dockerコンテナのnginxでConnection refused
dockerコンテナでnginxを動作させてみる。
nginxを起動してcurlでアクセスしてみたものの、Connextion refusedと出力されてしまう。
$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 50802d9a477a yukofeb/nginx "/usr/sbin/nginx -g '" 17 minutes ago Up 8 minutes 0.0.0.0:80->80/tcp nginx1 $ curl localhost:80 curl: (7) Failed to connect to localhost port 80: Connection refused
ドキュメントによるとDOCKER_HOST
が0.0.0.0
に設定されていないことが原因らしい。
Installation on Mac OS X
DOCKER_HOSTのIPを確認する方法は以下。
$ docker-machine ip default 192.168.99.100
これでOK!
$ curl 192.168.99.100:80 <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { width: 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working.
