Cloud-init files are essentially bootstrap codes, that run before each startup, and can - among others - modify files, set up services, create users, etc. Not all types of droplets support all functionalities of cloud-init, for example CoreOS uses it's own implementation, with a very limited subset of valid values.

With cloud-init, it is also difficult to reconfigure the boot process while you are in the middle of the node's boot process. Ignition is meant to initialize systems, not 

The file cloud-config.yml contains: Containeriza1on considera1ons Exoscale answer: Compute + CoreOS + Docker – Fast provisioning: less than 35 sec – Cloud-­‐Init / Userdata – Tags Pros Auto updates of the OS Very easy migra1on Developers love it – They are free to choose their dependencies and libraries at will Cons Does not solve the State problem – How to store the data, database Young technology, skills are not Below is an example of how to do this cloud-init provisioning. Before you provision any of you cloud configs though, I recommend testing them out by running them through the CoreOS cloud-config validator tool to help identify any potential problems your In Proxmox VE cloud-init images are attached as ISO images via a virtual CDROM drive. In order to start using the cloud-init tab in the Web UI, you'll have to add such a drive. This can be done in the Hardware tab, by clicking the Add button and selecting CloudInit Drive. Afterwards, the options in the cloud-init tab become usable.

# - 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. Because cloud-init is called during the initial boot process, there are no additional steps or required agents to apply your configuration. CoreOS runs cloudinit a few times during the boot process. Right now this happens at each boot, but that functionality may change in the future. The first pass is the OEM cloud-init, which is baked into the image to set up networking and other features required for that provider. Cloud config is the CoreOS version of cloud init (used by OpenStack and AWS) and only implements a subset of cloud init’s functionalities.

My experience with cloud-init on on the similar CoreOS saw me use a lot of journalctl /usr/bin/cloud-init, journalctl --unit cloud-* or just plain old journalctl -xe. – Wesley Aug 19 '20 at 16:51 @Wesley as I am unable to connect via SSH when providing cicustom I cannot retrieve the logs from this case.
