While watching this Inductive University video about redundancy:
How Redundancy Works - Inductive University
I noticed the video explains the redundancy concept, but it skips an important part: how to actually set up two Ignition gateways on the same machine using different ports before configuring redundancy.
I had to figure out myself that:
-
a second Ignition installation is needed
-
each gateway must use different ports
-
separate Gateway Network ports are also required
Example:
-
Gateway 1 → 8088
-
Gateway 2 → 9088
I think showing this setup briefly in the video would make redundancy easier to follow for beginners using a local test environment.
While possibly useful for development, redundancy would never be setup like this in production and I would consider this extremely niche. I think making this known to the general audience via their videos would be more problematic as you would get some people who would run with this in live systems and cause havoc.
Interesting to know, nonetheless!
That makes sense, and I agree this should never be treated as a production redundancy setup.
My point was mainly about the learning experience for people trying to follow the video locally. Since the setup steps for creating two gateways on different ports are skipped, it can be confusing for beginners to understand how the demo environment was prepared before the actual redundancy configuration starts.
A simple “for local testing only” note would probably be enough without encouraging bad production practices.
This is where vms or docker come in though for dev setups
Yeah, that’s true. VMs or Docker definitely make more sense for proper dev/testing setups. I was mostly thinking from the perspective of beginners trying to follow the video quickly on a single machine.
