• docker-compose up -d

fleetctl besorgen (auf dem Server)

• wget https://github.com/fleetdm/fleet/releases/download/fleet-v4.66.0/fleetctl_v4.66.0_linux_amd64.tar.gz
• tar -xvzf fleetctl_v4.66.0_linux_amd64.tar.gz
• cp fleetctl_v4.66.0_linux_amd64/fleetctl /usr/local/sbin/
• fleetctl --version

Paket für die Clients bauen (insecure-Variante)

Die Enroll-Secret gibt’s in der Web-Oberfläche unter

• Hosts → Add Host → Linux (DEB)

• fleetctl package --type=deb --enable-scripts \

 --fleet-url=https://fleet.it113.int:8080 \
 --enroll-secret=gYpHjdyHvQb3/JD1K2NSdnJg4aAqgSH8 \
 --insecure

Erzeugt wird z. B.:

• fleet-osquery_1.41.0_amd64.deb

Debian Paket auf den Clients installieren

• dpkg -i fleet-osquery_1.41.0_amd64.deb
• systemctl status orbit.service

CA auf dem Client einspielen

• cp ca.crt /usr/local/share/ca-certificates/fleet-ca.crt
• update-ca-certificates

Der erste Host ist drin
