Portainer Docker容器反向代理配置后登录异常问题（已解决）

我在FreeNAS中运行了一台CentOS虚拟机，虚拟机上安装Docker并部署了多个容器。我用Nginx容器接收本地（80和443端口）及外部（443端口）流量，尝试为Portainer配置虚拟主机，但只取得了部分成功。

我的配置文件 #

nginx.conf #

user www-data; worker_processes 1; error_log /var/log/nginx/error.log warn; #error_log /var/log/nginx/debug.log debug; pid /var/run/nginx.pid; events {worker_connections 1024;} http { upstream backend {server app-server:9000;} upstream onlyoffice {server onlyoffice-document-server:443;} ## allow cloudflare only ips include /etc/nginx/myconfig/cloudflare.conf; include /etc/nginx/mime.types; default_type application/octet-stream; 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 /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; ## proxy mappings include /etc/nginx/myconfig/proxy.conf; ## # HTTP host for internal services only ## server { listen 0.0.0.0:80; server_name localhost; server_tokens off; ## Redirects all traffic to the HTTPS host root /nowhere; ## root doesn't have to be a valid path since we are redirecting rewrite ^ https://$host$request_uri? permanent; } ## ## HTTPS host ## server { listen 443 ssl; listen [::]:443 ssl; server_name cloud.mydomain.com www.mydomain.com; server_tokens off; root /var/www/html; ## block non-cloudflare ips if ($cloudflare_ip != 1) {return 444;} ## SSL settings include /etc/nginx/myconfig/ssl.conf; client_max_body_size 1G; # 0=unlimited - set max upload size fastcgi_buffers 64 4K; # Enable gzip but do not remove ETag headers include /etc/nginx/myconfig/gzip.conf; index index.php; error_page 403 /core/templates/403.php; error_page 404 /core/templates/404.php; rewrite ^/.well-known/carddav /remote.php/dav/ permanent; rewrite ^/.well-known/caldav /remote.php/dav/ permanent; ## Locations ### # For Letsencrypt certificate verification location ~ /.well-known/acme-challenge { root /var/www/html/; allow all; } # Locations (nextcloud, calibre, onlyoffice, portainer, etc) on www. and cloud. include /etc/nginx/myconfig/locations/*.conf; location = /robots.txt { allow all; log_not_found off; access_log off; } } # virtual hosts include /etc/nginx/myconfig/vhosts/*.conf; }

portainer.conf #

server { listen 80; server_name portainer.mydomain.com; location / { return 301 https://$server_name$request_uri; } } server { listen 443 ssl; server_name portainer.mydomain.com; resolver 127.0.0.11 valid=30s ipv6=off; set $upstream http://portainer:9000; ssl_certificate /keys/server.crt; ssl_certificate_key /keys/server.key; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffers 32 4k; location / { proxy_http_version 1.1; proxy_set_header Connection ""; proxy_pass $upstream; #tried this with and without trailing slash } location /api/websocket/ { proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_http_version 1.1; proxy_pass $upstream/api/websocket; #tried this with and without trailing slash } }

问题现象 #

当访问portainer.mydomain.com时，主认证页面可以打开，但右上角出现如下错误提示：

Failure [$resource:badcfg] Error in resource configuration for action `query`. Expected response to contain an array but got an object (Request: GET api/endpoints) http://errors.angularjs.org/1.5.11/$resource/badcfg?p0=query&p1=array&p2=object&p3=GET&p4=api%2Fendpoints

输入用户名和密码后点击登录无任何反应。另外，通过Docker主机暴露的9000端口直接连接Portainer一切正常。

问题解决 #

2018年5月12日更新：问题已解决！原因是我在测试不同配置时，Firefox缓存了旧的内容，清除浏览器缓存后，所有功能都正常工作了。
