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: |
