# 將一個鏡像保存爲一個鏡像文件。 root@db4:~# docker save -o nginx_v2.0.tar nginx:v2.0 root@db4:~# ls nginx_v2.0.tar # 將一個鏡像文件載入爲鏡像。 root@db4:~# docker load --input nginx_v2.0.tar 或 root@db4:~# docker load < nginx_v2.0.tar
22.導出容器和導入鏡像
將一個正在運行或者停止的容器導出爲一個容器文件 root@db4:~# docker export b96 > nginx.tar root@db4:~# ls nginx.tar 將一個容器文件導入到本地鏡像倉庫 root@db4:~# docker import nginx.tar nginx sha256:aaf9cb9f42047c24be3178c9205323175c0b872b3a695314e22ce1d432caa501 root@db4:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest aaf9cb9f4204 8 seconds ago 236 MB nginx v2.0 e8b6bdca34fd About an hour ago 236 MB registry.cn-hangzhou.aliyuncs.com/jonny/nginx 1.9.14 54f500f03701 8 months ago 236 MB
23.構建鏡像
root@db4:~# touch Dockerfile root@db4:~# vim Dockerfile root@db4:~# cat Dockerfile FROM registry.cn-hangzhou.aliyuncs.com/jonny/python:3 root@db4:~# docker build . Sending build context to Docker daemon 490.1 MB Step 1/1 : FROM registry.cn-hangzhou.aliyuncs.com/jonny/python:3 3: Pulling from jonny/python 5c90d4a2d1a8: Pull complete a3ed95caeb02: Pull complete 7aacfb932892: Pull complete 29b0204e3e44: Pull complete f7b3449113d2: Pull complete 4696148a3d89: Pull complete a65fc447ceea: Pull complete eebbb7c52ba8: Pull complete Digest: sha256:e047386633dad2226fbdb5d01f138cf648a6245ef1250e9d1a34e7c95454fda2 Status: Downloaded newer image for registry.cn-hangzhou.aliyuncs.com/jonny/python:3 ---> 7918f1fa1b61 Successfully built 7918f1fa1b61 root@db4:~# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest aaf9cb9f4204 7 minutes ago 236 MB nginx v2.0 e8b6bdca34fd About an hour ago 236 MB registry.cn-hangzhou.aliyuncs.com/jonny/nginx 1.9.14 54f500f03701 8 months ago 236 MB registry.cn-hangzhou.aliyuncs.com/jonny/python 3 7918f1fa1b61 10 months ago 686 MB
24.查看鏡像的歷史
root@db4:~# docker history nginx:v2.0
