Question

我需要在 docker 镜像中安装一些 python 包并将该镜像部署为 kubernetes 部署。下面是我的 Dockerfile 和部署文件

FROM python:3.7-slim

# install FreeTDS and dependencies
RUN apt-get update \
 && apt-get install unixodbc -y \
 && apt-get install unixodbc-dev -y \
 && apt-get install freetds-dev -y \
 && apt-get install freetds-bin -y \
 && apt-get install tdsodbc -y \
 && apt-get install --reinstall build-essential -y

# populate "ocbcinst.ini"
RUN echo "[FreeTDS]\n\
Description = FreeTDS unixODBC Driver\n\
Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so\n\
Setup = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so" >> /etc/odbcinst.ini

# install pyodbc (and, optionally, sqlalchemy)
RUN pip install --trusted-host pypi.python.org pyodbc==4.0.26 sqlalchemy==1.3.5 pyarrow

# run app.py upon container launch
CMD ["python3"]

docker 镜像构建命令

docker build pyarrow-custom:latest .

apiVersion: apps/v1
kind: Deployment
metadata:
  name: python-odbc-custom
  labels:
    app: python-odbc-custom
spec:
  replicas: 1
  selector:
    matchLabels:
      app: python-odbc-custom
  template:
    metadata:
      name: python-odbc-custom
      labels:
        app: python-odbc-custom
    spec:
      containers:
        - name: python-odbc-custom
          image: "pyarrow-custom:latest"
          command: ['python3']
          imagePullPolicy: IfNotPresent
          ports:
            - name: http
              containerPort: 8099

kubectl 命令

kubectl apply -f python-obbc-deployment.yaml

但是，在创建容器之后，它就完成了。当我在 CMD 中给出 python3 时，我想继续在那里运行 python shell。我该怎么做？

Kubernetes 为 python shell 部署 python 镜像
