Eliminate port in the url with nginx

Question

`I want to connect to containers via nginx location blocks without making the port visible in the url for a large scale application my current block is:

location ~"/name/(.*)/(.*)/([0-9])/"{
set port $3;
proxy_pass http://128.0.0.7:$port;
proxy_header Host $host;
}

I want to access the url /name/(.)/(.)/([0-9])/ with this (.*) unique id instead of ([0-9]) port `
