Login into Azure and set your current subscription

az login
az account set -s <subscription id>

Login into ACR

az acr login --name <acr name>.azurecr.io

Tag your image

docker tag httpd <ACR name>.azurecr.io

Push the image to ACR

docker push <ACR name>.azurecr.io

Check if your image was uploaded properly

az acr repository list -n <ACR name>
