Docker鏡像制作
以創(chuàng)建一個新ubuntu鏡像，并安裝vim命令示例
運(yùn)行一個ubuntu鏡像，發(fā)現(xiàn)在鏡像里面無法使用vim命令，因為該ubuntu鏡像只包括了其最基本的內(nèi)核命令
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
ubuntu latest ba6acccedd29 2 years ago 72.8MB
[root@localhost ~]# docker run -it ba6acccedd29 /bin/bash
root@f1e088df465f:/# vim a.txt
bash: vim: command not found
給ubuntu容器安裝vim
root@f1e088df465f:/# apt-get update
root@f1e088df465f:/# apt-get -y install vim安裝完成之后就可以在容器里面使用vim編輯器進(jìn)行文件的編輯了
root@f1e088df465f:/# vim a.txt
root@f1e088df465f:/#
將這個運(yùn)行的容器制作成一個帶有vim功能的ubuntu鏡像
docker commit -m="提交的描述信息" -a="作者" 容器ID 要創(chuàng)建的目標(biāo)鏡像名:[標(biāo)簽名][root@localhost ~]# docker commit -m="add vim" -a="mgaw" f1e088df465f linux1:1.00001
sha256:6eb1515df77a8a00c6ae3ff5c541f26a50fd585a4b67d321280612cef1f852e1
查看鏡像，發(fā)現(xiàn)比原鏡像大了很多
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
linux1 1.00001 6eb1515df77a 31 seconds ago 189MB
ubuntu latest ba6acccedd29 2 years ago 72.8MB
運(yùn)行自己制作的鏡像
[root@localhost ~]# docker run -it 6eb1515df77a /bin/bash
root@cc4ba90ce5d4:/# vim a.txt
root@cc4ba90ce5d4:/#
發(fā)現(xiàn)確實帶有vim功能了
搭建私服
下載鏡像Docker Registry
[root@localhost ~]# docker pull registry
運(yùn)行私服庫Registry，相當(dāng)于本地的私有Docker hub
[root@localhost ~]# docker run -d -p 5000:5000 -v /mgaw/myregistry/:/tmp/registry --privileged=true registry

將本地鏡像推送到私服
以創(chuàng)建一個新ubuntu鏡像，并安裝ifconfig命令示例
運(yùn)行一個ubuntu鏡像，發(fā)現(xiàn)在鏡像里面無法使用ifconfig命令，因為該ubuntu鏡像只包括了其最基本的內(nèi)核命令

使用
curl
工具驗證私服庫上有什么鏡像
[root@localhost ~]# curl -XGET http://192.168.117.131:5000/v2/_catalog
{"repositories":[]}
目前私服庫沒有鏡像上傳過
將新鏡像
ubuntu1:1.00002
修改符合私服規(guī)范的
Tag
命令格式： docker tag 鏡像:Tag Host:Port/Repository:Tag
[root@localhost ~]# docker tag ubuntu1:1.00002 192.168.117.131:5000/ubuntu1:1.00002

http
vim /etc/docker/daemon.json新增如下內(nèi)容
"insecure-registries": ["192.168.117.131:5000"]最后的結(jié)果如下
?重新啟動docker，并保證linux防火墻沒有對5000端口攔截
[root@localhost ~]# systemctl restart docker
由于重新啟動了docker，需要重新啟動
docker registry
容器
[root@localhost ~]# docker run -d -p 5000:5000 -v /mgaw/myregistry/:/tmp/registry --privileged=true registry

推送鏡像到私服
[root@localhost ~]# docker push 192.168.117.131:5000/ubuntu1:1.00002
The push refers to repository [192.168.117.131:5000/ubuntu1]

[root@localhost ~]# curl -XGET http://192.168.117.131:5000/v2/_catalog
