I have my azure pipeline doing a kubernetes@1 task with my kubernetes config:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: tennant-service-deployment
  labels:
    app: tennant-service
spec:
  replicas: 3
  selector:
    matchLabels:
      app: tennant-service
  template:
    metadata:
      labels:
        app: tennant-service
    spec:
      containers:
        - name: tennant-service
          image: cronesharedwesteurope.azurecr.io/tennant-service:dev
          ports:
            - containerPort: 80   
      imagePullSecrets:
        - name: registrysecret

You can see that at the moment my image is hard coded in my yaml file (tennant-service:dev).

I want the user to tell me witha azure devops pipeline parameter which version he wants (e.g, dev / 1.0 / latest). But because the kubernetes is a yaml config file, I can't change it with a parameter, can I? Are there any tools to do exactly this?

This is what we do at work,

1. Create a build pipeline that builds the docker image with a tag, and the tag is the pipeline build number, e.g. #1.6.1-TenentServiceImage. (Assume that you have already pushed the image to ACR during the build process).

2. In your deployment YAML pipeline, add a resource,

      resources:
       pipelines:
        - pipeline: TenentServiceImage
          source: Tenent Service Image
          branch: master
   

3. In the same YAML, now you can reference the resource in your image path,

    image: cronesharedwesteurope.azurecr.io/tennant-service:$(resources.pipeline.TenentServiceImage.runName)
   

4. When your devs try to deploy the container, they click Run and should see a new selection dropdown Resource and select the build they want to deploy.

Microsoft has some good documentation on setting up an Azure DevOps pipeline for Kubernetes containers. The example features use of the KubernetesManifest@0 task in the pipeline allowing to specify the container tag with a pipeline variable or parameter.
