CHANGELOG

2024-11-04 - Tiny Cloud v3.0.8

Officially add Makefile targets and flesh out tests for newer cloud modules: hetzner (@hmrodrigues), incus (@ncopa), and scaleway (@hmrodrigues).
cloud-config user-data handler has been fleshed out with a subset of functionality, allowing the use of some common #cloud-config user-data configuration.
alpine-config user-data handler has been reimplemented as an extension of cloud-config, adding management of APK repositories and Alpine autoinstall.
Remove deprecated hotplug modules. nvme-ebs-symlinks has been deprecated since v3.0.0, and imds-net-sync hasn't been supported for AWS since tiny-cloud-network-2.2.2-r0 in Alpine Linux 3.17.
Remove code related to the installation/testing of hotplug modules.

Replace non-functioning tiny-cloud --setup with working --enable and --disable to enable/disable the set of Tiny Cloud init scripts.
Reload user-data if bootstrap is incomplete, even if previous user-data file exists.
Init actions that fail should cause tiny-cloud to also terminate with an error.

Adds support for additional ssh-authorized-keys via userdata for experimental Alpine auto installer.

Tiny Cloud has been reorganized into four init script phases...
- boot - "boot" runlevel, after syslogd is started, and before networking is up.
- early - "default" runlevel, after networking is up, but before user-data is made available. This phase is responsible for pulling in user-data for later phases.
- main - "default" runlevel, after user-data is available. Most things get done here.
- final - "default" runlevel, after all other init scripts have finished. Typically user-data scripts are run here, and bootstrap status is marked as complete.
Tiny Cloud init functionality has been consolidated into /sbin/tiny-cloud and init scripts should use tiny-cloud <phase> to indicate whether boot, early, main, or final actions should be taken.
Use tiny-cloud --setup to add/update Tiny Cloud's init scripts into the right runlevels. Currently only OpenRC is supported.
The example OpenRC init scripts been updated and moved to dist/openrc/.

Tiny Cloud now supports the concept of user-data handlers, to support acting on different payload content-types.
Clouds and user-data handlers can specify their own (or supercede the default) init functions and/or change the init phase in which they are executed. The order of declaration is default --> cloud --> user-data (last one wins).
We now have an experimental alpine installer "cloud", based on NoCloud, and an associated #alpine-config user-data handler, which supports a subset of #cloud-config features, plus some extensions. As this is new, we expect it to experience some continued evolution.
Also thanks to Nataniel Copa (@ncopa), Tiny Cloud now has unit tests.

nvme-ebs-symlinks has been deprecated and disabled by default. The mdev-conf package, as of v4.4 is now responsible for maintaining NVMe device symlinks for AWS.

WARNING: The behavior of mdev-conf is slightly different -- either /dev/sd or /dev/xvd symlinks are created as indicated in NVMe device metadata, but NOT both!

Tiny Cloud configuration has moved to /etc/tiny-cloud.conf.
imds now supports @local-hostname alias. For most clouds this is the same as @hostname.
Fixed setting local-hostname metadata from /proc/cmdline for NoCloud.
