Docker Swarm autodeploy

This script automatically deploys a Docker Swarm cluster on our infra.

Once this is done, you can create docker services. In other words you can take your docker-compose.yml and "transform" it into a persistent service.

TLDR

ssh deploy@10.33.0.11

# Get information about services...
sudo docker stack ls
sudo docker service ls # See all the services running on the cluster...

git clone https://my_awesome_service
cd my_awesome_service

sudo docker-compose build
sudo docker-compose push
sudo docker stack deploy NAME_OF_YOUR_SERVICE --compose-file docker-compose.yml

I want to deploy a new service / I want to update a service!

Tasks:

Build the service
Push the service to our registry
Deploy the service

Building and pushing the service...

In order for the containers to be available to all of the VM running Docker, you must specify a registry server of the cluster in your docker-swarm.yml.

The registry will store the built version of your containers.

First, if you build some custom containers in your dockerfile, for instance:

version: '3'
services:
  api:
    build: ./api
    environment:
      MY_ENV_VAR: 5000
[...]

Add a "image:" directive for each build:.

version: '3'
services:
  api:
    build: ./api
    image: localhost:5000/rootme_api_python
    environment:
      MY_ENV_VAR: 5000
[...]

Then you will build your service.

SSH on docker1:

ssh deploy@10.33.0.11

# Transfer your project on the VM... (you can use git, wget, scp...)
git clone https://my_awesome_service
cd my_awesome_service

1/ Build your service

sudo docker-compose build

2/ Push your service on the registry

sudo docker-compose push

3/ Deploy your service

sudo docker stack deploy NAME_OF_YOUR_SERVICE --compose-file docker-compose.yml
sudo docker stack ls
sudo docker service ls # See all the services running on the cluster...
