I want to deploy nextcloud with helm and a custom value.yaml file that fits my needs. Do i have to specify all values given from the original value.yaml or is it possible to only change the values needed, Eg if the only thing I want to change is the host adress my file can look like this:
nextlcoud:
host: 192.168.178.10instead of copying this file and changing only a few values.
you misspelled the nextcloud to nextlcoud in your value file.
As the underlying issue was resolved by the answer of user @Kun Li, I wanted to add some examples when customizing Helm charts as well as some additional reference.
As asked in the question:
Do i have to specify all values given from the original value.yaml or is it possible to only change the values needed
In short you don't need to specify all of the values. You can change only some of them (like the host from your question).
The ways to change the values are following:
- Individual parameters passed with
--set(such ashelm install --set foo=bar ./mychart)- A values file if passed into
helm installorhelm upgradewith the-fflag (helm install -f myvals.yaml ./mychart)- If this is a subchart, the
values.yamlfile of a parent chart- The
values.yamlfile in the chart
You can read more about it by following official Helm documentation:
A side note!
Above points are set in the order of priority. The first one (
--set) will have the highest priority to override the values.
A side note!
This examples assume that you are in the directory of a pulled Helm chart and you are using Helm v3
Using the nextcloud Helm chart used in the question you can set the nextcloud.host value by:
new-values.yaml to pass it in (the values.yaml from Helm chart will be used regardless with lower priority): $ helm install NAME . -f new-values.yamlnew-values.yaml
nextcloud:
host: 192.168.0.2helm install NAME . --set nextcloud.host=192.168.0.2You can check if the changes were done correctly by either:
$ helm template . - as pointed by user @David Maze$ helm install NAME . --dry-run --debug
