Deploy, Scale and rollback an Application with Helm
Introduction Containers have revolutionized application development and delivery on account of their ease of use, portability and consistency. And when it comes to automatically deploying and managing containers in the cloud (public, private or hybrid), one of the most popular options today is Kubernetes. Kubernetes is an open source project designed specifically for container orchestration. Kubernetes offers a number of key features, including multiple storage APIs, container health checks, manual or automatic scaling, rolling upgrades and service discovery. Applications can be installed to a Kubernetes cluster via Helm charts, which provide streamlined package management functions. Assumptions and Prerequisites This guide focuses on deploying an example phpbb application in a Kubernetes cluster running on either Huaweicloud CCE or Minikube. This guide makes the following assumptions: You have a Kubernetes 1.5.0 (or later) cluster. You have kubectl installed and configured to work……
