安装cx-Oracle包时候注意事项，先安装client

RUN mkdir -p /product/oracle/client

RUN cd /product/oracle/client && wget https://download.oracle.com/otn_software/linux/instantclient/195000/oracle-instantclient19.5-basic-19.5.0.0.0-1.x86_64.rpm && rpm -ivh oracle-instantclient19.5-basic-19.5.0.0.0-1.x86_64.rpm

RUN /root/.pyenv/shims/pip install cx-Oracle

命令行创建镜像

docker build -t linux_python:3.6.8 .

使用新的镜像打包服务dockerfile示例

FROM linux_python:3.6.8

RUN rm /bin/sh && ln -s /bin/bash /bin/sh

RUN mkdir -p /home/admin/blog

WORKDIR /home/admin

COPY ./ /home/admin/blog
