This command lists all of the releases for a specified namespace (uses current namespace context if namespace not specified).
|
|
|
|
By default, it lists only releases that are deployed or failed. Flags like
|
|
'--uninstalled' and '--all' will alter this behavior. Such flags can be combined:
|
|
'--uninstalled --failed'.
|
|
|
|
By default, items are sorted alphabetically. Use the '-d' flag to sort by
|
|
release date.
|
|
|
|
If the --filter flag is provided, it will be treated as a filter. Filters are
|
|
regular expressions (Perl compatible) that are applied to the list of releases.
|
|
Only items that match the filter will be returned.
|
|
|
|
$ helm list --filter 'ara[a-z]+'

|
|
|
|
If no results are found, 'helm list' will exit 0, but with no output (or in
|
|
the case of no '-q' flag, only headers).
|
|
|
|
By default, up to 256 items may be returned. To limit this, use the '--max' flag.
|
|
Setting '--max' to 0 will not return all results. Rather, it will return the
|
|
server's default, which may be much higher than 256. Pairing the '--max'
|
|
flag with the '--offset' flag allows you to page through results.
