# Kolla-Ansible Day-2 Operations -- Infrastructure Lifecycle Management Kolla-Ansible is not just a deployment tool -- it is the infrastructure lifecycle manager. The initial `kolla-ansible deploy` is a one-time event. Everything after that -- reconfiguration, upgrades, container management, maintenance -- is what this skill covers. Operators will use these procedures repeatedly throughout the cloud's operational life. **The operational command set:** | Command | Purpose | When to Use | |---------|---------|-------------| | `kolla-ansible reconfigure` | Regenerate configs and restart affected services | After globals.yml or config override changes | | `kolla-ansible upgrade` | Pull new images and upgrade services | Minor or major OpenStack release upgrades | | `kolla-ansible prechecks` | Validate configuration before applying | Always run before reconfigure or upgrade | | `kolla-ansible stop` | Stop all or specific service containers | Maintenance, troubleshooting | | `kolla-ansible deploy` | Deploy services (also used for redeployment) | After stop, or for new services | | `kolla-ansible pull` | Pull container images without deploying | Pre-stage images before upgrade window | **Relationship to the kolla-ansible deployment skill:** The deployment skill (Phase 313) covers the initial bootstrap, deploy, and post-deploy verification that brings the cloud online for the first time. This skill picks up where deployment left off. They share the same inventory and globals.yml,
