This seems to be in a location that shouldn't be concerned with building.
I'd make this part of the Makefile.

Is the description here correct? 🤔
| go func() { | ||
| errc <- srv.listen() | ||
| }() | ||
|
|
||
| for i := 0; i < defaultRetry && srv.getAddr() == nil; i++ { | ||
| select { | ||
| case err := <-errc: | ||
| return xerrors.Errorf("failed to listen: %v", err) | ||
| case <-time.After(waitRetry): | ||
| } | ||
| } | ||
|
|
||
| srvAddr := srv.getAddr() | ||
| if srvAddr == nil { | ||
| return xerrors.Errorf("failed to start metric server") | ||
| } |

That doesn't solve our problem because we are using an external function to create and start the HTTP server. And we don't want the function to panic with a log.Fatal(server.Serve(ln)) .
- use a make file to build - fixes wrong command description

make build should be enough, now, right?

True, that's explained the line bellow 😄 . I found it interesting to explain a bit the magic behind build-time variables.

Waiting on dedis/dela#209 before merging it. |

Kudos, SonarCloud Quality Gate passed! |
Depends on dedis/dela#209
For now we mainly have Dela metrics. Additional metrics specific to the d-Voting system will be added later.
