I am trying to deploy my services on AKS using Azure Devops pipeline. Everything works fine except for applying my latest build on Kubernetes service. I am using following command to deploy the service.

#- script: docker build -f ./ContainerApp/Dockerfile -t $(dockerServer)/$(imageName) . 
#  displayName: 'Container Build'
#
#- script: docker login -u $(dockerId) -p $(dockerPassword) $(dockerServer)
#  displayName: 'Container Service login'
#
#- script: docker push $(dockerServer)/$(imageName)
#  displayName: 'Container Push'
#
    - script: kubectl apply -f ./azure-kubernetes-deployment.yml
      displayName: 'deploying to Kubernetes'

It works fine when i run this command from my local machine, but doesn't work on pipeline. when i run on pipeline following error occures.

can anyone suggest what command i am missing?
