Re: [PLUG] Multi host init system?
Hello there, > I have an app that is distributed across a dozen servers. > > There are several processes involved, some with dependencies on > processes running on other servers. > What app would you recommend for starting the whole thing up in an > orderly manner? Is it possible to adjust the pieces of software so that there is no required 'orderly' startup? I ask because--if the application requires synchronized startup of services across multiple machines, then what happens when one of the services (or nodes) early in that dependency chain fails during operation? For example, let's imagine services A through I, each of which must be launched before the subsequent can launch: A -> B -> C -> D -> E -> F -> G -> H -> I Assuming normal, orderly, coordinated startup, great. Now, everything is running. Suppose that service C fails. What happens? Will the application still run? Do D through I need to be restarted (or just D)? If it is possible to adjust the individual services so that each of them can run and retry, fail gracefully, or even fail hard (as fast as possible, please) to contend with dependency issues, I would recommend that. Perhaps you have already addressed that question or are in the (unenviable) position of contending with feature-complete software that is ready for deployment. Since you are in the 10+ node realm, I think I'd also agree with using some sort of configuration management (somebody suggested Ansible). With this many nodes, it's an operational truism that one of them will kick the bucket during your dog's midnight birthday party [0] and you'll want to be able to move the service quickly to another node. Hurrah for the well-worn configuration management tools. This is the modern take on startup script dependencies, just now with more network in-between! Everybody needs more network in-between! Not an easy problem. Anyway, good luck with this conundrum! -Martin [0] Silicon devices sense these moments and cherish destroying our equanimity. -- Martin A.

Re: [PLUG] Multi host init system?
I would be using something simple like Ansible. It isn't a multi-host init system but it will get the job done. You can even have it wait on ports being opened before doing the next item in the startup. There are other option is you want to run these application pieces in docker containers; things like kubernetes and docker swarm. If you could move this to docker you also could use things like coreos and fleet. Fleet is a cluster wide init system. If you want this application resilient to host restarts and the distribution cannot then maybe something else like corosync/pacemaker could be used.
