Tool to automate Docker Swarm

I have followed the Docker Docs about setting up Swarm on Virtualbox. I suppose it is the same procedure to set it up on AWS, Azure or DigitalOcean. It is a lot to do manually every time .

Is there a tool to automate this?

I would like to use something to set up and scale Swarm like Compose does for Docker .

Maybe I would start with one AWS instance and 2-3 containers and then scale them up to 100 containers and the instances to scale accordingly. Then I would want to scale down to 2 instances and the rest would shut down.

Does something like this exist ?

Solution

  • You can use Ansible for configuring the Swarm master, Swarm nodes, and all the required cluster discovery. Ansible is a general IT automation tool, but it comes with a very powerful Docker module that allows to set up Docker Swarm easily.

    This GitHub repository shows a good example how to set up Swarm with Ansible.
