I would like to install Harbor behind Traefik proxy. The problem is, I can not do it with docker-compose because Harbor provides installation script.
The question is, it is still possible to install Harbor behind Traefik proxy?
In theory you can install Harbor behind any proxy, but you must note that Traefik is more then a simple proxy, it is like Load Balancer with some feature that know where your services are.
So depends on your service network architecture, in generally Traefik could not be a problem whether it state in front of Harbor like an Edge Router or a Transparent Proxy. Although it targets to discovery all your services expose by some Orchestrator Solution like Kubernetes and Docker Swarm (Harbor use Compose). You should config it like a "The startup configuration (referred to as the static configuration)":
Finally and sadly I must discourage you to use Harbor behind Traefik proxy is useless, but you can hardly use it.
