Install docker using Docker Tools or native docker if on mac\n2. Verify if docker-compose is installed by running following command else install it.\n\n```\ndocker-compose\n```\n\nRun the build and integration tests for individual components with\n\n```\nmake indexer\n```\n\n\u0026\u0026\n\n```\nmake reader\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fexpediadotcom%2Fhaystack-traces","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fexpediadotcom%2Fhaystack-traces","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fexpediadotcom%2Fhaystack-traces/lists"}
