A standalone implementation of some cloud metadata APIs to test VM images against. Note that it is not a complete implementation of the API, at this time.
The following is an example of deploying with Apache:
The following command can be used to deploy (Note that you may have to adjust permissions if needed):
#> echo $USER && pwd
user
/home/user
#> git clone https://github.com/nigelb/standalone-cloud-metadata-api.git
#> mkdir -p /var/www/169.254.169.254/cgi-bin
#> pushd /var/www/169.254.169.254/cgi-bin
#> ln -s /var/user/standalone-cloud-metadata-api/standalone_cloud_api/ec2/ec2_cgi_entrypoint.py ec2_cgi_entrypoint.py
#> ln -s /var/user/standalone-cloud-metadata-api/standalone_cloud_api/openstack/openstack_cgi_entrypoint.py
#> chmod +x *.py
#> popd

SCMA_ENABLE_CGITBif this variable is set toTruethen call cgitb.enable().SCMA_CONFIG_DIRset the location of the config directory.SCMA_PYTHON_PATH_INCLUDEif the standalone-cloud-metadata-api module is not in your python's system packages, set this variable to the location of the module.SCMA_CWD_PYTHON_PATH_INCLUDEif this variable is set toTruethen the current working directory will be set toSCMA_PYTHON_PATH_INCLUDE.
One of the methods used to get the MAC address of the requesting machine is to use the arping command. This command uses RAW sockets and usually needs to be run as root, however permissions to use RAW sockets can be granted with the setcap command:
#root> setcap cap_net_raw+ep `which arping`
