A problem:
Docker arguments will pass from command line:
docker run -it -p 8080:8080 joethecoder2/spring-boot-web
-Dcassandra_ip=127.0.0.1 -Dcassandra_port=9042
However, when I do:
kubectl create -f ./singlePod.yaml
Kubernetes POD arguments will not pass from singlePod.yaml file:
apiVersion: v1
kind: Pod
metadata:
name: spring-boot-web-demo
labels:
purpose: demonstrate-spring-boot-web
spec:
containers:
- name: spring-boot-web
image: docker.io/joethecoder2/spring-boot-web
env: ["name": "-Dcassandra_ip", "value": "127.0.0.1"]
command: ["java","-jar", "spring-boot-web-0.0.1-SNAPSHOT.jar",
"-D","cassandra_ip=127.0.0.1", "-D","cassandra_port=9042"]
args: ["-Dcassandra_ip=127.0.0.1", "-Dcassandra_port=9042"]
restartPolicy: OnFailure
Question: How do I correctly specify arguments that will change at runtime?
I want to add two arguments that change at Kubernetes POD runtime, because
these should be configurable for each POD that is defined. Arguments for
the POD are: -Dcassandra_ip=127.0.0.1", "-Dcassandra_port=9042
I want the arguments to be accepted just like the Docker command line.
