⁠nginx-subdomain-proxy

https://github.com/hirokiky/nginx-subdomain-proxy⁠

Nginx container to pass requests to another host with same sub domain.

If you specify

• example.local as "from host"
• example.com as "to host"

This nginx container will pass all requests like this

*.example.local => *.example.com

⁠Why nginx-subdomain-proxy

It's useful to create proxy server for inner Web services (like *.mydomain.private). If you run inner services in AWS VPC and want to access from out of the VPC for debugging, Just you need launch this container with *.mydomain.com as "from host" and *mydomain.private as "to host".

                          VPC
                          +-------------------------------------------+
                          |                                           |
[Web] *.mydomain.com--> proxy -> *.mydomain.private [inner services]  |
                          |                                           |
                          +-------------------------------------------+

⁠How to use

You can run this container without inheriting Dockerfile, just specify these arguments.

• FROM_HOST_REGEXP: A regexp for "from host" like (mydomain\.com)
• TO_HOST: string for "to host" (mydomain.private)
• RESOLVER_IP: IP address for DNS server. If you use privete Route53 within AWS VPC, specify *.*.*.2 value in your VPC IP range.

and you need to mount /var/run/docker.sock at /tmp/docker.sock in the container.

⁠Example

sudo docker run -e "FROM_HOST_REGEXP=mydomain\.com" -e "TO_HOST=mydomain.private" -e "RESOLVER_IP=8.8.8.8" -v /var/run/docker.sock:/tmp/docker.sock -p 80:80 hirokiky/nginx-subdomain-proxy
