Use the Redoc Docker image	/docs/quickstart/docker/

How to use the Redoc Docker image

Redoc is available as a pre-built Docker image in Docker Hub.

If you have Docker installed, pull the image with the following command:

docker pull redocly/redoc

Then run the image with the following command:

docker run -p 8080:80 redocly/redoc

The preview starts on port 8080, based on the port used in the command, and can be accessed at http://localhost:8080. To exit the preview, use control+C.

By default Redoc starts with a demo Swagger Petstore OpenAPI definition located at http://petstore.swagger.io/v2/swagger.json. You can update this URL using the environment variable SPEC_URL.

For example:

docker run -p 8080:80 -e SPEC_URL=https://api.example.com/openapi.json redocly/redoc

Create a Dockerfile

You can also create a Dockerfile with some predefined environment variables. Check out a sample Dockerfile in our code repo.
