Quick start

Download latest binary and run a server.

# runs a local server on port 8080
./openapi-mock serve --specification-url https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml

# to test that the server successfully ran
curl 'http://localhost:8080/v1/pets'

Alternatively, you can use Docker image.

# downloads an image
docker pull muonsoft/openapi-mock

# runs a docker container with exported port 8080
docker run -p 8080:8080 -e "OPENAPI_MOCK_SPECIFICATION_URL=https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml" --rm muonsoft/openapi-mock

# to test that the server successfully ran
curl 'http://localhost:8080/v1/pets'

Also, you can use Docker Compose. Example of docker-compose.yml

version: '3.0'

services:
  openapi_mock:
    container_name: openapi_mock
    image: muonsoft/openapi-mock
    environment:
      OPENAPI_MOCK_SPECIFICATION_URL: 'https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml'
    ports:
      - "8080:8080"

To start up a container run command.

docker-compose up -d

If you want to reference a local file in docker compose:

• you must first mount the host dir into container - ./openapi:/etc/openapi
• only then can you reference it

version: '3.0'

services:
  openapi_mock:
    container_name: openapi_mock
    image: muonsoft/openapi-mock
    volumes:
    - ./openapi:/etc/openapi
    environment:
      OPENAPI_MOCK_SPECIFICATION_URL: '/etc/openapi/petstore.yaml'
    ports:
      - "8080:8080"
