When I ran my YAML pipeline I should select the namespace and run it, default name space should be given as default.

Please suggest how it can be done.

Hello Diptesh Kumar,

You can parameterize the Kubernetes namespace in your DevOps YAML pipeline by using the parameters: block at the top of the YAML file. This allows you to enter a namespace during runtime, with a default fallback (in my example default).

example-

parameters:

- name: k8sNamespace

  displayName: 'Kubernetes Namespace'

  type: string

  default: 'default'

variables:

  imagePullSecret: acr-secret

  dockerRegistryServiceConnection: myDockerRegistrySC

  containerRegistry: acrk8stest2039.azurecr.io

  imageRepository: demo

  tag: latest

stages:

- stage: Deploy

  jobs:

  - job: DeployJob

    steps:

    - task: KubernetesManifest@0

      displayName: 'Create imagePullSecret'

      inputs:

        action: createSecret

        secretName: $(imagePullSecret)

        namespace: ${{ parameters.k8sNamespace }}

        dockerRegistryEndpoint: $(dockerRegistryServiceConnection)

    - task: KubernetesManifest@0

      displayName: 'Deploy App'

      inputs:

        action: deploy

        namespace: ${{ parameters.k8sNamespace }}

        manifests: |

          $(Build.SourcesDirectory)/manifests/deployment.yml

        imagePullSecrets: |

          $(imagePullSecret)

        containers: |

          $(containerRegistry)/$(imageRepository):$(tag)

Run the pipeline. it should trigger.
