Harbor docker push first path segment in URL cannot contain colon

Question

I have set up harbor behind an nginx reverse-proxy, and when I push docker images to it, I get this error

first path segment in URL cannot contain colon

What could be causing this error? There is no error in nginx or harbor ontainer. Thanks!

Answer 1

I solved this issue by adding the following to my nginx config (the Host header is what made it work, the others are also needed).

proxy_set_header  Host              $http_host;
proxy_set_header  X-Real-IP         $remote_addr;
proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;
proxy_set_header  X-Forwarded-Proto $scheme;
