how to configure multiple domain (virtual host) and multiple virtual port

I have run your image with command below.

docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro \
    --name my-nginx-proxy --network=mynetwork jwilder/nginx-proxy

my software run in single container and listen on port 81,82

• port 81 designed for domain a.mydomain
• port 82 designed for domain b.mydomain

case 1, I have use these command. It’s work.

docker run -d --network=mynetwork -e VIRTUAL_PORT=81 -e VIRTUAL_HOST=a.mydomain myimage

case 2, I have use these command. It’s work.

docker run -d --network=mynetwork -e VIRTUAL_PORT=82 -e VIRTUAL_HOST=b.mydomain myimage

Question, how to configure for the following situation?

I would like to use port 81 with domain a.mydomain and port 82 with domain b.mydomain in single container.

I have tried with the following command. It 's not work. docker run -d --network=mynetwork -e VIRTUAL_PORT=81,82 -e VIRTUAL_HOST=a.mydomain,b.mydomain myimage

Please help. Thanks you.

@jakata007 @first087: Here is a workaround until a new feature is implemented.

# start the nginx proxy
docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro \
    --name my-nginx-proxy --network=mynetwork jwilder/nginx-proxy

# start the application container, take note that:
# - it is named (so that the proxies below can see it)
# - it does not have anything exposed
docker run -d --network=mynetwork --name myapp application-with-two-ports

# For each port that you want to expose, configure a pseudo container. 
# These only forward to the 'myapp' container above.
# They are additionally labeled for 'nginx-proxy' to pick up on. 
docker run -d --network=mynetwork -e VIRTUAL_PORT=80 -e VIRTUAL_HOST=a.mydomain \
    -e REMOTE_HOST=myapp -e REMOTE_PORT=81 marcnuri/port-forward
docker run -d --network=mynetwork -e VIRTUAL_PORT=80 -e VIRTUAL_HOST=b.mydomain \
    -e REMOTE_HOST=myapp -e REMOTE_PORT=82 marcnuri/port-forward

Disclaimer: The image for proxying isn’t mine, I haven’t tested this. If for some reason you don’t trust random images, you can always build it from the Dockerfile or make your own image. It should contain something like:

CMD socat tcp-listen:$LOCAL_PORT,reuseaddr,fork tcp:$REMOTE_HOST:$REMOTE_PORT

Also, I doubt @jwilder is currently developing new features, see https://github.com/nginx-proxy/nginx-proxy/issues/1304#issuecomment-535290685. So someone would have to make a PR and hope it gets merged.

Many thanks for that workaround @tkw1536 , I was about to setup another registry / nexus just for 1 customer to achieve this.
