3.26.0

ECS templates

  • The UDP Gateway Server service has been removed. Historically this service has been used in order to work around various limitations that AWS Network Load Balancer had with UDP traffic. The service is problematic as it runs as a daemon service on each available ECS host machine, and does not support rolling updates. As the support for UDP traffic has improved in the AWS Network Load Balancer, we have decided to remove this service and have UDP traffic be served by the replica Gateway Server service.

Upgrade procedure

  • As this version upgrade removes certain resources, the standard upgrade procedure which follows the template numbering order cannot be followed directly.
  • The configuration of the 5-4-ecs-services template needs to be updated such that the EnableUDPGSRateLimiting and IncludeUDPGatewayServer parameters are set to false. The template does not have to be updated yet, only the configuration. This will remove the UDP Gateway Server service instances.
  • The standard upgrade procedure can commence after the template has been upgraded.
  • While upgrading the 5-4-ecs-services template, consider increasing the number of tasks, or allocated resources, for the Gateway Server service.

3-2-load-balancer-rules

  • The UDP target group target type has been changed from instance to ip.

  • Add NOC rate limiting configuration.

5-4-ecs-services

  • The UDP Gateway Server service has been removed. The UDP traffic will now be served by the existing Gateway Server service.
  • The default NOC Grafana image has been updated to ghcr.io/thethingsindustries/lorawan-stack-noc-grafana:3.26.0.
  • Add NOC rate limiting.

  • UDP Gateway Server references have been removed.

Proxy

  • Fixed routing of "related events" API.

3.15.1

3.15.0

1-2-bastion

  • Added EBSKmsKeyId parameter to choose EBS boot volume encryption key. From now on, EBS boot volumes are encrypted.

2-5-db-timescale

  • Created a hosted zone for internal use
  • This template has been reworked so that updates are now possible. Before updating make a backup of the volume. For more information, please refer to the documentation at https://www.thethingsindustries.com/docs/the-things-stack/host/aws/ecs/updating/#2-5-db-timescale
  • Added EBSKmsKeyId parameter to choose EBS volume encryption key. From now on, EBS volumes are encrypted. Previously only data volume would be encrypted using the default key. Encrypting boot drive does not significantly increase security, and is mainly targeted towards compliance with regulations. If you wish to encrypt your boot drive, please:
    1. Change the ApplicationServerStorageEnabled parameter in 5-2-ocs-ops and 5-4-ecs-services to false.
    2. Create a snapshot of the TimescaleDB EBS volume.
    3. Download your existing 2-5-db-timescale stack template, remove the Instance, StorageVolume, StorageVolumeLifecyclePolicy and VolumeLifecycleRole resources along with the Outputs section. Update the stack, the change set should remove these resources.
    4. Update the 2-5-db-timescale stack with new template to create the EC2 instance and volume again. Do not forget to specify EBS volume snapshot.
    5. Change the ApplicationServerStorageEnabled parameter in 5-2-ocs-ops and 5-4-ecs-services back to true.
    6. For more complex use cases, like changing encryption key, refer to AWS documentation.

4-2-configuration

  • Added ISSupportLink parameter
  • Added UplinkTasksNumConsumers and DownlinkTasksNumConsumers parameters to the Network Server tasks, which allow the number of task consumers to be configured.

Proxy

  • Headers with underscores are now dropped, instead of rejecting the whole request.

Prometheus

  • Upgraded to v2.29.2.

3.14.1

5-4-ecs-services

Proxy

  • Fixed generated is-proxy configuration.
  • Allow more concurrent requests (mostly event streams) to the Console.

Prometheus

  • Added recording rule for JavaScript payload formatters latency metric.

3.14.0

Certain templates have different default values for machine types/memory/CPU in order to better reflect a typical deployment. These changes have no impact on functionalities, and do not affect existing users.

2-1-db-aurora-master

  • Allowed encryption of the Aurora database. In order to encrypt existing database:
    1. Remove the 5-3a-ecs-is-service, 5-2-ecs-ops and 2-2-db-aurora-replica (NOT master) stacks.
    2. Create a snapshot of the database for backup purposes.
    3. Log into the bastion, and perform an SQL dump of the database. Refer to the /usr/bin/db-ro command, which is a bash script, for help how to connect to the database.
