IBM Build Labs helps IBM partners to scale their businesses and to reach new markets. (more…)

Over the last two Corona years I have spent some time with home improvements on weekends. A lot of fun! (more…)

Many IBM partners want to understand how to scale their offerings to reach new markets. Technically this often translates to two technologies: Kubernetes Operators and SaaS (Software as a Service). As I'm working with IBM partners, my team has created several assets for our co-creation engagements. (more…)

The real power or Kubernetes operators are not day 1 tasks like the initial deployments, but the automation of day 2 operations. This article describes a sample operator that scales up an application automatically based on the number of API requests. (more…)

Operators automate day 2 operations for Kubernetes based software. Operators need to know the state of their operands. One way to find out the state is to check metrics information stored in Prometheus. This article describes how to export metrics from applications running on Kubernetes to make them accessible by Prometheus. (more…)

Operators are a powerful technology to automate operations of software in Kubernetes clusters. This article describes scenarios when operators should be used and which value they provide. (more…)

When developing auto-pilot capabilities in Kubernetes operators, often CronJobs and Jobs are used to automate operations. This article describes how to implement such jobs with Golang. (more…)

Kubernetes operators allow the automation of day 2 operational tasks. A good example is the automatic archiving of data. This article describes how data from a simple database can be archived automatically in S3 buckets using CronJobs, Jobs and custom resources. (more…)

While there are plenty of examples how to write stateless applications on Kubernetes, there are relative few simple samples explaining how to write stateful applications. This article describes how to write a simple database system with Quarkus. (more…)

Kubernetes supports running stateless and stateful workloads. This article describes the core concepts how to build and run a simple database on Kubernetes using an open source sample. (more…)
