Docker建置Python筆記

建立資料夾  /share/Container/chi

新增檔案 Dockerfile

FROM python:3.11-slim

WORKDIR /app

# 安裝工具與 ODBC Driver

    curl gnupg apt-transport-https unixodbc-dev gcc g++ make \

docker build -t chi .

建立完成後，如果成功你就會看到有 chi 這個 image

接下來就可以用這個image來建置 flask

新增5099 port的flask，建立資料夾  /share/Container/chi5099，把 app.py 及 templates ( app.py 裡的port用5000 )

docker build -t chi .
docker run -d --name chi5099 \
  -p 5099:5000 \
  -v /share/Container/chi5099:/app \
  chi

由於範例要有連 pyodbc，因此有額外安裝 msodbcsql17，如果沒用到可以調整
