Docker and Compose
Docker Compose production checklist
Turn a development Compose file into a production deployment with fixed code versions, restart rules, secrets, health checks and recovery.

Direct answer
Production Compose should build or pull an application image with a fixed version, avoid linking live source-code folders into containers, use production settings and protected secrets, define restart and health behaviour, save only required data, and have a tested backup and rollback path.
What this means in plain English
A Compose file that works on a developer’s laptop is a useful start, but production has different needs. The live version should use a known application image, keep passwords outside the file, restart sensibly after a failure and store important data somewhere that survives a replaced container.
Think about recovery before launch. You should know which folders contain real data, how to back them up, how to tell whether the app is healthy and how to return to the previous release. These checks matter more than adding lots of complicated Docker settings.
What changes between development and production?
| Image | Fixed version, repeatable build and application code included |
|---|---|
| Saved data | Named volumes or external services with backups |
| Recovery | Known rollback image and restore procedure |
A simple example
During development, a web container reads code straight from a laptop folder and uses a password written in compose.yaml. For production, the code is built into a versioned image, the password comes from a protected secret, uploads use a backed-up volume and the previous image is kept for rollback.
What to do, step by step
1. Check the final combined settings with docker compose config.
Start here before buying anything or changing several settings at once. It gives you a clear starting point based on image: fixed version, repeatable build and application code included. Write the result down so you can compare it later.
2. Remove development ports and source-code folder links.
Use the same files, versions and settings that the real project will use. A quick test with an empty or different setup can look successful while completely missing the problem you are trying to solve.
3. Add health checks and clear restart behaviour.
Try the busiest realistic situation, not the easiest one. Include the people, data, traffic or background work you genuinely expect, then watch for slowdowns and errors rather than relying on a single headline number.
4. Practise deployment, rollback and data restore.
Finish by checking the result against recovery: known rollback image and restore procedure. Keep the old setting or release available until you know the change works and can be reversed safely.
One more useful tip
Run docker compose config before deploying. It shows the final combined configuration after files and variables have been applied, which makes missing values and accidental development settings easier to spot.
Common mistakes and how to avoid them
Using latest tags.
This gives a misleading or unsafe result because it leaves out image. A better approach is to check the final combined settings with docker compose config, then check the result before making the change permanent.
Putting passwords directly in compose.yaml.
This gives a misleading or unsafe result because it leaves out saved data. A better approach is to remove development ports and source-code folder links, then check the result before making the change permanent.
Assuming a container restart repairs damaged data.
This gives a misleading or unsafe result because it leaves out recovery. A better approach is to add health checks and clear restart behaviour, then check the result before making the change permanent.
Words explained
- container
- A packaged, isolated way to run an application with the files and software it needs.
- image
- The read-only package used to create a container. A good production image can be rebuilt and traced back to a specific release.
- Compose
- Docker Compose is a file-based way to describe several containers, their settings, storage and networks as one application.
- volume
- Storage that survives when a container is replaced. Databases and uploaded files often need a volume.
- health check
- A small test that tells Docker whether the application inside a container is actually working.
- secret
- A password, token or key that must not be committed to source control or exposed to users.
Quick checklist
- Check the final combined settings with docker compose config.
- Remove development ports and source-code folder links.
- Add health checks and clear restart behaviour.
- Practise deployment, rollback and data restore.
Common questions
What is the simple answer?
Production Compose should build or pull an application image with a fixed version, avoid linking live source-code folders into containers, use production settings and protected secrets, define restart and health behaviour, save only required data, and have a tested backup and rollback path.
What should I check first?
Start with image: fixed version, repeatable build and application code included. That is usually more useful than choosing from a marketing label or copying somebody else’s setting.
How can I make the change safely?
Check the final combined settings with docker compose config. Then change one thing at a time, keep a backup or old version, and use the same real-world test after each change.
What is the easiest mistake to avoid?
Using latest tags. Avoiding that one mistake makes the rest of the comparison much more trustworthy.
