Forward ports from an LXD host to containers. Supports a command line interface as well as a daemon option that can watch as containers spin up and down and adjust port forwarding rules accordingly.
The latest binaries can be downloaded from the releases page or downloaded using
go get github.com/justinjudd/lxd-port-forward
that will also allow you to use the github.com/JustinJudd/lxd-port-forward/forward library in custom code if desired.
The config file format is yaml in the following format and should be saved as config.yaml.
---
container1:
- protocol: tcp
"80": 80
"443": 443
---The above config file would map standard http and https ports from the LXD host to the container with the name container1, where the right-side ports are the ports on the host, and the left-side ports are the ports on the container.
The command line option could then be used as follows.
./lxd-port-forward
to enable the port forwarding rules.
While ./lxd-port-forward -enable=false to tear down the port forwarding rules.
LXD Port Forward can also run in daemon mode by calling ./lxd-port-forward -daemon. It will read the config.yaml file, enable any port forwarding rules for already active containers, and then watch if listed containers are brought up or down, and add or remove port forwarding rules accordingly.
Systemd support can be found in the init subdirectory so that LXD Port Forward can be run as a service.
