Well contained: Running TYPO3 in Docker

TYPO3 CMS Docker

---

For the 10th edition of my book Practical Knowledge in TYPO3 (original title Praxiswissen TYPO3) that is going to be released end of this month, I was looking for a way to offer readers an easy quickstart with TYPO3 - for all operating systems.

Accessing Kubernetes CRDs from the client-go package

Kubernetes Docker Go

---

The Kubernetes API server is easily extendable by Custom Resource Defintions. However, actually accessing these resources from the popular client-go library is a bit more complex and not thoroughly documented. This article contains a short guide on how to access Kubernetes CRDs from your own Go code (UPDATED 2020/04 to adjust to API changes in recent client-go versions, using Go modules and doing (some) code generation with controller-gen).

Surf In The Cloud: TYPO3 Surf-Deployments nach EC2

NEOS CMS TYPO3 Surf AWS

---

After a while, manually deploying my tiny site got a little tedious. As a solution, I decided to automate this deployment using TYPO3 Surf. Since I’m also working with Surf on the job, that task was not too difficult for me. However, the first version of my deployment script did not really “feel” good (you know that feeling when you have built something that works well, but just doesn’t “feel” good, don’t you?):

Not that TYPO3 Neos would not be fast enough on its own, when you figure out how turn on the Production mode. For no other reason than “Because I can” I tried by how much I could speed up this site by using Varnish. I was particularly interested how well TYPO3 Neos and Varnish play together.

Of all the features of TYPO3 Neos, one that astonishes me most is the system’s extensibility. For this site, I needed the possibility to present source code examples with syntax highlighting. Luckily, that isn’t any problem at all in Neos. In this article, I describe how you can extend TYPO3 Neos with a custom NodeType that renders a content element with source code and syntax highlighting into your Neos site.
