问题描述
我设置了一个容器来运行elasticsearch。服务启动，但是我无法通过curl或浏览器连接到它。
I have a container set up to run elasticsearch. The service starts but I can't connect to it via curl or the browser.
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 不会产生任何结果。 docker ps显示端口;
Connecting to http://localhost:9200 yields nothing. The docker ps shows ports;
0.0.0.0:49179->9200/tcp, 0.0.0.0:49180->9300/tcp
...
net::ERR_ADDRESS_UNREACHABLE
我失踪了吗一些配置值？谢谢！
Am I missing some config value? THANKS!
[更新]我也在运行命令中尝试过-p
[Update] I also tried the -p in the run command
docker run -i -p 9200:9200 -p 9300:9300 -t --rm -P team1/image1
推荐答案
我测试了您的Dockerfile，但它确实有效。
I tested your Dockerfile, but it just works.
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。
I try to build this Dockerfile and run it.
$ 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。 / p>
As you can see below, request 127.0.0.1:9200 returns json response.
$ 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。如果您未明确写入主机端口，则docker会如下分配随机端口。
Check your -p option. It means publising container's port to host. If you doesn't write explicitly host's port, docker assign random port like below.
$ 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。
0.0.0.0:49153->9200/tcp means that you can access container's 9200 port through host's 49153 port.
$ curl 127.0.0.1:49153
{
"status" : 200,
"name" : "Golem",
"version" : {
"number" : "1.3.2",
},
"tagline" : "You Know, for Search"
}
因此，如果要使用host s 9200端口，显式编写主机端口，例如 -p 9200：9200 或 -p 0.0.0.0：9200：9200`
So if you want to use hosts 9200 port, explicitly write the host port like-p 9200:9200or-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
如果仍然无法执行，请尝试使用-net = host 选项。您可以使用此选项在容器内使用主机网络堆栈。
If this still doesn't work, try to --net=host option. You can use the host network stack inside the container by using this option.
$ 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。
If both don't work, I think that you need to check your other network configuration.
