**Check whether hosts are reachable on certain ports and return result on HTTP**
Its intended purpose is to be a bridge server for services that can only probe container or application health on HTTP. Oh, and it's just a single binary that works everywhere!
## What is this
This tool is a very simple web server that takes requests on HTTP to check
whether they are connectable on a provided port. It returns `200 OK` by default if
the port is connectable and `503 Service Unavailable` if it isn't.
## Installation
Just grab one of the statically linked builds from the [Releases
page](https://github.com/svenstaro/proby/releases) and you're good to go!
## Running
All you have to do to run proby is to just call it:
proby
If you don't like the default interface and port of proby, you can change it like this:
proby -i 127.0.0.1 -p 9000
## Usage
### Basic
This makes proby listen only on the local loopback interface at port 9000.
Example request for checking whether port 1337 is connectable on host example.com:
curl localhost:8080/example:1337
example:1337 is connectable
This will return 200 if it is connectable and 503 if it isn't.
You can also use IPv4s or IPv6s, of course:
curl localhost:8080/8.8.8.8:1337
curl localhost:8080/2001:4860:4860::8888:1337
### Advanced
If you'd like to customize the return codes, you can do so by setting the
request parameters `good` and `bad` like so:
curl localhost:8080/example.com:1337?good=201&bad=401
You can also configure a timeout (in seconds) using:
curl localhost:8080/example.com:1337?timeout=2
The default timeout is one second.
## CLI usage
proby 1.0.2
Sven-Hendrik Haase
Check whether hosts are reachable on certain ports and return result on HTTP
USAGE:
proby [FLAGS] [OPTIONS]
FLAGS:
-h, --help Prints help information
-q, --quiet Be quiet (log nothing)
-V, --version Prints version information
-v, --verbose Be verbose (log data of incoming and outgoing requests). If given twice it will also log the body
data
OPTIONS:
-i, --interfaces ... Interface to bind to [default: 0.0.0.0]
-p, --port Port on which to listen [default: 8080]
## Building
You need a recent stable version of Rust and Cargo installed.
Then just type
cargo build --release
After the build, a binary will appear here: `target/release/proby`.
## Releasing
This is mostly a note for me on how to release this thing:
- `cargo release --dry-run`
- `cargo release`
- Releases will automatically be deployed by Github Actions.
- Docker images will automatically be built by Docker Hub.
- Update AUR package.
