docker elasticsearch容器未转发端口（macOs）

Question

我设置了一个容器来运行elasticsearch。服务启动，但是我无法通过curl或浏览器连接到该服务。

 RUN \
 cd /tmp && \
 wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-  1.3.2.tar.gz && \
 tar xvzf elasticsearch-1.3.2.tar.gz && \
 rm -f elasticsearch-1.3.2.tar.gz && \
 mv /tmp/elasticsearch-1.3.2 /elasticsearch

 # Define mountable directories.
 VOLUME ["/data"]

 # Define default command.
  CMD ["/elasticsearch/bin/elasticsearch"]

 EXPOSE 9200
 EXPOSE 9300

连接到http://localhost:9200没有任何效果。docker ps显示端口；

 0.0.0.0:49179->9200/tcp, 0.0.0.0:49180->9300/tcp
 ...
 net::ERR_ADDRESS_UNREACHABLE

我是否缺少一些配置值？谢谢！

[更新]我也在运行命令中尝试了-p

 docker run -i -p 9200:9200 -p 9300:9300 -t --rm -P team1/image1

我测试了您的Dockerfile，但是它可以正常工作。

FROM dockerfile/java
RUN \
  cd /tmp && \
  wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.3.2.tar.gz && \
  tar xvzf elasticsearch-1.3.2.tar.gz && \
  rm -f elasticsearch-1.3.2.tar.gz && \
  mv /tmp/elasticsearch-1.3.2 /elasticsearch
# Define mountable directories.                                                                                    
VOLUME ["/data"]
# Define default command.                                                                                          
CMD ["/elasticsearch/bin/elasticsearch"]
EXPOSE 9200
EXPOSE 9300

我尝试构建此Dockerfile并运行它。

$ docker build -t 25312935 .
$ docker run -t -p 9200:9200 -p 9300:9300 --rm 25312935

如下所示，请求127.0.0.1:9200返回json响应。

$ curl 127.0.0.1:9200
{
  "status" : 200,
  "name" : "Black Crow",
  "version" : {
"number" : "1.3.2",
  },
  "tagline" : "You Know, for Search"
}

检查您的-p选项。这意味着发布容器的主机端口。如果您未明确编写主机的端口，则docker如下分配随机端口。

$ docker run -t -p 9200 -p 9300 --rm 25312935
$ docker ps -l
CONTAINER ID        IMAGE                COMMAND                CREATED             STATUS              PORTS                                              NAMES
1aa4c2c84d04        25312935:latest      /elasticsearch/bin/e   15 seconds ago      Up 15 seconds       0.0.0.0:49153->9200/tcp, 0.0.0.0:49154->9300/tcp   sad_shockley

0.0.0.0:49153->9200/tcp 表示您可以通过主机的49153端口访问容器的9200端口。

$ curl 127.0.0.1:49153
{
  "status" : 200,
  "name" : "Golem",
  "version" : {
"number" : "1.3.2",
  },
  "tagline" : "You Know, for Search"
}

因此，如果您要使用主机s 9200 port, explicitly write the host port like-p 9200：9200
or-p 0.0.0.0：9200：9200`

$ docker ps -l
CONTAINER ID        IMAGE                COMMAND                CREATED             STATUS              PORTS                                            NAMES
eeb3396b1ecc        25312935:latest      /elasticsearch/bin/e   59 seconds ago      Up 58 seconds       0.0.0.0:9200->9200/tcp, 0.0.0.0:9300->9300/tcp   high_elion

如果仍然无法解决问题，请尝试--net=host选择。您可以使用此选项在容器内使用主机网络堆栈。

$ docker run -t --net=host --rm 25312935
$ curl 127.0.0.1:9200
{
  "status" : 200,
  "name" : "Black Crow",
  "version" : {
"number" : "1.3.2",
  },
  "tagline" : "You Know, for Search"
}

如果两者都不起作用，我认为您需要检查其他网络配置。
