Release notes for Edge-LB version 1.3.1

Edge-LB Service version 1.3.1 was released April 29, 2019.

New features and capabilities

  • Includes Mesos health checks when generating the list of active backends.
  • Provides Edge-LB artifacts as a .dcos package bundle.
  • Updates the SDK version from 0.55.2 to 0.55.4.
  • Updates the HAProxy version to 1.9.4.
  • Improves support for dynamically-allocated frontend ports.
  • Displays the frontend name in the output for the dcos edgelb endpoints command.
  • Improves the stability and scalability for the Edge-LB pool dcos-template and in the mesos-listener program.
  • Provides additional test coverage and other improvements in existing Edge-LB integration tests.

Issues fixed

  • DCOS-45719 - Edge-LB waits for load balanced applications to to be running in a healthy state before routing traffic to them. This change prevents Edge-LB from routing traffic to an application before it completes its startup operations and its first health check.
  • DCOS-47839 - Users can specify the Edge-LB pool frontend using either the name or port setting.
  • DCOS-44077 - The mesos-listener program that communicates with Edge-LB includes improvements to tests coverage and code refactoring.
  • DCOS-51865 - Edge-LB continuous integration has been enhanced through testing and code refactoring.
  • DCOS-48059 - Edge-LB can successfully return the task id and task status for both server and sidecar tasks.
  • DCOS-46502 - Validates regular expressions from user input.
  • DCOS-48132 - The Edge-LB dcos-template monitors and reloads its configuration file to prevent Edge-LB pool updates from generating errors when there are frequent pool changes.

Known issues and limitations

  • Edge-LB currently does not support Strict security mode on DC/OS 1.10, but supports Strict security mode in DC/OS 1.11.

  • The steps provided in the DC/OS 1.10 web interface to uninstall Edge-LB are incorrect. In order to correctly uninstall Edge-LB for any given DC/OS version, please follow the steps in the Edge-LB uninstall documentation.

  • Edge-LB running on a CentOS/RHEL 7.2 node where /var/lib/mesos is formatted with ext4 may have connection issues.

  • If a pool is configured with invalid constraints, that pool will not be properly created and will not respect pool deletion. It must be removed manually.
