Release Date: June 30th, 2021

Namer: Lenny Goodell and MIke Johanson (Intel)

The Ireland Release is the 2nd major release and 8th overall community release of EdgeX Foundry.  Note:  Ireland is not backward compatible with any previous releases of EdgeX (versions 1.x)!

...

  • V2 APIs - all new REST endpoints using improved model objects (for request and responses) and improved API URIs,
  • Use of message bus between Device Services and Application Services (Core Data can also subscribe to the sensor readings or be removed if persistence is not necessary)
  • Improved security to include enabling the Consul API through the API Gateway, providing a common means for all services to retrieve secrets from the secret store, and a means for Consul to bootstrap with its ACL system enabled which provides for better protection of the key/value configuration.
  • Simplified Device Profiles
  • Addition of new Device Services (LLRP, GPIO, CoAP, and UART)
  • New Graphical User Interface
  • Removal of a lot of technical debt accumulated over four years (example: port assignments that align with IANA defined dynamic/private port range definition)

Service by Service Significant Feature List

General

  • Upgraded to Go 1.16, Redis to 6.2.4, Consul to 1.9.5, Kong to 2.4.1, Vault to 1.7.2
  • All services had their APIs updated to the new V2 API formats and object models
  • Port assignments were changed for all services to align them with IANA dynamic/private port ranges) in order to avoid conflicts with standard system and service ports
  • Archive/removal of unused services & code (Logging service, MongoDB, Drools Rules Engine)

Core / Supporting Services

  • Core Data is made optional (as an optional subscriber) when using the message bus to send events/readings to application services.
  • Device Profiles were greatly simplified
  • A new graphical user interface (using Angular.js) was added (offering a new Device wizard, data visualization, service status monitoring and more)

Device Services

  • Device Services send event/readings to Application Services via message bus (default) - allowing for better QoS and removing the need for Core Data when persistence is not needed
  • Contribution of new GPIO, CoAP, LLRP and UART Device Services.  These will be upgraded to v2.0 over the summer of 2021.
  • New structured custom configuration capability

Security

  • Secrets provider for all – providing a common means for all services to retrieve secrets from the secret store (ex: Vault)
  • Enable Consul API through API Gateway
  • Secured Consul: Consul is now bootstrapped and started with its ACL system enabled (better authentication/authorization)

Application Services

  • LLRP Inventory App Service (in Go)
  • New structured custom configuration capability
  • New filter functions for ProfileName and SourceName
  • Encryption function use of Secret Provider for encryption key
  • New template for quick start of new custom app service
  • New custom trigger capability for custom app services
  • Multiple message bus subscriptions which enables multiple filter by subscriptions
  • New Context Storage capability (Key Value store on the App Function Context)
  • Export to multiple HTTP endpoints via function chaining
  • URL/PublishTopic placeholder capability (using key/values from Context Storage to replace placeholders in export URL or PublishTopic)
  • Cleaned Up Configuration to include trigger configuration structured better and configurable pipeline that is more concise and consolidated

DevOps

  • Cleaned up Docker image naming/descriptions/archive tagging
  • Cleaned/improved Docker Compose creation and organization
  • Community notifications on build failures
  • Repository Badging – improve adopter comfort
  • Developer Documentation

Test/QA

  • Integration testing (from DS to rules engine checks)
  • Performance testing
