To get one of our issue resolved, we need "CATALINA_OPTS=-Djava.awt.headless=true" this property in Kubernetes configuration. i guess this should be added in .yml file.
Please help us , under which this has to be added. Thanks in advance.
Any sample Yaml file or link to it if provided will be great.
It could go as ConfigMap
As an example, if you want to have the variable CATALINA_OPTS, to contain the value "-Djava.awt.headless=true", you can do this:
apiVersion: v1
kind: ConfigMap
metadata:
name: my-config
data:
CATALINA_OPTS: "-Djava.awt.headless=true"
---
apiVersion: v1
kind: Pod
metadata:
name: my-pod
spec:
containers:
- name: bb
image: k8s.gcr.io/busybox
command: [ "/bin/sh", "-c", "env" ]
envFrom:
- configMapRef:
name: my-config
restartPolicy: Never
# kubectl logs my-pod
...
CATALINA_OPTS=-Djava.awt.headless=trueIs this what you need?
CATALINA_OPTS is an environment variable. Here is how to define it and set it to a single value in Deployment configuration yaml:
...
spec:
...
template:
metadata:
labels:

spec:
containers:
- image: ...

env:
- name: CATALINA_OPTS
value: -Djava.awt.headless=true
