Symptom & Impact

Bastille deployment pipeline stops when template apply stage fails.

Environment & Reproduction

Appears when template dependencies or bridge networking assumptions changed.

bastille list
bastille bootstrap 14.0-RELEASE

Root Cause Analysis

Template scripts reference missing datasets, packages, or invalid interface settings.

Quick Triage

Run bastille in verbose mode and isolate first failing action.

Step-by-Step Diagnosis

Validate bastille.conf, ZFS layout, and host bridge network state.

grep -n 'bastille_' /usr/local/etc/bastille/bastille.conf
ifconfig bridge0

Solution – Primary Fix

Correct dataset/network prerequisites and reapply the template idempotently.

zfs create -p zroot/bastille/jails 2>/dev/null || true
bastille template  

Solution – Alternative Approaches

Convert fragile template steps into tested Ansible roles for reproducibility.

Verification & Acceptance Criteria

Template completes and jail service endpoints respond as expected.

bastille list
bastille cmd  service -e

Rollback Plan

Destroy failed jail instance and recreate from previous known-good snapshot.

Prevention & Hardening

Version templates and run automated lint/tests before production apply.

Related Errors & Cross-Refs

template apply failed, bridge interface not found, package fetch error in jail.
