cf-tunnel

Selfhosting ngrok server/client for running on some tunnel.my.domain should be built with certificates - see references below

Build

Builds docker image for server with CA root certificate for CN=tunnel.my.domain

ca.pem is created in /certs ca.key is printed by docker build - need to save it somethere and mount for next runs to /certs/ca.key

--build-arg NGROK_SERVER_DOMAIN=... is mandatory

docker build --build-arg NGROK_SERVER_DOMAIN=tunnel.my.domain -t codefresh/cf-tunnel:my.domain .

Run server

For all ngrokd parameters see help in docker run -it codefresh/cf-tunnel:my.domain ngrokd -h

Server certificates are generated in /certs/{server.crt,server.key} and signed by ca.pem + ca.key

the command below will start ngrokd -domain $NGROK_SERVER_DOMAIN -tlsCrt certs/server.crt -tlsKey certs/server.key $@

docker run -d -v $(pwd)/ca.key:/certs/ca.key codefresh/cf-tunnel:my.domain server [ngrokd paramams]

Run client

Simplified run - your service will be available from http://myservice.tunnel.my.domain :

docker run -d codefresh/cf-tunnel:my.domain client [myservice.local.address:]8080 myservice[.tunnel.my.domain]

Or run full ngrok command. In this case you need to mount your own config file: docker run -v $(pwd)/ngrok.conf:/root/.ngrok -d codefresh/cf-tunnel:my.domain ngrok [parameters]
