Known Issues

This release has the following known issues:
General
  • Large container deployments may time out if running QEMU without KVM enabled.
  • The only supported virtual disk controller for VMware VMs is IDE; SCSI and SATA are not currently supported.
  • Changes to the system proxy are not propagated into deployed applications. If changing the system proxy settings after deploying applications, the applications need to be stopped and restarted for proxy settings to be propagated into the application.
  • In some cases, a command will fail to execute and the Docker logs will indicate there is a runc issue. When this occurs, resend the command.
OVA
  • When using VMware Fusion 10, switching networks in the host system may cause Predix Edge OS VMs to change their IP address (e.g. 192.168.0.5 to 192.168.0.6).
Raspberry Pi 3 B+
  • Use Predix Edge OS release 2.1.0 for Raspberry Pi 3 B+.
  • Once an imaged SDcard has been used to boot a specific Raspberry Pi board, it cannot be used to boot another board. The MAC address and model are written to the SDcard on first boot; from that point on, the SDcard is unique to that board.
    • E.g., you would encounter this issue if you booted a device, then removed and duplicated that SDcard. Devices running both the original, and all the duplicates, would come up with the same address.
