python-shka-gadgets-openstackclient

This is a plugin of OpenStackClient (a.k.a. OSC) to make a single and simple virtual machine handy. In a typical use-case, the virtual machine (names “vanilla” here) given a floating IP address is created and used interactively. Sometimes the vanilla would be shelved; the floating IP address and the security rules are taken away when it is shelved, and these are given again when it is unshelved. After the interactive tasks, the given resources and the images would be cleaned out. The “vanilla” plugin simplifies such resource management in the project work.

Getting Started

This plugin can be installed from PyPI using pip. It will install also a minimal OSC (=python-openstackclient) for the “vanilla” server management.

Example

python3 -m venv venv3
. ./venv3/bin/activate
pip3 install python-shka-gadgets-openstackclient
. ./openrc.sh

The openrc.sh here is a script for OSC environment, which you can download from the OpenStack dashboard of your project. The script will ask a password of the project.

openstack vanilla create --flavor standard.tiny --key-name mykey --image Ubuntu-18.04 test

It creates a vanilla server named test on standard.tiny flavor from the Ubuntu 18.04 image. The specified key pair must be registered already. It gives a floating IP address to the vanilla and prepares a security group to login via ssh.

openstack server ssh --login ubuntu test

You can login to test as avobe if the login name is ubuntu.

mkdir -p ~/mnt/ubuntu
sshfs ubuntu@`openstack vanilla show ip test`: ~/mnt/ubuntu
ls -l ~/mnt/ubuntu
umount ~/mnt/ubuntu

You can mount ubuntu’s home directory of test by sshfs, if you prefer.

openstack vanilla shelve test

It shelves test - It’s good when you will leave the project temporarily. The floating IP address and the security group is taken away. The old image used for the previous unshelve is removed.

openstack vanilla unshelve test

You can unshelve test when you restart the project. The floating IP address and the security group are configured again.

openstack vanilla resize --flavor standard.xxlarge test

You can resize test when you need more power, if the project supports it.

openstack vanilla delete test

After the project you can remove test completely.
