Is HA possible?

[dberardo-com]

Is your feature request related to a problem? Please describe.

I am not familiar to where the nodered stores information but i see a "replicaCount" attribute for this chart, so i wonder:

• is high-availability possible with this chart?
• how can applications/flows be deduplicated if replicaCount is > 1 ? is there a way to let them run only once?
• is possible to achieve HA saving information in an external HA-database cluster?

regards

Hi @dberardo-com,

thanks for posting the issue. Currently the chart does not support an HA setup of node-red.

We should possible make the replicaCount not configurable to avoid any confusions.

Hi @dberardo-com,

With https://github.com/SchwarzIT/node-red-chart/pull/180, we going to remove the option to configure the replicaCount to avoid any misunderstanding regarding a possible HA option of this Helm Chart.

ok thanks, i assume that HA is in general not possible in node-red, regardless of this helm chart right ? just to confirm
