Hi Lungu, Alexandru,
Microsoft does not currently provide a single official Docker image that includes both Azure CLI and kubectl pre-installed. Microsoft provides the base azure-cli image, which you can easily extend to include kubectl.
Building a Docker image that includes both Kubernetes (kubectl) and the Azure CLI involves creating a Dockerfile that specifies the installation steps for these tools. Choose a base image that has the necessary dependencies. Add the commands to install kubectl and the Azure CLI. Combine all the steps into a Dockerfile and save it to a file named Dockerfile. Open a terminal and navigate to the directory containing the Dockerfile. Build and Run the image. This will start a container with both kubectl and the Azure CLI installed, and you will be dropped into a bash shell where you can use these tools.
