Summary
Public Cloud Edge Interface (PCEI) is implemented based on Edge Multi-Cluster Orchestrator (EMCO). PCEI Release 4 (R4) supports deployment of Public Cloud Edge (PCE) Apps from two Public Clouds (Azure and AWS), deployment of a 3rd-Party Edge (3PE) App (an implementation of ETSI MEC Location API App), as well as the end-to-end operation of the deployed PCE Apps using simulated Low Power Wide Area (LPWA) IoT client

Known Limitations, Issues and Workarounds
System Limitations
- EMCO supports Kubernetes clusters only.
- EMCO UI does not support deletion/modification of projects/services/apps at this time
Known Issues
- PCEI-R4-Issue-01: Azure IoT Edge requires deployment of Custom Kubernetes CRD. Azure IoT Custom CRD deployment by EMCO fails (see manual workaround)
- PCEI-R4-Issue-02: Sometimes App tar files created on a Mac fail to be deployed by EMCO (see workaround)
Workarounds
- For PCEI-R4-Issue-01: Refer to PCEI R4 End-to-End Validation Guide, section "Add Azure CRD to Edge K8S Cluster"
- For PCEI-R4-Issue-02:
- Download PCEI Helm Charts to a Ubuntu or CentOS Host/VM
- Create tar App files on Ubuntu or CentOS Host/VM
- Copy the tar App files to a Mac and use Chrome browser to load tar App files in EMCO UI
- Other workarounds:
- For convenience, the PCEI R4 End-to-End Validation Guide uses a local Docker registry on the EDGE-K8S-2 cluster for AWS GGC and PCEI Location API App images. Any other registry could be used. However, the Helm charts values.yaml file must be updated with the correct repo values for the AWS GGC and PCEI Location API App images.
