PHP: Guzzle 6 - cURL error 7 Connection Refused
This turned out to be a relatively simple fix. The problem was the two fpm containers weren't aware of each other, and by referring to app-one.local in app-two's request, app-two was basically sending the request into the void. The fix for this was as follows:
version: '3.3'services: nginx: image: evild/alpine-nginx:1.9.15-openssl container_name: nginx volumes: - ./app-one:/var/www/app-one/:ro - ./app-two:/var/www/app-two/:ro - ./nginx/conf/nginx.conf:/etc/nginx/conf/default.conf:ro - ./nginx/conf.d:/etc/nginx/conf.d:ro - ./certs:/etc/nginx/certs ports: - 80:80 - 443:443 expose: - "80" - "443" depends_on: - app-one - app-two environment: TZ: "America/Los_Angeles" # This is the fix networks: default: aliases: - app-one.local - app-two.local app-one: environment: TZ: "America/Los_Angeles" image: joebubna/php container_name: app-one restart: always volumes: - ./app-one:/var/www/app-one ports: - 9000:9000 # This is the fix networks: - default app-two: environment: TZ: "America/Los_Angeles" image: joebubna/php container_name: app-two restart: always volumes: - ./app-two:/var/www/app-two ports: - 9001:9000 # This is the fix networks: - default db: image: mysql:5.6 container_name: mysql volumes: - db-data:/var/lib/mysql - ./mysql/my.cnf:/etc/mysql/conf.d/ZZ-mysql.cnf:ro environment: MYSQL_ROOT_PASSWORD: root MYSQL_USER: user MYSQL_PASSWORD: password MYSQL_DATABASE: cora TZ: "America/Los_Angeles" ports: - 3306:3306 expose: - "3306" # This is the fix networks: - defaultvolumes: db-data:# This is the fixnetworks: default: driver: bridge
What I ended up doing is creating an overlay network, and making the nginx container aware of each of the fpm's domain name. This allows the two containers to now send requests back and forth between each other via FQDN as opposed to IP or container ID/name. A simple thing to overlook in hindsight.
