Significant changes

IMPORTANT: The rep job template now relies on a post-start script to verify that the rep process is healthy after being started. This feature requires a BOSH director at version 1.3213.0 or later, available in BOSH-release v255.4.

BBS Relational Datastore (Experimental)

• As a Diego operator, I should be able to follow documentation to deploy an HA standalone CF-MySQL cluster on my infrastructure
• As a Diego operator, I should be able to use Postgres as a backing relational store for the Diego BBS (in flight)
• As a Diego operator, I would like the examples/aws boosh-strapping to include subnets for MySQL in each AZ so that I do not have to create them manually
• As a Diego operator, I expect the BBS to recover from catastrophic data loss in the relational store so that the system remains functional (in flight)
• As a Diego operator, I would like the option to use the Postgres instance in the CF deployment as a relational backend for the BBS so that I do not have to deploy a separate deployment (in flight)

Performance Tuning

• The rep BOSH job should give the rep enough time to perform its garden healthcheck when starting up

Garden-RunC Integration

• As a Diego operator, I can follow documentation to understand that when changing an existing Diego deployment to use garden-runc instead of garden-linux, I need to recreate the cell VMs so that I do not have a deployment failure

Component Logging and Metrics

• Cells should emit their UnhealthyCell metric every 30s

Security

• As a Diego operator, I expect all of the processes invoked by diego-release ctl scripts to be run as an unprivileged user so that I am better insulated from security vulnerabilities

Documentation

• The ResolvingTask and DeleteTask methods should be included in the ExternalTaskClient BBS interface (in flight)
• Document the public LRP API and related types on the BBS (in flight)
• Document additional Volume types and fields added with Persi work (in flight)

BOSH job changes

Added post-start script for rep job template.

BOSH property changes

• Add diego.bbs.sql.db_driver: Driver for BBS to use against a SQL store.
