当我们在 myproject 下放置一个与程序无关的大文件(或无关小文件,如应用构建的依赖包等)时,重新构建 helloapp:v3 时发现需要传输 70 MB的内容到服务端,并且镜像大小到 71MB。#5 [internal] load build context#5 sha256:746b8f3c5fdd5aa11b2e2dad6636627b0ed8d710fe07470735ae58682825811f#5 transferrin...

CMD python /app/app.py 它的核心逻辑是定义引用的基础镜像 base image,执行如 COPY 指令从上下文 context 里复制文件到容器中,运行 RUN 执行用户自定义构建脚本,最后定义容器启动的 CMD 或 ENTRYPOINT。构建更高效的镜像也要围绕上述涉及到的概念进行优化。

多数情况下CMD 都需要一个交互式的 shell (bash,Python, perl 等),例如 CMD [“perl”, “-de0”],或者 CMD [“PHP”, “-a”]。使用这种形式意味着,当你执行类似docker run -it python时,你会进入一个准备好的 shell 中。 代码语言:javascript ...
Compose允许用户通过一个单独的docker-compose.yml模板文件(YAML 格式)来定义一组相关联的应用容器为一个项目(project)。 Docker-Compose项目由Python编写,调用Docker服务提供的API来对容器进行管理。因此,只要所操作的平台支持Docker API,就可以在其上利用Compose来进行编排管理。 Docker-Compose将所管理的容器分为三层,...
