DESCRIPTION:

This is example on how to create and run Electric Flow Server cluster with Docker Compose.

Diagram:

USAGE:

Run a Electric Flow Server Cluster with Docker Compose:

Gentle reminder: You'll need to first increase your memory of your docker machine to at least 3 GB + n * 3 GB (n=number of commander instances), or you'll have really bad performance due to disk swapping or even not able to start up the cluster.

Step 1: copy license.xml to conf folder

Step 2: Run:

  docker-compose up -d
  docker-compose scale commanderserver=n #replace n to number of instances you want to run
  docker-compose logs -f

You'll run the latest version of Flow Server

Step 3: open http://your.docker.machine.ip:1936/haproxy?stats

Step 4: when you see commander backend is up and running (when the commander servers turns green in haproxy page),

  docker exec $(docker ps |grep commanderserver_1|awk '{print $1}')   /tmp/scripts/import_license_and_create_resource.sh

Step 5: open https://your.docker.machine.ip and login with admin/changeme

Shutdown the cluster

  docker-compose stop

Try other versions

If you want to run a specific version of Flow server version, try:

  export TAG=7.2.0
  docker-compose up -d

Available versions include: 6.0.0, 6.0.6, 7.0.0, 7.0.1, 7.1.0, 7.2.0, latest

Clean up the data which generated when runs the cluster

  make cleandata 

or

  make clean

Save images

TAG=7.2.0 make save

Then images will be saved to your images folder, so you don't need to download again later.

Load images

TAG=7.2.0 make load

This will load your previously saved images to docker

Build your own cluster images

Put the Electric Flow installer to the EC-Dockerfiles folder and run:

  export EFLOW_INSTALLER=ElectricFlow-7.1.0.113861
  export TAG=7.1.0
  make build

This will build several images. Afterwards you can run cluster with those images as described previously.
