*OpenStack Imaging Hot Sauce* ---- Description Modular image builder from imaging awesomness. ---- Default modules 1. add_user (adds a given set of sudo users) 2. install_rpms (installs a list of rpm packages) 3. Your imagination... ---- Examples $ sudo python ./build.py -s 4G To add users make a yaml like the following: $ cat build.yaml --- # Which modules should be ran (in order) modules: - install-rpms - add_user # Enable this if you wish to install # any users info into the image (ie for testing). add_users: - harlowja ... Then run: $ sudo python ./build.py -s 4G -o blah.tar.gz -x ---- Adding your own module To add your own module create a file in the `modules` folder with a function of the following format: def modify(name, root, cfg): # DO SOMETHING HERE The name that is passed in will be the module name (from configuration) with the root variable being the root directory of the mounted image (useful for chroot) or other file alterations and the cfg variable will be the build configuration dictionary (useful for extracting any module configuration specifics) Then save this file with a given name, ie xyz.py, and then to get this module to be activated add it to the modules list in the build.yaml with the name xyz and then go ahead and build your image. If this module errors out the image will not be successfully built so use this method to stop image building (ie by throwing exceptions) ---- Using your image To upload this image, take the upload-img tool in anvil and provide it the url of your file, for example given a archive at /homes/harlowja/blah.tar.gz you would upload this via the following command. $ python tools/upload-img.py -u file://///homes/harlowja/blah.tar.gz Then the upload-img tool will go through the nitty gritty of extracting that image and connecting the pieces together to form a useable image in openstack. The image produced should also be easily useable in amazon (if someone ever gets around to trying that).
