Hello,

I doing research now about a build in LoadBalancer Alpine - KVM template. But usually there is old example

Contribution: Vrouter enhacements and load ballancing

Hello, I like to contribute OpenNebula community with my work on virtual routers and load ballancing. This contribution consist of several parts: Updated context scripts for Alpine linux with support for keepalived load ballancing Alpine linux 3.5 qcow2 image ready to use Proposal of changes resp. improvements should be done in OpenNebula 1. Context scripts Updated context scripts can be found on github New features: NAT iptables masquerading enabled by new context var ETHx_VROUTER_GATEWAY …

Some questions:

1. Does it still same apply under version 5.4.x?
2. Does it still require install and setup HaProxy with current lastest template?
3. What advantage for using Alpine - KVM template rather than I setup my own VM with install HaProxy?

Thanks!

Hello, I am author of that Alpine KVM appliance.

Advantages of appliance:
Use virtual routers in HA mode with floating IP

Disadvantages
Use VM contexualization - less flexibility, you can’t add new LB nodes on the fly.
Missing support for LB attributes in oned.
