k8s部署python-cx-Oracle缺少库

从 miniconda/centos7 构建 镜像

问题1 ：

Cannot locate a 64-bit Oracle Client libray "libclnsh.so" cannot open shared object file :No such file or direcory

解决方案：

RUN wget https://download.oracle.com/otn_software/linux/instantclient/instantclient-basiclite-linuxx64.zip && \
    unzip instantclient-basiclite-linuxx64.zip && \
    rm -f instantclient-basiclite-linuxx64.zip && \
    cd instantclient* && \
    rm -f *jdbc* *occi* *mysql* *jar uidrvci genezi adrci && \
    echo /opt/oracle/instantclient* > /etc/ld.so.conf.d/oracle-instantclient.conf && \
    ldconfig

建议做法：在本地下载后，删除部分文件，dockerfile 里面将这个instantclient* 拷贝到镜像，执行
echo /opt/oracle/instantclient* > /etc/ld.so.conf.d/oracle-instantclient.conf && ldconfig。

问题2：

 error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

解决方案：
64位系统安装：
将libaio-0.3.107-10.el6.x86_64.rpm CP到镜像里面，然后dockerfile里 执行rpm rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm

wget http://mirror.centos.org/centos/6/os/x86_64/Packages/libaio-0.3.107-10.el6.x86_64.rpm
rpm -ivh libaio-0.3.107-10.el6.x86_64.rpm

libaio-0.3.107-10.el6.x86_64.rpm 和 instantclient-basiclite-linuxx64.zip 可通过下面链接下载
