Question

I cannot delete an Azure Container App, as it remains stuck in "Status=Unknown"

Alexander Harrington 25

I have been trying to delete an Azure Container App over the last five hours.
The deletion just keeps spinning, and the status of the app is stuck as "Unknown".

Hi @Alexander Harrington

Thank you for reaching out to Microsoft Q&A

As Delete is an Async operation, it may take some time for the container app to get deleted.

As a workaround, try to run below Azure CLI commands or call a rest api to perform deletion.

az containerapp delete --name ACA_NAME --resource-group RG_NAME --yes
az containerapp env delete --name $ENV_NAME --resource-group RG_NAME --yes

If you have a VNET, Run the commands below by removing the Service Association Link and then try deleting the Container app:

Remove Service association link:

az rest --method delete --uri https://management.azure.com/subscriptions/<subscription id>/resourceGroups/<resource group>/providers/Microsoft.Network/virtualNetworks/<vnet name>/subnets/<subnet name>/providers/Microsoft.ContainerInstance/serviceAssociationLinks/default?api-version=2018-10-01

Remove Delegation:

az network vnet subnet update --resource-group <resource group name> --name <subnet name> --vnet-name <vnet name> --remove delegations

Delete VNET
az network vnet delete --resource-group <RESOURCE_GROUP> --name <VNET_ID>

Delete Container app:
az containerapp delete --name ACA_NAME --resource-group RG_NAME --yes

Delete Container app environment:
app env delete --name $ENV_NAME --resource-group RG_NAME --yes

Alright, I will give this a shot.

Unfortunately, this has the same issue; the delete command just hangs.
I have also - separately - experienced a lot of issues with even provisioning the app in the first place these last few days, so I will give it some rest for now. I will return Monday and give it a try.

Hi @Alexander Harrington

Thank you for your response.

I have seen the delete operation hanging, but after 24-48 hours the resource gets deleted from the Portal and is no longer visible. So, I'll recommend waiting.

What you can try if you only want to delete container app without touching VNET is try below commands:

# Deactivate all revisions (stops runtime quickly) az containerapp revision list \ --name ACA_NAME \ --resource-group RG_NAME \ --query "[].name" -o tsv | while read rev; az containerapp revision deactivate \ --name ACA_NAME \ --resource-group RG_NAME \ --revision "$rev" || true # Optional: turn off ingress and Dapr to minimize spec az containerapp update \ --name ACA_NAME \ --resource-group RG_NAME \ --ingress external --target-port 0 --transport auto --enabled false || true az containerapp dapr disable -n my-containerapp -g MyResourceGroup

If this does not work, try using Rest-API to perform the deletion:

https://learn.microsoft.com/en-us/rest/api/resource-manager/containerapps/container-apps/delete?view=rest-resource-manager-containerapps-2025-07-01&tabs=HTTP

You can also try clearing your browser cache, cookies and history and retry the delete operation from the Portal. Also, try to perform the deletion via Incognito/InPrivate window of your browser.

If your Azure Container App is stuck in the "Status=Unknown" state during deletion, you may need to manually delete the associated Virtual Network (VNet) that is being used by the Azure Container Apps environment. Here are the steps you can follow:

Identify the VNet being used by the environment you're trying to delete. You can do this by running the following command in Azure CLI, replacing <RESOURCE_GROUP> and <ENVIRONMENT> with your actual resource group and environment names:
```
   az containerapp env show --resource-group <RESOURCE_GROUP> --name <ENVIRONMENT>
```
Look for the infrastructureSubnetId in the output to find the VNet ID.

Once you have the VNet ID, delete the VNet manually using the following command:

   az network vnet delete --resource-group <RESOURCE_GROUP> --name <VNET_ID>

After deleting the VNet, you can attempt to delete the Azure Container Apps environment again with:
```
   az containerapp env delete --resource-group <RESOURCE_GROUP> --name <ENVIRONMENT> --yes
```

This should help resolve the issue and allow you to delete the container app successfully.

For anyone seeing this AI-generated answer, please, do not use it. It is not possible to delete the VNET before the app, and if it was, it would be a potentially dangerous decision to make, as it could affect other parts of your infrastructure, release public IPs, etc.
