How to Use the Docker Helper

This tool demystifies Docker commands by providing a user-friendly interface for common configurations.

For `docker run` (Single Container)

  1. Enter the name of the Docker image you want to run (e.g., `node:18-alpine`).
  2. Give your container a name for easy reference.
  3. Toggle flags like `-d` to run it in the background.
  4. Add port mappings to expose your application (e.g., map host port `3000` to container port `3000`).
  5. Add volume mappings to persist data or sync code.
  6. Copy the final command from the "Generated Command" box.

For `docker-compose` (Multiple Containers)

  1. Click "Add Service" to define each part of your application (e.g., `webapp`, `database`).
  2. For each service, specify the image, container name, and restart policy.
  3. Add port, volume, and environment variable mappings just like with `docker run`.
  4. The `docker-compose.yml` file on the right will update live.
  5. Copy the generated YAML and save it as `docker-compose.yml` in your project. Run `docker-compose up` to start your entire stack.
