This is a collection of workshops to learn how to use OpenStack on OVH Public Cloud (although it can be adapted easily to different cloud provider using OpenStack).
The workshops are organized as follows:
-
Basic resource management: simple manipulation of resources
-
Advanced resource management: more complex manipulation of resources
-
Orchestration with Heat: manage infrastructure the DevOps way
Before beginning the workshops, the following elements should have been communicated to you:
- the IP address of the bounce server
- the password of the bounce user
- the ID of the container to use
With this information you can connect to the bounce server:
ssh bounce@XXX.XXX.XXX.XXXThe banner will ask to enter an ID:
bounce@XXX.XXX.XXX.XXX's password:
[...]
What is your ID? (desktop id or firstname.name)
<enter ID>
Connecting to ID's environement
root@XXXXXX:~#You are now logged in.
Once logged in you need to install the openstack command-line interface:
apt-get install python-openstackclientNow let's add the completion for bash:
openstack complete > /etc/bash_completion.d/osc.bash_completion
source /etc/bash.bashrcFinally, check and load the credentials of the OpenStack project that was prepared for you:
cat credentials
source credentialsCheck that you have sufficient quotas to complete the workshops:

The minimum quotas that you will need for the workshops are:
- cores >= 6
- gigabytes >= 100
- instances >= 6
- key-pairs >= 1
- networks >= 2
- per-volume-gigabytes >= 10
- ram >= 25000
- snapshots >= 6
- subnets >= 4
- volumes >= 10
🎆 Congratulations you are now ready to use OpenStack and complete the workshops.
For anyone else wanting to try this, you need:
- a valid OVH Public Cloud project
- a user on this project
- an openrc file for this user
- a terminal with the
openstackCLI installed or use the terminal app integrated in the OVH manager.
