Using a Private Registry in Kubernetes

Docker Trusted Registry (DTR) in a Docker Enterprise Edition (EE) cluster allows users to create a private image repository for their own use. They may want to do this when they want to use the cluster for their work but don’t want to or can’t use their own system or they’re not ready yet to share it with others. However, using a private image repository in a Kubernetes deployment requires some additional steps. In this post, I will show you how to setup the repository and use it in your deployment.

Functional Kubernetes Namespaces in Docker Enterprise

For Kubernetes in a Docker Enterprise Edition (EE) 2.1 cluster, namespaces can be used to segregate objects and, with Role Based Access Control (RBAC), designate which users or groups can do what within each of them. In this post, we are going to create three namespaces for development, test and production environments, four groups for the development, test, operations and management teams and access controls defining what each of these groups can do in each of these namespaces.

Create a Kubernetes User Sandbox in Docker Enterprise

When you create a user in Docker Enterprise Edition (EE), that user can immediately create a Swarm service on the cluster. All they need to do is generate, download, unzip and “execute” their client bundle. However, on the Kubernetes side Role Based Access Control (RBAC) and the default user permissions are quite a bit different. I will show you how to get a similar experience with Kubernetes that you get with the out-of-the-box experience of Swarm.
