# 定义日志函数
log() {
  echo -e "\e[$1m ========== $2 ========== \e[0m\n\n"
}


# 容器/镜像名称变量
if [ -n "$1" ]; then
    name=$1
else
    log 31 请输入镜像名称
    exit 1
fi



# 0.替换容器信息
echo -e "\n"
containerName=`docker ps | grep ${name%:*} | awk '{print $NF}'`
imageName=`docker ps | grep ${name%:*} | awk '{print $2}'`
echo -e "container-name -------- ${containerName}"
echo -e "image-name -------- ${imageName}"
log 32 被替换容器信息


# 1.创建镜像
docker build -t $name . || ! log 31 创建镜像失败：dockerfile文件与测试环境不一致 || exit
log 32 创建镜像成功


# 2.删除容器
docker ps -a | grep ${name%:*}
docker rm -f `docker ps -a | grep ${name%:*} | awk '{print $1}'`
log 32 删除容器成功


# 3.创建容器
context_num1=`cat -n /paasdata/imopscm/docker_run_commands_for_apps | grep "${name%:*}" |grep "service_name"| awk 'END {print $1}'`
context_num2=`cat -n /paasdata/imopscm/docker_run_commands_for_apps | grep "${name%:*}:" | awk 'END {print $1}'` 

num1=$((context_num1+1))
num2=$((context_num2-1))
run_commands=`sed -n "${num1},${num2}p" /paasdata/imopscm/docker_run_commands_for_apps`" ${name}"
run_commands=${run_commands//\\/ }
echo $run_commands
eval $run_commands
log 32 创建容器成功


# 4.查看容器状态
docker ps | grep ${name%:*}
log 32 服务正在启动，大概需要1分钟，请稍后...

while [ `docker ps | grep $name | grep starting | wc -l` -eq 1 ]; do
  :
done

docker ps | grep ${name%:*}
log 32 服务启动成功
