How to pass arguments in kubernetes?-CodePudding

I am running my docker image in my local machine (executing my performance test based on the arguments provided) with the following command like this

whereas, satheeshpandianj/my-perf-app is my image name and rest (QA Commerce ListMarkets 1 5 Volvo) are arguments passed to this image to run. I have already pushed this image to docker hub. I want to run this docker image in kubernetes. I wrote the deployment yaml file like below.

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
   app: perf
  name: perf
spec:
  replicas: 1
  selector:
   matchLabels:
    app: perf
  template:
   metadata:
     labels:
      app: perf
   spec:
     containers:
       image: docker.io/satheeshpandianj/my-perf-app
       name: perf
       args: ["QA", "Commerce", ListMarkets", 1, 5, "Volvo"]

When I am executing "kubectl apply -f perf.yaml", I am getting a below error

Can someone help me to resolve this error? Or please correct me what changes need to be made in my yaml file. Thanks in advance.

You are getting this error because the spec.containers, expects a list. You have to update your yaml to this:

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
   app: perf
  name: perf
spec:
  replicas: 1
  selector:
   matchLabels:
    app: perf
  template:
   metadata:
     labels:
      app: perf
   spec:
     containers:
     - image: docker.io/satheeshpandianj/my-perf-app
       name: perf
       args: ["QA", "Commerce", ListMarkets", 1, 5, "Volvo"]

Yes, only the - is missing
