Okterakt Verlag is an independent publisher based in Germany and focused on practical cloud-native security publishing. Two books have been published so far: Docker & Kubernetes Security and Black Forest Shadow.
Black Forest Shadow is published under an Okterakt Verlag ISBN. The first edition of Docker & Kubernetes Security was released with an Amazon-assigned ISBN, while a future Okterakt edition is planned for broader bookstore distribution. A Git-focused title may follow next. Made in Germany, with a slight bias toward containers.
The site is intentionally compact: Okterakt Verlag acts as the publisher-facing home, while DockerSecurity.io remains the broader hub for articles, workshops, direct purchases, and supplementary learning material.
