In this post I demonstrate a simple container deployment setup; a Jenkins pipeline to Elastic Container Registry (ECR) and Fargate on Elastic Container Service (ECS). I assume you have Jenkins running, with a pipeline and Git repo webhook tied to it. Besides the default Jenkins plugins, you’ll need the Pipeline Utiliy Steps. Also I assume you already have a ECR repository, a ECS Fargate cluster and an AWS service account with credentials. I decided not to use the AWS credentials plugin since it is too implicit. So instead, set regular username & password: ...

With any project, personal or for clients, I develop and build applications in Docker containers; so it would be really convenient to run these as containers in production. Usually I’ll spin up a small Ubuntu VM (GCP/Azure/AWS/Digital Ocean) and install Docker manually. I would love to run everything with Kubernetes as a container orchestrator, but the costs of such a cluster for personal usage seems rather high. Until I found this article by Remko Seelig, using Kubernetes on Google Cloud with preemptible nodes, which is about half the price of regular instances. You loose some availability but that’s probably no problem in my case. ...

I was happy with Helm when a far-more-experienced-Kubernetes-guy told me I should not use Helm because Tiller is unsafe and some other reasons. Now I follow the method of Tobias Bradtke, with the advantage of declarative application management; while I keep one cluster-definition in one Git repository. update: The most apparent change of Helm 3 is the removal of Tiller, which makes the templating as shown here less relevant When you want to route HTTP and HTTPS traffic from outside your Kubernetes cluster to services inside your cluster, this can be done with Nginx-Ingress. Let’s Encrypt is a non-profit certificate authority run by Internet Security Research Group to provide free TLS certificates and cert-manager is a Kubernetes addon to automate the management and issuance of TLS certificates from various issuing sources. ...

For a project I was specifically asked to build an API using Python Django. So, my first starting point was to google “django cookiecutter” which immediately brought me to this amazing cookiecutter project. What I am going to demonstrate here is how to quickly setup the project (for the sake of completeness) and use Gitlab Continuous Integration to automatically unit test, run linters, generate documentation, build a container and release it. ...
