Docker images are the basis of containers. An Image is an ordered collection of root filesystem changes and the corresponding execution parameters for use within a container runtime. An image typically contains a union of layered filesystems stacked on top of each other. An image does not have...

安装完docker环境之后就是使用docker了,我学习一般喜欢先“知其然”,就是学会用这个东西,然后再“知其所以然”,了解这个技术背后的架构和原理,而使用docker首先就要弄明白image和container。 Docker Image Image简介 1. Image是文件和Metadata的集合(root filesystem) ...
DiffID是制作镜像时针对每层产生的hash值,可以通过命令docker image inspect查看字段中的RootFS.Layers拿到DiffID哈希值(默认排序:第一行则是最底层,由底层往上排序)。 ChainID是通过计算公式得出的ID,作用是与CacheID对应的层做内容寻址的索引,进而关联到每一个镜像层的镜像文件。对应的目录是/var/lib/docker/image...
docker inspect:获取容器的详细信息,包括配置和状态,是调试的强有力工具。docker kill:向容器发送信号,通常用于紧急终止容器运行。docker pause:暂停容器中的所有进程,而不停容器,适用于临时冻结容器状态。docker port:列出容器的端口映射关系,帮助我们了解容器的网络配置。docker prune:清理所有未使用的容器、镜像、网络...
