You can create a scripts/wait-for-health.sh script that loops over your critical services (such as postgres, redis, and minio) and checks their health status using docker inspect. This ensures your build doesn’t proceed until all containers are reported as healthy.
Here’s what that script should do: for each service, it checks if docker inspect -f '{{.State.Health.Status}}' returns healthy, and if not, it waits and tries again every few seconds. Once all services pass, the script completes and the test phase can safely begin. Don’t forget to mark this script as executable with chmod +x scripts/wait-for-health.sh, and then invoke it during your before_install phase in .travis.yml right after docker-compose up -d.
For Docker layer caching, the common mistake is assuming that simply caching $HOME/.docker will persist image layers — but this rarely works reliably across Travis CI builds. Instead, you should explicitly save your Docker image as a tarball using docker save before the cache phase, and then load it again in a future build using docker load. For example, you could use docker save my-app:latest > my-app.tar in the before_cache section, and restore it in before_install with docker load < my-app.tar. This approach makes Docker image reuse deterministic and avoids layer rebuilds on every build.
In summary, you’ll need to create a bash script to wait for health checks, explicitly manage Docker caching with docker save/load, and stick to container names for intra-service communication. These fixes combined will make your Travis + Docker Compose setup faster, more stable, and easier to debug. Let me know if you want a sample repo to demonstrate it all.
