We are using argo cd and kubernetes.
And I want to use environmental variables in the yaml file.
For example,
apiVersion: v1
kind: Service
metadata:
name: guestbook-ui
annotations:
spec:
ports:
- port: $PORT
targetPort: $TARGET_PORT
selector:
app: guestbook-uiI want to set the value of the environmental variable (PORT and TARGET_PORT) when deploying it to Argo CD.
What should I do?
I'd recommend converting your raw YAML to a Helm chart and templating the relevant fields.
Argo CD has an example Helm app with a service similar to yours.
You could define a service like this:
apiVersion: v1
kind: Service
metadata:
name: guestbook-ui
annotations:
spec:
ports:
- port: {{ .Values.service.port }}
targetPort: {{ .Values.service.targetPort }}
selector:
app: guestbook-uiAnd then define your port and targetPort parameters in Argo CD.
