After deployment my container stop after some minutes and doesn´t start again

Hi Danny Lan,

Thanks for reaching out to Microsoft Q&A.

There could be several reasons why your container stops working after some time and doesn't start again. I have given below the generic checkpoints which though might not fix your issue, would aid to find the cause of your error. Can you try this ?

• Access the container logs to see if there are any error messages or clues as to why the container is stopping. You can use the docker logs command to view the logs of a running container.
• Make sure your container is not running out of resources like CPU, memory, or disk space. Check if you have set any resource limits for the container and ensure they are appropriate for your application. You can use the docker stats command to monitor the resource usage of your container.
• Check if your container has a health check configured. If the health check fails, the container may be stopped by the orchestrator (Docker Swarm or Kubernetes). Ensure that your health check is properly configured, and your application is responding correctly to the health check requests.
• Check if your container requires any environment variables to be set correctly. Ensure that the environment variables are properly configured and passed to the container during deployment.
• Verify that the container has the correct networking configuration, such as port mappings and network settings. Ensure that the container can communicate with any external services or databases it depends on.
• If your application doesn't handle graceful shutdown properly, it may not be able to clean up resources or save state before the container stops. Ensure that your application has proper shutdown handling and can gracefully handle termination signals.
• Examine your deployment process to ensure that there are no issues with the way you are building, tagging, and deploying your container images. Verify that the correct image is being pulled and that the deployment is successful.
• If your application requires persistent data storage, ensure that you have set up persistent volumes correctly. Verify that the container can access the necessary storage volumes and that the data is being persisted correctly.

Pls note these are generic checks, make sure you tweak/change accordingly to your environment.
