helm version and helm env Sanity Checks is a free Helm Academy lesson on CoddyKit — lesson 3 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Helm Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Two Commands to Trust Your Setup
Before installing anything, two commands prove Helm is healthy: helm version tells you the client build, and helm env shows how it is configured.
Reading helm version
Run helm version. It prints the SemVer release, the git commit, and the Go version the binary was built with.
helm versionClient-Only by Design
Notice there is no server version. Helm 3 dropped Tiller, so helm version reports only the client. The cluster part lives in your kubeconfig.
Short Version Output
Want just the number for a script or a quick glance? The --short flag trims the output to a single tidy version string.
helm version --shortVersion as a Template
Helm can format output with Go templates. Use --template to extract exactly the field you need, like the version, for automation.
helm version --template '{{.Version}}'What helm env Reveals
Run helm env to print the environment variables Helm uses: data, cache, and config directories plus the active namespace.
helm envHELM_DATA_HOME
HELM_DATA_HOME is where Helm stores plugins and other state. Knowing this path helps when you install plugins or debug a broken setup.
HELM_CONFIG_HOME and Repos
HELM_CONFIG_HOME holds your repository list and registry config. This is the file that remembers every repo you have added.
HELM_CACHE_HOME
HELM_CACHE_HOME caches downloaded chart indexes and archives. Clearing it forces Helm to refetch, which can fix stale-index problems.
Overriding the Defaults
Each path is just an env var. Export HELM_NAMESPACE or the home vars to relocate config, handy for isolated CI runs or multiple profiles.
export HELM_NAMESPACE=my-appUse env in Scripts
Because helm env prints clean KEY=value lines, you can eval its output or grep one variable to drive automation reliably.
helm env | grep HELM_NAMESPACEQuick Check
Someone asks why helm version shows no server build.
Recap
helm version confirms the client build and that Tiller is gone, while helm env shows the data, config, and cache paths Helm relies on. 🔍
