A Git repository is required to store the configuration for your specific infrastructure. The manager node needs to have access to this repository. An SSH deploy/access key for read-only access is sufficient.

Before creating the configuration repository, infrastructure specific information needs to be provided:

  • NTP servers

  • DNS servers

  • FQDNs and IP addresses for the API endpoints

  • desired versions of OSISM, OpenStack, Ceph and Docker

  • CIDRs of networks for Ceph

  • SSL certificate, if one is used


After the deployment of the manager node, it is possible to generate a self-signed SSL certificate using an included Ansible playbook. See Generate self-signed certificates (<= Train) for more information.

Usually the configuration repository is prepared on your workstation. After the repository creation, it needs to be pushed to a central Git server, to make it available to the manager node.


Installation of gcc, python-development and git packages is a prerequisite to install required Python packages.

apt-get install git build-essential python3-dev

It is recommended to use a virtual environment when installing packages from PyPI.

virtualenv -p python3 .venv
source .venv/bin/activate

Install the requirements for cookiecutter.

pip3 install -r


When running cookiecutter, infrastructure specific information needs to be provided.

A list with all parameters can be found in the cookiecutter.json configuration file inside the configuration repository. A description of the individual parameters can be found in the README file of the repository.

Create a Git repository inside the newly created cfg-osism directory. Be careful not to forget dotfiles like .gitignore.

cd cfg-osism
git init
git add .
git commit -m "Initial commit"

Push the repository to a Git server, so it will be available to the manager node.

git remote add origin <your-git-server>/cfg-osism
git push --set-upstream origin master

Directory structure after the initial commit in the Git repository. The secrets directory is only stored in the repository for test environments.
