我正在学习如何在 Django 中使用 docker。所以第一步是你设置Dockerfile和这里是文件的内容。

FROM python:3.8.0-alpine

# set work directory
WORKDIR /usr/src/app

# set environment variables
ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

# install dependencies
RUN pip install --upgrade pip
COPY ./requirements.txt /usr/src/app/requirements.txt
RUN pip install -r requirements.txt

# copy project
COPY . /usr/src/app/

另一个文件docker-compose.yml下面的文件内容

version: '3.7'

services:
  web:
    build: ./project
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - ./project/:/usr/src/app/
    ports:
      - 8000:8000
    env_file:
      - ./.env.dev

现在这两个文件位于文件夹中，该文件夹docker还有我的 django 项目文件夹，称为project保持简单:)

当我运行时，docker-compose build我得到了错误 …

试图在gunicorn上运行两个站点来编辑服务

我有一个 keras 模型，其布局如下

def keras_model(x_train, y_train, x_test, y_test):
    model = Sequential()
    model.add(Dense(128, input_dim=x_train.shape[1], activation='relu'))
    model.add(Dense(256,activation='relu'))
    model.add(Dense(512,activation='relu'))
    model.add(Dense(256,activation='relu'))
    model.add(Dense(128,activation='relu'))
    #model.add(Dense(10,activation='relu'))
    model.add(Dense(y_train.shape[1], activation='softmax'))
    model.compile(loss='categorical_crossentropy', optimizer='adam')
    monitor = EarlyStopping(monitor='val_loss', min_delta=1e-3, patience=5, verbose=1, mode='auto')
    checkpointer = ModelCheckpoint(filepath="best_weights.hdf5", verbose=0, save_best_only=True) # save best model

    model.fit(x_train ,y_train, validation_data=(x_test, y_test),callbacks=[monitor,checkpointer], verbose=2,epochs=1000)
    model.load_weights('best_weights.hdf5') # load weights from best model

    return model

使用来自开放式健身房推杆游戏的数据进行训练，并保存模型。下一步是使用训练好的模型进行预测

from keras.models import load_model
model = load_model('data/model-v0.h5')
action = random.randrange(0,2)

import gym
env = gym.make("CartPole-v0")
env.reset()
>>> array([ 0.02429215, -0.00674185, -0.03713565, -0.0046836 ])

import random
action …

我正在设置一个 django 项目并尝试将 docker 与它一起使用。它可能依赖于使用 postgis 的 gdal。

这是docker文件

FROM python:3

ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY . /code/
RUN pip install -r requirements.txt

和需求文件

Django==2.1.5
psycopg2==2.7.6.1
gdal==2.2.3

当它到达 gdal 时，它会抛出此错误

FileNotFoundError: [Errno 2] No such file or directory: 'gdal-config': 'gdal-config'

但是这是我已经在本地工作的东西

(pw) sam@sam-Lenovo-G51-35:~/code/pw$ gdal-config --version
2.2.3

我确实尝试查看是否可以gdal-config通过将 docker 文件编辑为此来使用 run进行设置

FROM python:3

ENV PYTHONUNBUFFERED 1
RUN mkdir /code
RUN apt-get install libgdal-dev
RUN export CPLUS_INCLUDE_PATH=/usr/include/gdal
RUN export C_INCLUDE_PATH=/usr/include/gdal
WORKDIR /code
COPY . /code/
RUN …

尝试将文件从一个服务器rsync到另一个服务器获取

ubuntu@xx-xxx-xx-xx-xx:~$ rsync -i "xxxxxXXX.pem" -anv webapps ubuntu@xx.xx.xxx.xx:/home/ubuntu/
Permission denied (publickey).
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(226) [sender=3.1.1]

我可以用ssh进入服务器 ssh -i "xxxxxxx.pem" ubuntu@xx.xxx.xxx.xx

密钥的权限是 600

-rw-------  1 ubuntu ubuntu    1696 Feb  1 06:00 xxxxxxxx.pem

我正在尝试django-location-field使用python3安装在Django 2.1.2版上。我将其安装并添加location_field.apps.DefaultConfig到设置中，然后弹出错误消息提示缺少的软件包gdal。

错误
