该镜像包主要安装CDH 的daemons，agent服务

1. 创建并运行基础容器

启动基础容器，在此基础上安装agent-server所需的软件

docker run -d \
--hostname agentserver \
--name agentserver \
--privileged=true \
server/bashimage  \
/usr/sbin/init \
&& docker ps

结果：
9bba31143dcf70a4775a7d20085ea277f940f67e132cfe9b8d7001fa92189d87
CONTAINER ID   IMAGE              COMMAND            CREATED                  STATUS                  PORTS     NAMES
9bba31143dcf   server/bashimage   "/usr/sbin/init"   Less than a second ago   Up Less than a second   22/tcp    agentserver

2. 初始化容器环境

# 进入容器
docker exec -it --privileged=true agentserver /bin/bash 
 
# 初始化容器环境
ping www.baidu.com -c 3 \
&& yum update -y \
&& yum install -y openssh-clients kde-l10n-Chinese telnet reinstall glibc-common wget ntp net-tools firewalld httpd unzip \
&& yum clean all 
 
结果：
PING www.a.shifen.com (180.101.49.11) 56(84) bytes of data.
64 bytes from 180.101.49.11 (180.101.49.11): icmp_seq=1 ttl=127 time=54.7 ms

64 bytes from 180.101.49.11 (180.101.49.11): icmp_seq=3 ttl=127 time=87.8 ms...

3. 关闭防火墙

systemctl stop firewalld \
&& systemctl disable firewalld \
&& systemctl status firewalld 

结果：
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

4. 配置中文环境

(
cat <<EOF
export LC_ALL=zh_CN.utf8
export LANG=zh_CN.utf8
export LANGUAGE=zh_CN.utf8
EOF
) >> ~/.bashrc \
&& localedef -c -f UTF-8 -i zh_CN zh_CN.utf8 \
&& source ~/.bashrc \
&& echo $LANG

结果：
zh_CN.utf8

5. 配置httpd ，新增yum源

此步骤是为了离线安装CDH的JDK，daemons ，agent

systemctl start httpd \
&& systemctl enable httpd \
&&(
cat <<EOF
[cloudera-manager]
name=Cloudera Manager 6.3.1
baseurl=http://172.16.0.2/cloudera-repos/
gpgcheck=0
enabled=1
EOF
) >> /etc/yum.repos.d/cloudera-manager.repo \
&& curl http://172.16.0.2/cloudera-repos/ \
&& yum clean all

结果：

6. 安装JDK，daemons ，agent

yum install -y oracle-j2sdk1.8 cloudera-manager-daemons cloudera-manager-agent \
&& rpm -qa | grep cloudera-manager \
&& (cat <<\EOF
export JAVA_HOME=/usr/java/jdk1.8.0_181-cloudera
export PATH=$PATH:$JAVA_HOME/bin
EOF
) >> ~/.bashrc \
&& source ~/.bashrc \
&& java -version

结果:
Complete!
cloudera-manager-agent-6.3.1-1466458.el7.x86_64
cloudera-manager-daemons-6.3.1-1466458.el7.x86_64
java version "1.8.0_181"
Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
未出现上诉一模一样的结果，请重新执行一遍（cloudera-manager-daemons有点难装 ）

7. 修改agent配置

server_host 是CDH master-server的hostname，也就是master-server容器的主机名，根据现场情况修改

不然会导致CDH master-server找不到agent服务

sed -i 's/server_host=localhost/server_host=server001/g' /etc/cloudera-scm-agent/config.ini \
&& grep "server_host" /etc/cloudera-scm-agent/config.ini

结果：
server_host=server001

到这为止，agent-server容器已经安装了JDK，CDH的daemos，agent服务，只是安装好，并没有启动也无需启动。开始打成镜像包做备份

8. 将容器提交成镜像

接下来将agent-server容器打包成镜像。

该容器可以重复使用，CDH集群需要多个agent服务，启动相应数量的agent-server容器即可

# 停止asrserver00x容器,提交为镜像,查看镜像，打包镜像
docker stop agentserver \
    && docker commit agentserver agent-server/cdh:6.3.2 \
    && docker images \
    && docker save -o /root/agent-server.tar.gz agent-server/cdh:6.3.2 \
    && ls -l --block-size=M

# 结果
agentserver

深入理解 Mocha 测试框架：从零实现一个 Mocha

前言什么是自动化测试自动化测试在很多团队中都是Devops环节中很难执行起来的一个环节，主要原因在于测试代码的编写工作很难抽象，99%的场景都需要和业务强绑定，而且写测试代码的编写工作量往往比编写实际业务代码的工作量更多。在一些很多业务场景中投入产出比很低，适合写自动化测试的应该是那些中长期业务以及一些诸如组件一样的基础库。自动化测试是个比较大的概念，其中分类也比较多，比如单元测试，端对端测试，集

(20200916 Solved)docker-compose up创建容器自动退出

问题描述如题，创建容器后自动退出了。并且docker start container无效解决方案原因是缺失了控制终端的配置，需要在docker-compose.yml中增加tty:true ，有时候这样也不行，需要再增加一个command:/bin/bash，命令不一定是这个，需要是一个不会退出的命令，然后用-d后台启动容器。Referencesdocker-compose启动容器后自动退出...
