The 'tailscale serve' set of commands allows you to serve
|
||||
content and local servers from your Tailscale node to
|
||||
your tailnet.
|
||||
|
||||
You can also choose to enable the Tailscale Funnel with:
|
||||
'tailscale serve funnel on'. Funnel allows you to publish
|
||||
a 'tailscale serve' server publicly, open to the entire
|
||||
internet. See https://tailscale.com/funnel.
|
||||
|
||||
EXAMPLES
|
||||
- To proxy requests to a web server at 127.0.0.1:3000:
|
||||
$ tailscale serve / proxy 3000
|
||||
|
||||
- To serve a single file or a directory of files:
|
||||
$ tailscale serve / path /home/alice/blog/index.html
|
||||
$ tailscale serve /images/ path /home/alice/blog/images
|
||||
|
||||
- To serve simple static text:
|

$ tailscale serve / text "Hello, world!"
