R11 Docker - Double lane

Version 15.1 by Erik Bakker on 2023/09/13 07:27

Service affecting R11 template that improves stability of AWS EFS mounts in running instances when a reconnect to EFS is triggered.

Process
We upgrade in two steps to use the new R11 release of the cloud template. Of these two steps, the intermediate step is non-service affecting, and the final step is service affecting.

Overview
It improves the stability of the AWS EFS mounts in running instances when a reconnect to EFS is triggered.

Updates

  • Updated mount configurations of EFS to adhere to provider's standards.
  • Ubuntu version update including latest security patches.
  • This upgrade is service-affecting, as all instances have to be recreated.

Update Steps

  • Use the intermediate template (non-service affecting) (duration: 10 minutes)
    • This step will upgrade the backup machines hosted in the second Availability Zone in your Cloudslot.
    • The network drive containing the Artemis queue store and your Elastic IPs will remain.
  • Use the final template (non-service affecting) (duration: 10 minutes)
    • This step will update your cloud slot configuration to allow an MQTT broker with failover settings.
  • User actions after applying the final template:
    • Check if all runtimes are reachable by Deploy Architecture.
    • Check if all flows have been installed according to the active release.
    • Check if messages pass through the model by verifying a critical message flow in external systems.
