DevStack in 1 minute
DevStack in 1 minute! Ready, steady, GO!
Install it:
root@devstack:~# git clone https://github.com/openstack-dev/devstack.git |
Almost ready to start, by default DevStack installs 2 mains users:
- admin
- demo
This is how you use the credentials of the user demo:
stack@devstack:~/devstack$ source openrc |
This is how you use the credentials of the user admin:
stack@devstack:~/devstack$ source openrc admin admin |
To go back to the user demo simply do:
stack@devstack:~/devstack$ source openrc demo demo |
Here you go!
Now you can start to use devstack:
stack@devstack:~/devstack$ nova list |
If you want to interact with the services, just remember that DevStack doesn’t use any script init (upstart or service don’t exist). It simply runs the services in a standalone mode (foreground running daemon). To bring up all the services DevStack uses a big parent screen where it encapsulates child screens. This how to access them:
stack@devstack:~/devstack$ ./rejoin-stack.sh |
The good old screen -x <screen-name> works just fine too.
How to navigate through the child screens? Tip ctrl + a + " inside the parent one, you’ll get the general overview:
Num Name Flags
0 shell $
1 key $
2 horizon $
3 g-reg $
4 g-api $
5 n-api $
6 n-cond $
7 n-cpu $
8 n-crt $
9 n-net $
10 n-sch $
11 n-novnc $
12 n-xvnc $
13 n-cauth $
14 n-obj $
15 c-api $

Select one and press enter to get into one child screen. If you want to change the behavior of a daemon, let’s say nova-api, just modify your nova.conf then kill the process in the child n-api with ctrl + c, re-run it (last command) and you’re good.
Other commands like ctrl + a + p (previous) child or n (next child work great too!)
Finally this how to detach the screen ctrl + a + d.
Bonus
As requested, here’s a simple localrc file with the support of Neutron (new code name for Quantum) and all the main projects:
