docker-menulis untuk nginx dan nodejs server

indonesia
#1

Saya memiliki yang berikut docker-compose.yml berkas:

version: '3'services:    server:        build:            context: ../../            dockerfile: ./packages/website/Dockerfile        command: node /cutting/index.js        environment:            PORT: 8000            NODE_ENV: production        restart: always    nginx:        build:            context: ./            dockerfile: ./nginx/Dockerfile        command: tail -f /dev/null        depends_on:            - server        ports:            - "8000:8000"        restart: always

Dan berikut ini nginx.conf:

worker_processes 1;user nobody nogroup;pid /tmp/nginx.pid;error_log /tmp/logs/nginx.error.log;events {    worker_connections 1024;    accept_mutex off;}http {    include mime.types;    default_type application/octet-stream;    access_log /tmp/logs/nginx.access.log combined;    sendfile on;    server {        proxy_http_version 1.1; # this is essential for chunked responses to work        listen   80; ## listen for ipv4; this line is default and implied        listen   [::]:80 default ipv6only=on; ## listen for ipv6        client_max_body_size 4G;        server_name frontend;        gzip on;        gzip_disable "msie6";        gzip_vary on;        gzip_proxied any;        gzip_comp_level 6;        gzip_buffers 16 8k;        gzip_http_version 1.1;        gzip_types application/javascript text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;        keepalive_timeout 5;        location /static/  {            alias /static/;        }        location  / {            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;            proxy_set_header Host $http_host;            # UNCOMMENT LINE BELOW IF THIS IS BEHIND A SSL PROXY            #proxy_set_header X-Forwarded-Proto https;            proxy_redirect off;            proxy_pass   http://localhost:8000;        }    }}

Jika ini membuat 2 wadah, Bagaimana Saya bisa membuat nginx melihat localhost: 8000 di wadah lain?

#2

Anda menggunakan wadah name seperti yang Anda definisikan di docker-compose.yml. Docker menyediakan alamat IP untuk kontainer bernama melalui DNS dalam setiap kontainer, dan memperbaruinya jika kontainer diperbarui.

Dalam hal ini, Anda menyebutnya server, jadi itulah yang akan Anda gunakan.

    proxy_pass http://server:8000;

Dokumentasi: Jaringan di Compose

#3

Dalam hal ini, Anda perlu menggunakan upstream seperti:

upstream backend {    server express-server:81; #you container/service name}

dan kemudian gunakan:

proxy_pass http://backend
