docker-compose up
Alternatively it's possible to run as a docker command:
docker run -p 8080:8080 -e "OPENAPI_MOCK_SPECIFICATION_URL=https://raw.githubusercontent.com/luankevinferreira/areadesenvolvedor-widdershins/master/documentation/source/swagger/swagger_open_banking_apis.yaml" -e "OPENAPI_MOCK_USE_EXAMPLES=if_present" --rm muonsoft/openapi-mock
It's possible to use Docker Playground to run the command and expose the mock through internet.
