• Generate ssh key for fleetui

    ssh-keygen -f /home/core/.ssh/id_rsa_fleetui -t rsa -C "fleetui@example.com"
  

• Add the public key to /home/core/.ssh/authorized_keys.d

    cp /home/core/.ssh/id_rsa_fleetui.pub /home/core/.ssh/authorized_keys.d
    sudo /usr/bin/update-ssh-keys
  

• Docker options

•   # env for fleet-ui
    BUILDER_IMAGE=xuwang/docker-fleetui-builder
    FLEETUI_IMAGE=fleet-ui
    OPTS="-p 3000:3000 \
    -v /home/core/.ssh/id_rsa_fleetui:/root/id_rsa"
