Show the version for Helm.
|
|
|
|
This will print a representation the version of Helm.
|
|
The output will look something like this:
|
|
|
|
version.BuildInfo{Version:"v3.2.1", GitCommit:"fe51cd1e31e6a202cba7dead9552a6d418ded79a", GitTreeState:"clean", GoVersion:"go1.13.10"}
|
|
|
|
- Version is the semantic version of the release.
|
|
- GitCommit is the SHA for the commit that this version was built from.
|
|
- GitTreeState is "clean" if there are no local code changes when this binary was
|
|
built, and "dirty" if the binary was built from locally modified code.
|
|
- GoVersion is the version of Go that was used to compile Helm.
|
|
|
|
When using the --template flag the following properties are available to use in
|
|
the template:
|
|
|
|
- .Version contains the semantic version of Helm
|
|
- .GitCommit is the git commit
|
|
- .GitTreeState is the state of the git tree when Helm was built
|
|
- .GoVersion contains the version of Go that Helm was compiled with
|
|
|
|
For example, --template='Version: {{.Version}}' outputs 'Version: v3.2.1'.
