A set of installation and setup scripts for creating a cluster of CentOS servers that boot from the ZFS filesystem.
Install CentOS with a ZFS filesystem. Should be run from a CentOS installation, not a live USB. See the beginning of the script for instructions.
Install Ubuntu with a ZFS filesystem. Should be run from a live USB (unlike the CentOS script) of the desktop version of Ubuntu.
Install XRDP remote desktop, ssh access, firewall, utility packages, and xfce desktop settings.
Common functions for all the scripts, such as output text coloring, error messages, and disk utilities
- backup-script-setup.sh -- Install a cron job that backs up the ZFS pool with syncoid to another location specified by the user.
- admin-tools-setup.sh -- enable remote ssh login, install xrdp, tmux, and a way to remotely access the system with ssh tunneling if the machine becomes not externally accessible.
- k8s-install.sh -- install kubectl, kubeadm, and kubefed packages from kubernetes.
- master-node-setup.sh -- set up a machine as a master node of a cluster and join a federated group of clusters in different locations using kubefed.
- worker-node-setup.sh -- set up a machine as a worker node and join the local cluster with kubeadm as specified by the master node.
- node-setup-common.sh -- a script that holds all the common elements between the worker and master nodes. This should not be called directly, the other scripts will call it as needed.
- Config files to further automate the setup and to provide the same options to multiple scripts
- Scripts to install monitoring tools that will email the user when ZFS has a fault or when a kubernetes node fails.
