  • Docker-ssh-agent:

    • wip: use TOML config on buildx to avoid DockerHub rate limits
  • Windows Server 2025 images
• Java 25
  • Temurin supplies JDK 25 early access binaries
  • The infra team is busy with other tasks which are more urgent
    • We should create a task in the helpdesk nonetheless
      • Use subtasks, to use it as a JIRA epic
  • We could nonetheless try to write an updatecli manifest and see if it works before proposing changes
    • Which repositories should we target first?
      • Infra
      • Controller
      • Agents?
  • Why not create a cookbook (Kris and Bruno) in order to log what we had to go through?
• RISC-V
  • Asked to access a RISC-V board (Banana Pi F3) with a recent OS and Docker so we can progress on the assessment of Jenkins on RISC-V

Jenkins agents and controller run on RISC-V (Mango Pi MQ-Pro and MILKV Pioneer), but these boards don’t have Docker

Thinking out loud, could the Java 11 migration be an opportunity to deprecate/remove some old plugins?
