Docker Swarm + Traefik for developers

With this cluster you can deploy in your localhost or your cloud server a Docker Swarm to develop or you can test a Docker-based ecosystem of applications for you. It is not recommended to use for production environments.

Requirements

Knowledges: docker, docker-compose, swarm, DNS
To have installed docker previously

Installation

We have to join in a cluster mode with next command in your machine:

docker swarm init

OPTIONAL: If you have more than 1 node, click here

Clone repository and choose protocol: http or https, in this example we will use https

git clone https://github.com/agosalvez/easy-devops.git

Local:

cd easy-devops/swarm/http

Cloud server:

cd easy-devops/swarm/https

Edit for Let's Encrypt (only https mode)

traefik.yml:14 => Set your own email for letsencrypt

Deploy cluster

Next script will create a pair of docker networks and deploy the traefik and portainer stacks:

Windows

./win/initCluster.bat

Unix

./unix/initCluster.sh

Local

/etc/hosts

Modify portainer.yml:31 with your desired domain (your own domain if you are in a server)

# Add the following line (or your domain) to the end of the /etc/hosts file:
127.0.0.1   portainer.mylab.com

The domain have to be exactly in hosts file and portainer.yml:31

Cloud server

Redirect you desired domain to your server public IP and configure right labels in portainer.yml:31

Usage

Local

Go to http://portainer.mylab.com

Cloud server

Go to https://portainer.mylab.com (or your domain setted in portainer.yml) to try it!

Bonus extra

After that, you can start and stop this cluster with these scripts:

Start cluster

Windows

./win/startCluster.bat

Unix

./unix/startCluster.sh

Stop cluster

Windows

./win/stopCluster.bat

Unix

./unix/stopCluster.sh
