About this tool
Docker Compose Analyzer is a browser-based static analysis tool for inspecting Docker Compose YAML files. It parses Compose services, images, builds, ports, volumes, networks, dependencies, environment configuration, and selected runtime settings, then highlights common configuration and security risks.
What is a Docker Compose Analyzer?
Docker Compose files describe multi-container applications and define how services, networks, volumes, images, and runtime settings work together. As Compose files grow, configuration problems can become difficult to spot by manually reviewing YAML.
Docker Compose Analyzer provides a structured view of a Compose file and highlights configuration patterns that deserve attention before the file is used in development, CI/CD, or deployment workflows.
What does this tool analyze?
The analyzer parses the Compose YAML and extracts service-level configuration before running a set of static checks.
- Docker images and build configuration
- Published ports and host bindings
- Named and bind-mounted volumes
- Networks and service network membership
- depends_on service relationships
- Environment variables and environment files
- Restart policies
- Commands and entrypoints
- Privileged containers
- Additional Linux capabilities
- Read-only container filesystems
- Fixed container names
- Healthcheck configuration
- Named volumes and custom networks
Common configuration and security findings
The analyzer identifies patterns that can lead to operational, portability, or security problems. These findings are recommendations rather than proof that a Compose configuration is incorrect.
- Images using the latest or an otherwise unpinned tag
- Services without an image or build configuration
- Privileged containers
- Environment variables that appear to contain secrets
- Host filesystem paths mounted into containers
- Ports published on all host interfaces
- Duplicate host port assignments
- depends_on references to unknown services
- Additional Linux capabilities
- Fixed container names that can interfere with scaling
- Services using dependencies without healthchecks
Why review a Compose file before deployment?
A Compose file can define networking, storage, credentials, exposed ports, and container privileges in a single document. Reviewing these settings before deployment can help catch mistakes before they become runtime problems.
Static analysis is particularly useful during code review and CI/CD workflows because it can provide a quick second look at configuration without requiring access to the target Docker environment.
Security and privacy
Docker Compose Analyzer performs static parsing and analysis in your browser. The tool does not need a Docker daemon, Kubernetes cluster, or remote infrastructure connection to inspect the YAML.
Because Compose files may contain credentials or other sensitive configuration, avoid sharing files containing real secrets. Even when analysis is performed locally, you should follow your organization's security and secret-management policies.
Limitations
This tool performs static analysis of the supplied Compose YAML. It does not start containers, contact a Docker daemon, pull images, resolve runtime dependencies, inspect the host, or determine whether an application will actually work at runtime.
A warning or informational finding does not necessarily mean that a configuration is wrong. Some settings are intentional and depend on the application's architecture and deployment environment.
Frequently Asked Questions
▶Does Docker Compose Analyzer run my containers?
No. It only parses and analyzes the supplied Compose YAML. It does not start containers or connect to a Docker daemon.
▶Can it detect Docker Compose security problems?
It can identify several common configuration risks, such as privileged mode, potentially exposed ports, possible secrets in environment variables, host path mounts, and additional Linux capabilities. It is not a complete security scanner.
▶Does the analyzer support modern Docker Compose files without a version field?
Yes. The Docker Compose Specification does not require the older top-level version field, and the analyzer treats files without one as Compose Spec configurations.
▶Does it connect to my Docker environment?
No. The analyzer is a static YAML analysis tool and does not require access to your Docker host, containers, images, or networks.
▶Can I use the findings in production reviews?
Yes, as a supplementary configuration review. Findings should still be evaluated against your application's requirements, security policies, and deployment environment.
