docker run error : DPI-1047: Cannot locate a 64-bit Oracle Client library

Question

我正在尝试将一个非常简单的 python 应用程序与 Oracle 数据库连接并在 Docker 上执行它。此应用程序在我的本地计算机上运行良好。

我能够成功构建此应用程序，但在 Docker 上执行时出现错误。

Docker文件:

FROM python:3

ADD File.py /

RUN pip install cx_Oracle
RUN pip install pandas
RUN pip install openpyxl

CMD [ "python", "./File.py" ]

File.py:

import cx_Oracle
import pandas as pd

#creating database connection
dsn_tns = cx_Oracle.makedsn('dev-tr01.com', '1222', service_name='ast041.com')
conn = cx_Oracle.connect(user=r'usr', password='3451', dsn=dsn_tns)
c = conn.cursor()

query ='SELECT * FROM Employee WHERE ROWNUM <10'
result = pd.read_sql(query, con=conn)
result.to_excel("batchtable.xlsx")

conn.close()

错误：

docker run python_batchdriver:latest

cx_Oracle.DatabaseError: DPI-1047: Cannot locate a 64-bit Oracle Client library: "libclntsh.so: cannot open shared object file: No such file or directory". See https://oracle.github.io/odpi/doc/installation.html#linux for help

对于 cx_Oracle，您还需要安装 Oracle Instant Client 库。见 cx_Oracle installation instructions.

在 Docker 中有多种自动安装的方法。一个例子是：

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

您还需要 libaio 或 libaio1 软件包。

参见Docker for Oracle Database Applications in Node.js and Python。
