Docker files

file	use
docker-compose.yml	Run the full app in a single machine. For dev (run in your machine) and tests
docker-compose-stack.yml	Run the app in arqss swarm

Dev deploy

Use docker-compose to deploy the full app in a single machine for testing

docker-compose build    # Build images
docker-compose up -d    # Run them

Swarm deploy

Use docker stack deploy to deploy the app in a docker swarm manager node

# Initialize swarm in a node
docker swarm init
# Use provided command to join
# other nodes into swarm

# Create network for the stack
docker network create --driver overlay proxy
# Deploy the stack
docker stack deploy -c docker-compose-stack.yml arqui

To unmount the stack and the swarm

docker stack rm arqui
docker network rm proxy
docker swarm leave --force

Update service

If a new version of a service image is available we can update it

docker service update --image <image> <service>

This will update one service task at a time, reducing downtime
Number of services updated in parallel is defined in the stack file
