My understanding is that VMware instances use the DatasourceOVF which does support reading ovf configuration from a file inside the image: /var/lib/cloud/seed/ovf/ovf-env.xml Alternatively, you can also use the NoCloud datasource[1] which uses /var/lib/cloud/seed/nocloud-net/ > > My specific question is this: > > If I save a cloud-config .yaml file on the filesystem, is there a way to ask > cloud-init to process and apply it? From a cursory look of the command-line > options and documentation, I don't see how this can be achieved. There are a couple ways, it depends on what sort of config you want to apply. For config modules, one way is: cloud-init --file /path/to/cloud-config.yaml single --name cc_<modulename> --frequency always For network-configuration you really want cloud-init to run during boot as it will read and render config before the Os networking services start. It's pretty straight-forward to use the NoCloud datasource for networking configuration by placing a 'network-config' file in the nocloud-net seed dir; the network-config file format is network-config v1[2] 1. http://cloudinit.readthedocs.io/en/latest/topics/datasources/nocloud.html 2. http://cloudinit.readthedocs.io/en/latest/topics/network-config-format-v1.html#network-config-v1 > > If the above isn't possible, are there any suggestions on how I can implement > this solution? > > thanks > -- > Mailing list: https://launchpad.net/~cloud-init > Post to : [email protected] > Unsubscribe : https://launchpad.net/~cloud-init > More help : https://help.launchpad.net/ListHelp -- Mailing list: https://launchpad.net/~cloud-init Post to : [email protected] Unsubscribe : https://launchpad.net/~cloud-init More help : https://help.launchpad.net/ListHelp
