Servox

Enhanced

- The `port` option is now respected by the sidecar injection remedy.
- Introduced the `scripts` connector that supports attaching arbitrary shell
commands to be run before, on, or after an event is dispatched by the servo. [245](https://github.com/opsani/servox/pull/225)
- Add ImagePullBackOff error for target service (tuning or mainline) [248](https://github.com/opsani/servox/pull/248)
- Improve K8s Deployment updates and error handling. [253](https://github.com/opsani/servox/pull/253)

Fixed

- Dynamically named ports are now supported by resolving the port name against
the Pod spec template [246](https://gihtub.com/opsani/servox/pull/246)
- Use correct process for determining current active pods [247](https://gihtub.com/opsani/servox/pull/247)
- Support settlement command correctly in ServoX k8s connector [240](https://gihtub.com/opsani/servox/pull/240)
- Remove token exposure in TRACE log [239](https://gihtub.com/opsani/servox/pull/239)
- When checks fail and are rerun, the tuning pod is no longer rebuilt
unnecessarily.
- Eliminated cases where the `KubernetesConnector` could fail to report progress
due to Kubernetes API availability, timeouts, etc. resulting in errant Servo
disconnected events being emitted by the optimizer.
- Improved test resiliancy and removed name collisions in automated test namespaces

Fixed

- Port was not being accepted as input on inject_sidecar cli command [241](https://gihtub.com/opsani/servox/pull/241)

Enhanced

- Flexible support for pod template resource specifications [182](https://github.com/opsani/servox/pull/182)
- Aligned memory unit display with the expected Kubernetes output

Fixed

- Allowed min=max in range settings
- Correctly use selector labels to locate deployment [202](https://github.com/opsani/servox/pull/202)

Enhanced

- Opsani Dev checks for traffic flows are faster.
- Service check errors now include the missing labels.
- Container resources are now checked against the optimizable range before
optimization begins.
- Introduced pub/sub transformers for filtering, splitting, and aggregating
messages across channels. [191](https://github.com/opsani/servox/pull/191)
- Added `--no-poll` and `--interactive` options to the `servo run` command.
[192](https://github.com/opsani/servox/pull/192)
- Enjoy a random start-up banner in a random color palette.
[193](https://github.com/opsani/servox/pull/193)
- `TRACE` logging from the `servo.api` module now includes cURL commands.
[194](https://github.com/opsani/servox/pull/194)

Fixed

- Traffic checks no longer require a 2xx status code to pass.
- Load testing hints using Vegeta now include `kubectl exec` stanza to run
remotely rather than on the local workstation.
- Resource requirements now output a sensible error message rather than raising
a `KeyError` when `cpu` or `memory` are not defined.

Changed

- Updated to httpx v0.17.0
- Updated uvloop to v0.15.2
- Optimizer is now a member of the Configuration object.

Fixed

- HTTP connection errors could result in unbound references to `response` in the
`servo.api` module. (SOL-292)

Enhanced

- Added support for deploying Opsani Dev on Kubernetes `NodePort` Services.
- Range setting that are out of step alignment now suggest alternative values
to consider.
- Normal operational logging is less verbose.

Fixed

- Container restarts due to `CancellationError` in response to Kubernetes
adjustment failures are now avoided.
- Kubernetes `ContainersNotReady` status upon timeout are now handled as
adjustment failures.
- HTTP status code 4xx responses are no longer retried.
