Dockerfiles that keep local and staging honest
Practical Dockerfile habits for PHP/Laravel stacks and shared services.
Pin what you ship
I pin base image digests or minor versions so composer install does not silently change behavior when a teammate pulls latest.
- Separate build and runtime stages
- Copy only manifests before dependency install for better cache
- Use .dockerignore to keep contexts small
One compose file, many environments
Environment variables drive ports and credentials; the compose topology stays stable so onboarding is one command.
Containers are documentation that executes.
