History prints historical revisions for a given release.
|
|
|
|
A default maximum of 256 revisions will be returned. Setting '--max'
|
|
configures the maximum length of the revision list returned.
|
|
|
|
The historical release set is printed as a formatted table, e.g:
|
|
|
|
$ helm history angry-bird --max=4
