With this PR expose API can handle npipe as a protocol which is used in windows to expose socket to named pipe. Following is now working. (Tested with CRC) ``` --- captured from the VM --- $ curl http://host.crc.testing:7777/services/forwarder/all | jq . [ { "local": "127.0.0.1:2222", "remote": "192.168.127.2:22", "protocol": "tcp" }, { "local": "127.0.0.1:9090", "remote": "192.168.127.2:9090", "protocol": "tcp" }, { "local": "\\\\.\\pipe\\crc-podman", "remote": "ssh-tunnel://core@192.168.127.2:22/run/podman/podman.sock?key=C%3A%5CUsers%5Cprkumar%5C.crc%5Cmachines%5Ccrc%5Cid_ecdsa", "protocol": "npipe" } ] \\.\pipe\crc-http - - [23/Feb/2022:10:38:20 +0530] "POST /network/services/forwarder/expose HTTP/1.1" 200 0 INFO Listening on: \\.\pipe\crc-podman > $Env:DOCKER_HOST = "npipe:////./pipe/crc-podman" > .\docker.exe info Client: Context: default Debug Mode: false Server: Containers: 1 Running: 1 Paused: 0 Server Version: 3.4.4 Storage Driver: overlay Backing Filesystem: xfs Supports d_type: true ``` Signed-off-by: Praveen Kumar <kumarpraveen.nitdgp@gmail.com> Signed-off-by: Christophe Fergeau <cfergeau@redhat.com>
