collect artisanal kubernetes cluster metrics from rust
Bklyn is a rust interface querying heapster.
Find them here
Bklyn relies on the kubernetes heapster API to query cluster metrics. In order to do so, you will need your cluster username and password as well as a url for heapster. You can resolve this url using kubectl
After authenticating with a kubeternetes cluster, run the following
bash
$ kubectl cluster-info
Inspect the output for the Heapster url.
With those items on hand, you should be on your way with bklyn
```rust extern crate bklyn; extern crate hyper;
use bklyn::{Credentials, Heapster}; use hyper::Client; use std::env;
fn main() { if let (Ok(baseurl), Ok(user), Ok(password)) = ( env::var("HEAPSTERBASEURL"), env::var("HEAPSTERUSER"), env::var("HEAPSTER_PASSWORD") ) { let client = Client::new(); let heapster = Heapster::new( baseurl, &client, Credentials::Basic( user, password ) ); if let Ok(names) = heapster.cluster().metrics().names() { for metric in names { println!( "{:#?} metrics {:#?}", metric, heapster.cluster().metrics().values(metric.clone(), &Default::default()) ); } }
}
} ```
