I'm having a hard time to debug my container on Azure Container Apps. Before, I had a K8S cluster, where I could query my pod with kubectl and find quite easily the reason why the container was not starting, or failed to run after starting.
Here on ACA, I feel lost. I have nothing in my "Log Stream" on System nor Console. In normal Log, I don't have the table ContainerAppSystemLogs_CL where most of people debug their app.
I only have access to ContainerAppSystemLogs and the only info I have inside it is:
Successfully pulled image 'artifacts.xxxxxxxxxx.xxx/xxxxxxx/xxxxx:xxxxxx' in 65.1182032s
Created container 'XXX'
Started container 'XXX'
Probe of StartUp failed with status code: 1 # For 10 minutes and more than 300 counts
Deactivated apps/v1.Deployment k8se-apps/XXX-sandbox--8tmx1eh from 1 to 0
Container 'XXX' was terminated with exit code '' and reason 'ManuallyStopped'
My auto scaller is an http scaller from 0 to 1, that's why it is stopping. But it's not "ManuallyStopped", it's from the scale rule.
I removed Probes (liveness and health) for better debugging, but it does not help. My container is made for sandboxing. So it's a basic image with entrypoint a "while true; do sleep 10000; done". Because I want to connect to it, and test flows and code direclty inside a container.
I have no idea where to look to find a lead to debug this.
Here is what the JSON template of my ressource looks like:
