In a previous post, we talked about how we can check our Docker images for any known vulnerabilities by means of Anchore Engine. This still required a manual action. Wouldn’t it be great if we could incorporate Anchore Engine into our Jenkins CI build job or pipeline? In this post, we will take a look at how we can accomplish this by means of the Anchore Container Image Scanner Jenkins Plugin.

When using Docker containers in production, we need to ensure that we are following best practices. In this post, we will focus on Ensure images are scanned and rebuilt to include security patches from the CIS Docker Community Benchmark which we discussed previously. The item states that you should scan your images “frequently” for any vulnerabilities and then take the necessary actions to mitigate these vulnerabilities. We will use Anchore Engine in order to accomplish this.

You are using Docker for development and testing purposes but did not yet take the step to use it in production? Then read on, because in this blog post we will take a look at how you can ensure that you run your Docker containers in a secure way.
Assume a new developer or test engineer is added to your team. You develop an application with obviously some kind of database and you want them to get up to speed as soon as possible. You could ask them to install the application and database themselves or you could support them with it, but this would cause a lot of effort. What if you handed them over a simple YAML file which would get them up to speed in a few minutes? In this post we will explore some of the capabilities of Docker Compose in order to accomplish this.
In part 1 of this post we explained how we can create a Helm Chart for our application and how to package it. In part 2 we will cover how to install the Helm package to a Kubernetes cluster, how to upgrade our Helm Chart and how to rollback our Helm Chart.

In this post we will explain how we can use Helm for installing our application. In part 1 we will take a look how we can create a Helm Chart for our application and how to package it. In part 2 we will cover how to install the Helm package to a Kubernetes cluster, how to upgrade our Helm Chart and how to rollback our Helm Chart.

In this post we will take a closer look at Helm: a package manager for Kubernetes. We will take a look at the terminology used, install the Helm Client and Server, deploy an existing packaged application and take a look at some useful Helm commands.
This week, we will take a look at Red Hat Container Development Kit (CDK). CDK provides a pre-built Container Development Environment based on Red Hat Enterprise Linux to help you develop container-based applications quickly. We will install CDK on a Windows machine and deploy our mykubernetesplanet Docker image from our last post to the Kubernetes cluster.
In part 1 of this post, we learned how to create a Spring Boot application, create a Docker image for it and push it to a Docker registry. At the end, we installed Minikube in an Ubuntu VM. In this second part, we will get familiar with some Kubernetes terminology, deploy the application to our Minikube cluster and update the application. The sources used for the application can be found at GitHub. The Docker registry which we use can be found here (or you can use your own Docker registry).

In this post we will take a look how we can build a Spring Boot application, create the Docker image, deploy it to a Docker registry and deploy it to a Kubernetes cluster. This will give us the opportunity to get acquainted with the basics from building an application up to deploying it to Kubernetes. Sources can be found at GitHub.
