I built BeforeUp to catch Docker Compose problems before deployment

说明与用途

BeforeUp 检查 Docker Compose 的宿主机准备情况，检测端口冲突和缺失的绑定挂载，降低部署失败率。

问题

Docker Compose configurations can be valid yet fail at runtime due to host‑side conditions like occupied ports or missing bind‑mount directories.

结果

BeforeUp identifies host‑side problems that Docker Compose alone cannot detect, reducing deployment failures caused by port conflicts or missing bind‑mounts.

工作流

• 1. Create or obtain a Docker Compose file.
• 2. Run beforeup check -f <compose-file> to validate host conditions.
• 3. Review the PASS/FAIL report, addressing any blockers or warnings.
• 4. (Optional) Use beforeup compare -f <compose-file> to compare proposed changes against the currently running stack.

证据

docker compose config can succeed even when a published port is already occupied or a required bind‑mount directory doesn't exist.

来源

BeforeUp adds that inspection: beforeup check -f compose.yaml

PASS COMPOSE PASS DAEMON WARNING PORT_IN_USE Host tcp port 18080 already has a listener. BLOCKER BIND_MISSING A bind source for this service does not exist.

来源

BeforeUp doesn't predict whether an application will become healthy, whether an image can be downloaded or whether two services will communicate successfully.
