安装harbor有两种模式：
harbor-online-installer-0.5.0.tgz: for
host that can connect directly to Internet.
harbor-offline-installer-0.5.0.tgz:
for host that does not have connectivity to Internet.
本文选用offline安装。
l安装前准备工作：
1.Python should be version 2.7 orhigher. Note that you may have to install Python on Linux distributions(Gentoo, Arch) that do not come with a Python interpreter installed by default
2.Docker engine should be version1.10 or higher. For installation instructions, please refer to:https://docs.docker.com/engine/installation/
3.Docker Compose needs to beversion 1.6.0 or higher. For installation instructions, please refer to:https://docs.docker.com/compose/install/
l安装harbor步骤：
1、下载最新安装包
wgethttps://github.com/vmware/harbor/releases/download/0.5.0/harbor-offline-installer-0.5.0.tgz
解压安装包：
$ tar xvf
harbor-offline-installer-.tgz
2、配置harbor
需要仔细查看配置，配成自己需要的模式。可参考如下配置：
3、进入harbor文件目录，执行./install.sh
4、打开http://10.142.21.113网址即可登录harbor界面
l配置harbor作为k8s私有镜像仓库
1.在harbor上创建用户，项目，将用户添加到对应项目中，并赋予用户项目管理者或者开发人员权限，使其对镜像仓库有读写权限。
本次部署创建用户cm-test，密码Dcos1234，邮箱[email protected]，项目library
2.创建secret
使用命令行：
kubectl create secret docker-registryharbortest--namespace=kube-system\
--docker-server=10.142.21.113--docker-username=cm-test\
--docker-password=Dcos1234--docker-email=chenmiao@cmss.chinamobile.com
注意：
此处关键信息为标红，用户信息为对应haobor中创建的用户信息。
3.查看secret内容
kubectl get secret harbortest--namespace=kube-system -o yaml
输出：
apiVersion: v1
data:
.dockercfg: eyIxMC4xNDIuMjEuMTEzIjp7InVzZXJuYW1lIjoiY20tdGVzdCIsInBhc3N3b3JkIjoiRGNvczEyMzQiLCJlbWFpbCI6ImNoZW5taWFvQGNtc3MuY2hpbmFtb2JpbGUuY29tIiwiYXV0aCI6IlkyMHRkR1Z6ZERwRVkyOXpNVEl6TkE9PSJ9fQ==
kind: Secret
metadata:
creationTimestamp: 2017-02-07T03:30:59Z
name: harbortest
namespace: kube-system
resourceVersion: "682020"
selfLink: /api/v1/namespaces/kube-system/secrets/harbortest
uid: d82774f6-ece5-11e6-b231-005056943bc9
type: kubernetes.io/dockercfg
4.关联serviceAccount
4.1使用kubectl get
serviceaccounts defult –o yaml查看默认serviceaccount信息。
4.2kubectl get serviceaccounts defult –o yaml > service.yaml
4.3 vim service.yaml修改如下信息，主要将imagePullSecrets:字段加入配置文件，使得前面创建的secret生效，从而能从harbor上面对应权限用户的项目中pull镜像创建pod
修改为如下：
apiVersion: v1
kind: ServiceAccount
metadata:
creationTimestamp: 2017-01-18T05:02:19Z
name: default
namespace: default
selfLink: /api/v1/namespaces/default/serviceaccounts/default
uid: 49eb802c-dd3b-11e6-b735-005056943bc9
secrets:
- name: default-token-wl2bb
imagePullSecrets:
- name: harbortest
注意：要去掉resourcesVersion：那一行
4.4kubectl replace serviceaccount default -f ./sa.yaml
新的serviceaccount创建成功
l是否可用，部署一个k8s-dashboard的pod
在pod的yaml文件中增加如下字段即可完成harbor作为k8s私有镜像仓库。
spec:
imagePullSecrets:
- name:harbortest
containers:
- name: kubernetes-dashboard
image:
10.142.21.113/library/kubernetes-dashboard-amd64
详细yaml文件如下：
kind:Deployment
apiVersion:extensions/v1beta1

app: kubernetes-dashboard

l部署过程中可能遇到的问题：
私有镜像仓库信任问题：
vi /usr/lib/systemd/system/docker.service
以上是直接修改每个节点上deamon启动配置
docker -d --insecure-registry 10.142.21.113-H fd:// $OPTIONS $DOCKER_STORAGE_OPTIONS
LimitNOFILE=1048576
LimitNPROC=1048576
