我想念什么?

就像[Docker how to run pip requirements.txt only if there was a change?中接受的答案一样,在将整个应用程序添加到图像中之前,我已经在单独的构建步骤中复制了{{1}}文件,但是它似乎不起作用。
答案 0 :(得分:1)
尝试从复制的文件安装要求
https://docs.docker.com/develop/develop-images/dockerfile_best-practices/
这是其 Dockerfile
的一个示例COPY requirements.txt /tmp/
RUN pip install --requirement /tmp/requirements.txt
这就是你拥有的
RUN pip install -r requirements.txt
然后,在更改了docker文件之后,您必须停止容器,删除映像,构建新映像并从中运行容器。
停止容器并删除图像。
docker-compose down
docker-compose --rmi all
--rmi all
-删除所有图像。您可能要使用--rmi IMAGE_NAME
并启动它(如果不使用默认参数,请使用参数更改这些命令)。
docker-compose up
如果您正在运行docker并且不想停止它并重建映像(如果您只想安装软件包或运行某些命令甚至启动新应用程序),则可以从本地连接该容器机器和运行命令行命令。
docker exec -it [CONTAINER_ID] bash
要获取[CONTAINER_ID]
,请运行
docker ps
注意docker-compose ps
将为您提供容器名称,但是您需要使用容器ID来对容器进行SSH。
