Help! I am running CoreOS and need to add custom cloud-config.
I need to add my cloud-config I cannot find the file or folder in default location as suggested by CoreOS documentations. Currently Linode documentations do not state how to setup
etcd cluster with CoreOS.
Also the documentation states there should be
etcd installed version 3. I can use
etcdctl but cannot find
etcd command. The OS gives error as command not found for
etcd. This is an unexpected behavior.
Kindly help me understand what changes are made in Linode distribution of CoreOS as compared to the stock OS, and also help me understand where can I put the cloud-config file to setup etcd cluster as per my configurations.
You may know that
cloud-init on CoreOS has been deprecated in favor of Ignition, which is what we use to build our CoreOS image at Linode.
Ignition only runs once when the Linode is booted for the first time, and there is no way (currently) for our customers to supply their own ignition file for configuring their CoreOS deploy.
Therefore, in order to setup an
etcd cluster, customers should follow the documentation for reconfiguring an
etcd cluster on the CoreOS website
The documentation gives example
etcdctl commands which customers should be able to use to setup
Thanks a ton, this helped.
CoreOS official documentation is confusing between its versions and frequently deprecated services.
@ktiagha Are there any plans to allow customers to push custom ignition files (or alternatively specify a container-linux-config which gets automatically transpiled into ignition format) while deployment of new nodes in the future (to skip cluster-reconfiguration step) as the old way to do it without reconfiguration is deprecated option from CoreOS(cloud-config)? Would be a greatly appreciated.
