Tiny Cloud

The Tiny Cloud bootstrapper performs critical initialization tasks for cloud instances during their first boot. Unlike the more popular and feature-rich cloud-init, Tiny Cloud seeks to do just what is necessary with a small footprint and minimal dependencies.

A direct descendant of tiny-ec2-bootstrap, Tiny Cloud works with multiple cloud providers. Currently, the following are supported:

• AWS (Amazon Web Services)
• Azure (Microsoft Azure)
• GCP (Google Cloud Platform)
• OCI (Oracle Cloud Infrastructure)

Features

The following actions will occur only once, during the initial boot of an instance:

• expand the root filesystem to use all available root device space, during the sysinit runlevel
• set the instance's hostname from instance metadata
• install SSH keys from instance metadata to the cloud user account's authorized_keys file (the user must already exist)
• save the instance user-data to a file, and if it's a script, execute it at the end of the default runlevel

Optional features, which may not be universally necessary:

• manage symlinks from NVMe block devices to /dev/xvd and /dev/sd devices (i.e. AWS Nitro instances)
• manage hotpluggable network interfaces
• sync IMDS-provided secondary IPv4 and IPv6 addresses network interfaces

Also included is a handy imds client script for easy access to an instance's IMDS data.

For more information, see the README.
