Introduces an Ansible-based automation for deploying Apache Cloudberry on bare-metal or virtual machines, covering the full deployment workflow from OS configuration to cluster initialization. Key features: - Automates all pre-deployment OS tuning: SELinux, firewall, sysctl, PAM limits, THP, IPC, SSH thresholds, and chronyd - Dynamically calculates memory-dependent sysctl parameters per host: kernel.shmall/shmmax (via PAGE_SIZE and _PHYS_PAGES), vm.overcommit_ratio (via gp_vmem formula), vm.dirty_* (bytes mode for >64GB, ratio mode for <=64GB), and vm.min_free_kbytes (3% of MemTotal) - Installs RPM/DEB packages and configures N-N passwordless SSH via gpssh-exkeys - Initializes the cluster with gpinitsystem including standby coordinator (gpinitstandby with sync verification) - Supports variable cluster sizes via inventory/hosts Files added: - ansible/site.yml main playbook - ansible/group_vars/all.yml deployment variables with inline documentation - ansible/inventory/hosts sample inventory for a 5-node cluster - ansible/ansible.cfg disables host key checking for first-run - ansible/README.md usage guide and prerequisites Assisted-by: Claude Code
