I have a few services running on a kubernetes cluster, and I use Helm Chart where I placed all my services. However, I was asked to transfer Helm Charts into Helmfile. If I use
helmfile import myrepo/mychart
helmfile sync
Will it redeploy and substitute existing running pods or It will deploy just deploy additional services mentioned
Helm uses a packaging format called charts. A chart is a collection of files that describe a related set of Kubernetes resources. A single chart might be used to deploy something simple, like a memcached pod, or something complex, like a full web app stack with HTTP servers, databases, caches, and so on.
Helmfile is a declarative spec for deploying helm charts. It lets you... Keep a directory of chart value files and maintain changes in version control. Apply CI/CD to configuration changes. Periodically sync to avoid skew in environments.
To avoid upgrades for each iteration of helm, the helmfile executable delegates to helm - as a result, helm must be installed.
Like @DavidMaze suggested, use helm diff command first to determine the changes and then use helm sync command for applying them.
