JMeter - docker - java.net.connectexception [英] JMeter - docker - java.net.connectexception

问题描述

我正在尝试使用JMeter在AWS EC2实例中进行分布式负载测试。

我有1个主站和2个从站。都是ubuntu的实例。
他们都安装了java和jmeter。

我能够成功地在奴隶无问题的情况下执行测试。 （当我不使用docker时）（JMeter使用RMI来控制从站）

现在，我正在考虑在奴隶中使用docker，因为我可能添加更多的从站。我不想每次都设置从机。所以Docker似乎是一个不错的选择。

在docker容器中，一切似乎都是正确的，所有必需的端口都是打开的。

问题：

每当我使用docker容器在从站中运行jmeter-server，如果我尝试从主服务器连接到它，它抛出 java.net.connectexception连接拒绝连接< ip address> 错误。

如果我从主人到奴隶，可以成功连接。

我的码头文件：

  FROM ubuntu 
运行apt-get update 
运行apt-get -y安装wget 
运行apt-get -y install default-jre 
 RUN mkdir / jmeter 
 RUN cd / jmeter /; wget http://www.us.apache.org/dist//jmeter/binaries/apache-jmeter-2.13.tgz; tar -xzf apache-jmeter-2.13.tgz; rm apache-jmeter-2.13.tgz 
 ENV JMETER_HOME /jmeter/apache-jmeter-2.13/ 
 ENV PATH $ JMETER_HOME / bin：$ PATH 
 EXPOSE 1099 7000 50000 
 ENTRYPOINT $ JMETER_HOME / bin / jmeter-server -Djava.rmi.server.hostname = $ LOCALIP 
  

---

这是我如何创建一个容器

  sudo docker run -dit -e LOCALIP = '10 .11 .12.13'-p 7000：7000 -p 1099：1099 -p 50000：50000mydockerimg/ bin / bash 
  

我不明白这里发生了什么！我应该如何解决这个问题？

更新：根据@arcticless建议尝试

解决方案

尝试运行您的容器， -net =主机，不显示任何端口。应该工作 sudo docker run --net = host -dit -e LOCALIP ='your_ip'mydockerimg/ bin / bash


I am trying to do a distributed load testing using JMeter in AWS EC2 instances.

I have 1 master and 2 slaves. All are ubuntu instances. They all have java and jmeter installed.

I am able to successfully execute the test in the slaves w/o issues. (When i do no use docker) (JMeter uses RMI to control slaves)

Now, I am thinking of using docker in the slaves as I might be adding more slaves. I do not want to set up the slave machines everytime. So docker seems to be a good choice.

In the docker container, everything seems to be correct, all the necessary ports are open.

Issue:

Whenever I use docker container to run the jmeter-server in the slave, if i try to connect to it from the master, It throws java.net.connectexception connection refused connect <ip address> error.

If I telnet from the master to slave, it is able to connect successfully.

My dockerfile:

FROM ubuntu
RUN apt-get update
RUN apt-get -y install wget
RUN apt-get -y install default-jre
RUN mkdir /jmeter
RUN cd /jmeter/ ; wget http://www.us.apache.org/dist//jmeter/binaries/apache-jmeter-2.13.tgz ; tar -xzf apache-jmeter-2.13.tgz ; rm apache-jmeter-2.13.tgz
ENV JMETER_HOME /jmeter/apache-jmeter-2.13/
ENV PATH $JMETER_HOME/bin:$PATH
EXPOSE 1099 7000 50000
ENTRYPOINT $JMETER_HOME/bin/jmeter-server -Djava.rmi.server.hostname=$LOCALIP

This is how i create a container

sudo docker run -dit -e LOCALIP='10.11.12.13' -p 7000:7000 -p 1099:1099 -p 50000:50000 "mydockerimg" /bin/bash

I do not understand what is happening here!! How should i fix this?

---

UPDATE: Tried as per @arcticless suggestion

解决方案

Try running your container with the flag --net=host and without exposing any port. It should work. sudo docker run --net=host -dit -e LOCALIP='your_ip' "mydockerimg" /bin/bash
