Ming Wait.Charts are self-contained logical units that apply deployments.You can think of chart s as software installation packages in apt, yum

Helm is an official YUM-like package manager and a process encapsulation for deployment environments.Helm has two important concepts: chart and releaseĬhart is a collection of information that creates an application, including configuration templates, parameter definitions, dependencies, documentation for various Kubernetes objects Single file (deployment.yaml, service.yaml).Then call Kubectl to automate K8s resource deployment Helm is essentially to make K8s'application management (Deployment,Service, etc.) configurable and dynamically generated.Dynamically generate K8s resource cleanup Helm supports release version management and control by packaging, which greatly simplifies the deployment and management of Kubernetes applications One: What is Helm Before using helm, deploying applications to kubernetes requires a cumbersome process of deployment, svc, and so on.Moreover, as many projects are microserviced, deployment and management of complex applications in containers becomes more complex.
