Adding arrays as Kubernetes environment variables
You can inject your entire application.conf with a mechanism of ConfigMaps:
apiVersion: v1
kind: ConfigMap
metatada:
name: app-config
data:
application.conf: |
play.cache.redis {
# enable cluster mode
source: cluster
# nodes are defined as a sequence of objects:
cluster: [
{
# required string, defining a host the node is running on
host: localhost
# required integer, defining a port the node is running on
port: 6379
# optional string, defines a password to use
password: null
}
]
}
and then mount it directly to your container:
apiVersion: v1
kind: Pod
metadata:
name: ....
spec:
containers:
- name: ...
image: ...
volumeMounts:
- name: config-volume
mountPath: /etc/config
volumes:
- name: config-volume
configMap:
name: app-config
The app can access it then at /etc/config/application.conf.
