docker Hub. If you always want to use the latest of a given platform release, stick with the 17.06-ee (or the like image for that platform release) image.

Build images (optional)

The images are published to Docker Hub so you do not need to build them unless you want to,

Note: your <DOCKER-EE-URL> value can be found from

  • Docker for Mac installed
  • Must have the following ports available on your host:
    • 1000 - TCP connection to a single Docker engine (or whatever you specify)
    • 1001, 1002, 1003 - TCP connection to Docker engines for Swarm mode (or whatever you specify)

Single engine

  1. Start engine

     docker run -d \
       --name docker \
       --privileged \
       -p \
       -v /lib/modules:/lib/modules:ro \
       -v docker:/var/lib/docker \
       -v docker-etc:/etc/docker \
       --tmpfs /run \
       mbentley/docker-in-docker \
       dockerd -s overlay2 -H unix:///var/run/docker.sock -H tcp://
  2. Communicate with that engine

     docker -H tcp://localhost:1000 info
  3. Check version

     docker -H tcp://localhost:1000 version
  4. Destroy the Engine

     docker kill docker
     docker rm docker
     docker volume rm docker

Swarm mode cluster

  1. Create 3 engines

     for ENGINE_NUM in {1..3}
       docker run -d \
         --name docker${ENGINE_NUM} \
         --privileged \
         -p${ENGINE_NUM}:2375 \
         -v /lib/modules:/lib/modules:ro \
         -v docker${ENGINE_NUM}:/var/lib/docker \
         -v docker${ENGINE_NUM}-etc:/etc/docker \
         --tmpfs /run \
         mbentley/docker-in-docker \
         dockerd -s overlay2 -H unix:///var/run/docker.sock -H tcp://
  2. Create a new Swarm

     docker -H tcp://localhost:1001 swarm init
  3. Get the worker join token and command

     TOKEN=$(docker -H tcp://localhost:1001 swarm join-token worker -q)
     JOIN_COMMAND="swarm join --token ${TOKEN} $(docker container inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' docker1):2377"
  4. Join engine 2

     docker -H tcp://localhost:1002 ${JOIN_COMMAND}
  5. Join engine 3

     docker -H tcp://localhost:1003 ${JOIN_COMMAND}
  6. Check status

     docker -H tcp://localhost:1001 node ls
  7. Destroy Swarm cluster

     docker kill docker1 docker2 docker3
     docker rm docker1 docker2 docker3
     docker volume rm docker1 docker2 docker3
