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……

Create Your First Helm Chart

Introduction For a typical cloud-native application with a 3-tier architecture, the diagram below illustrates how it might be described in terms of Kubernetes objects. In this example, each tier consists of a Deployment and Service object, and may additionally define ConfigMap or Secret objects. Each of these objects are typically defined in separate YAML files, and are fed into the kubectl command line tool. A Helm chart encapsulates each of these YAML definitions, provides a mechanism for configuration at deploy-time and allows you to define metadata and documentation that might be useful when sharing the package. Helm can be useful in different scenarios: Find and use popular software packaged as Kubernetes charts Share your own applications as Kubernetes charts Create reproducible builds of your Kubernetes applications Intelligently manage your Kubernetes object definitions Manage releases of Helm packages Let……
