My Spring Boot production deployment repeatedly gets stuck at "Creating containers..." for 10+ minutes.

Project: linzz-impressions

Service: ravishing-inspiration

Environment: production

Region: US East (Virginia, USA)

What I have verified:

• Docker build completes successfully.
• Maven package completes successfully.
• Docker image is successfully created and published.
• The application starts successfully when the container runs.
• Spring Boot starts on port 8080.
• MySQL connection succeeds.
• JPA initializes successfully.
• Tomcat starts successfully on port 8080.
• No application exception is shown in the runtime logs.
• Public networking is correctly configured for port 8080.
• No Healthcheck Path is configured.
• CPU and memory usage are not exhausted.
• The service has a persistent volume mounted at /app/persist.
• MySQL uses a separate mysql-volume.
• The same issue occurs with both GitHub deployments and Railway CLI (railway up).

The runtime logs previously showed:

"Started LinzzImpressionApplication"

"Tomcat started on port 8080"

A previous deployment diagnosis also reported that the build finished and image was published, with no build or application error.

Please check whether container provisioning or persistent-volume mounting is causing the deployment to remain stuck at "Creating containers".

I do not want the existing application volume or MySQL volume deleted/recreated because they contain production data.
