docker - Docker流利|无法将请求从主机转发到Docker守护程序

Question

我正在尝试在https://docs.fluentd.org/v0.12/articles/install-by-docker之后运行fluentd docker示例

无法向容器发出请求。出现以下错误。

$curl -X POST -d 'json={"json":"message"}' http://localhost:9880/sample.test
curl: (56) Recv failure: Connection reset by peer

我尝试远程登录:

$ telnet localhost 9880
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

看起来Docker容器正在成功运行:

$ docker run -p 9880:9880 -it --rm --privileged=true -v /tmp/fluentd:/fluentd/etc -e FLUENTD_CONF=fluentd.conf fluent/fluentd

Answer 1

我只是在示例中完成了所有步骤。没有错误，一切正常。
检查9880端口是否已打开(netstat -neta |grep 9880)。
也许您有防火墙(Windows)或某些iptables规则。
看来是防火墙问题。请检查一下。
