Saya mencoba membuat pengaturan multi-kontainer berbasis docker dengan proxy terbalik untuk melayani beberapa domain, di mana situs web, database, dan proxy terbalik berbasis nginx berjalan dalam wadah, tetapi saya tidak tahu apa yang saya lewatkan (saya baru mengenal nginx).
Rincian:
- Wadah docker berbasis NginX untuk proxy terbalik
- Ada 2 domain yang saya miliki
- misalnya.:
my_example_domain_1.com,my_example_domain_2.net
- misalnya.:
- Saya ingin meletakkan wadah di belakang setiap nama domain untuk melayani dua domain
- Saya ingin menjalankan dua situs web terpisah: misalnya: dua situs web WordPress
- Saya memerlukan rute NginX antara dua domain dan wadah yang sesuai
Contoh saya: (basedir: multi-container)

- Tes: jika saya mengambil
revproxydaridocker-compose.ymlfile dan eksekusidocker-compose up -ddi mesin desktop saya, saya dapat mengakses kedua situs web (tanpa revproxy) di port kontainer:localhost:8081,localhost:8082 - PROD: ketika saya mengeksekusi
docker-compose up -ddi server Saya, situs web tidak dapat dijangkau - PROD: semua kontainer tampaknya berjalan tanpa kesalahan
