I am following this article. I have an Azure container registry as shown below image and I have defined the task as below.

az acr task create \
--name krushnaTask \
--registry krushna \
--cmd python-hello \
--schedule "1 10 * * *" \
--context /dev/null

When the Azure is running the task it is giving below error :

2020/06/02 11:02:03 Alias support enabled for version >= 1.1.0, please see https://aka.ms/acr/tasks/task-aliases for more information.

What can be done so the ACR task can access the docker image?

is the image exists in docker registry? – Sajeetharan
Yes I can pull the image to my local system also using command like docker pull krushna.azurecr.io/python-hello:latest – Krushna
have you looked at this: docs.microsoft.com/en-us/azure/container-registry/… – djsly

I'm pretty sure the problem is that you need to input the image as krushna.azurecr.io/python-hello:tag since the image is in your ACR. When you input the image as python-hello, it means it's a public docker image in Docker hub, so it caused the error because it cannot find the image in the Docker hub. Change the command like below and it will work well:

az acr task create \
--name krushnaTask \
--registry krushna \
--cmd krushna.azurecr.io/python-hello \
--schedule "1 10 * * *" \
--context /dev/null

When creating ACR Tasks, you should provide a git-access-token if your registry has RBAC enabled

--git-access-token
The access token used to access the source control provider.

https://docs.microsoft.com/en-us/cli/azure/acr/task?view=azure-cli-latest#az-acr-task-create

you can create the access token from this DOC
