docker

Why

开箱即用

环境隔离

proxy

# user (works)
mkdir -p ~/.docker
vim ~/.docker/config.json
# sudo
sudo vim /etc/docker/daemon.json

dockerfile vs docker compose

dockerfile 管理单个容器的一步步构建应用程序的流程；

docker compose 管理多个容器之间启动与配置；

Note

docker compose 不可以替代 dockerfile，因为 >docker compose 总是依赖 dockerfile 打包好的文件。
