Need to pass command line arguments for the docker containers appContainer1 & appContainer2 in the pod.yaml.
pod.yaml
apiVersion: v1
kind: Pod
metadata:
name: microservices
labels:
app: apps
spec:
containers:
- name: appContainer1
image: gcr.io/mybucket/appContainerImage1
ports:
- containerPort: 8080
- name: appContainer2
image: b.gcr.io/mybucket/appContainerImage2
ports:
- containerPort: 9090
In docker, I can pass the command line arguments via environment variable(-e)
docker run --rm -it -p 9090:9090 -e spring.profiles.dynamic=local applicationimage1
Similarly, I need to pass command line arguments when the containers run inside kubernetes.

To define arguments for the command, include the args field in the configuration file. The command and arguments that you define cannot be changed after the Pod is created. The command and arguments that you define in the configuration file override the default command and arguments provided by the container image.
kubectl provides the auth can-i subcommand for quickly querying the API authorization layer. The command uses the SelfSubjectAccessReview API to determine if the current user can perform a given action, and works regardless of the authorization mode used.
The Kubernetes command-line tool, kubectl, allows you to run commands against Kubernetes clusters. You can use kubectl to deploy applications, inspect and manage cluster resources, and view logs. For more information including a complete list of kubectl operations, see the kubectl reference documentation.
It sounds like you don't actually want command line arguments, but environment variables - and you can use env for that:
- name: appContainer1
image: gcr.io/mybucket/appContainerImage1
ports:
- containerPort: 8080
env:
- name: spring.profiles.dynamic
value: local
You can use command line arguments:
- name: appContainer1
image: gcr.io/mybucket/appContainerImage1
ports:
- containerPort: 8080
args:
- foo
- bar
- "String containing:colons:"
