我们有一组 dockerized 微服务，它们已经在具有私有内部 IP 的 VM 上运行。我配置了一个 dockerized nginx 以在这些微服务前面设置反向代理，但我得到 nginx：在上游"ms1"错误中找不到 [emerg] 主机。
下面是 nginx.conf 文件
#user nobody;
#Defines which Linux system user will own and run the Nginx server
worker_processes 4;
#Referes to single threaded process. Generally set to be equal to the number of CPUs or cores.
#error_log logs/error.log; #error_log logs/error.log notice;
#Specifies the file where server logs.
#pid logs/nginx.pid;
#nginx will write its master process ID(PID).
events {
worker_connections 1024;
# worker_processes and worker_connections allows you to calculate maxclients value:
# max_clients = worker_processes * worker_connections
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
# If serving locally stored static files, sendfile is essential to speed up the server,
# But if using as reverse proxy one can deactivate it
#tcp_nopush on;
# works opposite to tcp_nodelay. Instead of optimizing delays, it optimizes the amount of data sent at once.
#keepalive_timeout 0;
keepalive_timeout 65;
# timeout during which a keep-alive client connection will stay open.
gzip on;
# tells the server to use on-the-fly gzip compression.
server {
listen 8080;
server_name your-domain.com www.your-domain.com;
#root configuration for static files.
root /usr/share/nginx/html;
index index.html index.htm;
error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
upstream consumer-portal {
server consumer-portal:9006;
}
upstream download-zip-service {
server download-zip-service:9012;
}
server {
listen 8080;
server_name www.example.com;
location /consumer-portal/ {
proxy_pass http://consumer-portal:9006/;
}
location /download-zip-service/ {
proxy_pass http://download-zip-service:9012/;
}
}
}
以下是我的Dockerfile的内容：
FROM nginx
RUN rm /etc/nginx/conf.d/default.conf
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 8080
CMD ["nginx", "-g", "daemon off;"]
以下是docker-compose.yml文件的内容
version: '3'
services:
nginx:
restart: always
build: ./conf/
volumes:
- ./mysite.template:/etc/nginx/conf.d/mysite.template
ports:
- "8080:8080"
networks:
- cloud
networks:
cloud:
driver: bridge
我使用网络的名称作为云，因为容器消费者门户和下载zip服务在云网络上运行。
我在运行命令时出现以下错误：
docker-compose build
docker-compose up
nginx_1 | 2018/07/02 20:48:52 [emerg] 1#1: host not found in upstream "consumer-portal:9006" in /etc/nginx/nginx.conf:50
nginx_1 | nginx: [emerg] host not found in upstream "consumer-portal:9006" in /etc/nginx/nginx.conf:50
任何指导不胜感激！
根据这篇文章的建议，新的 conf 文件：
#user nobody;
#Defines which Linux system user will own and run the Nginx server
worker_processes 4;

#error_log logs/error.log; #error_log logs/error.log notice;
#Specifies the file where server logs.
#pid logs/nginx.pid;
#nginx will write its master process ID(PID).

如果要使用主机名指定上游服务器，则需要指定解析器
