Optimised Docker builds for Rails apps
In this post I’ll share some tips on how to make Docker builds for Rails apps faster and more efficient.
Highly available, external load balancer for Kubernetes in Hetzner Cloud using haproxy and keepalived
Hetzner Cloud doesn’t offer a load balancer service yet, so I had to set up an external load balancer. Here’s how to do it.
Postgres on Kubernetes with the Zalando operator
In this post I’ll show how to install the Zalando operator for Postgres, how to create a cluster and how to perform backups and restores.
Secure Kubernetes on Hetzner Cloud with a node driver for Rancher
In this post, we’ll see how to deploy Kubernetes to Hetzner Cloud using a node driver for Rancher. By default, when using this node driver Rancher doesn’t set up any firewall, leaving etcd exposed. Here’s how to fix that while still taking advantage of the convenience of the node driver.
Linstor storage for Kubernetes, the Kubernetes way
An update on how to set up Linstor storage for Kubernetes, this time in a more cloud native way.
Getting the user’s real IP with haproxy ingress behind Cloudflare
When using haproxy ingress behind Cloudflare, the IPs in the access logs are Cloudflare’s instead of the actual IPs of the users. In this post, I’ll show how easily fix that.
Rails and Active Storage: permanent URLs with no redirects, using Digital Ocean behind Cloudflare
In this post I’ll show how to easily use Digital Ocean S3 compatible storage for Active Storage while taking advantage of Cloudflare’s free bandwidth; I’ll also show how to ensure that links to attachments are non-expiring and are direct links to the CDN without the default redirect mechanism.
Provisioning, backing up and restoring a highly available Rancher cluster with Terraform
In the previous post, we’ve seen how to automate the complete deployment of a Kubernetes cluster with Rancher using Terraform and Ansible. In this post, we’ll see how to automate the creation of a HA cluster for Rancher itself.
From zero to Kubernetes in Hetzner Cloud with Terraform, Ansible and Rancher
In this post, I am sharing how I set up cheap Kubernetes clusters in Hetzner Cloud using an amazing combinations of powerful tools.
Using Drone CI/CD to build, test your images and deploy to Kubernetes with Helm
Drone is a very lightweight and simple, but powerful CI/CD solution that is designed for containers. In this post, we’ll see how to implement a pipeline from build to deployment to Kubernetes.
