To use Nginx<\/strong> as a Load Balancer<\/strong>, you need to add it to the namespace<\/strong> with the other containers.<\/span> For connectivity, add the following to the "http<\/strong>" block in the nginx.conf<\/strong> configuration file:<\/span><\/span><\/p>\n
\r\n    upstream production {\r\n        server artem-api_production;\r\n    }\r\n\r\n    upstream staging {\r\n    \tserver artem-api_staging;\r\n    }\r\n<\/pre>\n
