I have a particular need. I'd like to add a go template to the environment values, but have them interpreted in releases.values.
Here's a simplified example:
helmfile.yaml
releases:
- name: cluster
chart: ../charts/cluster
values:
- values/cluster/values.yaml.gotmpl
environments:
development:
values:
- ./environments/development/values.yaml.gotmpl
values/cluster/values.yaml.gotmpl
registry:
docker:
url: '{{ .Values | get "registry.docker.url" "" }}'
service-1:
enabled: {{ .Values | get "service-1.enabled" false }}
chartValues:
{{ toYaml .Values.service-1.chartValues | indent 4 }}
service-2:
enabled: {{ .Values | get "service-2.enabled" false }}
chartValues:
{{ toYaml .Values.service-2.chartValues | indent 4 }}
environments/development/values.yaml.gotmpl
registry:
docker:
url: "registry.hub.docker.com"
service-1:
enabled: true
chartValues:
image:
repository: {{ .Values | getOrNil "registry.docker.url" }}/service-1
service-2:
enabled: true
chartValues:
image:
repository: {{ .Values | getOrNil "registry.docker.url" }}/service-2
In reality there are many services with different chartValues for each service.
The problem with this example is that it interprets registry.docker.url too early (the values are null at the environment level). I'd like them to be dynamically filled when they arrive at releases.values. I think I need to use tpl but I haven't succeeded.
thanks for your support
Move releases and environments to separate files and include them in helmfile.yaml with bases keyword and yaml doc separator like this:
bases:
- environments.yaml
---
bases:
- releases.yaml
That should do the work, just be assure to not use hyphens in values key names (or use index method)
I personally use such approach in my deploy repos (example)
