.. _datasource_alt_cloud: Alt Cloud ========= The datasource altcloud will be used to pick up user data on `RHEVm`_ and `vSphere`_. RHEVm ----- For `RHEVm`_ v3.0 the userdata is injected into the VM using floppy injection via the `RHEVm`_ dashboard "Custom Properties". The format of the Custom Properties entry must be: :: floppyinject=user-data.txt: For example to pass a simple bash script: .. sourcecode:: sh % cat simple_script.bash #!/bin/bash echo "Hello Joe!" >> /tmp/JJV_Joe_out.txt % base64 < simple_script.bash IyEvYmluL2Jhc2gKZWNobyAiSGVsbG8gSm9lISIgPj4gL3RtcC9KSlZfSm9lX291dC50eHQK To pass this example script to cloud-init running in a `RHEVm`_ v3.0 VM set the "Custom Properties" when creating the RHEMv v3.0 VM to: :: floppyinject=user-data.txt:IyEvYmluL2Jhc2gKZWNobyAiSGVsbG8gSm9lISIgPj4gL3RtcC9KSlZfSm9lX291dC50eHQK **NOTE:** The prefix with file name must be: ``floppyinject=user-data.txt:`` It is also possible to launch a `RHEVm`_ v3.0 VM and pass optional user data to it using the Delta Cloud. For more information on Delta Cloud see: http://deltacloud.apache.org vSphere ------- For VMWare's `vSphere`_ the userdata is injected into the VM as an ISO via the cdrom. This can be done using the `vSphere`_ dashboard by connecting an ISO image to the CD/DVD drive. To pass this example script to cloud-init running in a `vSphere`_ VM set the CD/DVD drive when creating the vSphere VM to point to an ISO on the data store. **Note:** The ISO must contain the user data. For example, to pass the same ``simple_script.bash`` to vSphere: Create the ISO ^^^^^^^^^^^^^^ .. sourcecode:: sh % mkdir my-iso NOTE: The file name on the ISO must be: ``user-data.txt`` .. sourcecode:: sh % cp simple_script.bash my-iso/user-data.txt % genisoimage -o user-data.iso -r my-iso Verify the ISO ^^^^^^^^^^^^^^ .. sourcecode:: sh % sudo mkdir /media/vsphere_iso % sudo mount -o loop user-data.iso /media/vsphere_iso % cat /media/vsphere_iso/user-data.txt % sudo umount /media/vsphere_iso Then, launch the `vSphere`_ VM the ISO user-data.iso attached as a CDROM. It is also possible to launch a `vSphere`_ VM and pass optional user data to it using the Delta Cloud.
