Spring Boot App Can't Find Database Table When Run in Docker Despite Passing Tests
A developer's Spring Boot app passes its test suite against a Dockerized MySQL database, but the running application reports the table doesn't exist when hitting the same endpoint. Points to a recurring class of schema/runtime mismatch in containerized database setups.

Similar Problems
surfaced semanticallySpring Boot Cannot Connect to MySQL Service Inside Docker Compose Network
A Spring Boot microservice fails to establish JDBC connections to a MySQL container in a Docker Compose setup due to service startup ordering. Everything works correctly outside Docker but the containerized environment breaks database connectivity.
Spring Boot Cannot Reach PostgreSQL in Docker When Using Localhost Connection String
Developers configuring Spring Boot to connect to PostgreSQL running in Docker frequently hit authentication failures because localhost inside a container refers to the container itself, not the host machine. This common Docker networking misunderstanding blocks local development setup. The fix is well-documented but Spring Boot error messages do not surface the root cause clearly.
Ktor Docker build fails with missing buildFatJar Gradle task
A developer building a Ktor application in Docker hits "Unable to access jarfile /app/app.jar" because the referenced buildFatJar Gradle task does not exist in their project, and running it directly confirms the task is not found in the root project. The Dockerfile assumes a Gradle task that was never configured in the project's build files.
Dynamic Docker container URL not accessible after spin-up
Developers building code-generation platforms that spin up ephemeral Docker containers cannot easily retrieve the localhost URL where the running application is accessible. Docker only returns the container ID on start, requiring additional inspection steps that break automated preview workflows. This is a friction point for anyone building vibe-coding or sandbox environments.
Docker containers lose DNS resolution after host reboot due to stale resolv.conf
A long-time Docker user on Debian reports that after a host reboot, containers start successfully but cannot reach the internet because they fail to pick up the host resolv.conf; restarting the containers a few minutes later fixes it. This points to a startup-ordering race between Docker and the host DNS/networking services that surfaces only after a reboot, not during normal operation.
