Docker zu CRIO-O

Switching from Docker to CRI-O

In this blog post, we’d like to answer some FAQs regarding the change from Docker to CRI-O. Here we go!
Kafka and Ansible

Automating Kafka with Ansible

In all areas of life, there are a lot of issues we are not aware of. To measure these problems, we use the so-called fulfillment rate. For example: with a fulfillment rate of 90%, a heart beat would stop every 85 seconds, and an average A4 page of text would contain 30 typos. A fulfillment rate of 99.9% (which seems a lot) still means 22,000 wrong bank bookings per hour, and a total of 32,000 missed heart beats per year. The answer is automation and standardization! These approaches help solve problems we are often not aware of.

Container Technologie beim IT-DLZ

Container Technology at IT-DLZ

At OSAD 2021, Matthias Kanzog from IT-DLZ Bayern gave an insight into the container technology used. "In order to be able to deploy applications faster and more flexibly in the future while ensuring data security, the IT DLZ decided to set up its own container operation." This is Matthias' answer to the "crucial question" about agility and flexibility in public authorities.

Docker Alternatives

Docker has started a revolution with its easy access to Linux containers: Containerized applications, microservices, DevOps, GitOps, and Kubernetes are noticeably spreading. But then suddenly it says "Docker support in [kubernetes] is now deprecated and will be removed in a future release”. What does this mean for you and your work with containers? With Kubernetes? For starters, the good news is that you don't have to change much at all. This blog briefly outlines existing alternatives, categorizes them, and provides a brief example for developers.

Docker Swarm: A herd of containers

0 Comments
Welcome to Docker Swarm! Containers thrive like pack animals in large numbers, but their distribution on the servers is crucial. Docker Swarm, which has been integrated into the Docker Engine since version 1.12, is ideal for this. Learn more about manager and worker nodes, service variants, load balancing and scalability. This is part 3 of our Docker/Rancher series, in which we look at the distributed environment of Docker Swarm.
