Question

I am trying to use the `Kubernetes@1` Azure Devops Task to `patch` a single name-vaue pair in an already existing `ConfigMap`

## YAML snippet

```yaml
  - task: Kubernetes@1
    displayName: 'update configmap with version'
    inputs:
      connectionType: 'Azure Resource Manager'
      azureSubscriptionEndpoint: ${{ parameters.azserviceconnection }} # name of the Azure Service connection
      azureResourceGroup: ${{ parameters.aksresourcegroup }} # the resource group which has the AKS cluster
      kubernetesCluster: aks001-dev
      namespace: powertrading-dev
      configMapName: shared-configmap
      useConfigMapFile: false
      configMapArguments: --from-literal=key1=some_value_from_yaml
    continueOnError: false      

My intent is to replicate the following command:

kubectl --namespace powertrading-dev patch configmap shared-configmap -p  "{ \"data\" : { \"key1\" : \"some_value_from_yaml\" }}"

I can't get the Devops task to update a single key-value pair. Any suggestions ?

Option-1-Using the configMapName option

I have explained above. This doe not work.

Option-2-Using the patch command

I have also tried doing a patch

  - task: Kubernetes@1
    displayName: 'update configmap with version'
    inputs:
      connectionType: 'Azure Resource Manager'
      azureSubscriptionEndpoint: ${{ parameters.azserviceconnection }} 
      azureResourceGroup: ${{ parameters.aksresourcegroup }}
      kubernetesCluster: ${{ parameters.aksresourcename }}
      namespace: powertrading-dev
      command: patch
      arguments: "configmap shared-configmap --patch  '{\"data\": {\"key1\": \"newvalue1 from yaml\" }' "

But, this fails with the following error:

2024-09-19T20:40:02.7681122Z [command]/opt/hostedtoolcache/kubectl/1.31.0/x64/kubectl patch -n powertrading-dev configmap shared-configmap --patch '{data: {key1: newvalue1 from yaml }' -o json

The double quotations are being stripped off.

Can somebody suggest how I may get the above to work?
