1、docker for windows推荐使用WSL22、安装完成后,image默认存储位置是C:\Users\${用户名}\AppData\Local\Docker\wsl\data\ext4.vhdx3、如果需要修改image存储位置:wsl --export docker-desktop-data D:\docker-desktop-data.tar 备份原始数据,一定要做
wsl --unregister docker-desktop-data 删除原始数据
wsl --import docker-desktop-data X:\path\to X:\path\to\docker-desktop-data.tar --...
docker images往往不知不觉就占满了硬盘空间,为了清理冗余的image,可采用以下方法:1.进入root权限sudo su2.停止所有的container,这样才能够删除其中的images:docker stop $(docker ps -a -q)如果想要删除所有container的话再加一个指令:docker rm $(docker ps -a -q)3.查看当前有些什么imagesdocker images4.删除images,通过image的id来指定删除谁docker rmi <image id>想要删除untagged images,也就是那些id为<None>的ima...

我们常常会基于某个image来启动一个container,在这个container中我们可能会执行某些操作,比如创建一个文件,但是当这个container退出以后,如果我们以同一个的image启动了另一个container,在这个container中是看不到之前那个container创建的文件的,如果想让后面的container看到之前那个container创建的文件,就要把之前那个container保存成一个镜像,然后基于这个镜像来启动后面的那个container,举个简单的例子:(假设我们都...
Learn the benefits of running one-off, short-lived Docker containers. Short-Lived containers are useful to execute one-line commands or setup scheduled tasks. We‘ll demonstrate setting up a cronjob from the host machine to tap into the benefits of running automated, timed scripts with Docker.docker --rm ngnix ngnix -h // run short live ngnix container with command ngnix -hThis command will run n...
这里主要介绍一下私有仓库(HTTPS)在Kubernetes中部署的问题,由于Kubernetes将弃用docker,因此这里主要介绍以下使用containerd替换docker后如何从私有仓库拉取镜像并完成镜像的部署。下载registry2.7.1的镜像文件说明:在使用registry2.3.1的话会有一个严重的问题,问题就是在yaml或者在命令行通过ctr和crictl命令拉取镜像时携带的sha256值和私有仓库中镜像存储的实际sha256不一致,因此会报找不到镜像的问题:not found: not fou...

image镜像Definition of: imageDocker 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 state and it never changes引用docker官网的定义,大意是:docker images是conta...
