v1.20.1

Release Date: September 23, 2020

Features

• Accessing the RabbitMQ Management UI: You can now access the RabbitMQ Management UI using OAuth2 with a SAML identity provider.

Known Issues

This release has the following known issues:

• Changing the Erlang cookie can cause failed deployments: Changing the Erlang cookie value requires cluster downtime and can result in failed deployments. For more information, see Changing the Erlang Cookie Value Known Issue.

• rabbitmq-server-metrics BOSH job does not provide memory and disk metrics: For on-demand service instances created in v1.20.0 and v1.20.1, the rabbitmq-server-metrics BOSH job does not provide memory and disk metrics. The following error messsage appears in /var/vcap/data/sys/log/service-metrics/rabbitmq-server-metrics.log:

    "source":"rabbitmq-server-metrics","message":"rabbitmq-server-metrics.metrics-fetching-failed","log_level":2,"data":{"error":"GetNode: Error 500 from RabbitMQ: EOF","provider":"APIProvider"}
  

  and the following error message in /var/vcap/data/sys/log/rabbitmq-server/rabbit@<BOSH DNS name>.log:

v1.20.0

Release Date: August 21, 2020

Features

New features in this release:

• Syslog forwarding: Ops Manager now manages Tanzu RabbitMQ syslog configuration. This improvement does not affect syslog configuration for within the tile. However, for new service instances the default program name is different. To learn how to configure syslog to keep the log format consistent, see Configure Syslog Forwarding

• BOSH Hot Swap: To reduce downtime, on-demand service instances created using Tanzu RabbitMQ v1.20 and later use the vm_strategy create-swap-delete. During deployment, IaaS resource usage surges while BOSH creates additional VMs to prepare for the update. You might need to review resource limits for your IaaS and account. If your limits are too low, your deployment fails.
  On-demand service instances that were created using Tanzu RabbitMQ v1.19 or earlier and upgraded to v1.20 or later continue to use the vm_strategy delete-create.
  For more information about how this affects downtime, see BOSH Hot Swap.

• Individual service instance upgrades: Developers can upgrade Tanzu RabbitMQ on-demand service instances individually using the Cloud Foundry Command Line Interface (cf CLI). For more information about this feature, see About Individual Service Instance Upgrades. For instructions for individually upgrading service instances, see Upgrade an Individual Service Instance.

• OAuth: Support for the RabbitMQ OAuth plugin has now arrived in Tanzu RabbitMQ. Users can authenticate with the RabbitMQ Management UI through JWT-encoded OAuth 2.0 access tokens. For more information about the plugin, see rabbitmq-auth-backend-oauth2 in GitHub. For how to enable OAuth in Tanzu RabbitMQ, see Enabling OAuth.

Known Issues

This release has the following known issues:

• The on-demand adapter does not cleanly exit the drain script when the credentials are not present in UAA. The drain script is expected to output an integer to determine success (0) or failure (non-zero). In some cases, the drain script outputs errors even though the operation has succeeded. This causes a failure in the drain operation. This is fixed in v1.20.1.

• Accessing the RabbitMQ Management UI: If you are using OAuth2 with a SAML identity provider, you cannot access the RabbitMQ Management UI. This is fixed in v1.20.1 and later.

• rabbitmq-server-metrics BOSH job does not provide memory and disk metrics: For on-demand service instances created in v1.20.0 and v1.20.1, the rabbitmq-server-metrics BOSH job does not provide memory and disk metrics. The following error messsage appears in /var/vcap/data/sys/log/service-metrics/rabbitmq-server-metrics.log:

    "source":"rabbitmq-server-metrics","message":"rabbitmq-server-metrics.metrics-fetching-failed","log_level":2,"data":{"error":"GetNode: Error 500 from RabbitMQ: EOF","provider":"APIProvider"}
  

  and the following error message in /var/vcap/data/sys/log/rabbitmq-server/rabbit@<BOSH DNS name>.log:

    [error]  CRASH REPORT Process  with 0 neighbours crashed with reason: {function_clause,[]}
  

• Changing the Erlang cookie can cause failed deployments: Changing the Erlang cookie value requires cluster downtime and can result in failed deployments. For more information, see Changing the Erlang Cookie Value Known Issue.
