My goal is to organize the port that dgraph use. Thanks… ---

You can use the `--port_offset` flag to set some port that you want. It will always offset the internal-gRPC, external-gRPC, and HTTP ports by 100. For example: - Alpha with `--port_offset=0` would bind ports 7080, 8080, and 9080. - Alpha with `--port_offset=100` would bind ports 7180, 8180, and 9180. If you need to control the specific ports you expose, you can use the default port mapping and rely on Docker’s port-mapping to map the ports to specific ports, e.g., `docker run -p 11001:7080 ...`. ---

thanks for your reply. I have tried the port\_offset, however, zero gets into the infinity loop. Then, just find out that you need to start zero first then alpha… :). (i am not running the docker) We cannot configure individual port unless we download the source code and change&compile it from [dgraph/x.go at master · dgraph-io/dgraph · GitHub](https://github.com/dgraph-io/dgraph/blob/master/x/x.go) ?

You should be able to configure individual port even without the source code. Can you please share the error logs and the command that you’re using to run `dgraph zero` and `dgraph alpha`? ---

uhm… what’s the option to configure the individual port? as far as i know from dgraph zero/alpha --help, it only provides port\_offset=xxx option to add xxx to those port instead of change individual one. Thank you ---

There’s only the port offset flag. To simplify the config, Dgraph only exposes a single option for an offset. You could use Docker if you have more specific port needs. See the `ports:` field below where the ports are exposed externally as to 12001, 12002, etc. ```auto version: "3.2" services: zero: image: dgraph/dgraph:latest volumes: - type: volume source: dgraph target: /dgraph volume: nocopy: true ports: - 12001:5080 - 12002:6080 restart: on-failure command: dgraph zero --my=zero:5080 alpha: image: dgraph/dgraph:latest volumes: - type: volume source: dgraph target: /dgraph volume: nocopy: true ports: - 11001:8080 - 11002:9080 restart: on-failure command: dgraph alpha --my=alpha:7080 --lru_mb=2048 --zero=zero:5080 ratel: image: dgraph/dgraph:latest ports: - 13001:8000 command: dgraph-ratel volumes: dgraph: ``` ---

thanks… i will keep that in mind if we plan to run in docker, thanks… ---

It seems the `--my` option is not implemented correctly. We are tracking a issue on this. Current recommendation is to use `port_offset` flag. ---

> [@questiondgraph](#): > > thanks… i will keep that in mind if we plan to run in docker, thanks… @questiondgraph - were you ever able to run DGraph locally with your own set of ports? I’m writing a Vue3 web app locally, running on port 8080, and would like it to talk to DGraph locally, but don’t want to run Docker. I keep getting the DGraph infinite error loop no matter what `--port_offset` values I try.
