openstack-tool
==============
Some useful tools for openstack deployment, deployment and operation.
The `deploy` directory contains tools for the deployment, while the `devop` one is for development and operation.
#Deploy
The deployment is based on [RDO](openstack.redhat.com).
##Server configuration
* Managment Network: `192.168.122.0/24`
* Data Network: `10.0.0.0/24`
* Control Node: `10.0.0.100 (eth0)`, `192.168.122.100 (eth1)`
* Compute Node: `10.0.0.101 (eth0)`, `192.168.122.101 (eth1)`
##rdo_install.sh
Install openstack based on RDO and the configuration template.
##rdo_purge.sh
Clear the machine which has openstack installed.
##demo_init.sh
After the installation, init by adding a user and a project with net/subnet/vm.
Recommend to download the [Cirros Image] (https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img) and put it under the deploy directory.
Otherwise the tool will automatically do it.
##demo_clean.sh
Clean the added user, project, vm, net, subnet, etc. by the demo_init.sh.
##havana
Some configuration files for the havana release.
###packstack-answers-gre
RDO configuration template for multinode, GRE based.
###packstack-answers-vlan
RDO configuration template for multinode, Vlan based.
###keystonerc_admin
A reference keystonrc of the admin role.
##icehouse
Some configuration files for the icehouse release.
#Devop
##bashrc
A bashrc template. Please rename this to `.bashrc`, and put in your home directory.
##bash_aliases
Some useful aliases. Please rename this to `.bash_aliases`, and put in your home directory.
##bash_color
Enable colorful bash if supported. Please rename this to `.bash_color`, and put in your home directory.
##ovs_mon
This script can monitor multiple OpenvSwitch rules by filtering useful ones and reformat them. It even support colorful output!
Just put it in your local PATH such as /usr/local/bin/. A more powerful tool is [easyOVS] (https://github.com/yeasy/easyOVS).
The original way to observe the rules in a switch (e.g., s1) is using ovs-ofctl, while it's hard to explore when there're lots of rules
```
$ sudo ovs-ofctl dump-flows s1
NXST_FLOW reply (xid=0x4):

cookie=0x0, duration=294.448s, table=0, n_packets=0, n_bytes=0, priority=800 actions=drop
cookie=0x0, duration=294.454s, table=0, n_packets=0, n_bytes=0, priority=2400,ip,nw_proto=2 actions=CONTROLLER:65535
```
Use ovs_mon, it is easy to watch multiple switches simultaneously, and only output 'useful' rules:
```
$ ovsm s1 s2 s3
###s1
2400 PKT=8 dl_type=0x88cc ACT=CONTROLLER:65535
###s2
2400 PKT=5 dl_type=0x88cc ACT=CONTROLLER:65535
2400 PKT=2 dl_dst=ff::ff ACT=CONTROLLER:65535
2400 PKT=18 arp ACT=CONTROLLER:65535
1401 PKT=1 ip,dl_src=00::02,nw_src=10.0.0.2 ACT=CONTROLLER:65535
1401 PKT=1 ip,dl_src=00::01,nw_src=10.0.0.1 ACT=CONTROLLER:65535
###s3
2400 PKT=5 dl_type=0x88cc ACT=CONTROLLER:65535
```
##ovs_delflow
This tool support specifically del a flow from ovs. The flow can be given with priority and actions, e.g., `priority=100,ip actions=OUTPUT:1`, or `priority=100 ip,nw_proto=2 actions=OUTPUT:2`.
##nss
This script will show all ip address inside each network namespace created inside openstack node.
If give a parameter, then it will show the network namespace containing the key.
```
$ nss 10.0.3.3
