The latest News and Information on Containers, Kubernetes, Docker and related technologies.
In the past, applications would be deployed by installation on a host, using the operating system package manager. This was a heavy solution with tremendous reliance on the operating system package manager and increased complexity with libraries, configuration, executables and so on all interconnected. Then came containers. Containers are small and fast, and are isolated from each other and from the host.
In this blog I will show some best practices for instrumenting Docker containers, using docker-compose with a few popular AppDynamics application agent types. The goal here is to avoid rebuilding your application containers in the event of an agent upgrade, or having to hard-code AppDynamics configuration into your container images. In my role as a DevOps engineer working on AppDynamics’ production environments, I use these techniques to simplify our instrumented container deployments.
Kubernetes is an open-source container-orchestration system for automating application deployment, scaling, and management. It was originally designed by Google, and is now maintained by the Cloud Native Computing Foundation.
Security is a key consideration for any organization seeking to standardize and scale their cloud-native platforms. Falco, the behavioral activity monitoring tool from Sysdig, is becoming a popular option for open source container runtime security on cloud-native platforms built using Kubernetes, Cloud Foundry, and OpenShift.
A couple weeks ago, we released the Helm chart and docker images so you could install StackStorm Enterprise HA cluster in Kubernetes. Today, we’re glad to announce that the Community free and open source edition of StackStorm HA is now available, too!
