Diego v1.9.0

on GitHub

Changes from v1.8.1 to v1.9.0

• Verified with garden-runc-release v1.2.0.
• Verified with garden-windows-bosh-release v0.2.0.
• Verified with etcd-release v95.
• Verified with cf-mysql-release v34.
• Verified with cflinuxfs2-rootfs-release v1.53.0.

IMPORTANT: This version of Diego subtracts the maximum size of the cell's download cache from the advertised disk capacity of the cells in order to guard against cases where the cell VMs actually run out of ephemeral disk space on account of competition from instance and system disk usage. This more conservative advertised capacity may result in an increase in placement errors due to insufficient resources in environments that have relatively small disks provisioned. Operators may still configure this capacity manually via the diego.executor.disk_capacity_mb property.

Significant changes

Container Placement

• As a Diego operator, I expect cells to be able to account for disk usage more accurately so that app instances can start reliably

cfdot

• As a cfdot user, I expect to be able to delete a completed Task
• As a cfdot user, I expect to be able to subscribe to BBS LRP events

Routing

• Add route-emitter routing-table benchmarking to CI
• Increase the number of samples on the route-emitter benchmarks

De-Consuling Locks (Experimental)

• As a CF developer, I expect the auctioneer typically not to be unavailable for longer than 1 second during a rolling BOSH deploy when using relational locks
• As a Diego operator, I expect to be able to opt the auctioneer and BBS into relational-lock mode via minimal manifest-generation arguments

Grootfs Integration

• inigo should use different grootfs store_path for each runner / ginkgo node
• cloudfoundry/diego-release #280: Use garden.privileged_image_plugin if GrootFS is enabled

Test Suites and Tooling

• Investigate how to get the full inigo logs on failures
• Add a job to CI that will fail if pb.go files aren't up to date and block candidate
• We should have an environment in CI with TLS enabled for the BBS SQL configuration
• inigo-mysql flake
• units-common flake
• units-mysql flake
• Investigate flaky units common: locket

Documentation

• cloudfoundry/diego-release #279: Add note for GrootFS and stacks
