Corda 5 Developer Preview 2 is now available.

Prerequisites

Software Prerequisites

Corda 5 DP 2 has been tested with the following:

Software Version
Operating systems
  • Mac OS (intel and ARM)
  • Windows 10/11
  • Linux
  • Java Azul Zulu JDK 11 (Other versions should work but have not been extensively tested.)
    Intellij ~v2021.X.Y community edition
    git ~v2.24.1
    Docker Docker Engine ~v20.X.Y or Docker Desktop ~v3.5.X

    If you want to experiment with multi-worker cluster deployments, you will also need:

    • Kubernetes (incl. kubectl)
    • Helm

    However, Developer Preview 2 focuses on the developer rather than operator experience, so Kubernetes deployments are not required to use Developer Preview 2.

    Required CSDE Ports

    The current version of the Corda combined worker runs on ports 7000, 5432, and 8888. Reserve these ports to avoid errors. For example, some Mac operating systems use port 7000 for the system Control Center. The following section describes how to make the port available.

    Disabling Airplay Receiver on Mac

    You can check if your Mac is using port 7000 for Control Center by running lsof -i :7000 from your terminal. If you see the following results, you must disable Airplay Receiver:

    COMMAND     PID             USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
    ControlCe 18519 <your user name>  32u  IPv4 0x775d695bdd932d5d      0t0  TCP *:afs3-fileserver (LISTEN)
    ControlCe 18519 <your user name>  33u  IPv6 0x775d6960b58a6055      0t0  TCP *:afs3-fileserver (LISTEN)
    

    To disable Airplay Receiver:

    1. Select Sharing in Preferences.
    2. Clear the AirPlay Receiver check box.
      Disabling AirPlay Receiver to unblock port 7000
      AirPlay Receiver in Preferences

    We hope to fix this clash in a future release.
