Docker Buildx recommends JSON-form command arguments
JSONArgsRecommended
Docker Buildx build checks recommend using JSON-form arguments for certain Dockerfile instructions to avoid shell parsing surprises.
Error AtlasError Documentation and ResolutionObserved message
JSONArgsRecommended
Why it happens
- The Dockerfile uses shell-form arguments where JSON-array form is preferred.
- Shell parsing behavior can make command handling less predictable.
- Build checks are enforcing a safer or more explicit command style.
How to fix it
- Convert eligible Dockerfile instructions to JSON-array form.
- Review command quoting and argument splitting after conversion.
- Keep command form consistent across similar instructions.
