Portainer 无法进入容器控制台 [已解决]

Portainer 无法进入容器控制台，一直显示这样：

[TMtina]

Portainer 的 Nginx 配置文件中缺少 WebSocket 连接所需的标头，导致 Portainer 终端连接失败，您可以部署下面这个容器，它会自动检查并修补 Nginx 配置，然后就可以连接终端了。

代码： 全选

version: '3'

services:
  nginx-fixer:
    image: alpine:latest
    container_name: nginx-websocket-fix
    restart: always
    pid: host
    volumes:
      - /etc/nginx/conf.d:/host_conf_d
    entrypoint:
      - /bin/sh
      - -c
      - |
        echo "Checking Portainer Nginx config..."
        CONF="/host_conf_d/portainer.conf"

        # 1. Check if file exists and needs patching
        if [ -f "$$CONF" ] && ! grep -q "proxy_set_header Upgrade" "$$CONF"; then
          echo "Fix missing. Applying patch..."
          
          # Insert the websocket headers before the proxy_pass line
          # Note: We use $$ to escape variables in docker-compose
          sed -i '/proxy_pass/i \    proxy_http_version 1.1;\n    proxy_set_header Upgrade $$http_upgrade;\n    proxy_set_header Connection "Upgrade";' "$$CONF"
          
          echo "Patch applied. Reloading Host Nginx..."
          # Send HUP signal to host nginx processes to reload config
          kill -HUP $$(pidof nginx)
        else
          echo "Config is already patched or missing."
        fi

        # 2. Sleep forever to keep container "Running" so it starts on next boot
        echo "Job done. Sleeping to maintain 'Running' status for next reboot..."
        sleep infinity
