[IDEA] Replace HAProxy with vulcand

pires opened this issue 10 years ago · 6 comments

It would be great to replace haproxy with vulcand, since governor could re-use data that's already present in etcd.
One of the pros of vulcand is that it doesn't need to reload/restart when configuration changes.

Need this implemented first.

Answer 1 · 2015-03-24T02:11:55.000Z

Does vulcand read etcd at load and run without re-reading the etcd for changes? Or, does it poll etcd for changes?

AFAIK, vulcand subscribes (long-polling) for changes in a number of keys and reloads configuration every time you add/change/remove frontends, backends, etc.

thats something confd can do ... first of all vulvand does not support tcp lbing .. so thats not possilble anyway .. nginx could .. yet haproxy is the far better solution

Answer 4 · 2015-06-01T11:03:46.000Z

confd is just another moving part that exists only because haproxy doesn't allow for frontend/backend management without reloading configuration file. I'm against adding other moving parts as it makes the solution more complex to setup and maintain.

I'm currently working on having TCP support for vulcand.

vulcand has significantly worse performance, upstream development also seems to have paused.

True. Working on that.
