Rethink-DB CoreOS cloud-init. GitHub Gist: instantly share code, notes, and snippets. bootcmd is very much like # boothook, but possibly with more friendly. # - bootcmd will run on every boot # - the INSTANCE_ID variable will be set to the current instance id. # - you can use 'cloud-init-per' command to help only run once bootcmd:-echo 192.168.1.130 us.archive.ubuntu.com >> /etc/hosts-[cloud-init-per, once, mymkfs, mkfs, /dev/vdb] You can use cloud-init to install packages and write files, or to configure users and security.

# # "any": If a file system that matches the file system type and device, # then cloud-init will skip the --cloud-init option. The --cloud-init option will tell virt-install to set up a nocloud datasource via a specially formatted .iso file that is generated on the fly, and only used for the first VM bootup. The default behavior when --cloud-init is specified with no suboptions will do the following: Cloud-init allows you to customize a new server installation during its deployment using data supplied in YAML configuration files. This tutorial will briefly introduce one method of utilizing cloud-init when provisioning servers at ProfitBricks. A quick rundown of the procedure we will follow is: Create the customized meta-data and user-data Oftentimes there will be cases where you will want to automate the provisioning and configuration of your Packer bare-metal infrastructure. There are a plethora of tools out there, however, cloud-init is an industry-standard that is used to initialize and configure instances with user-data.

#cloud-config hostname: "wsanderstest1" [etc] I don't see my apache server logging any connections from 10.X.X.X, so the parameter isn't getting passed to cloud-init anyway. Indeed, # journalctl | grep coreos-cloudinit In the absence of a partition table, it will # put it directly on the disk. # # "auto": If a file system that matches the specification in terms of # label, type and device, then cloud-init will skip the creation of # the file system.
