Are all environment variables parsed accurately?

Yes. The converter handles multiple -e and --env declarations, including values containing spaces or quotes, preserving their assignment inside the environment list block.

Does this output work with Docker Compose v2?

Yes, the generated syntax conforms to the latest official Docker Compose Specification supported universally by modern `docker compose` installations.

Can I combine multiple docker run outputs into a single Compose file?

Yes. You can convert each command separately, copy the service blocks, and merge them under the top-level 'services:' key in one docker-compose.yml file.

How do I resolve volume permission issues with mounted folders?

Ensure the host folder referenced by the volume mount has appropriate read/write permissions for the user ID running inside the container.

Is my command history or server data uploaded anywhere?

No. All flag parsing, tokenization, and YAML compilation execute 100% locally in your client browser runtime.

Docker Run CLI to Docker Compose YAML Converter

Docker has established itself as the global standard for building and running containerized software. In the early stages of development, engineers frequently spin up containers via quick terminal commands such as `docker run -d -p 8080:80 -v ...`. However, as infrastructure scales to include interconnected services (web servers, databases, caching layers), relying on ephemeral shell commands becomes brittle, error-prone, and impossible to version control effectively.

Docker Compose provides a declarative YAML specification designed to define and manage multi-container applications. With a single `docker compose up -d` command, entire stacks can be provisioned consistently, establishing the foundation of Infrastructure as Code (IaC) in Git repositories.

OrvoKit Docker Run to Compose Converter parses complex docker run invocations—including port bindings (-p), volume mounts (-v), environment variables (-e), network references (--network), restart policies (--restart), memory caps (-m), and daemon flags (-d)—and transforms them instantly into clean, standardized docker-compose.yml files.

CLI Tokenization & Compose Specification Schema Mapping

An automated command-line tokenizer that extracts flags, arguments, and quotes to reconstruct an idiomatic YAML service tree.

CLI Arguments to Compose TransformationMathematical Formulation

ParseRun(CLI) -> { image: Image, ports: [-p], volumes: [-v], environment: [-e], restart: [--restart], container_name: [--name] }

Short (-p, -v, -e) and long (--publish, --volume, --env) flags are normalized, values wrapped in single or double quotes are stripped safely, and arguments are partitioned into idiomatic YAML arrays or key-value dictionaries.

--net / --network	--network	networks	List or Map	networks: ["custom-net"]

* Under modern Compose Specification standards, top-level version declarations are optional and omitted for brevity.

How to Use

11. Paste docker run Command

Paste your raw docker run terminal command or one-liner into the input box.

22. Specify Service Name & Version

Customize the target Compose service name (e.g., app, api, db) and optional compose version metadata.

33. Review Generated Compose YAML

Inspect the structured, properly indented docker-compose.yml output generated in real-time.

44. Copy and Deploy

Click [Copy], save the output as docker-compose.yml in your project root, and execute `docker compose up -d`.

💡 Production Docker Compose Guidelines

✓ Always Quote Port Numbers

In YAML, unquoted numbers with colons like 80:80 or 22:22 can be misparsed as base-60 sexagesimal numbers. Always wrap ports in quotes ("8080:80").

✓ Use Relative Volume Paths

Prefer relative paths (./data:/app/data) rather than absolute local paths (/Users/name/...) to ensure portability across developer machines.

✓ Externalize Secrets to .env

Avoid committing raw passwords directly into docker-compose.yml; reference them via ${DB_PASS} backed by a local .env file.

⚠️ Common Pitfalls & Mistakes to Avoid

❌ Including -d Flag Inside YAML

✅ The -d (detach) option is a CLI execution flag, not a YAML attribute. Execute `docker compose up -d` instead.

❌ Confusing Container Port with Host Port

✅ In the syntax HOST:CONTAINER (e.g. 8080:80), remember that the second number is the port listened to inside the container.

6 Q&As

`docker run` executes an isolated container directly in the terminal, while `docker compose` defines a declarative, reproducible stack of multiple interconnected containers managed together via YAML.
