High-Availability does not appear to share state when logging in about onpremises HOT 10 CLOSED

Confirmed working. Awesome! Thanks!

https://structurizr.com/help/on-premises/faq doesn't provide any additional information.

I imagine the problem is the round-robin load balancer. Short term, you'll either need to configure sticky sessions instead, or setup session replication/clustering in Apache Tomcat (assuming you're using that). Longer term, we could add a way to configure session state to be stored outside the web server (e.g. in Redis), but that's not available at the moment.

from onpremises.

Would it be possible to document this? My understanding of high-availability is that sessions won't be bound to single instance of the server, so I would at least state that caveat in any documentation of HA.

I've added support for storing HTTP sessions in Redis, which is available in the latest version of the on-premises installation, and this should provide a way to share session information across pods when using a round-robin load balancer. See https://structurizr.com/share/18571/documentation#http-sessions for more details.

Excellent work! Which release is this in?

It really says a lot about your group when you can accomplish this kind of improvement. Kudos, really!

Thanks, you're welcome. 2860 onwards -> https://structurizr.com/help/changelog

I integrated this change, but it appears that using a Redis password is mandatory. This makes local development more difficult as you have to then wire in a config into the container with a password (no easy env var). Is it possible to remove that restriction?

from onpremises.

Just leaving the password empty should work:

structurizr.redis.password=

Ah I tried structurizr.redis.password="". I'll try again in a bit.
