Chunk 6.0
In this chunk, we committed the Ansible deployment scripts for FGW clusters (7 roles, 5 playbooks, inventory structure) and created a comprehensive Docker-based test harness to validate them. The test environment includes a YugabyteDB container, three target hosts (two Kuri nodes, one S3 frontend) running Ubuntu 24.04 with systemd and SSH, and an Ansible controller container. We then ran the test suite and iteratively fixed several issues: the YB health check needed the correct hostname; the controller needed `psql`, `cqlsh`, and `sshpass` installed; the test inventory was missing `group_vars` for kuri and s3_frontend; target volumes had read‑only mount issues; and `pam_nologin` blocked SSH logins after container startup. The tests progressed through connectivity checks and YugabyteDB initialization, but the Kuri deployment failed because `kuri init` was run before the `settings.env` file was generated, causing a database connection error. The session ends with us editing the Kuri role to reorder tasks so that `settings.env` is placed before the `kuri init` step, ensuring the database connection parameters are present during initialization.
