docker 、rancher搭建
一、安裝前準備:
配置本地yum源
1).mount -t iso9660 -o loop /dev/cdrom /media/centos
2).vi /etc/yum.repo.d/Centos_localsource.repo
[CentOS7-Localsource] name=CentOS7 baseurl=file:///media/centos enabled=1 gpgcheck=0
2.配置網絡yum源
下載163網易的yum源: wget http://mirrors.163.com/.help/CentOS7-Base-163.repo 中科大的yum源: wget http://centos.ustc.edu.cn/CentOS-Base.repo sohu的yum源 wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo
3.yum clean all
yum makecache
yum isntall vim net-tools #(支持ifconfig)
(setenforce 0 && systemctl stop firewalld)
二、安裝docker和rancher
下載docker的rpm包(https://download.docker.com/linux/centos/7/x86_64/stable/Packages/)
docker-ce-17.06.0.ce-1.el7.centos.x86_64.rpm
安裝docker
yum install docker-ce-17.06.0.ce-1.el7.centos.x86_64.rpm
配置docker加速器
vi /etc/docker/daemon.json
{"registry-mirrors": [" 或 {"registry-mirrors": ["https://registry.docker-cn.com"]}
4.systemctl start docker
5.docker pull rancher/server
6.啟動rancher server
docker run -d -v /data1/mysql:/var/lib/mysql --name=rancher-server --restart=unless-stopped -p 7070:8080 rancher/server
7.rancher頁面配置及rancher-agent安裝見http://blog.chinaunix.net/uid-29757900-id-5676591.html
三、安裝registry
docker pull registry
運行registry容器
docker run -d --restart=always -p 5000:5000 --name repo -v /var/lib/registry:/var/lib/registry registry
3.修改/etc/docker/daemon.json添加"insecure-registries":["registry:5000"](參考:http://www.cnblogs.com/lin1/p/6207348.html)
{"registry-mirrors": ["https://registry.docker-cn.com"],"insecure-registries":["192.168.206.134:5000"] }
4.重啟docker
systemctl restart docker
5.將公有倉庫下載docker包上傳到私有倉庫(http://www.cnblogs.com/fengzheng/p/5168951.html)
#下載mysql鏡像 docker pull mysql #重新標記一個本地鏡像為私有倉庫的版本,這裏將本地的mysql latest標記為192.168.206.134:5000/mysql:yang docker tag mysql:latest 192.168.206.134:5000/mysql:yang #將本地鏡像推送到本地倉庫中 docker push 192.168.206.134:5000/mysql:yang #查看本地倉庫中的鏡像列表 [[email protected] yum.repos.d]# curl http://localhost:5000/v2/mysql/tags/list {"name":"mysql","tags":["yang"]} #拉取本地倉庫中的鏡像 docker pull localhost:5000/mysql:yang
6.私有倉庫 Registry中的鏡像管理
#檢查registry上的鏡像 for i in `curl -s 127.0.0.1:5000/v2/_catalog | sed‘s/repositories// ; s/[\[\"\:\{\}]*//g ; s/,/ /g ; s/]//g‘` ; do curl -s 127.0.0.1:5000/v2/$i/tags/list|sed‘s/[\{\}\"]//g; s/name://g; s/,tags:/\t/g‘ ; done #刪除私有 registry 中的鏡像(參考:http://www.cnblogs.com/wjoyxt/p/5855405.html) 1.修改配置/etc/docker/registry/config.yml 2.使用 API GET /v2/<鏡像名>/manifests/<tag> 來取得要刪除的鏡像:Tag所對應的 digest 比如,要刪除 mysql:yang 鏡像,那麽取得 digest 的命令是: curl --header "Accept: application/vnd.docker.distribution.manifest.v2+json" -I -X HEAD http://192.168.206.134:5000/v2/mysql/manifests/yang 3.然後調用 API DELETE /v2/<鏡像名>/manifests/<digest> 來刪除鏡像。比如: [[email protected] yum.repos.d]# curl -X DELETE "http://192.168.206.134:5000/v2/mysql/manifests/sha256:afd334d5f3b4c31155a09110ad7f4728e8b5c8bdf8bca711aed61cf8247dfdec" {"errors":[{"code":"UNSUPPORTED","message":"The operation is unsupported."}]} ----配置文件已改,但是沒刪除成功。問題待解----
