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
