《kubernetes 1.8.0 测试环境安装部署》

时间：2017-11-27

一、环境准备

docker版本：1.17
docker-compose版本：1.17

安装docker-compose

curl -L https://github.com/docker/compose/releases/download/1.17.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

从harbor 发布页面下载最新的harbor offline安装包（当前版本v1.3.0-rc1）：

wget  --continue http://harbor.orientsoft.cn/harbor-v1.3.0-rc1/harbor-offline-installer-v1.3.0-rc1.tgz

1.3.0开始建议去镜像站下载，嗷嗷快

解压tarball,并加载镜像：

$ tar -zxvf harbor-offline-installer-v1.3.0-rc1.tgz 
$ cd harbor
$ docker load -i harbor.v1.3.0-rc1.tar.gz

创建harbor所需证书：

签名请求：

$ cat > harbor-csr.json <<EOF
{"CN": "harbor","hosts": ["127.0.0.1","172.18.169.134"],"key": {"algo": "rsa","size": 2048},"names": [{"C": "CN","ST": "BeiJing","L": "BeiJing","O": "k8s","OU": "System"}]
}
EOF

• "hosts"：本例中改字段使用ip，实际测试环境中使用的是域名，方便外网使用。

创建证书和秘钥：

由于是在node节点上部署，使用k8s根ca做签名，因此沿用原有k8s ca根证书，重新创建或者从master节点上拷贝k8s-gencert.json（配置文件） 以及ca证书和key（签完后删除）

 scp /etc/kubernetes/ssl/k8s-root-ca-key.pem root@172.18.169.134:/etc/kubernetes/ssl/

cat > /etc/kubernetes/ssl/k8s-gencert.json  << EOF
{"signing": {"default": {"expiry": "87600h"},"profiles": {"kubernetes": {"usages": ["signing","key encipherment","server auth","client auth"],"expiry": "87600h"}}}
}
EOF

创建证书秘钥：

$ cfssl gencert -ca=/etc/kubernetes/ssl/k8s-root-ca.pem \-ca-key=/etc/kubernetes/ssl/k8s-root-ca-key.pem \-config=/etc/kubernetes/ssl/k8s-gencert.json \-profile=kubernetes harbor-csr.json | cfssljson -bare harbor
$ ls harbor*
harbor.csr  harbor-csr.json  harbor-key.pem harbor.pem
$ sudo mkdir -p /etc/harbor/ssl
$ sudo mv harbor*.pem /etc/harbor/ssl
$ rm /etc/kubernetes/ssl/k8s-root-ca-key.pem 
$ rm harbor.csr  harbor-csr.json

二、部署harbor

修改harbor.cfg 文件

$ vi harbor.cfg修改一下参数hostname = 172.18.169.134 
ui_url_protocol = https 
ssl_cert = /etc/harbor/ssl/harbor.pem
ssl_cert_key = /etc/harbor/ssl/harbor-key.pem

加载和启动 harbor 镜像

[root@node-134 harbor]# vi harbor.cfg 
## Configuration file of Harbor#The IP address or hostname to access admin UI and registry service.
#DO NOT use localhost or 127.0.0.1, because Harbor needs to be accessed by external clients.
hostname = 172.18.169.134#The protocol for accessing the UI and token/notification service, by default it is http.
#It can be set to https if ssl is enabled on nginx.
ui_url_protocol = https#The password for the root user of mysql db, change this before any production use.
db_password = root123#Maximum number of job workers in job service
max_job_workers = 3#Determine whether or not to generate certificate for the registry's token.
#If the value is on, the prepare script creates new root cert and private key
#for generating token to access the registry. If the value is off the default key/cert will be used.
#This flag also controls the creation of the notary signer's cert.
customize_crt = on#The path of cert and key files for nginx, they are applied only the protocol is set to https
ssl_cert = /etc/harbor/ssl/harbor.pem
ssl_cert_key = /etc/harbor/ssl/harbor-key.pem#The path of secretkey storage
secretkey_path = /data#Admiral's url, comment this attribute, or set its value to NA when Harbor is standalone
admiral_url = NA#The password of the Clair's postgres database, only effective when Harbor is deployed with Clair.
#Please update it before deployment, subsequent update will cause Clair's API server and Harbor unable to access Clair's database.
clair_db_password = password"harbor.cfg" 125L, 5021C written

三、测试访问

浏览器访问 https://${NODE_IP}，示例的是 https://172.18.169.134

用账号 admin 和 harbor.cfg 配置文件中的默认密码 Harbor12345 登陆系统：

harbor 运行时产生的文件、目录：

$ # 日志目录
$ ls /var/log/harbor/
adminserver.log  jobservice.log  mysql.log  proxy.log  registry.log  ui.log
$ # 数据目录，包括数据库、镜像仓库
$ ls /data/
ca_download  config  database  job_logs registry  secretkey

docker 客户端访问：

将签署 harbor 证书的 CA 证书拷贝到 /etc/docker/certs.d/172.18.169.134 目录下

$ sudo mkdir -p /etc/docker/certs.d/172.18.169.134
$ sudo cp /etc/kubernetes/ssl/k8s-root-ca.pem /etc/docker/certs.d/172.18.169.134/ca.crt

测试登陆：

[root@node-134 harbor]# docker login 172.18.169.134
Username: admin
Password: 
Login Succeeded

认证信息自动保存到 ~/.docker/config.json 文件。

测试上传镜像：

web界面创建项目-elk：

查看ELK相关镜像：

[root@node-131 ~]# docker images

...

给这些镜像贴上tag（格式：仓库地址/项目/镜像名:版本）：

docker tag gcr.io/google-containers/elasticsearch:v5.6.4 \
172.18.169.134/elk/elasticsearch:v5.6.4

查看一下：

[root@node-131 ~]# docker images
REPOSITORY                                                       TAG                 IMAGE ID            CREATED             SIZE
...

...

上传镜像：
