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...
