How to set up Gitlab CE + Gitlab Runner in Docker compose over HTTPS on localhost?

Question

I'm not good at Docker and trying to install the configuration below on my localhost. I know that Gitlab Runner works over https so I've found a solution to use nginx-proxy. Here is my docker-compose.yml. It's not my conf, I just was trying to comment some lines to figure out what is wrong. After docker-compose up --build I get

I added 127.0.0.1 gitlab.my.test to the hosts file. And if I set network_mode: "bridge" to containers, I'll get:
