Sets up and validates policy # creation and execution for: # 1) Identifying VMs connected to a DMZ (currently identified through a # specifically-named security group) # 2) Identifying VMs connected per (1), which are by policy not allowed to be # (currently implemented through an image tag intended to identify images # that are "authorized" i.e. tested and secure, to be DMZ-connected) # 3) Reactively enforce the dmz placement rule by pausing VMs found to be in # violation of the policy. # # Status: this is a work in progress, under test. # # How to use: # Install Congress test server per https://wiki.opnfv.org/copper/academy # # Create Congress policy and resources that exercise policy # $ bash dmz.sh # After test, cleanup # $ bash dmz-clean.sh pass() { echo "Hooray!" } # Use this to trigger fail() at the right places # if [ "$RESULT" == "Test Failed!" ]; then fail; fi fail() { echo "Test Failed!" set +x exit 1 } unclean() { echo "Unclean environment!" fail } if [ $# -eq 1 ]; then if [ $1 == "debug" ]; then set -x #echo on fi fi echo "Activate virtualenv if needed" cd ~/congress/venv source bin/activate source /tmp/copper/admin-openrc.sh echo "Create Congress policy 'test'" if [ $(openstack congress policy show test | awk "/ id / { print \$4 }") ]; then unclean; fi openstack congress policy create test echo "Create dmz_server rule in policy 'test'" openstack congress policy rule create test "dmz_server(x) :- nova:servers(id=x,status='ACTIVE'), neutronv2:ports(id, device_id, status='ACTIVE'), neutronv2:security_group_port_bindings(pid, sg), neutronv2:security_groups(sg,name='dmz')" --name dmz_server echo "Create dmz_placement_error rule in policy 'test'" openstack congress policy rule create test "dmz_placement_error(id) :- nova:servers(id,name,hostId,status,tenant_id,user_id,image,flavor,az,hh), not glancev2:tags(image,'dmz'), dmz_server(id)" --name dmz_placement_error echo "Create image cirros1 with non-dmz image" image=$(openstack image list | awk "/ cirros-0.3.3-x86_64 / { print \$2 }") if [ -z $image ]; then glance --os-image-api-version 1 image-create --name cirros-0.3.3-x86_64 --disk-format qcow2 --location http://download.cirros-cloud.net/0.3.3/cirros-0.3.3-x86_64-disk.img --container-format bare fi echo "Create image cirros2 with dmz image" image=$(openstack image list | awk "/ cirros-0.3.3-x86_64-dmz / { print \$2 }") if [ -z $image ]; then glance --os-image-api-version 1 image-create --name cirros-0.3.3-x86_64-dmz --disk-format qcow2 --location http://download.cirros-cloud.net/0.3.3/cirros-0.3.3-x86_64-disk.img --container-format bare fi echo "Get image ID of cirros dmz image" IMAGE_ID=$(glance image-list | awk "/ cirros-0.3.3-x86_64-dmz / { print \$2 }") echo "Add 'dmz' image tag to the cirros dmz image" glance --os-image-api-version 2 image-tag-update $IMAGE_ID "dmz" echo "Create external network" if [ $(neutron net-list | awk "/ test_public / { print \$2 }") ]; then unclean; fi neutron net-create test_public --router:external=true echo "Create external subnet" neutron subnet-create --disable-dhcp test_public 192.168.10.0/24 echo "Create internal network" if [ $(neutron net-list | awk "/ test_internal / { print \$2 }") ]; then unclean; fi neutron net-create test_internal echo "Create internal subnet" neutron subnet-create test_internal 10.0.0.0/24 --name test_internal --gateway 10.0.0.1 --enable-dhcp --allocation-pool start=10.0.0.2,end=10.0.0.254 --dns-nameserver 8.8.8.8 echo "Create router" if [ $(neutron router-list | awk "/ test_router / { print \$2 }") ]; then unclean; fi neutron router-create test_router echo "Create router gateway" neutron router-gateway-set test_router test_public echo "Add router internal for internal network" neutron router-interface-add test_router subnet=test_internal echo "Wait up to a minute as 'neutron router-interface-add' blocks the neutron-api for some time..." # add a delay since the previous command takes the neutron-api offline for a while (?)
