制作memcached镜像的dockfile如下：

FROM registry.acs.aliyun.com/open/centos:3.0.0
  
RUN cd /acs/user && \
  wget http://memcached.org/files/memcached-1.4.22.tar.gz && \
  tar -xzf memcached-1.4.22.tar.gz && \
  rm  -rf memcached-1.4.22.tar.gz && \
  mv memcached-1.4.22 memcached && \
  cd memcached && \
  ./configure --prefix /acs/user/memcached/ && \
  make && make install && \
  echo "export PATH=$PATH:/acs/user/memcached/bin/" > /root/.bash_profile && \
  echo "export PATH=$PATH:/acs/user/memcached/bin/" > /acs/user/.bash_profile
  
COPY check /acs/bin/check
COPY start /acs/bin/start

start脚本如下：

#!/bin/bash
env_file=/acs/conf/env.properties
#read env
if [ -f $env_file ];then
    port="$(cat $env_file |grep -w port.mainport|awk -F "=" '{print $2}')"
    memory="$(cat $env_file |grep -w memcached.memory|awk -F "=" '{print $2}')"
    connection="$(cat $env_file |grep -w memcached.connection|awk -F "=" '{print $2}')"
    thread="$(cat $env_file |grep -w memcached.thread|awk -F "=" '{print $2}')"
fi
#set default
if [ -z "$port" ];then
    port=11211
fi
if [ -z "$memory" ];then
    memory=500
fi
if [ -z "$connection" ];then
    connection=1024
fi
if [ -z "$thread" ];then
    thread=4
fi
CMD="/acs/user/memcached/memcached -u root -p $port -m $memory -c $connection -t $thread "
#start memcached
echo "################################### Start Memcached ###################################"
echo "Start command : $CMD "
$CMD &

check脚本如下

#!/bin/bash
if [ "`ps aux|grep memcached|grep -v grep|wc -l`" -eq 0  ];then  
        echo "failed" 
        exit 1
fi
echo "success"
 
exit 0
