Set Up / Installation

Docker Swarm Usage

Set up 3 nodes in a swarm

SSH into manager node and install docker-compose on manager:

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

Create temporary image registery:

docker service create --name registry --publish published=5000,target=5000 registry:2

Build the custom images:

docker-compose -f docker-compose-swarm.yml build

Push custom app images to registery:

docker-compose -f docker-compose-swarm.yml push

Create network:

docker network create --scope=swarm --driver=overlay   --subnet=172.22.0.0/16 --gateway=172.22.0.1 app-network

Deploy:

docker stack deploy --compose-file docker-compose-swarm.yml workrosterapp

Initalising swarm On manager node:
docker swarm init --advertise-addr $(hostname -i)
On worker nodes:
docker swarm join --token [token from above command] [external IP]:2377

Exiting swarm

docker stack rm workrosterapp
docker service rm registry
docker network rm app-network
docker swarm leave --force

Docker-compose Usage

Building images

cd Work-Roster-App
docker-compose build
