Installs glusterfs and heketi into kubernetes for dynamic persistent volume handling.
Ready to use.
Installation can be done using ansible-galaxy collection install.
In your hosts file define control and compute node groups. To use the roles, just include them into your playbook.
- hosts: control compute
user: root
roles:
- telekom.k8s_gluster_heketi_ansible.preparation
- telekom.k8s_gluster_heketi_ansible.gluster_host
- telekom.k8s_gluster_heketi_ansible.heketi
vars:
- gluster_host_ssh_priv_key: "path/to/keys/file"Note: there is also a telekom.k8s_gluster_heketi_ansible.gluster_container role. This is seen as a replacement drop in for the gluster_host. Instead of using glusterd on the host, the official gluster container are used. The problem is, that this has some darwbacks as it uses lvm in an udev free space.

Some ideas and even source code it used from the following projects. All the projects are also licensed under Apache 2.0 license. When source code is used it is marked as such.
- ansible-role-k8s-heketi-gluster https://github.com/manics/ansible-role-k8s-heketi-gluster This project followed a very similar approach as k8s-gluster-heketi-ansible. The problem is, that this is not longer maintained and does not support up to date heketi versions and uses commands / shell for kubernetes instead of the Ansible 'k8s' module which makes things much easier to handle.
- gluster-kubernetes https://github.com/gluster/gluster-kubernetes This project provides (mostly) a shell script to install and configure heketi. The project is archived (read-only) and there is no active developemnt done. The result is, that it does not work with current kubernetes versions.
