[英]How to use nginx on Docker for Windows as reverse proxy for localhost?
I am using Docker for Windows and want to set up nginx as reverse proxy.我在 Windows 上使用 Docker,并希望将 nginx 设置为反向代理。 All is working fine but if I want to define a proxy to my localhost I always get a 502 or 504 error.
一切正常,但如果我想为本地主机定义代理,我总是会收到 502 或 504 错误。 I thought setting an
extra_host
would solve my problem but didn't.我认为设置一个
extra_host
会解决我的问题,但没有。 Is there any other IP that I can try to set as host or is something else wrong?我可以尝试将任何其他 IP 设置为主机还是其他错误?
docker-compose.yml: docker-compose.yml:
version: '3'
volumes:
etc:
driver: local
services:
nginx:
container_name: nginx
image: nginx:latest
volumes:
- ./etc:/etc/nginx
ports:
- 8088:80
extra_hosts:
- localhost:127.0.0.1
nginx.conf: nginx.conf:
user nginx;
worker_processes 1;
events {
}
http {
server {
listen 80;
server_name localhost;
location /auth {
proxy_pass http://localhost:8082/auth;
}
location /graphql {
proxy_pass http://localhost:8080/graphql;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_http_version 1.1;
}
location ^~ / {
proxy_pass http://localhost:8082/auth;
}
location /sso/login {
proxy_pass http://localhost:8082/auth;
}
}
}
PS: all referred paths are docker-containers eg /auth
is a keycloak authentification server PS:所有引用的路径都是 docker-containers,例如
/auth
是一个 keycloak 身份验证服务器
I solved this problem myself.我自己解决了这个问题。 If you open the docker settings (right-click on docker icon) then you have the following network settings.
如果您打开 docker 设置(右键单击 docker 图标),那么您将获得以下网络设置。
Per default the DNS server is set to automatic -> change this to fixed 8.8.8.8 Then you can access your containers with 10.0.75.2 instead localhost.
默认情况下,DNS 服务器设置为自动 -> 将其更改为固定 8.8.8.8然后您可以使用10.0.75.2而不是 localhost 访问您的容器。 Last but not least add this address as
extra_host
to your docker-compose file and fire it up.最后但并非最不重要的是,将此地址作为
extra_host
添加到您的extra_host
-compose 文件中并启动它。
version: '3'
volumes:
etc:
driver: local
services:
nginx:
container_name: nginx
image: nginx:latest
volumes:
- ./etc:/etc/nginx
ports:
- 8088:80
extra_hosts:
- localhost:10.0.75.2
Looking at the documentation, with docker for mac we can use host.docker.internal
to resolve the internal IP used by the host查看文档,使用
host.docker.internal
for mac我们可以使用host.docker.internal
来解析主机使用的内部IP
location /api {
proxy_pass http://host.docker.internal:8080;
}
