Dockerize Nova client
With OVH Public Cloud, it is possible for you to control your OpenStack instances directly from the Nova client.
It is rather practical to go through the command line rather than having to access the manager which is often, let us say it, slow.
But to avoid having to prepare each time a working environment compatible with Nova, I find more interesting to directly create a Docker image for this purpose. In this way, no more need to install anything except the Docker daemon on its workstation.
The DockerFile looks like :
FROM debian:latest RUN apt-get update && \ apt-get install -y \ python-glanceclient \ python-novaclient env OS_AUTH_URL="" env OS_TENANT_ID="" env OS_TENANT_NAME="" env OS_USERNAME="" env OS_PASSWORD="" env OS_REGION_NAME=""
Note that I use the basic debian image because I already have it locally, but you can replace the bone with the one you want and adapt the content of RUN.
You also need to fill the environment variables with information about your OpenStack env.
Let’s go with :
sudo docker build -t clientNova .
Then run your container as follow :
sudo docker run --rm -it novaClient bash
You can add alias to your
alias nova="sudo docker run --rm -it novaClient bash"
