Terraform Enterprise v202309-1 through v202311-1: Fluent-bit and RabbitMQ health checks are skipped

Problem

When you upgrade to Terraform Enterprise versions v202309-1 through v202311-1, the tfe-admin health-check command may show the Fluent-bit and RabbitMQ health checks as SKIPPED.

Example command output:

$ tfe-admin health-check
checking: Archivist Health Check...|   checks that Archivist is up and healthy|- ✓ PASS
checking: Terraform Enterprise Health Check...|   checks that Terraform Enterprise is up and can communicate with Redis and Postgres|- ✓ PASS
checking: Terraform Enterprise Vault Health Check...|   checks that Terraform Enterprise can connect to Vault and is able to encrypt and decrypt tokens|- ✓ PASS
checking: Fluent Bit Health Check...|   checks that the configure Fluent Bit server is healthy|- SKIPPED 
checking: RabbitMQ Health Check...|   checks that RabbitMQ can be connected to and that we can send and consume messages|- SKIPPED 
checking: Vault Server Health Check...|   checks that the configured Vault Server is healthy|- ✓ PASS  
All checks passed.

Cause

There are two distinct reasons for these skipped health checks:

• RabbitMQ: In Terraform Enterprise v202309-1 and later, the application containers follow a new architecture that no longer uses RabbitMQ. The health check is skipped because the service is not present.
• Fluent-bit: A bug in Terraform Enterprise causes the Fluent-bit health check to be skipped. This issue is resolved in release v202311-1.

Solution

The resolution depends on the specific service:

• RabbitMQ: This is expected behavior for the specified versions. No action is required.
• Fluent-bit: To resolve the skipped health check for Fluent-bit, upgrade your Terraform Enterprise instance to version v202311-1 or a more recent release.
