SpringCloud(第 055 篇)CentOS7 搭建 docker-registry 私有库及管理界面
-一、大致介绍
1、基于前面docker的部署,容器一多非常不便于管理,于是急需一个自己的docker私有库; 2、而目前市面上大多数的私有库基本上都是后台服务加前台ui构成,于是选来选去,最后选择了portainer管理界面; 3、之所以选择portainer这款管理界面,我就简述阐述一下,基于以下几点综合考虑而为之: 3.1 DockerUI 无登录验证,无法权限分配,不支持多主机; 3.2 Shipyard 支持集群,支持权限分配,启动容器较多,占用每个节点的一部分资源; 3.3 Portainer 轻量级著称,消耗资源少,虽然功能没有Shipyard强大,但麻雀虽小五脏俱全,满足基本需求; 3.4 Daocloud 功能强大,部分高级功能收费,安装稍微难度大点,土豪公司无外乎都会选择此项; 4、注意:下面的 my_host_ip 字符串,请大家换成你们自己的宿主机ip地址即可;
二、docker-registry 安装步骤
2.1 搜索docker-registry镜像
// 利用docker搜索命令,看看能搜索包含registry字段的东西,能出来个啥东西 [root@svr01 ~]# docker search registry INDEX NAME DESCRIPTION STARS OFFICIAL AUTOMATED docker.io docker.io/registry The Docker Registry 2.0 implementation for... 1847 [OK] docker.io docker.io/konradkleine/docker-registry-frontend Browse and modify your Docker registry in ... 177 [OK] docker.io docker.io/hyper/docker-registry-web Web UI, authentication service and event r... 123 [OK] 。。。。。。 docker.io docker.io/convox/registry 0 docker.io docker.io/kontena/registry Kontena Registry 0 docker.io docker.io/lorieri/registry-ceph Ceph Rados Gateway (and any other S3 compa... 0 docker.io docker.io/mattford63/registry The officail docker-registry with python-m... 0
2.2 拉取docker.io/registry镜像
// 随便拉取了一个指定版本,也可以拉取下来 [root@svr01 ~]# docker pull docker.io/registry:2.3.1 Trying to pull repository docker.io/library/registry ... 2.3.1: Pulling from docker.io/library/registry fdd5d7827f33: Pull complete a3ed95caeb02: Pull complete a79b4a92697e: Pull complete 6cbb75c7cc30: Pull complete 4831699594bc: Pull complete Digest: sha256:9bd58f43fdf3c378ee7f19ec6e355a5ecbfad8eab82c77079b974b5a78b59e4d [root@svr01 ~]# [root@svr01 ~]# [root@svr01 ~]# [root@svr01 ~]# [root@svr01 ~]# // 获取一个最新的版本,只要网络畅通,基本上都能获取下来 [root@svr01 ~]# docker pull docker.io/registry Using default tag: latest Trying to pull repository docker.io/library/registry ... latest: Pulling from docker.io/library/registry 81033e7c1d6a: Pull complete b235084c2315: Pull complete c692f3a6894b: Pull complete ba2177f3a70e: Pull complete a8d793620947: Pull complete Digest: sha256:672d519d7fd7bbc7a448d17956ebeefe225d5eb27509d8dc5ce67ecb4a0bce54 [root@svr01 ~]# [root@svr01 ~]# [root@svr01 ~]# [root@svr01 ~]# [root@svr01 ~]# // 查看我们拉取的镜像是否都已经存在本地了 [root@svr01 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/registry latest d1fd7d86a825 3 weeks ago 33.26 MB springms/gateway-zuul latest f3825f14878c 6 weeks ago 248.5 MB springms/provider-user latest 5f8a95ffddae 6 weeks ago 270.6 MB springms/discovery-eureka latest 825e3f54be46 6 weeks ago 252.5 MB springms-simple-provider-user latest 7ccdcdd5270f 6 weeks ago 235.6 MB springms-user latest 4799ed153086 6 weeks ago 235.6 MB docker.io/centos v2 11efb35f320c 6 weeks ago 307.5 MB docker.io/frolvlad/alpine-oraclejdk8 latest 4f03dc990224 8 weeks ago 170.1 MB frolvlad/alpine-oraclejdk8 slim 4f03dc990224 8 weeks ago 170.1 MB docker.io/centos latest 3fa822599e10 8 weeks ago 203.5 MB docker.io/hello-world latest f2a91732366c 10 weeks ago 1.848 kB docker.io/registry 2.3.1 83139345d017 23 months ago 165.8 MB
2.3 启动docker-registry
[root@svr01 ~]# docker run -d -p 5000:5000 --restart=always -v /tmp/docker-var/:/var/lib/registry registry:2.3.1
2.4 访问搭建的镜像仓库
// 通过 curl 命令测试, 正常情况能打印些东西出来 [root@svr01 ~]# curl http://my_host_ip:5000/v2 <a href="/v2/">Moved Permanently</a>. // 通过浏览器输入 http://my_host_ip:5000/v2 地址试试,正常情况下回输出{}一个空的大括号内容。
2.5 上传测试镜像到镜像仓库中去
// 打一个tag文件 [root@svr01 ~]# docker tag busybox my_host_ip:5000/busybox [root@svr01 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE my_host_ip:5000/busybox latest 5b0d59026729 7 days ago 1.146 MB docker.io/busybox latest 5b0d59026729 7 days ago 1.146 MB docker.io/registry latest d1fd7d86a825 3 weeks ago 33.26 MB springms/gateway-zuul latest f3825f14878c 6 weeks ago 248.5 MB springms/provider-user latest 5f8a95ffddae 6 weeks ago 270.6 MB springms/discovery-eureka latest 825e3f54be46 6 weeks ago 252.5 MB springms-simple-provider-user latest 7ccdcdd5270f 6 weeks ago 235.6 MB springms-user latest 4799ed153086 6 weeks ago 235.6 MB docker.io/centos v2 11efb35f320c 6 weeks ago 307.5 MB docker.io/frolvlad/alpine-oraclejdk8 latest 4f03dc990224 8 weeks ago 170.1 MB frolvlad/alpine-oraclejdk8 slim 4f03dc990224 8 weeks ago 170.1 MB docker.io/centos latest 3fa822599e10 8 weeks ago 203.5 MB docker.io/hello-world latest f2a91732366c 10 weeks ago 1.848 kB docker.io/registry 2.3.1 83139345d017 23 months ago 165.8 MB docker.io/konradkleine/docker-registry-frontend latest 7621ed3504d4 23 months ago 234.9 MB // push文件到仓库 [root@svr01 ~]# docker push ip:5000/busybox The push refers to a repository [my_host_ip:5000/busybox] Get https://my_host_ip:5000/v1/_ping: http: server gave HTTP response to HTTPS client [root@svr01 ~]# docker push my_host_ip:5000/busybox The push refers to a repository [my_host_ip:5000/busybox] Get https://my_host_ip:5000/v1/_ping: http: server gave HTTP response to HTTPS client // 结果发现出错了, 修改 /etc/docker/daemon.json 文件,支持文件推送 文件内容为:{"insecure-registries":["my_host_ip:5000"]} // 重启docker [root@svr01 ~]# service docker restart Redirecting to /bin/systemctl restart docker.service [root@svr01 ~]# // 推送文件 [root@svr01 ~]# docker push my_host_ip:5000/busybox The push refers to a repository [my_host_ip:5000/busybox] 4febd3792a1f: Pushed latest: digest: sha256:4cee1979ba0bf7db9fc5d28fb7b798ca69ae95a47c5fecf46327720df4ff352d size: 527 [root@svr01 ~]#
2.6 查看刚刚推送的busybox文件

2.7 下载刚刚上传的镜像
// 删除已经存在的镜像 [root@svr01 ~]# docker rmi my_host_ip:5000/busybox:latest Untagged: my_host_ip:5000/busybox:latest Untagged: my_host_ip:5000/busybox@sha256:4cee1979ba0bf7db9fc5d28fb7b798ca69ae95a47c5fecf46327720df4ff352d [root@svr01 ~]# // 下载镜像 [root@svr01 ~]# docker pull my_host_ip:5000/busybox Using default tag: latest Trying to pull repository my_host_ip:5000/busybox ... latest: Pulling from my_host_ip:5000/busybox Digest: sha256:4cee1979ba0bf7db9fc5d28fb7b798ca69ae95a47c5fecf46327720df4ff352d // 查看一下,my_host_ip:5000/busybox 镜像已经下载下来了 [root@svr01 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/busybox latest 5b0d59026729 7 days ago 1.146 MB my_host_ip:5000/busybox latest 5b0d59026729 7 days ago 1.146 MB docker.io/registry latest d1fd7d86a825 3 weeks ago 33.26 MB springms/gateway-zuul latest f3825f14878c 6 weeks ago 248.5 MB springms/provider-user latest 5f8a95ffddae 6 weeks ago 270.6 MB springms/discovery-eureka latest 825e3f54be46 6 weeks ago 252.5 MB springms-simple-provider-user latest 7ccdcdd5270f 6 weeks ago 235.6 MB springms-user latest 4799ed153086 6 weeks ago 235.6 MB docker.io/centos v2 11efb35f320c 6 weeks ago 307.5 MB frolvlad/alpine-oraclejdk8 slim 4f03dc990224 8 weeks ago 170.1 MB docker.io/frolvlad/alpine-oraclejdk8 latest 4f03dc990224 8 weeks ago 170.1 MB docker.io/centos latest 3fa822599e10 8 weeks ago 203.5 MB docker.io/hello-world latest f2a91732366c 10 weeks ago 1.848 kB docker.io/registry 2.3.1 83139345d017 23 months ago 165.8 MB docker.io/konradkleine/docker-registry-frontend latest 7621ed3504d4 23 months ago 234.9 MB [root@svr01 ~]#
三、portainer管理界面安装
3.1 下载轻量级的管理界面

3.2 启动 portainer
[root@svr01 ~]# docker run -d -p 9000:9000 --restart=always -v /var/run/docker.sock:/var/run/docker.sock --name parainer-test docker.io/portainer/portainer
3.3 访问管理界面
浏览器输入 http://my_host_ip:9000/ 然后即可看到UI管理界面;
