Diego v0.1445.0

Changes from v0.1444.0 to v0.1445.0

• Depends on garden-linux-release v0.330.0.
• Depends on etcd-release v20.

Important changes to manifest-generation scripts

As part of story #107891444, the generate-deployment-manifest script now takes flag-based arguments instead of positional ones, and simplifies some of the arguments. The script now takes three required stub arguments, and two optional ones:

• -c: CF deployment manifest file (required)
• -i: IaaS settings stub file (required)
• -p: Property overrides stub file (required)
• -n: Instance-count overrides stub file (optional)
• -v: Release-version stub file (optional)

The additional-jobs stub has been dropped, and the persistent-disk overrides stub content is now merged into the IaaS settings stub file.

Significant changes

Performance tests

• Re-enable the benchmark-bbs tests with a smaller target number of records (in flight)
• As an operator I should be able to configure my database persistent disk

Upgrade stability tests

• As a Diego developer, I expect to run the 'upgrade-from-stable' suite in CI against a new BOSH-Lite instance provisioned on AWS

Bind-mounting downloads

• As a BBS API client, I can specify that my DownloadAction on a Task or DesiredLRP is to be provided via a read-only bind-mount, and updated Diego Cells will respect that (in flight)
• add logging around download action's rate limiting

SSH

• As a CF user, I expect that an SSH session into a CF instance should have same environment that the app process does (in flight)

Manifest generation

• Diego-release generate-deployment-manifest script should specify stubs via flags, not positional arguments
• cloudfoundry-incubator/diego-release #103: Allowed to set filename for $development
• Fix metron_agent spec to disable buffering by default
• cloudfoundry-incubator/diego-release #108: failure output of generate-bosh-lite-manifests is confusing

Logging and Monitoring

• The executor's Monitor step should log on health transitions
• The Diego Health dashboard should display the number of unhealthy cells
