Basic OpenStack Testing

Testing coverage example for keystone, glance, neutron, and nova, by Jon-Jozwiak

Validate keystonerc_admin

glance image-create --name "cirros-0.3.2-x86_64" --disk-format qcow2 --container-format bare –-is-public true --file cirros-0.3.2-i386-disk.img
# Enable ping and SSH in default security group 
neutron security-group-rule-create --protocol icmp --direction ingress default 
neutron security-group-rule-create --protocol tcp --port-range-min 22 --port-range-max 22 --direction ingress default

Create a SSH keypair

nova keypair-add testkey > /root/testkey.pem 
chmod 600 /root/testkey.pem
neutron net-create pubnet1 --shared --router:external=True 
neutron subnet-create --name pubsubnet1 --dns-nameserver 157.206.117.226 --allocation-pool start=7.255.26.100,end=7.255.26.150 --gateway 7.255.26.1 --disable-dhcp pubnet1 7.255.26.0/24

Capture IDs

PUBNETID=$(neutron net-list | grep pubnet1 | awk '{print $2}')

Creating Internal L2 private networks

  • Internal-only router to connect multiple L2 networks privately.
neutron net-create privnet1 
neutron subnet-create --name privsubnet1 privnet1 172.16.25.0/24

Capture Net/Subnet UUIDs

PRIVNET1ID=$(neutron net-list | grep privnet1 | awk '{print $2}') 
PRIVSUBNET1ID=$(neutron subnet-list | grep privsubnet1 | awk '{print $2}')

Create router for L3 to connect each network

neutron router-create router1 
neutron router-interface-add router1 $PRIVSUBNET1ID

Set gateway for your external network

neutron router-gateway-set router1 $PUBNETID

Launch an instance…

CIRROSID=$(glance image-list | grep cirros | awk '{print $2}') 
nova boot testserver --flavor 1 --image $CIRROSID --key-name testkey --security-groups default --nic net-id=$PRIVNET1ID
FLOATINGOUTPUT=$(neutron floatingip-create pubnet1)
FLOATINGIP=$(grep floating_ip_address $FLOATINGOUTPUT | awk '{print $4}'
nova add-floating-ip testserver $FLOATINGIP
# Validate connectivity (and that the guest can ping externally)
ssh -i /root/testkey.pem cirros@$FLOATINGIP 'ping -c 5 8.8.8.8'

Clean up the environment after validation

  • optional - but we’re going to test more below
. /root/keystonerc_admin
nova delete testserver
FLOATINGIP=$(neutron floatingip-list | grep 10.81.63 | awk '{print $2}')
neutron floatingip-delete $FLOATINGIP
neutron router-gateway-clear router1
PRIVSUBNET1ID=$(neutron subnet-list | grep privsubnet1 | awk '{print $2}') 
neutron router-interface-delete router1 $PRIVSUBNET1ID 
neutron router-delete router1 
neutron subnet-delete privsubnet1 
neutron net-delete privnet1 
neutron subnet-delete pubsubnet1 
neutron net-delete pubnet1

NOTE THIS DOES NOT CLEAN UP THE SECURITY RULES. SO YOU WON’T NEED TO ADD THEM AGAIN

nova keypair-delete testkey
rm -f /root/testkey.pem

Cinder, Ceilometer, Heat basic validation

Create 1GB cinder volume ‘test3-vol1’ and attach to ‘rhel6-test2’ instance

source ~/keystonerc_user1 
cinder create --display-name test3-vol1 1 
cinder list 
nova list 
nova volume-attach rhel7-test3  auto 
cinder list

Setup the cinder volume on ‘rhel7-test3’ instance

source ~/keystonerc_user1 
ssh -i ~/testkey.pem cloud-user@10.81.63.114
[cloud-user@rhel7-test3 ~]$ sudo su -
[root@rhel7-test3 ~]# fdisk /dev/vdb

Create cinder snapshot of volume ‘test3-vol1’

source ~/keystonerc_user1 
cinder snapshot-create --display-name test3-vol1-snap1 test3-vol1 --force true 
cinder snapshot-list

Clean up cinder volumes and snapshots

cinder snapshot-delete test3-vol1-snap1
nova volume-detach rhel7-test3 dcebde67-6ccf-4d29-a997-09dde6a268c6
cinder delete test3-vol1

Sample Ceilometer data

source ~/keystonerc_user1 
ceilometer sample-list -m image 
ceilometer statistics -m image

Orchestrate WordPress install

using a Heat template Wordpress_Single_Instance.yaml

cat ~/Wordpress_Single_Instance.yaml  (Attached to this email - I think it works but it has been a while...)

Create the stack

heat stack-create -f ~/Wordpress_Single_Instance.yaml -P \
 FloatingNetworkUUID=89725f98-330b-4560-b605-574529329a79 -P \
KeyName=testkey -P DBrootpassword=password wordpress

Validate the stack

heat stack-list
heat event-list wordpress
heat stack-show wordpress

‘stack_status’ should be CREATE_COMPLETE

Find the output value and connect with your web browser. You should see the initial Wordpress Admin page.

Delete your stack

heat stack-delete
