“It works on my machine” is no longer an argument
Docker solves the classic development problem: the application works the same way on the developer's laptop, on staging, and in production. Containers are isolated, reproducible, and deploy in seconds — without manual dependency installation and version conflicts.
What we do
We write a Dockerfile for each service and set up Docker Compose for local development and production. We optimize images via multi-stage build — the final size is 5-10 times smaller, they download faster and take up less space on the server.
- A Dockerfile for each service — minimal base image, correct layer order, caching
- Docker Compose — networks, volumes, environment variables, service dependencies for dev and prod
- Multi-stage builds - the build and runtime are separated, and only what is necessary ends up in the final image
- Private Docker Registry — storing images within your perimeter without dependence on Docker Hub
- Integration into the CI/CD pipeline — automatic build and publishing of images on every commit
- Scanning images for CVEs — vulnerabilities are found before deployment, not after
- Rollback to the previous version in seconds - the previous image is always available in the registry
Migration of existing projects
If the application already runs on bare metal or a VPS — we move it into containers without service downtime. Dependency audit, decomposition into services, reproducibility check in a clean environment.
