docker-compose v2 format

Use with docker-compose v1.8 or later only to create stack for orchestrations using docker 1.12 or later.

customize the deployment

edit docker-compose.override.yml to set the URL hostname

build the DAB file

BRANCH=develop INPORT=3020 docker-compose bundle

You can change the INPORT above. You can change the BRANCH between latest and develop.

Note that there will be warning about network key. That is expected.

deploy the stack on your swarm

docker deploy rocketchatdev

Note that the project (stack) name may be different in your case.

This will start the entire stack - mongo, rockechat, and the overlay network.

make the stack available from the hosts

Since host port is non-portable, it is not included in docker-compose build.

Add it to service after deployment:

docker service update -p 3020:3020 rocketchatdev_rocketchat

Again your project (stack) name may be different.
