Use: "fetch",
|
|
Short: "Fetch charts from state file",
|
|
Long: `Fetch downloads all charts referenced in the Helmfile state.
|
|
|
|
Useful for air-gapped environments: download charts with --output-dir and --write-output,
|
|
then transfer the output directory and the generated helmfile.yaml to the air-gapped environment.
|
|
|
|
The --write-output flag requires a single helmfile state file specified with -f.
|
|
It fails if the input resolves to multiple state files (e.g. a directory or a helmfile
|
|
with nested helmfiles: entries).`,
