我正在尝试连接在 docker 容器中运行的 pyodbc python 脚本以登录到 MSSQL 数据库我尝试了各种 docker 文件，但无法建立连接（在构建 docker 或 python 尝试连接时失败） ），有没有人有一个可用的 dockerfile，使用 pyodbc：
Dockerfile：
# Use an official Python runtime as a parent image
FROM python:2.7-slim
# Set the working directory to /app
WORKDIR /app
# Copy the current directory contents into the container at /app
ADD . /app
# Install any needed packages specified in requirements.txt
RUN pip install -r requirements.txt
# Run app.py when the container launches
CMD ["python", "App.py"]
要求.TXT
pyodbc
App.Py
import pyodbc
connection = pyodbc.connect('Driver={SQL Server};'
'Server=xxxx;'
'Database=xxx;'
'UID=xxxx;'
'PWD=xxxx')
cursor = connection.cursor()
cursor.execute("SELECT [Id],[Name] FROM [DCMM].[config].[Models]")
for row in cursor.fetchall():
print(row.Name)
connection.close()
构建容器 docker build -t sql test 。
