Secure Kubernetes certificates with cert-manager and Dekorate

Secure Kubernetes certificates with cert-manager and Dekorate by Jose Carvajal Hilario, Anna-Maria Mihalceanu, and Charles Moulliard.

Managing SSL certificates for your cloud native apps can sometimes get a little tricky. Cert-manager, a popular tool for cloud-native certificate management helps makes this task a lot easier. But before they can start using it, developers need to deal with creating custom resources that cert-manager requires. Enter Dekorate, the tool that significantly decreases the complexity of managing custom resource for Kubernetes and OpenShift. This walkthrough demonstrates how Dekorate automatically creates cert-manager custom resources from annotations in your code. You can then install these resources in a project on your cluster and use them to secure the REST endpoints of your application with TLS. The article provides rich code examples for every step, and also an example application project based on Spring Boot that you can use to follow along with the walkthrough.

How to use Java Mission Control to monitor Java apps

How to use Java Mission Control to monitor Java apps by Francesco Marchioni

Those of you with an interest in monitoring the performance of your Java apps will find Francesco’s post especially informative. The article focuses on Java Flight Recorder (JFR), a JVM monitoring tool that also powers the recently released Cryostat project. In addition to offering insights into the JFR user experience compared to competing tools like JConosle and VisualVM (which he covered in earlier articles), Francesco also provides a quickstart guide for spinning up JFR with Java Mission Control to monitor a Wildfly server.

SaaS security in Kubernetes environments: A layered approach

SaaS security in Kubernetes environments: A layered approach by Alex Kubacki

In his most recent article, Alex Kubacki analyzes recommended practices for securing software-as-a-service applications. Opening with the argument that if you want to truly secure your applications, you must secure every layer of your application stack (all the way from the hardware to the container network interface), Alex moves on to break down the security concerns specific to each layer. He gives particular attention to the cluster and networking layers, where he highlights the benefits of recently released projects, including Advanced Cluster Security for Kubernetes and the more recent networking security innovations in OpenShift.
