Let's sort out the issues you're facing with Helm 3 and cover the general workflow for checking chart versions and installing specific releases.

Why Your Commands Failed #

Helm 3 made breaking changes to the search command compared to Helm 2—those -r and -l flags no longer exist, and you need to explicitly target repository searches with helm search repo. Also, helm show all flink failed because you hadn't added the official Flink Helm repository yet.

Corrected Commands for Flink #

1. First, add the official Flink Helm repository (required before searching/showing)

   helm repo add flink https://flink.apache.org/charts
   helm repo update
   

2. Search for Flink chart and list all available versions
   Replace your old helm search -r "*flink*" and helm search -l flink with:

   helm search repo flink --versions
   

   This will output all Flink chart versions hosted in the added repository.
3. Show full details for a Flink chart (specific version optional)
   To get all info for the latest version:

   helm show all flink/flink
   

   For a specific version (e.g., 1.17.0):

   helm show all flink/flink --version 1.17.0
   

General Workflow for Any Helm Chart #

Checking Chart Versions

• Step 1: Add the repository (if not already added)
  If you don't know the repo URL, you can find it in the chart's official docs. For example, for Bitnami charts:

  helm repo add bitnami https://charts.bitnami.com/bitnami
  helm repo update
  

• Step 2: Search the chart and list versions

  helm search repo <chart-name> --versions
  

  Tip: If multiple repos have the same chart name, prefix the chart with the repo name (e.g., bitnami/nginx) to avoid ambiguity.
• Step 3: View detailed info for a specific version

  helm show all <repo-name>/<chart-name> --version <version-number>
  

Installing a Specific Chart Version

Use the --version flag with helm install to target a specific release:

helm install <your-release-name> <repo-name>/<chart-name> --version <version-number>

Example: Installing version 1.25.3 of Bitnami's Nginx chart:

helm install my-nginx bitnami/nginx --version 1.25.3
