Docker Compose Static Check
Parse Compose YAML locally, check services, ports, volumes, dependencies, and environment configuration, without starting Docker.
How to use Docker Compose static checking
Docker Compose static checks process input only in the current browser; they do not upload, connect to the network, or save user data.
Input content
Paste or load a Compose YAML file.
Select a processing method
Check service names, image/build, ports, volumes, depends_on, environment, and healthcheck.
Check and export
View errors and warnings by the YAML path, or copy or download the check results.
Limitations and Notes
- Performs only static structural checks, without expanding actual environment variables or running containers.
- Passing the check does not mean the Docker engine, image, network, or host path will necessarily work.
- The tool only provides locally processed results; important configurations, secrets, documents, and published content must still be reviewed in the target environment.
FAQ
Will the input be uploaded to a server?
No. The page only uses browser memory, the local file API, and local resources already provided with the site.
Will the checker pull images?
No. It does not execute the Docker command, connect to the network, or read host files and environment variables.
Why do the results still require manual review?
Edge-case syntax, regional standards, third-party readers, and target runtime environments may differ; the tool does not replace final validation.
