Dockerfile 中的 Jboss 5.1 - 如何在浏览器中访问服务器

Question

我有一个看起来像这样的 dockerfile:

FROM ubuntu:trusty

RUN DEBIAN_FRONTEND=noninteractive apt-get -yq upgrade

# Update to latest
RUN echo "deb http://archive.ubuntu.com/ubuntu trusty main universe" > /etc/apt/sources.list
RUN echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" > /etc/apt/sources.list.d/webupd8team-java.list
RUN apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C2518248EEA14886

RUN apt-get update
RUN apt-get upgrade -y

# Install basics
# RUN apt-get install -y python-software-properties software-properties-common unzip
RUN apt-get install -y unzip


# Install Java, auto-accepting the license
# RUN add-apt-repository -y ppa:webupd8team/java
# RUN apt-get update
# RUN echo oracle-java6-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections
# RUN apt-get install -y oracle-java6-installer
RUN echo oracle-java6-installer shared/accepted-oracle-license-v1-1 select true | /usr/bin/debconf-set-selections

# Install different Java versions
RUN DEBIAN_FRONTEND=noninteractive apt-get install -yq oracle-java6-installer 

# Set environment variables pointing to different Java installations
ENV JAVA_HOME /usr/lib/jvm/java-6-oracle
ENV JAVA6_HOME /usr/lib/jvm/java-6-oracle


# Ensure Java 6 is the default version
RUN update-java-alternatives -s java-6-oracle

# Install JBoss 5.1.0.GA
RUN wget -O jboss.zip http://sourceforge.net/projects/jboss/files/JBoss/JBoss-5.1.0.GA/jboss-5.1.0.GA-jdk6.zip/download
RUN unzip jboss.zip && mv jboss-5.1.0.GA /opt
RUN cd /opt/jboss-5.1.0.GA/bin && chmod +x *.sh
CMD /opt/jboss-5.1.0.GA/bin/run.sh


# Clean-up to reduce the image size
RUN apt-get clean

EXPOSE 8080

我构建它而不是:

sudo docker build -t dockerfile .

一切都很好。所以我启动服务器:

sudo docker run -it --publish 127.0.0.1:8080:8080 dockerfile:latest

我可以看到服务器正确启动

如果我输入 URL 127.0.0.1:8080我有一个错误网站:

the connection was reset - the connection to the server was reset while the page was loading

如何在浏览器中连接到服务器？

我的容器的检查如下所示:

jottrs 回答后编辑:
日志说:

而已....

因为 Jottrs IP 提到:
据我了解，我将我的服务器绑定(bind)到 127.0.0.1:8080使用启动命令:

sudo docker run -it --publish 127.0.0.1:8080:8080 dockerfile:latest

如果我查看 ifconfig 我有 docker 文件正在运行:

$ ifconfig
docker0   Link encap:Ethernet  Hardware Adresse 56:84:7a:fe:97:99  
          inet Adresse:172.17.42.1  Bcast:0.0.0.0  Maske:255.255.0.0
          inet6-Adresse: fe80::5484:7aff:fefe:9799/64 Gültigkeitsbereich:Verbindung

          RX-Bytes:4983 (4.9 KB)  TX-Bytes:12056 (12.0 KB)

但与 $ sudo docker inspect --format "{{ .NetworkSettings.IPAddress }}" 054我得到 172.17.0.5
但是我的浏览器也没有与 URL 172.17.0.5:8080 的连接。或网址 172.17.42.1:8080
如果我从 $ sudo docker run -d --publish 172.17.42.1:8080:8080 dockerfile:latest 开始(ifconfig IP)我将无法建立连接(并且日志仍然没有反应)

$ sudo docker exec -it 228 bash
root@22870ce4265e:/# cat /etc/hosts
172.17.0.6  22870ce4265e
127.0.0.1   localhost

fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

Answer 1

问题是 JBoss 而不是 Docker。 JBoss 默认只监听 localhost:8080 Jboss only works on localhost:8080 ,but doesnt reply when called by ip (我不是 JBoss 人，所以您必须尝试“-b 0.0.0.0”或通过 ADD 在 Dockerfile 中提供 server.xml)。

当你运行时(在我的例子中，我调用了容器 jboss)

sudo docker exec jboss apt-get install curl -y 
sudo docker exec jboss curl localhost:8080

您注意到 JBoss 运行并且可以访问。
