Kubernetes helm error: UPGRADE FAILED: „{RELEASE-NAME}“ has no deployed releases

Sometimes after a failed or canceled Kubernetes helm release `install` or `upgrade` a repetition failes with the following error message

Kubernetes helm error: UPGRADE FAILED: "{RELEASE-NAME}" has no deployed releases

In this case you can either delete and purge your installed release, but be aware that this will also delete the complete history of the release.

Or, the better way, you can repeat your `install` or `upgrade` command with `–force`.

$ helm upgrade {RELEASE-NAME} --install .
Kubernetes helm error: UPGRADE FAILED: "{RELEASE-NAME}" has no deployed releases
...
$ helm upgrade {RELEASE-NAME} --install --force .

Kubernetes helm: Incompatible client:server versions Max OS X)

If running a `helm` command is returning an ‚incompatible versions‘ error like the following, you can either upgrade the server version or downgrade the client version.

Error: incompatible versions client[v2.13.1] server[v2.11.0]

I decided to install several client versions and switch on demand, because upgrading the server version was not an option for me. In addition, having multiple client versions is more flexible in dealing with multiple kubernetes cluster having different versions.

Install the matching `kubernetes-helm` version manually via `brew`:

  1. Search on Github for the kubernetes-helm.rb file for the required version (2.11.0 in my case): https://github.com/Homebrew/homebrew-core/search?q=kubernetes-helm&type=Commits
  2. Click the commit hash (ee94af7 in my case)
  3. Click the „View“ and then „Raw“ button to copy the raw url.
  4. Install the choosen `kubernetes-helm` version (see commands below)
  5. Switch between your installed versions

$ brew unlink kubernetes-helm
$ brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/ee94af74778e48ae103a9fb080e26a6a2f62d32c/Formula/kubernetes-helm.rb
$ brew info kubernetes-helm
$ brew switch kubernetes-helm 2.11.0
