This project easily deploys OpenStack in docker & docker-compose. This is mainly for development purpose.
NOTE: This is only tested on x64 Ubuntu 22.04 machine. It may work on other Linux Distributions. Other CPU architectures and operating systems cannot be supported.
The docker-compose command launches an OpenStack environment based on preconfigured container images. The images are huge and will take some time to download, but once complete, you should be up and running in less than a minute thereafter.
An example is shown below:
curl -sLO https://raw.githubusercontent.com/bobuhiro11/containerized-devstack/main/docker-compose.yaml
sudo docker-compose upYou can use the OpenStack CLI in the container.
sudo docker-compose exec controller openstack compute service list
