怎么搭建Harbor私有仓库

搭建Harbor私有仓库

此时再开启一台新的虚拟机：CentOS 7-2  192.168.18.134（可以将网卡设置为静态IP）

`部署docker引擎` [root@harbor ~]# yum install yum-utils device-mapper-persistent-data lvm2 -y [root@harbor ~]# yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo [root@harbor ~]# yum install -y docker-ce [root@harbor ~]# systemctl stop firewalld.service [root@harbor ~]# setenforce 0 [root@harbor ~]# systemctl start docker.service [root@harbor ~]# systemctl enable docker.service `检查相关进程开启情况` [root@harbor ~]# ps aux | grep docker root       4913  0.8  3.6 565612 68884 ?        Ssl  12:23   0:00 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock root       5095  0.0  0.0 112676   984 pts/1    R+   12:23   0:00 grep --color=auto docker `镜像加速服务` [root@harbor ~]# tee /etc/docker/daemon.json <<-'EOF' {  "registry-mirrors": ["https://w1ogxqvl.mirror.aliyuncs.com"] } EOF [root@harbor ~]# systemctl daemon-reload [root@harbor ~]# systemctl restart docker `网络优化部分` [root@harbor ~]# echo 'net.ipv4.ip_forward=1' >> /etc/sysctl.conf [root@harbor ~]# service network restart Restarting network (via systemctl):                        [  确定  ] [root@harbor ~]# systemctl restart docker ---------- [root@harbor ~]# mkdir /aaa [root@harbor ~]# mount.cifs //192.168.0.105/rpm /aaa Password for root@//192.168.0.105/rpm: [root@harbor ~]# cd /aaa/docker/ [root@harbor docker]# cp docker-compose /usr/local/bin/ [root@harbor docker]# cd /usr/local/bin/ [root@harbor bin]# ls docker-compose [root@harbor bin]# docker-compose -v docker-compose version 1.21.1, build 5a3f1a3 [root@harbor bin]# cd /aaa/docker/ [root@harbor docker]# tar zxvf harbor-offline-installer-v1.2.2.tgz -C /usr/local/ [root@harbor docker]# cd /usr/local/harbor/ [root@harbor harbor]# ls common                     docker-compose.yml     harbor.v1.2.2.tar.gz  NOTICE docker-compose.clair.yml   harbor_1_1_0_template  install.sh            prepare docker-compose.notary.yml  harbor.cfg             LICENSE               upgrade `配置Harbor参数文件` [root@harbor harbor]# vim harbor.cfg 5 hostname = 192.168.18.134     #5行改为自己本机的IP地址 59 harbor_admin_password = Harbor12345      #此行为默认账号和密码不要忘记，登陆时要用 #修改完成后按Esc退出插入模式，输入:wq保存退出 [root@harbor harbor]# ./install.sh ......此处省略多行 Creating harbor-log ... done Creating harbor-adminserver ... done Creating harbor-db          ... done Creating registry           ... done Creating harbor-ui          ... done Creating nginx              ... done Creating harbor-jobservice  ... done ✔ ----Harbor has been installed and started successfully.---- Now you should be able to visit the admin portal at http://192.168.18.134. For more details, please visit https://github.com/vmware/harbor .

第一步：登录Harbor私有仓库

在宿主机浏览器地址栏中输入：192.168.18.134，输入默认的账户admin，密码Harbor12345，就可以点击登录

第二步：新建项目并设为私有

在项目界面点击"+项目"添加新项目，输入项目名称，点击创建，然后点击新项目左侧的三个小点，将项目设为私有

两个node节点配置连接私有仓库（注意后面的逗号要添加）

`node2节点` [root@node2 ~]# vim /etc/docker/daemon.json {  "registry-mirrors": ["https://w1ogxqvl.mirror.aliyuncs.com"],     #末尾要有,  "insecure-registries":["192.168.18.134"]                          #添加这行 } [root@node2 ~]# systemctl restart docker `node2节点` [root@node1 ~]# vim /etc/docker/daemon.json {  "registry-mirrors": ["https://w1ogxqvl.mirror.aliyuncs.com"],     #末尾要有,  "insecure-registries":["192.168.18.134"]                          #添加这行 } [root@node1 ~]# systemctl restart docker

第三步：节点上登录harbor私有仓库

`node2节点：` [root@node2 ~]# docker login 192.168.18.134 Username: admin     #输入账户admin Password:           #输入密码：Harbor12345 WARNING! Your password will be stored unencrypted in /root/.docker/config.json. Configure a credential helper to remove this warning. See https://docs.docker.com/engine/reference/commandline/login/#credentials-store Login Succeeded     #此时成功登录 `下载tomcat镜像并打标签推送：`` [root@node2 ~]# docker pull tomcat ......此处省略多行 Status: Downloaded newer image for tomcat:latest docker.io/library/tomcat:latest [root@node2 ~]# docker images REPOSITORY                                                        TAG                 IMAGE ID            CREATED             SIZE tomcat                                                            latest              aeea3708743f        3 days ago          529MB [root@node2 ~]# docker tag tomcat 192.168.18.134/project/tomcat     #打标签的过程 [root@node2 ~]# docker push 192.168.18.134/project/tomcat           #上传镜像

此时在harbor私仓界面就能看到推送上去的tomcat镜像

问题：如果我们想使用另一个节点node1去拉取私仓中的tomcar镜像就会出现error报错，提示被拒绝（也就是需要登陆）

[root@node1 ~]# docker pull 192.168.18.134/project/tomcat Using default tag: latest Error response from daemon: pull access denied for 192.168.18.134/project/tomcat, repository does not exist or may require 'docker login': denied: requested access to the resource is denied       #提示出错，缺少仓库的凭据 `node1节点下载tomcat镜像` [root@node1 ~]# docker pull tomcat:8.0.52 [root@node1 ~]# docker images REPOSITORY                                                        TAG                 IMAGE ID            CREATED             SIZE tomcat                                                            8.0.52              b4b762737ed4        19 months ago       356MB

第四步：master1上操作

[root@master1 demo]# vim tomcat01.yaml apiVersion: extensions/v1beta1 kind: Deployment metadata:  name: my-tomcat spec:  replicas: 2  template:    metadata:      labels:        app: my-tomcat    spec:      containers:      - name: my-tomcat        image: docker.io/tomcat:8.0.52        ports:        - containerPort: 80 --- apiVersion: v1 kind: Service metadata:  name: my-tomcat spec:  type: NodePort  ports:  - port: 8080    targetPort: 8080  selector:    app: my-tomcat `创建` [root@master1 demo]# kubectl create -f tomcat01.yaml deployment.extensions/my-tomcat created service/my-tomcat created `查看资源` [root@master1 demo]# kubectl get pods,deploy,svc NAME                                    READY   STATUS    RESTARTS   AGE pod/my-nginx-d55b94fd-kc2gl             1/1     Running   1          2d pod/my-nginx-d55b94fd-tkr42             1/1     Running   1          2d `pod/my-tomcat-57667b9d9-8bkns`         1/1     Running   0          84s `pod/my-tomcat-57667b9d9-kcddv`         1/1     Running   0          84s pod/mypod                               1/1     Running   1          8h pod/nginx-6c94d899fd-8pf48              1/1     Running   1          3d pod/nginx-deployment-5477945587-f5dsm   1/1     Running   1          2d23h pod/nginx-deployment-5477945587-hmgd2   1/1     Running   1          2d23h pod/nginx-deployment-5477945587-pl2hn   1/1     Running   1          2d23h NAME                                     DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE deployment.extensions/my-nginx           2         2         2            2           2d `deployment.extensions/my-tomcat`        2         2         2            2           84s deployment.extensions/nginx              1         1         1            1           8d deployment.extensions/nginx-deployment   3         3         3            3           2d23h NAME                       TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)          AGE service/kubernetes         ClusterIP   10.0.0.1     <none>        443/TCP          10d service/my-nginx-service   NodePort    10.0.0.210   <none>        80:40377/TCP     2d `service/my-tomcat          NodePort    10.0.0.86    <none>        8080:41860/TCP   84s` service/nginx-service      NodePort    10.0.0.242   <none>        80:40422/TCP     3d10h #内部端口8080，对外端口41860 [root@master1 demo]# kubectl get ep NAME               ENDPOINTS                                 AGE kubernetes         192.168.18.128:6443,192.168.18.132:6443   10d my-nginx-service   172.17.32.4:80,172.17.40.3:80             2d `my-tomcat          172.17.32.6:8080,172.17.40.6:8080         5m29s` nginx-service      172.17.40.5:80                            3d10h #此时my-tomcat被分配到了后面两个节点上去

验证：在宿主机浏览器中输入192.168.18.148:41860和192.168.18.145:41860这两个节点地址加对外暴露端口号，查看是否都可以访问tomcat的主页

`验证可以成功访问之后我们先把资源删除，后面使用私有仓库中的镜像进行创建` [root@master1 demo]# kubectl delete -f tomcat01.yaml deployment.extensions "my-tomcat" deleted service "my-tomcat" deleted

问题处理：

`如果遇到处于Terminating状态的无法删除的资源` [root@localhost demo]# kubectl get pods NAME                              READY   STATUS        RESTARTS   AGE my-tomcat-57667b9d9-8bkns         1/1     `Terminating`   0          84s my-tomcat-57667b9d9-kcddv         1/1     `Terminating`   0          84s #这种情况下可以使用强制删除命令 `格式：kubectl delete pod [pod name] --force --grace-period=0 -n [namespace]` [root@localhost demo]# kubectl delete pod my-tomcat-57667b9d9-8bkns --force --grace-period=0 -n default warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely. pod "my-tomcat-57667b9d9-8bkns" force deleted [root@localhost demo]# kubectl delete pod my-tomcat-57667b9d9-kcddv --force --grace-period=0 -n default warning: Immediate deletion does not wait for confirmation that the running resource has been terminated. The resource may continue to run on the cluster indefinitely. pod "my-tomcat-57667b9d9-kcddv" force deleted [root@localhost demo]# kubectl get pods NAME                              READY   STATUS    RESTARTS   AGE pod/mypod                               1/1     Running   1          8h pod/nginx-6c94d899fd-8pf48              1/1     Running   1          3d pod/nginx-deployment-5477945587-f5dsm   1/1     Running   1          2d23h pod/nginx-deployment-5477945587-hmgd2   1/1     Running   1          2d23h pod/nginx-deployment-5477945587-pl2hn   1/1     Running   1          2d23h

第五步：node1上操作（之前登陆过Harbor仓库的节点）

我们需要先删除我们之前上传到私有仓库的额project/tomcat镜像

node2中之前打标签的镜像也需要删除：

[root@node2 ~]# docker images REPOSITORY                                                        TAG                 IMAGE ID            CREATED             SIZE 192.168.18.134/project/tomcat                                     latest              aeea3708743f        3 days ago          529MB [root@node2 ~]# docker rmi 192.168.18.134/project/tomcat Untagged: 192.168.18.134/project/tomcat:latest Untagged: 192.168.18.134/project/tomcat@sha256:8ffa1b72bf611ac305523ed5bd6329afd051c7211fbe5f0b5c46ea5fb1adba46

`镜像打标签` [root@node2 ~]# docker tag tomcat:8.0.52 192.168.18.134/project/tomcat `上传镜像到Harbor` [root@node2 ~]# docker push 192.168.18.134/project/tomcat #此时我们就可以在私有仓库中看到新上传的镜像了 `查看登陆凭据` [root@node2 ~]# cat .docker/config.json {        "auths": {                "192.168.18.134": {     #访问的IP地址                        "auth": "YWRtaW46SGFyYm9yMTIzNDU="      #验证                }        },        "HttpHeaders": {                #头部信息                "User-Agent": "Docker-Client/19.03.5 (linux)"        } `生成非换行形式的验证码` [root@node2 ~]# cat .docker/config.json | base64 -w 0 ewoJImF1dGhzIjogewoJCSIxOTIuMTY4LjE4LjEzNCI6IHsKCQkJImF1dGgiOiAiWVdSdGFXNDZTR0Z5WW05eU1USXpORFU9IgoJCX0KCX0sCgkiSHR0cEhlYWRlcnMiOiB7CgkJIlVzZXItQWdlbnQiOiAiRG9ja2VyLUNsaWVudC8xOS4wMy41IChsaW51eCkiCgl9Cn0=   

特别注意：此时下载次数为0，一会我们使用私有仓库中的镜像进行资源的创建，那么拉取的过程必定会下载镜像，应当数值会有变化

第六步：master1中创建安全组件的yaml文件

[root@master1 demo]# vim registry-pull-secret.yaml apiVersion: v1 kind: Secret metadata:  name: registry-pull-secret data:  .dockerconfigjson: ewoJImF1dGhzIjogewoJCSIxOTIuMTY4LjE4LjEzNCI6IHsKCQkJImF1dGgiOiAiWVdSdGFXNDZTR0Z5WW05eU1USXpORFU9IgoJCX0KCX0sCgkiSHR0cEhlYWRlcnMiOiB7CgkJIlVzZXItQWdlbnQiOiAiRG9ja2VyLUNsaWVudC8xOS4wMy41IChsaW51eCkiCgl9Cn0= type: kubernetes.io/dockerconfigjson `创建secret资源` [root@master1 demo]# kubectl create -f registry-pull-secret.yaml secret/registry-pull-secret created `查看secret资源` [root@master1 demo]# kubectl get secret NAME                   TYPE                                  DATA   AGE default-token-pbr9p    kubernetes.io/service-account-token   3      10d `registry-pull-secret   kubernetes.io/dockerconfigjson        1      25s` [root@master1 demo]# vim tomcat01.yaml apiVersion: extensions/v1beta1 kind: Deployment metadata:  name: my-tomcat spec:  replicas: 2  template:    metadata:      labels:        app: my-tomcat    spec:      imagePullSecrets:             #证书拉取的凭据      - name: registry-pull-secret  #名称      containers:      - name: my-tomcat        image: 192.168.18.134/project/tomcat    #镜像的下载位置做此修改        ports:        - containerPort: 80 ......以下省略多行 #修改完成后按Esc退出插入模式，输入:wq保存退出 `创建tomcat01资源` [root@master1 demo]# kubectl create -f tomcat01.yaml deployment.extensions/my-tomcat created service/my-tomcat created [root@master1 demo]# kubectl get pods,deploy,svc,ep NAME                                    READY   STATUS    RESTARTS   AGE pod/my-nginx-d55b94fd-kc2gl             1/1     Running   1          2d1h pod/my-nginx-d55b94fd-tkr42             1/1     Running   1          2d1h `pod/my-tomcat-7c5b6db486-bzjlv`        1/1     Running   0          56s `pod/my-tomcat-7c5b6db486-kw8m4`        1/1     Running   0          56s pod/mypod                               1/1     Running   1          9h pod/nginx-6c94d899fd-8pf48              1/1     Running   1          3d1h pod/nginx-deployment-5477945587-f5dsm   1/1     Running   1          3d pod/nginx-deployment-5477945587-hmgd2   1/1     Running   1          3d pod/nginx-deployment-5477945587-pl2hn   1/1     Running   1          3d NAME                                     DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE deployment.extensions/my-nginx           2         2         2            2          2d1h `deployment.extensions/my-tomcat`        2         2         2            2           56s deployment.extensions/nginx              1         1         1            1           8d deployment.extensions/nginx-deployment   3         3         3            3           3d NAME                       TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)          AGE service/kubernetes         ClusterIP   10.0.0.1     <none>        443/TCP          10d service/my-nginx-service   NodePort    10.0.0.210   <none>        80:40377/TCP     2d1h `service/my-tomcat`        NodePort    10.0.0.235   <none>        8080:43654/TCP   56s service/nginx-service      NodePort    10.0.0.242   <none>        80:40422/TCP     3d11h #对外端口为43654 NAME                         ENDPOINTS                                 AGE endpoints/kubernetes         192.168.18.128:6443,192.168.18.132:6443   10d endpoints/my-nginx-service   172.17.32.4:80,172.17.40.3:80             2d1h `endpoints/my-tomcat`        172.17.32.6:8080,172.17.40.6:8080         56s endpoints/nginx-service      172.17.40.5:80                            3d11h

接下来我们需要验证的就是资源加载没有任何问题的情况下，镜像资源是否来自我们的Harbor私有仓库呢？

这里就需要关注我们私有仓库中镜像的下载数了

结果：这时显示下载数由之前的0变为2，这就说明我们创建的两个资源镜像是从私有仓库中下载的！

我们再使用宿主机的浏览器验证192.168.18.148:43654和192.168.18.145:43654这两个节点地址还是可以访问tomcat的主页
