Common ports Permalink to " Common ports"
JHipster configures many tools and services, and each of them will likely use one or several ports. Here is a documentation to help understand what each port does, and help in case of a port conflict.
Please note that as per the JHipster Policy 1, the standard port for each technology is used, unless that causes a problem (that should be explained here).
The ports here are listed in order, but the most common questions are for ports 8080, 9000 and 9060.
