This command installs and updates charts defined in Armada manifest.
|
|
|
|
The apply argument must be relative path to Armada Manifest. Executing apply
|
|
command once will install all charts defined in manifest. Re-executing apply
|
|
command will execute upgrade.
|
|
|
|
To see how to create an Armada manifest:
|
|
https://airship-armada.readthedocs.io/en/latest/operations/
|
|
|
|
To install or upgrade charts, run:
|
|
|
|
\b
|
|
$ armada apply examples/simple.yaml
|
|
|
|
To override a specific value in a Manifest, run:
|
|
|
|
\b
|
|
$ armada apply examples/simple.yaml \
|
|
--set manifest:simple-armada:release="wordpress"
|
|
|
|
Or to override several values in a Manifest, reference a values.yaml-formatted
|
|
file:
|
|
|
|
\b
|
|
$ armada apply examples/simple.yaml \
