This Skill prevents slow, flaky, or wasteful Docker and Compose setups for PHP+Swoole services by standardizing the non-obvious house rules and container-runtime behaviors that matter in production.
Ask an AI to review your Dockerfile and docker-compose.yml for a PHP 8.3 + Swoole 6 service and enforce the docker-expert house rules for multi-stage builds, healthchecks, opcache/ini tuning, graceful shutdown, and Compose depends_on health gating.
High-intent search queries and answers about installing and using this skill.
Docker healthchecks prevent startup race conditions by gating Compose depends_on dependencies, ensuring PHP Swoole containers wait for required services to be fully ready. This avoids hidden deadlocks and startup flakiness.
Long-running PHP Swoole workloads require tuned opcache settings including preload, JIT configuration, and timestamp validation strategy to match Swoole worker lifecycles and prevent memory exhaustion. These settings ensure stable persistent process performance.
PHP Swoole containers fail to shut down gracefully when lacking correct PID 1 signal handling. Using tini for PID 1 management and configuring graceful shutdown timing ensures Swoole workers terminate cleanly without truncating active requests.
Multi-stage Docker builds copy compiled PHP extensions and required shared libraries reliably from builder stages, avoiding brittle single-file approaches. Using BuildKit ensures proper artifact copying for Swoole-ready images without missing runtime dependencies.
Common Docker Compose anti-patterns causing Swoole OOM or fd starvation include missing resource budgeting and incorrect dependency gating. Setting Swoole-relevant memory and file descriptor limits explicitly prevents these runtime crashes.
