[Editor’s note: This post was written by Haoxiang Zhou who was a work placement student at Jetstack for the past four months. We are grateful to Haoxiang for adding this very useful feature, and all his other contributions, and wish him all the best with his final year of study.]

This post will explore the newest addition to the kubectl plugin of cert-manager, kubectl cert-manager status certificate, a command designed to make the troubleshooting experience of cert-manager problems easier.

On behalf of the cert-manager team, it is with great pleasure to announce the v1 release of the cert-manager project!

Configuring MySQL SSL/TLS authentication with cert-manager

We recently worked on a customer project, where they wanted to secure the connection between their Java Spring Boot application and their MySQL Database, all this running on Google Kubernetes Engine (GKE). We suggested they use cert-manager, our preferred certificate management tool on Kubernetes.

Using Kubectl's new Kustomize support for per-environment deployment of cert-manager resources

Introduction Kustomize is an increasingly popular tool for generating Kubernetes manifests, and is now included with Kubectl 1.14. Rather than using templates Kustomize works by applying modifications to already valid manifests. Using this pattern, it provides various features including resource namespacing, modification of metadata, and generation of Kubernetes Secrets. To start using Kustomize you need one or more Kubernetes manifests and a kustomization.yaml file. The kustomization.yaml file is itself a manifest, which specifies a list of resources, patches to apply, and various other options.

Cert-manager reaches v0.6

We’re excited to announce v0.6 of cert-manager, the general purpose X.509 certificate management tool for Kubernetes. Cert-manager provides automated issuance, renewal and management of certificates within your organisation.

Certificate management in highly dynamic environments is no easy feat, and if approached without careful consideration could quickly lead to outages and service interuption when certificates begin expiring. By standardising on a single tool for managing your PKI assets, you can ensure that certificates are being automatically renewed, and that the appropriate teams are notified if there are any issues or policy violations within your cluster.

Cert-manager: native x509 certificate management for Kubernetes

Those of you who closely follow Jetstack’s open source projects may have already noticed that our new certificate management tool, cert-manager, has been available for some time now. In fact, we now have over 1,000 stars on GitHub!

Cert-manager is a general purpose x509 certificate management tool for Kubernetes. In today’s modern web, securing application traffic is critical. cert-manager aims to simplify management, issuance and renewal of certificates within your organisation.
