There are many solutions for performing log collection or log management. Personally I’ve got experience with using the ELK stack. So this post will focus on ELK with Logspout for log collection.
Here’s how to upgrade Docker in a Swarm mode cluster without cluster down time.
I recently started playing around with Terraform. Since I often manually spin up a couple of droplets on DigitalOcean to set up a Swarm mode cluster to try out some projects or set ups, I figured I should put all of that into code as my first Terraform project. I created a Terraform module for provisioning a basic Swarm mode cluster during this project. Ideal for labs or development clusters.
