【问题描述】:
我真的很难过,我可以帮助找出为什么我的环境变量没有从 Docker 传输到 nginx 配置文件。
我有一个docker-compose.yml
nginx:
image: nginx
container_name: proxier
volumes:
- ./conf/nginx.conf:/etc/nginx/nginx.conf
- ./conf/server.nginx.conf.tpl:/etc/nginx/server.nginx.conf.tpl
- ./build/web:/srv/static:ro
- ./docker/proxier:/tmp/docker
ports:
- "80:80"
- "443:443"
environment:
- HOST_EXTERNAL_IP=localhost
- DEVSERVER_PORT=8000
- DEVSERVICE_PORT=5000
command: /bin/bash -c "env && envsubst '$$HOST_EXTERNAL_IP $$DEVSERVER_PORT $$DEVSERVICE_PORT' < /etc/nginx/server.nginx.conf.tpl > /etc/nginx/conf.d/default.conf && nginx -g 'daemon off;'"
我有一个nginx.conf 文件
user nginx;
worker_processes 1;
error_log /dev/stdout warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
client_max_body_size 100g;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /dev/stdout main;
sendfile off;
tcp_nopush on;
keepalive_timeout 65;
gzip on;
server_tokens off;
upstream app {
server myapp:8000 fail_timeout=0;
}
include /etc/nginx/server.nginx.conf.tpl;
}
我有一个server.nginx.conf.tpl 文件
server {
listen 80;
listen 443 ssl http2 default_server;
server_name localhost;
index index.html;
location ^~ /services/ {
proxy_pass https://myurl.com;
proxy_set_header USER_DN $ssl_client_s_dn;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
location / {
proxy_http_version 1.1;
proxy_set_header Connection "keep-alive";
proxy_pass http://${HOST_EXTERNAL_IP}:${DEVSERVER_PORT}; # Won't read environment variables here
}
}
但是当我运行它时,我得到了错误
nginx: [emerg] unknown "host_external_ip" variable 我正在使用envsubst 正确地根据docs 从 docker 传递环境变量
【问题讨论】:
-
您在主
nginx.conf末尾的include指令包括未渲染的...tpl文件;它应该包含呈现的default.conf。
