v0.12.9

Announcing Akri v0.12.9!

Akri v0.12.9 is a pre-release of Akri.

To find out more about Akri, check out our documentation and start
contributing today!

New Features

The v0.12.9 release contains the following changes:

1. Configuration-level resource support (#627). This implements the proposal of exposing resources at the Configuration level. This allows users to select resources to use at the configuration-level without having know the instance ID beforehand.
2. Support discoveryProperties in the Configuration (#619). This implements the proposal for allowing users to specify credential data through the discoveryProperties section in the configuration. The Agent can read these properties and pass them to the discovery handlers for discovering authenticated devices. This provides a native K8s experience by supporting K8s Secrets and K8s configMaps.
3. Enable ONVIF discovery handler and broker to discover and access authenticated devices (#638, #646). This allows the ONVIF discovery handler to discover IP cameras and other ONVIF devices that require authentication. Once authenticated devices are discovered using the credential data passed through, the broker can also access the data from these devices using the device UUID to look up credentials from the credential directories and authenticate the device.

Fixes, features, and optimizations

• opt: Improve udev testability and tests (#582)
• opt: Generate a self-signed certificate for webhook if none given in Helm (#588)
• fix: Update env_logger and clap to fix RUSTSEC-2021-0145 (#590)
• opt: Add protobuf-compiler to crossbuild intermediate containers (#594)
• opt: Add K8s 1.27 to test cases and remove 1.23 (#595)
• fix: Fix intermediate dotnet openCV image build (#596)
• opt: Force all Akri components to use the Linux node selector (#599)
• fix: Fix possible crash when modifying Configuration (#602)
• fix: Upgrade Docker images from Debian Buster to Bullseye (#606, #607, #609)
• fix: Fix discovery channels being stopped when Configurations are modified or deleted (#612)
• fix: Stop the controller from panicking when unable to create pod and output log instead (#615)
• fix: Correct ONVIF filtering (IP address, MAC address, scopes) (#622)
• opt: Revamp E2E test suite (#623)
• feat: Add udev E2E tests (#637)
• fix: Return discovered devices that fails to get IP/MAC address if IP/MAC filters are not used (#640)
• feat: Add UUID filter to ONVIF discovery handler (#641)
• opt: Remove unused Rust dependencies (#653)
• fix: Correct Agent's behavior on Instance deletion (#654)
• fix: Update dependencies of sample applications to fix security vulnerability (#660)

View the full change log

Breaking Changes

1. With the ONVIF discovery handler using UUID_serviceUrl as the device ID this changes the hash ID in the Akri instance of the discovered camera. Now, the ONVIF discovery handler always exposes the device UUID in device properties.
2. With the IP/MAC address filtering in device properties becoming optional, the ONVIF discovery handler only expose the IP/MAC addresses when it is able to get them from the device. Retrieving the IP/MAC address requires credentials, so if none are provided, the discovery handler reports the devices without exposing the IP/MAC addresses in properties.

v0.10.4

Announcing Akri v0.10.4!

Akri v0.10.4 is a pre-release of Akri.

To find out more about Akri, check out our documentation and start
contributing today!

New Features

The v0.10.4 release contains the following changes:

1. Enable mounting connectivity information for multiple devices/instances in a Pod (#560 , #561). Previously, Akri could only mount one device property per discovery handler to a Pod as all devices of the same discovery handler had the same environment variable name. This release fixes this issue by appending the instance hash to the environment variable name and slot ID to the annotation key name. This is a breaking change as it changes the way brokers look up properties.
2. Enable udev discovery handler to discover multiple node devices (#564). Akri now allows udev discovery handler to group devices that share a parent/child relation.
3. Mount udev devpath in Akri brokers (#534). This enables discovering udev devices without a devnode by using devpath instead. This is a breaking change in the udev discovery handler as it changes the way Akri creates instance ids for udev devices.
4. Mount udev devices through DeviceSpec instead of Mounts (#576). This switches from using Mounts to using DeviceSpec for device nodes, and exposes the desired permissions to non priviledged containers.

Fixes, features, and optimizations

• feat: Add nodeSelectors for Akri agent (#536)
• fix: Fix wrong indentation on udev-configuration.yaml for securityContext (#538)
• fix: ListAndWatch only sends device if the list has changed (#540)
• fix: Use tokio::sync::RwLock instead of tokio::sync::Mutex (#541)
• opt: Upgrade Ubuntu agent version (#546)
• opt: Added more securityContext to ensure Helm templates use the most restrictive setting (#547)
• opt: Update nodejs actions to node16 (#548)
• fix: Set pre_start_required to false in get_device_plugin_options (#554)
• fix: Modify Agent to reduce frequency of Pods getting UnexpectedAdmissionError (#556)
• fix: Specify crictl container runtime in e2e test workflow (#559)
• fix: Suffix usage slot to annotation key name (#560)
• fix: Added udev devnode to device mounts instead of devpath (#562)
• fix: Fixed watch crash API unreachable (#568)
• fix: Verify DiscoveryURL from OPC Server is resolvable (#570)
• opt: Update kubernetes versions in e2e test (#573)
• opt: Update rust to 1.68.1 and tarpaulin to 0.25.1 (#574)
• opt: Upgrade Rust CI actions to maintained ones (#581)
• opt: Update warp dependency to fix RUSTSEC-2023-0028 (#585)

View the full change log

Breaking Changes

1. With enable mounting connectivity information for multiple devices/instances in a Pod, Akri now changes the name of the device properties from DEVICE_DESCRIPTION to DEVICE_DESCRIPTION_INSTANCE_HASH to allow multiple device properties of the same discovery handler to be injected to the same broker. For example, a broker can look up the Akri instance akri-debug-echo-foo-8120fe by the environment variable DEBUG_ECHO_DESCRIPTION_8120FE instead of DEBUG_ECHO_DESCRIPTION.
2. With mount udev devpath in Akri broker, Akri changes the way it creates udev Akri instance id from using the hash of devnode to using the hash of devpath

v0.8.4

Announcing Akri v0.8.4!

Akri v0.8.4 is a pre-release of Akri.

To find out more about Akri, check out our documentation and start
contributing today!

New Features

The v0.8.4 release contains the following major changes:

1. Support for Kubernetes Job brokers (#437). Now Akri has support for deploying Jobs to devices discovered by the Akri Agent. Previously, Akri only supported deploying Pods that were not intended to terminate (and would be restarted if they did). Adding Jobs enables more device use scenarios. More background can be found in the Jobs proposal. This is a breaking change as it required changes to Akri's Configuration CRD.
2. Fix to re-enable applying multiple Configurations that use the same Discovery Handler (#432). This adds back functionality that was removed in v0.6.5 when enabling Akri's new extensibility model.
3. Akri depends on crictl to track whether Pods deployed by the Akri Controller are still running. This release adds new functionality (#418) such that crictl is pre-installed in the Agent container so that it does not need to be installed on each node.

Fixes, features, and optimizations

• fix: Make debug echo capacity configurable (#419)
• fix: Return okay if get 404 when trying to delete an Instance (#420)
• opt: Update .NET dependencies, removing vulnerabilities and reducing size (#422)
• feat: Execute test workloads based on labels instead of flags in PR titles (#426)
• opt: Set K8s distribution with Helm to simplify choosing container runtime socket (#427)
• fix: Fix all clippy errors and update dependency versions (#442)

v0.6.5

v0.6.5

Announcing Akri v0.6.5!

Akri v0.6.5 is a pre-release of Akri.

To find out more about Akri, check out our README and start contributing today!

New Features

The v0.6.5 release introduces Akri's Logo, new features such as a new extensibility model for Discovery Handlers and a Configuration validating webhook, DevOps improvements, and more.

New Discovery Handler extensibility model

• feat: Discovery Handlers now live behind a gRPC interface (#252), so Discovery Handlers can be written in any language without forking Akri and working within its code. See the [Discovery Handler development document] to get started creating a Discovery Handler.
• feat: Support of both default "slim" and old "full" Agent images (#279). Prior to this release, the Agent contained udev, ONVIF, and OPC UA Discovery Handlers. As of this release, Akri is moving towards a default of having no embedded Discovery Handlers in the Agent; rather, the desired Discovery Handlers can be deployed separately using Akri's Helm chart. This decreases the attack surface of the Agent and will keep it from exponential growth as new Discovery Handlers are continually supported. Discovery Handlers written in Rust can be conditionally compiled into the Agent -- reference the development documentation for more details. For the time being, Akri will continue to support a an Agent image with udev, ONVIF, and OPC UA Discovery Handlers. It will be used if agent.full=true is set when installing Akri's Helm chart.

Breaking Changes

Akri's Configuration and Instance CRDs were modified. The old version of the CRDs should be deleted with kubectl delete instances.akri.sh configurations.akri.sh, and the new ones will be applied with a new Akri Helm installation.

• Akri's Configuration CRD's protocol field was replaced with discoveryHandler in order to fit Akri's new Discovery Handler extensibility model and make the Configuration no longer strongly tied to Discovery Handlers. It's unused units field was removed and properties was renamed brokerProperties to be more descriptive.
• Akri's Instance CRD's unused rbac field was removed and metadate was renamed brokerProperties to be more descriptive and aligned with the Configuration CRD.

Significant changes were made to Akri's Helm chart. Consult the latest user guide and Configurations documentation.

By default, the Agent contains no Discovery Handlers. To deploy Discovery Handlers, they must be explicitly enabled in Akri's Helm chart.
