怎么搭建Harbor私有仓库

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.

`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

[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

怎么搭建Harbor私有仓库

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

第四步：master1上操作
[root@master1 demo]# vim tomcat01.yaml
apiVersion: extensions/v1beta1

  replicas: 2
  template:

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

怎么搭建Harbor私有仓库

`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

怎么搭建Harbor私有仓库

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

        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`

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

怎么搭建Harbor私有仓库

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
