Lucky Port
Open and close ports on the host firewall.
Usage
port [FLAGS] <SUBCOMMAND>
Subcommands
- open: Open a port on the firewall
- close: Close a port on the firewall
- get-opened: Get the ports opened by this charm
Usage
The lucky port
command allows you to open
, close
, and get-opened
ports on the host firewall.
Note: Juju will not actually expose the opened firewall ports unless the user deploying the charm exposes it using
juju expose my-app
. In this way, apps are not accidentally exposed to the internet without the user meaning to.
Examples
Make sure your configured port is the only port opened:
# Make sure any previously opened ports are closed
$ lucky port close --all
# Open the new ports
$ lucky port open $(lucky get-config listen-port)
