v4.0.0

Upgraded to support Terraform >= 0.14

v3.8.0

Disk metrics will now only be reported for / instead of all volumes. This reduces the number of metrics pushed to CloudWatch (since the previous behaviour was to include volumes created by Concourse) and saves 💵.

v3.7.0

• Added a new variable secret_cache_enabled (defaults to true) for the ATC which enables the Concourse secret cache. This can provide significant cost savings when using e.g. AWS Secrets Manger or Parameter store as secret backends.

v3.6.0

• Added variable to control CONCOURSE_CONTAINER_PLACEMENT_STRATEGY in ATC module.
• Removed default for name_prefix in ATC module (previously added by mistake).

v3.5.1

• The CloudWatch dashboard will now display maximum CPU usage for the RDS cluster.

v3.5.0

• Replaced awslogs with Amazon CloudWatch agent.
• Instances will now report additional metrics to CloudWatch (memory/swap/disk usage).
• Added the above metrics to the CloudWatch dashboard.

v3.4.0

• Added submodule which creates a minimal CloudWatch dashboard for the Concourse deployment.

v3.3.0

• Fixed health checks not passing for the TSA target group (added the appropriate security group rules).
• Extended test suite to check for passing health checks.

v3.2.0

• Fixed duplicate log entries after enabling logrotate for Concourse.
• Fixed bug where user_data would have a new hash everytime the ref to this module changed. This seems to be fixed by moving templatefile() calls to locals.
• Use user_data_base64 instead of user_data after switching to the cloudinit data source.
• Gzip the user data since we are base64 encoding it anyway.

v3.1.1

Fixed TSA health checks from the network load balancers to target the ATC port instead. This reduces the EOF log entries from failed handshakes by the TSA.
