Rundeck clustering configuration for high availability

[Aviv Oron]

Hi, 

I'm new to Rundeck and I'm trying to setup environment with 2 "master" nodes and couple of "slaves" which will execute the jobs supplied by the masters.

The reason I need this configuration is to prevent single point of failure situation and achieve high availability scheduler for production system.

I could not find any informative solution in the documentation.

Any solution? (rundeck2.0 preferable)

Thanks,

Aviv

Hi Aviv,

Rundeck supports a failover configuration that you can read about here. Depending on your needs there are simpler and more robust methods to keep the service available if the master fails. For failover, it's best to not do any processing on the rundeck servers and to use other nodes to do the work. You might consider those slaves. Let me know if I'm correctly interpreting the question.

Thanks

Hi,

Thanks for the information. 

I already read it but I'm actually looking for more informative examples of how can i configure my system to work with those features.

Will I need to implement it myself over the Rundeck API?

I’ll be glad to know if there a way to get the HA\clustering feature without implement it myself.

If there is – an example of how to configure my servers to work as a cluster will be great.

As I understood from the “Scaling Rundeck” page, this feature is not yet implemented:

 

“The Rundeck project is in its early stages for building a complete HA and clustering solution. We are identifying HA and Clustering requirements and adding them to our roadmap. If these features are important to you we encourage you to vote on them or comment!”

Hi Aviv,

Here's a simple example for failover that covers some of the bases you'll need to configure.

• https://github.com/ahonor/rundeck-vagrant/tree/master/primary-secondary-failover
  

Key configuration points are:

• Shared database (mysql)
  
• Shared logstore (webdav)
  
• Server UUID config for cluster enablement.
  
• Jobs to check status and trigger taking over scheduled jobs
  

This example does not include a front end that proxies requests (eg, like a load balancer) so that is left up to you.

Thanks
