Docker Swagger UI

metz/swaggerui is a Docker image for the Swagger UI, that supports publishing Swagger Specs via API and volume mount.

Getting started

You can pull and run a pre-built Docker image directly from Dockerhub:

docker run --name swaggerui -p 80:8080 metz/swaggerui

This will start the Swagger UI using the default petstore JSON. Then you can access the Swagger UI directly from a browser:

• Swagger UI: http://localhost:80/

Publish a custom Swagger Spec

In order to supply your own Swagger Spec (swagger.json), you will need to either publish it via the API or mount it with a volume.

Both solutions can be combined, so that the currently published Swagger Spec will be synced with the mounted directory.

API

For more details about the API, see the API overview.

A new Swagger Spec can be published by sending a POST request with the Swagger JSON in the body to the /publish endpoint:

curl -v -X POST \
	-d @swagger_upload.json \
	-H "Content-Type: application/json" \
	http://localhost:80/publish

Volume

In order to publish the Swagger Spec via filesystem, mount the directory containing the swagger.json as a volume at /swaggerui/swagger:

docker run --name swaggerui -p 80:8080 -v /path/to/spec:/swaggerui/swagger metz/swaggerui

Persistence

Mounting the volume also preserves the Swagger Spec across container shutdown and startup.
