Docker Compose Validator
Docker Compose Validator: Parses YAML only enough to require a root object with a services object and list service keys; it does not validate the Compose schema or run containers.
About this docker compose validator
Docker Compose Validator — browser-based utility.
How this tool works
Parses YAML and checks only that the root and its services property are objects, then lists service keys. It does not apply the Docker Compose schema or validate service declarations, port bindings, networks, or dependencies.
- Parse the entered YAML text.
- Require a root object with an object-valued services property.
- List the services object keys in the result.
Worked example
Scenario: Validate the minimum YAML shape with one service key.
Sample input:
Processing: Parse YAML and ensure top-level services is an object.
Illustrative output:
Limits and verification
It does not validate the Compose schema, images, builds, ports, volumes, networks, dependencies, interpolation, profiles, extensions, engine compatibility, or create containers.
Examples demonstrate an expected workflow; they do not prove every input or every branch of an external specification. Check important results with an independent source before using them for money, security, compliance, safety, or irreversible file changes.
Browser processing boundary
Tool input is processed by code running in the browser and is not intentionally sent to a CZOA processing API. The page can still request ordinary site assets, analytics, or advertising when those services are enabled. Browser extensions and managed-device software remain outside this tool's control.

- Click the action button or observe immediate live calculations rendered in your browser runtime.
- Inspect the resulting output and any diagnostic messages, then copy or download the result if needed.
Frequently asked questions
What Compose structure does this validator accept?+
It parses YAML and requires an object with an object-valued `services` property, then returns the service-key names. It is a shape check, not full Compose validation.
What result does one web service produce?+
For `services:` containing `web:`, the browser result is `Valid compose shape. Services: web`. It checks root `services` detection and key listing for that YAML input.
Which Compose rules are not checked?+
It does not apply the Docker Compose schema or validate image references, ports, networks, volumes, depends_on, environment, duplicate YAML keys, interpolation, or deployment behavior.
Does it contact Docker or run a stack?+
No. The browser test parses the entered Compose text and reads the page result; its tool request log contains no request carrying that text. It does not create a stack or establish the absence of ordinary page resources.
