gunicorn

需要安装gunicorn gevent **注意！**这个模块虽然在win上可以使用pip进行安装，但是在win上是无法使用的，在linux环境下才可以使用！

Docker打包发布

使用Vscode自动生成Dockerfile

Dockerfile
# For more information, please refer to https://aka.ms/vscode-docker-python
FROM python:3.8-slim

EXPOSE 5002

# Keeps Python from generating .pyc files in the container
ENV PYTHONDONTWRITEBYTECODE=1

# Turns off buffering for easier container logging
ENV PYTHONUNBUFFERED=1

# 复制模块安装文件到目录中
COPY requirements.txt .
#换清华源
RUN python -m pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple
#设置工作目录
WORKDIR /app
#复制所有文件到工作目录
COPY . /app

# Creates a non-root user with an explicit UID and adds permission to access the /app folder
# For more info, please refer to https://aka.ms/vscode-docker-python-configure-containers
RUN adduser -u 5678 --disabled-password --gecos "" appuser && chown -R appuser /app
USER appuser

# During debugging, this entry point will be overridden. For more information, please refer to https://aka.ms/vscode-docker-python-debug
# 使用gunicorn启动项目在5002上
CMD ["gunicorn", "--bind", "0.0.0.0:5002", "wanAlert:app"]

将Dockerfile和项目文件都复制到同一目录下后

bash
[root@localhost flask]# docker build -t flask_app .
#查看镜像文件
[root@localhost flask]# docker images
#运行下看一下是否有错误
[root@localhost flask]# docker run <imageName>
#登入docker hub准备进行上传
[root@localhost flask]# docker login -uname -p
#上传至服务器
[root@localhost flask]# docker push <imageName>
#到正式服务器上后先登录 后pull下来，然后运行
[root@it-monitoring flask]$ docker run -d  -p5000:5002 <imageName>
