The container image i tried to deploy from docker hub is about 20 odd GB I managed to deploy it on the container app, got the Application Url but nothing happens. After some time, the browser just shows "stream timeout" And, now the status on the portal, for the container says Running status Degraded Status details Deployment Progress Deadline Exceeded. 0/1 replicas ready. And all the health probes are "disabled" :-( Questions please: How do i enable the health probes? When does Azure actually pull the image? Where can i see this log? I tried searching everywhere under monitoring but couldn't find it :-( Thanks in advance!

Hi @itsvkn If you've enabled ingress on the app, there's a default configuration that you can check under Container > select the container > Health Probes. You review these examples to change your configuration. You can also view the Container Apps Health Probe Failures that's a detector under Diagnose and solve problems blade. Your container will get pulled when a new revision is available, see Update and deploy changes in Azure Container Apps | Microsoft Learn for those details. But under the Diagnose and solve problems blade, click on Availability and Performance category to use those detectors to check for errors regarding loading the revision.

Thank you Ryan

But the health probes are all "disabled". I don't know how to enable them... looked at various documents. There seems to be no way to enable them on the portal

Any thoughts pls?

@itsvkn was there anything on the health probe detector under Diagnose and solve problems? To enable health probes:

Under Application, click Containers.

Select Edit and deploy and click the image name

Select Health probes and check the boxes

When you check the box, you'll be able to configure the health problem. You can leave the defaults or refer to the examples linked above.

@itsvkn you mean the check boxes are all disabled? If you try using the Azure CLI, do you get an error message?

az containerapp update \ --name <your-container-app-name> \ --resource-group <your-resource-group> \ --set properties.template.containers.livenessProbe.httpGet.path='/' \ --set properties.template.containers.livenessProbe.httpGet.port=80 \ --set properties.template.containers.livenessProbe.initialDelaySeconds=30 \ --set properties.template.containers.livenessProbe.periodSeconds=10

yes

I had copy pasted the image before, but hadn't clicked "add" so the image was left out ! :-(

Here is the image:

@itsvkn did you follow these instructions?

Under Application, click Containers.

Select Edit and deploy and click the image name

Select Health probes and check the boxes

You have to define the health probes in order to enable them. However, this is for custom health probes. If you're using a default container app setup, there are two log tables that we can also check; https://video2.skills-academy.com/en-us/azure/container-apps/log-monitoring?tabs=bash#query-log-with-log-analytics.
