You can automate writing files to disk using the
write_files cloud-config directive.
#cloud-config write_files: - path: /etc/rc.local permissions: "0755" owner: root content: | #!/bin/bash echo "I'm doing things on start"
By default, the
write_files directive will create files in the console container. To write files in other system services, the
container key can be used. For example, the
container key could be used to write to
/etc/ntp.conf in the NTP system service.
#cloud-config write_files: - container: ntp path: /etc/ntp.conf permissions: "0644" owner: root content: | server 0.pool.ntp.org iburst server 1.pool.ntp.org iburst server 2.pool.ntp.org iburst server 3.pool.ntp.org iburst # Allow only time queries, at a limited rate, sending KoD when in excess. # Allow all local queries (IPv4, IPv6) restrict default nomodify nopeer noquery limited kod restrict 127.0.0.1 restrict [::1]
