Docker 镜像的导入和导出的相关文章

docker镜像文件导入与导出

工作中经常需要拉取一些国外的镜像,但是网络限制等原因在公司拉取很慢,所以我习惯用亚马逊服务器拉取镜像,导出后下载到本地再导入开发环境 1. 查看镜像id sudo docker images REPOSITORY TAG IMAGE ID CREATED SIZE quay.io/calico/node v1.0.1 c70511a49fa1 6 weeks ago 257 MB hello-world latest 48b5124b2768 2 months ago 1.84 kB quay.

Docker 镜像-管理-导入-导出

目录 Docker 镜像基本概念 Docker 镜像加速 Docker 镜像 常用命令 Docker 镜像的创建和导出导入 Docker 镜像基本概念 我们使用的容器都是基于镜像的,镜像是由多层组成的,容器是在镜像上面添加了一个读写层.镜像一般储存在 /var/lib/docker/image/. 多个容器是引用的同一个 镜像,容器不会更改镜像的内容,而是创建一个可写层,并将数据保存在 /var/lib/docker/containers 中. Docker 镜像加速 当我们在使用 Docker

Docker镜像的导入导出

导入/导出命令介绍 导入/导出的功能主要用于Docker镜像的导入导出,用于迁移.备份.升级等场景,或者为隔离且没有私有镜像仓库环境添加docker镜像. 导入/导出的命令主要有下面几个:export.import.save.load,可以分为2组: save和load export和import 下面分别看看他们的用法和区别 save和load 命令用法 [email protected] -> ~/manifests$ docker save --help Usage: docker sav

Docker 容器的导入和导出操作

导出容器 导出容器是指 导出一个已经创建的容器到一个文件,不管此时这个容器是否处于运行状态,可以使用docker export 命令,该命令格式为 docker export CONTAINER. 查看所有容器如下: # docker ps -a CONTAINER ID        IMAGE                COMMAND             CREATED             STATUS                          PORTS       

docker镜像容器导入导出

记录一下,省的以后自己老忘. ubuntu-14.04-x86_64.tar.gz是下载的模板文件,导入模板文件示例如下 [email protected]:~# ll ubuntu-14.04-x86_64.tar.gz  -rw-r--r-- 1 root root 154056446 May 17 10:04 ubuntu-14.04-x86_64.tar.gz [email protected]:~# cat ubuntu-14.04-x86_64.tar.gz | docker imp

保存镜像文件或容器作为一个压缩的文件,和别人进行共享.导出一个容器作为一个tar文件. [[email protected] ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 8c892f17fc59 ubuntu:14.04 "/bin/bash" 6 minutes ago Exited (0) 5 minutes ago adoring_ardinghelli 90d654f31d93 u

Docker镜像批量导入

作用 主要目的用于批量镜像导入; 1.支持传参数导入 实例: sh import.sh "pause_3.1.tar etcd_3.3.10.tar" 注意:多个tar文件使用空格分隔; 2.支持脚本定义导入镜像名称 实例: vi import.sh STATE="ImgName1 ImgName2 ImgName3 ...." sh import.s 3.支持指定目录导入镜像 实例: vi import.sh TARDIR="/usr/local/bak

Docker 镜像批量备份（导出）

脚本作用 1.批量导出Docker Images;2.部分导出,通过指定Docker Images ID 到脚本"LIST"变量 运行实例 #导出全部的镜像: sh ExportImg.sh #导出部分镜像 LIST=" d235b 201c7a 201c7a" sh ExportImg.sh 注意:LIST赋值Docker Images ID ,多个镜像ID通过空格隔离:执行脚本是只会导出定义ID的镜像: 镜像还原(任选一种) docke load --input
