Docker & container tools
Container workflows break in small, repetitive ways: a docker-compose.yml with a port already claimed by another service, a docker run command with mounts typed out by hand, a Dockerfile stage that references a build argument that was never declared. These tools catch that class of mistake before you run docker build or docker compose up and have to dig through logs to find the line that's wrong.
Each tool matches one file or command you actually write. The Docker Compose workbench reviews existing YAML for port and dependency problems, while the Docker Run builder goes the other way and assembles a docker run command from ports, mounts and environment variables you fill in. The Dockerfile editor adds line-level diagnostics to multi-stage builds, and the Docker image parser breaks an image reference down into registry, repository, tag and digest so you can see exactly what a pull will fetch.

Docker & Containers tools FAQ
Two services in the same Compose file, or a service and something already running on the host, are mapped to the same host port. The Docker Compose workbench reads the file and flags conflicting port mappings and dependency ordering issues before you run docker compose up.
An image reference can carry a registry host, repository path, tag and a @sha256 digest at once, and the digest always wins if both are present. The Docker image parser splits a reference into those four parts so you can see exactly which image a pull resolves to.
ARG is only available during the build and disappears from the final image; ENV persists into the running container. The Dockerfile editor checks multi-stage Dockerfiles line by line, which helps catch a build ARG used where a runtime ENV was actually needed.
