Dell M1000e gRPC Proxy
|
||||
======================
|
||||
|
||||
Cursedness level: 6.5/10 (regexp XML parsing, JSONP scraping, limited sessions).
|
||||
|
||||
This is a small gRPC proxy to allow programmatic access to a Dell M1000e Chassis Management Controller. It's based on scraping the web interface, as the alternative (WSMAN) is even more ridiculous.
|
||||
|
||||
Functionality
|
||||
-------------
|
||||
|
||||
The only feature supported so far is getting information for an iDRAC KVM console. This can be used to run a iDRAC KVM proxy (to be implemented), or the original client.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
./cmc-proxy -h
|
||||
|
||||
Flags are self-explanatory. This is based on [hspki](https://code.hackerspace.pl/q3k/hspki), so you'll need to have compatible (dev) certs to run this. The proxy listens on gRPC and a status HTTP debug server.
|
||||
|
||||
Example
|
||||
-------
|
||||
|
||||
$ grpc-dev -d '{"blade_num": 6}' cmc.q3k.svc.cluster.local:4200 proto.CMCProxy.GetKVMData
