Hi Mike, That is what i am also doing with my "daemon project", bamboo comes close but there are always some features that are missing so I drew inspiration from everyone's comments and whipped up a small project.
https://github.com/ankurcha/haproxy-marathon-manager I am still developing but my idea is very simple. 1. User has a rest api to send application definitions (identified by the marathon app id - thanks bamboo for the inspiration). 2. The user defines the exact template of the haproxy rules (as a moustache.js template - thanks mike/bamboo for the inspiration). *this is probably the only point of difference* 3. Use zookeeper to save the application configurations ( thanks bamboo!). Obviously, this is pretty much as "ALPHA" as it gets but I will be vetting this strategy over the next few days but the theory is to make it as light weight as possible. As always, any comments suggestions are welcome! -- Ankur Chauhan On Tue, Sep 9, 2014 at 11:54 AM, Mike Michel <[email protected]> wrote: > Hi, > > > > i changed the haproxy script so it makes use of haproxys ACL feature.
