Show the lists of sockets to export with show http methods.

HTTP methods could be any string(case insensitive), and starting with - will not allowed.

# allow all methods to / path
/var/run/docker.sock

# allow all except POST, PUT, DELETE with basepath /docker/
/var/run/docker.sock:/docker/:-POST,-PUT,-DELETE

# Only allow GET requests
/var/run/docker.sock:/docker/:GET

# Disable all methods of requests
/var/run/docker.sock:/docker/:-*

sudo ./forward -s '/var/run/docker.sock:/:-POST,-PUT,-DELETE'

If you need multiple ports with multiple sockets than give name before prefix of @.

forward -H [email protected]:8082 -s 'localhost@/var/run/docker.sock'

Use -H and -s more than once to make connections.

forward -H [email protected]:8082 -s 'localhost@/var/run/docker.sock' -H [email protected]:8080 -s 'share@/var/run/docker.sock:/:-POST,-PUT,-DELETE'
