How does this skill handle the next.config.js/ directory bug?

The skill identifies the incorrectly created directory, ensures it is added to .gitignore, and updates the Docker Compose file to point to the valid next.config.mjs file.

Why does Docker create a directory instead of mounting my Next.js config?

If Docker Compose points to a file that doesn't exist on the host, Docker defaults to creating a directory at that location. This often happens during the transition from next.config.js to next.config.mjs.

Are the mounts configured as read-only?

Yes, the skill applies the :ro flag to mounts to ensure the container environment cannot inadvertently modify your host configuration files.

Does this work with custom Docker Compose file names?

Yes, the skill scans the repository for standard Docker Compose YAML files and identifies relevant volume mappings for Next.js services.

Deployment & DevOps

Resolves Docker Compose bind mount issues for Next.js by correctly mapping configuration files and preventing erroneous directory creation.

About

This skill automates the resolution of a common Docker Compose bug where missing source files cause Docker to create a directory instead of mounting a file. It specifically targets Next.js projects using ESM configuration, ensuring that next.config.mjs is correctly mapped as a read-only volume. It streamlines the transition from CommonJS to ESM configs in containerized environments by identifying path mismatches, cleaning up accidental phantom directories, and updating project ignore files to prevent recurrence.

Key Features

Updates Docker Compose bind mounts to use the correct ESM extension
Removes and ignores 'next.config.js/' directories created by Docker errors
Detects existing next.config.mjs files in the project root
Validates dev container configurations to ensure successful mounting
Configures mounts as read-only (:ro) to follow security best practices
1 GitHub stars

Use Cases

Migrating a Next.js project from CommonJS to ESM within a Dockerized environment
Fixing 'directory not found' or 'is a directory' errors in Docker Next.js logs
Ensuring local configuration changes are correctly reflected inside dev containers
