Subject: [PATCH] Add Helm v2 client initialization using tiller postStart exec
|
||
|
||
This adds helm v2 client initialization using the tiller
|
||
container postStart exec to access helm v2 binary.
|
||
|
||
This will perform 'helm init', removes the default repos
|
||
'stable' and 'local', and add valid repos that were provided
|
||
as overrides. Note that helm will only add repos that exist.
|
||
|
||
This expects overrides in this format:
|
||
conf:
|
||
tiller:
|
||
charts_url: 'http://192.168.204.1:8080/helm_charts'
|
||
repo_names:
|
||
- 'starlingx'
|
||
- 'stx-platform'
|
||
repos:
|
||
stable: https://kubernetes-charts.storage.googleapis.com
|
||
|
||
This gives the following result:
|
||
helmv2-cli -- helm repo list
|
||
NAME URL
|
||
stable https://kubernetes-charts.storage.googleapis.com
|
||
starlingx http://192.168.204.1:8080/helm_charts/starlingx
|
||
stx-platform http://192.168.204.1:8080/helm_charts/stx-platform
