testcloud - download qcow2
cloud images and boot them locally.
[-h, --help] [COMMAND]... [OPTION]... [SUBCOMMAND]... [OPTION]...
testcloud is a small helper script to download and boot cloud images on your machine locally.Currently, only Fedora qcow2 images are supported.
To run testcloud, you need to provide the URL of a cloud image or string in fedora:XX formatto the script which will be used for booting.
If you do not have an image location of your own, you can use oneof the images from the Fedora Cloud download pages at https://alt.fedoraproject.org/cloud/.
Then, testcloud will download the image and save it in the /var/lib/testcloud/backingstores/.It will use this image to create a backing store for a newly created instance which will be placed in/var/tmp/instances/. When the same image has been previously downloaded, testcloud will NOTdownload it again and it will use the current image to create the instance.
When the new instance is created, testcloud will show its IP address that you can use toaccess the running instance via ssh. The login name is fedora and the password ispassw0rd. The IP address of an instance is shown when you list the instance (see COMMANDS).
The instance can also be manipulated and controlled with virt-manager.
The default configuration should work for many people. However, if you need to override thedefault settings, you can do it in the settings.py
file. The example file inconf/settings-example.py
shows the available configuration values which you canalter to suit your needs.
The configuration file must be placed in one of the following locations in order to berecognized.
- conf/settings.py in the git checkout
