Create http server listening on unix sockets and systemd socket activated fds
Quick Usage
go get go.balki.me/anyhttp
Just replace http.ListenAndServe with anyhttp.ListenAndServe.
- http.ListenAndServe(addr, h)
+ anyhttp.ListenAndServe(addr, h)
Address Syntax
Unix socket
Syntax
unix?path=<socket_path>&mode=<socket file mode>&remove_existing=<yes|no>
Examples
unix?path=relative/path.sock
unix?path=/var/run/app/absolutepath.sock
unix?path=/run/app.sock&mode=600&remove_existing=no
| option | description | default |
|---|---|---|
| path | path to unix socket | Required |
| mode | socket file mode | 666 |
| remove_existing | Whether to remove existing socket file or fail | true |
Systemd Socket activated fd:
Syntax
sysd?idx=<fd index>&name=<fd name>&check_pid=<yes|no>&unset_env=<yes|no>&idle_timeout=<duration>
Only one of idx or name has to be set
Examples:
# First (or only) socket fd passed to app
sysd?idx=0
# Socket with FileDescriptorName
sysd?name=myapp
# Using default name and auto shutdown if no requests received in last 30 minutes
sysd?name=myapp.socket&idle_timeout=30m
| option | description | default |
|---|---|---|
| name | Name configured via FileDescriptorName or socket file name | Required |
| idx | FD Index. Actual fd num will be 3 + idx | Required |
| idle_timeout | time to wait before shutdown. syntax | no auto shutdown |
| check_pid | Check process PID matches LISTEN_PID | true |
| unset_env | Unsets the LISTEN* environment variables, so they don't get passed to any child processes | true |
TCP
If the address is not one of above, it is assumed to be tcp and passed to http.ListenAndServe.
Examples:
:http
:8888
127.0.0.1:8080
