In the last post I showed how you can build a Docker image in a Kubernetes cluster using with Forgejo runner. One missing step was the actual deployment of the new Docker image.

Ansible: Combine group and host vars

Mon, 25 Oct 2021 08:13:01 +0200

In Ansible the configuration parameters are usually separated into two categories: host and group vars. As their names say these are variables that are either applied to a specific host or a group of hosts. And here is already an edge case. What if we want to configure a variable for group, but then also give the possibility to modify for a specific host. Read on to see my solution.

Manage Vercel DNS records with Ansible

Thu, 11 Feb 2021 11:41:16 +0100

At Mint System we are using Ansible extensively to configure our infrastructure and services. From setting up new hosts up to deploying a customer specific customization for an application, all is managed by Ansible. Only one piece was missing. Until recently we could not update DNS records automatically.

Build multiple Docker image from Yarn workspace packages

Fri, 13 Dec 2019 18:17:28 +0100

If you decide to manage your node application repository as a monorepo you sure heard about Yarn workspaces. Yarn has an out-of-the-box support for managing multiple packages in a single codebase. Using yarn workspaces package dependencies can be centralized and packages can reference each other. Tasks can be executed for all packages at once. It solves various build related problems for a monorepo.

This post was first published at Abilium - Blog.

Recently, we decided to setup a new monitoring service. We opted for the ELK stack. The ELK stack constists of three products:

Setup GoCD environment using docker

Tue, 06 Nov 2018 12:11:01 +0200

At AdNovum we are running GoCD for automating the continuous delivery (CD) of our software products. GoCD has become the de facto standard for running CD pipelines.

In this post I will give you a short introduction into GoCD using docker. We are going to setup a GoCD environment consisting of a server, an agent and deployable material. Further we are going to configure a deployment pipeline and build an node.js application.

Profiling Ansible roles and tasks

Wed, 07 Mar 2018 13:11:25 +0000

Performance is critical when deploying an environment with Ansible. By default Ansible does not tell how much time elapsed for specific role or task. However, this information would be critical to identify inefficient tasks. Luckily Ansible offers an interface for callback plugins. With the help of a callback plugin one can hook into the role or task execution call. In this post I’ll show you how to configure the callback plugins for profiling roles and tasks. It is quite easy.

Working with Ansible - Cleanup tasks

Mon, 26 Feb 2018 11:30:13 +0000

My current project is heavily based on Ansible. We use Ansible to deploy into different environments and domains. The configuration has become quite complex. That is why we need to cleanup a server from time to time. Especially when one has to upgrade services on a server and requires to get rid of the old services first. In this post I would like to show you, how we define and run Ansible cleanup tasks in our project.

Vagrant - portable development environment

Tue, 02 Jul 2013 11:54:35 +0000

Today almost every coder uses git or another vcs and a related service like github for code hosting.

As a front end designer twitters bower is the right tool to manage your libary dependencies.

And for the backend developer the npm package manager is always on board.

Those tools have changed the way of developing websites and webapplication.

They’ve increased productivity and the flexibilty for your application.

So far, there’s only one part lagging behind: It’s the development environment.
