Re: haproxy management web service ?

[Ed Young]

Pavlos,

I did mean a web service, but basically what I need is a programmatic way
to manage haproxy, and if it isn't a web service, I can always wrap it with
a web service.

My apologies for my python inexperience, so I need some clarification:
haproxyadmin is a python library that uses the stats socket provided by
haproxy, yes?
haproxytool is a python tool that uses the haproxyadmin library, yes?
haproxyadmin must be installed on the same server as haproxy, yes?
haproxytool must be installed on the same server as haproxy, yes?

Technically its possible bind the stats socked on a tcp port iirc, do 
make sure to either bind it on 127.0.0.1 or firewall it properly.
I have no clue if those admin tools can use tcp connection to perform 
their administration tasks..

[Jeff Palmer]

There is a built in web UI which offers that functionality

https://cbonte.github.io/haproxy-dconv/configuration-1.5.html#stats admin

you can see a demo of it at http://demo.haproxy.org (the demo is
read-only, so you won't see the options to enable/disable backends and
such)

Fyi, Eucalyptus implements AWS ELB api using haproxy as its backend.

Re: haproxy management web service ?

[Jeff Palmer]

Ed,


If you look into the "stats socket"  it has the same functionality as
the web interface.  you can interact with it via shell scripts and
similar.   I use this with ansible to take backends out of haproxy
before doing maintenance or updates.  so that may work for you.

If you are looking for like a restful API or similar,  you are going
to have to use a 3rd party solution as haproxy doesn't have this
capability built in.

I assume you don't mean RESTful API, so I will mention
github.com/unixsurfer/haproxyadmin which is a Python module which
does most of operations supported over the stats socket.
This github.com/unixsurfer/haproxytool is a tool which uses the
mentioned library.

Both are in Python and I have some plans to write a Go API, as a way to
learn Golang, but it can take time before it is ready for public release.

I'm aware of the stats application and have it configured to manually
enable, disable and soft stop/start nodes.

The UI is nice, but what I'm asking about is whether there is an web
service or API to enable/disable/soft stop/start nodes programmatically.

That way when I have a release or some other maintenance, I can do it all
from Jenkins, for example.

Re: haproxy management web service ?

[Ed Young]

Ok, thanks!

I just built and installed socat, and I'll check out haproxyadmin as well.

I've got a few golang irons in the fire for the same reason, so let me know
if you make some progress.

Thanks again.

Re: haproxy management web service ?

[Park, Sang-Min]

That is just one piece of overall software.
So Eucalyptus is  the AWS-compatible private cloud and ELB is the 
implementation of AWS ELB on top of haproxy.
To use it, you need to install Eucalyptus on 1 or multiple machines and haproxy 
will be running inside the VMs.

Depending on your use-case, it may be a good fit or over-kill. For example, 
applications should be running the VMs.
If you have AWS experience and plan to run multiple loadbalancers, then you can 
give it a try.
Eucalyptus covers 100% of ELB APIs, which covers life-cycle management, backend 
registration, SSL, etc.

I'm aware of the stats application and have it configured to manually enable, 
disable and soft stop/start nodes.

The UI is nice, but what I'm asking about is whether there is an web service or 
API to enable/disable/soft stop/start nodes programmatically.

That way when I have a release or some other maintenance, I can do it all from 
Jenkins, for example.
