Fedora OpenStack
Quick Start
Controller:
sudo rbac-playbook hosts/fed-cloud09.cloud.fedoraproject.org.yml
Compute nodes:
sudo rbac-playbook groups/openstack-compute-nodes.yml
Description
If you need to install OpenStack install, either make sure the machine
is clean. Or use ansible.git/files/fedora-cloud/uninstall.sh script to
brute force wipe off.
|
Note
by default, the script does not wipe LVM group with VM, you have to clean them manually. There is commented line in that script. |
On fed-cloud09, remove the file
/etc/packstack_sucessfully_finished to enforce run of packstack and
few other commands.
After that wipe, you have to:
ifdown eth1 configure eth1 to become normal Ethernet with ip yum install openstack-neutron-openvswitch /usr/bin/systemctl restart neutron-ovs-cleanup ifup eth1
Additionally when reprovision OpenStack, all volumes on DellEqualogic
are preserved and you have to manually remove them (or remove them from
OS before it is reprovision). SSH to DellEqualogic (credentials are at
the bottom of /etc/cinder/cinder.conf) and run:
show (to get list of volumes) volume select <volume_name> offline volume delete <volume_name>
Before installing make sure:
make sure rdo repo is enabled
yum install openstack-packstack openstack-packstack-puppet openstack-puppet-modules
vim /usr/lib/python2.7/site-packages/packstack/plugins/dashboard_500.pyand missing parentheses: +
``host_resources.append((ssl_key, 'ssl_ps_server.key'))``
Now you can run playbook:
sudo rbac-playbook hosts/fed-cloud09.cloud.fedoraproject.org.yml
If you run it after wipe (i.e. db has been reset), you have to:
import ssh keys of users (only possible via webUI - RHBZ 1128233
reset user passwords
Compute nodes
Compute node is much easier and is written as role. Use:
vars_files:
- ... SNIP
- /srv/web/infra/ansible/vars/fedora-cloud.yml
- "{{ private }}/files/openstack/passwords.yml"
roles:
... SNIP
- cloud_compute
Define a host variable in inventory/host_vars/FQDN.yml:
compute_private_ip: 172.23.0.10
You should also add IP to vars/fedora-cloud.yml
And when adding new compute node, please update
files/fedora-cloud/hosts
|
Important
When reinstalling make sure you removed all members on Dell Equalogic (credentials are in /etc/cinder/cinder.conf on compute node) otherwise the space will be blocked!!! |
Updates
Our openstack cloud should have updates applied and reboots when the rest of our servers are updated and rebooted. This will cause an outage, please make sure to schedule it.
-
Stop copr-backend process on copr-be.cloud.fedoraproject.org
-
Kill all copr-builder instances.
-
Kill all transient/scratch instances.
-
Update all instances we control. copr, persistent, infrastructure, qa etc.
-
Shutdown all instances
-
Update and reboot fed-cloud09
-
Update and reboot all compute nodes
-
Start up all instances that are shutdown in step 5.
TODO: add commands for above as we know them.
Troubleshooting
-
could not connect to VM? - check your security group, default SG does not:: allow any connection.
-
packstack end up with error, it is likely race condition in puppet - BZ 1135529. Just run it again.
-
- ERROR : append() takes exactly one argument (2 given
-
vi /usr/lib/python2.7/site-packages/packstack/plugins/dashboard_500.pyand add one more surrounding ()
-
- Local ip for ovs agent must be set when tunneling is enabled
-
restart fed-cloud09 or: ssh to fed-cloud09; ifdown eth1; ifup eth1; ifup br-ex
