docker docker制作tar docker基於運行的容器制作鏡像
推送鏡像
3.1.推送到docker-hub(需要註冊一個dockerhub賬號)
鏡像構建:
docker commit 【option】
-a 指明作者
-p 暫停容器再建立鏡像
[root@vichost ~]# docker commit -p -a "vicliaoxz <[email protected]>" centos2 sha256:ead743182b50ba021d5eee144aad229cbcf093f6796363b11e366f6117a62fab [root@vichost ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE <none> <none> ead743182b50 About a minute ago 302 MB [root@vichost ~]# docker run -it --name c-net-tools ead743182b50 [root@ff3b674ffa51 /]# ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 172.17.0.4 netmask 255.255.0.0 broadcast 0.0.0.0 inet6 fe80::42:acff:fe11:4 prefixlen 64 scopeid 0x20<link>
給鏡像添加標簽
docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG] [root@vichost ~]# docker tag ead743182b50(ID) vicdockerhub(用戶名)/centos(基礎鏡像):net-tools(標簽) [root@vichost ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE vicdockerhub/centos net-tools ead743182b50 21 minutes ago 302 MB
3.1.推送到docker-hub(需要註冊一個dockerhub賬號)
[root@vichost ~]# docker login -u vicdockerhub
Password:
Login Succeeded
[root@vichost ~]# docker push vicdockerhub/centos:net-tools
The push refers to a repository [docker.io/vicdockerhub/centos]
3.2.上傳到私有倉庫:docker tag vicdockerhub/centos:net-tools myregistry.liaoxz.xin:5000/vicdockerhub/centos:net-tools
- 將鏡像保存為tar包
docker ecport 導出為一個容器Usage: docker save [OPTIONS] IMAGE [IMAGE...] Options: -o, --output string Write to a file, instead of STDOUT
[root@vichost ~]# docker save vicdockerhub/centos:net-tools -o centos-net-tools.tar
[root@vichost ~]# ls
centos-net-tools.tar
5. 外部tar包導入鏡像
docker load
docker load -i 指定鏡像tar包
[root@vichost ~]# docker load -i centos-net-tools.tar
Loaded image: vicdockerhub/centos:net-tools
[root@vichost ~]# docker images
