Docker安装Harbor镜像仓库+HTTPS配置+API2.0操作

导读:本篇文章讲解 Docker安装Harbor镜像仓库+HTTPS配置+API2.0操作,希望对大家有帮助,欢迎收藏,转发!站点地址:www.bmabk.com

1. 准备事项

安装准备,详见官网:Harbor Installation Prerequisites

  • 检测80端口是否被占用:netstat -tunlp|grep 80,若使用其它端口,需在2.2节配置的hostname中加上端口号
  • harbor可能与ceph存在冲突,尽量选择其它节点部署
  • 环境:docker、docker-compose、https

image-20210324163804178

1.1. 安装docker

  • 移除电脑上原有的dockers
yum remove docker \
           docker-client \
           docker-client-latest \
           docker-common \
           docker-latest \
           docker-latest-logrotate \
           docker-logrotate \
           docker-engine
  • 安装docker
yum install -y yum-utils
 
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
 
yum install -y docker-ce
  • 配置阿里云镜像加速器

    加速器地址:阿里云控制台–容器镜像服务–镜像工具–镜像加速器

mkdir -p /etc/docker
 
tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://xxxxx.mirror.aliyuncs.com"]
}
EOF
  • 验证
systemctl daemon-reload &&
systemctl restart docker &&
systemctl enable docker &&
systemctl status docker

1.2. 安装docker-compose

- 授权
chmod +x

- 移动并改名(去掉版本号)
mv [] /usr/local/bin/docker-compose

- 验证
docker-compose version

1.3. 配置HTTPS访问证书

  • 在工作目录下创建证书存放目录
mkdir ssl 
cd ssl 
  • 创建证书
openssl req  -newkey rsa:4096 -nodes -sha256 -keyout ca.key -x509 -days 3650 -out ca.crt

# 一路回车5次直至出现Common Name 输入(因为是CA,可不输入IP或域名):Harbor Cert Root CA  
注:Harbor为自定义名称

image-20210620141557774

  • 生成证书签名请求
openssl req  -newkey rsa:4096 -nodes -sha256 -keyout harbor.key -out harbor.csr

# 一路回车5次出现Common Name 输入IP或域名:lc.harbor.cn

image-20210620141648882

  • 新建extfile.cnf
--- vim extfile.cnf  --- 

subjectAltName = @alt_names
extendedKeyUsage = serverAuth

[alt_names]
# 域名,如有多个用DNS.2,DNS.3…来增加
DNS.1 = lc.harbor.cn
DNS.2 = *.harbor.cn
# IP地址, 服务器的ip
IP.1 = 172.16.16.104
IP.2 = 127.0.0.1
  • 生成证书
openssl x509 -req -days 3650 -in harbor.csr -CA ca.crt -CAkey ca.key -CAcreateserial -extfile extfile.cnf -out harbor.crt

image-20210620141826278

1.4. 为docker login配置证书

  • 方式一:配置docker的CA证书,不需要重启docker(墙裂建议)
- 创建目录
mkdir -p /etc/docker/certs.d/lc.harbor.cn/
- 分发证书
cp ca.crt /etc/docker/certs.d/lc.harbor.cn/
  • 方式二:配置insecure-registries,跳过https认证,重启docker生效
vim /etc/docker/daemon.json

"insecure-registries": ["xxx","lc.harbor.cn"],

-----------
- 重启docker
systemctl restart docker

image-20210620141940796

  • 方式三:配置系统级CA认证,需重启docker
- 分发证书
scp ca.crt root@172.16.16.103:/etc/pki/ca-trust/source/anchors/

- 更新配置并重启docker
update-ca-trust extract &&
systemctl restart docker

1.5. 附:Ansible一键配置集群证书

  • hosts
[master]
172.16.16.11 node_name=k8s-master1
172.16.16.12 node_name=k8s-master2
172.16.16.13 node_name=k8s-master3

[node]
172.16.16.101 node_name=k8s-node1
172.16.16.102 node_name=k8s-node2
172.16.16.103 node_name=k8s-node3
172.16.16.104 node_name=k8s-node4
  • scp-harbor-cert.yml(将ca证书放在同目录下)
- hosts:
  - master
  - node
  tasks:
  - name: 删除相关的host解析
    shell: sed -i '/lc.harbor.cn/d' /etc/hosts
  - name: 添加hosts
    lineinfile: dest=/etc/hosts line="172.16.16.104 lc.harbor.cn"
  - name: 创建证书目录
    file: dest=/etc/docker/certs.d/lc.harbor.cn/ state=directory
  - name: 分发证书
    copy: src=./ca.crt dest=/etc/docker/certs.d/lc.harbor.cn/
  • 执行
ansible-playbook -i hosts scp-harbor-cert.yml -uroot -k

2. docker-compose安装Harbor

2.1. 下载harbor安装包

tar zxvf harbor-offline-installer-v2.2.2.tgz

image-20210620142144226

2.2. 配置harbor

  • hostname:本机IP
  • 证书地址:见1.3节
  • 仓库地址:自定义
- 编辑harbor.yml.tmpl(按需修改)

vim harbor.yml.tmpl
------------------------

hostname: 172.16.16.104

http:
  port: 80
https:
  port: 443
  certificate: /root/harbor/ssl/harbor.crt
  private_key: /root/harbo/ssl/harbor.key

harbor_admin_password: Harbor12345

------------------------

- 生成harbor.yml文件
cp harbor.yml.tmpl harbor.yml

image-20210620143010495

  • 解压镜像
docker load --input harbor.v2.2.2.tar.gz

image-20210620142508960

  • 执行
./prepare
./install.sh

image-20210620143353484

2.3. 设置开机启动

  • 虽然docker-compose.yml中所有服务restart策略为always,但是docker或服务器重启后并不是所有服务都会自动重启

image-20210621142625055

  • 配置开机启动

参考官方Issue

vim /usr/lib/systemd/system/harbor.service
------------------------------------------------

[Unit]
Description=Harbor
After=docker.service systemd-networkd.service systemd-resolved.service
Requires=docker.service
Documentation=http://github.com/vmware/harbor

[Service]
Type=simple
Restart=on-failure
RestartSec=5
#注意docker-compose和harbor的安装位置
ExecStart=/usr/local/bin/docker-compose -f  /root/harbor/harbor/docker-compose.yml up
ExecStop=/usr/local/bin/docker-compose -f /root/harbor/harbor/docker-compose.yml down

[Install]
WantedBy=multi-user.target
  • 启动harbor服务
systemctl enable harbor
systemctl restart harbor
  • 查看harbor服务状态
systemctl status harbor

3. 登录harbor仓库

3.1. 网页登录

  • 配置hosts
win10 hosts路径:C:\Windows\System32\drivers\etc\hosts
------------------

121.89.211.133 lc.harbor.cn 

image-20210620143924267

3.2. docker登录

  • 配置hosts
- vim /etc/hosts(公网/私网按需配置)
------------------------

172.16.16.104 lc.harbor.cn 
  • docker login
docker login lc.harbor.cn -uadmin

image-20210620144412989

3.3. 推送镜像

- 拉取官方镜像(默认tag为latest)
docker pull nginx

- 查看镜像
docker images |grep nginx

- 打tag
docker tag nginx:latest lc.harbor.cn/library/nginx:latest

- 推送(默认推送镜像需要登录)
docker push lc.harbor.cn/library/nginx:latest

image-20210620144722610

  • 网页上查看镜像

image-20210620144905455

3.4. 拉取镜像

  • 先移除本地打了tag的镜像
docker rmi lc.harbor.cn/library/nginx:latest
  • 拉取镜像
docker pull lc.harbor.cn/library/nginx:latest

image-20210620145218819

4. Harbor后台API2.0

4.1. 准备事项

  • API手册链接位于网页左下角
  • 标记多个tag并推送(不能使用相同的镜像)
docker tag nginx:1.17.0 lc.harbor.cn/library/nginx:100
docker tag nginx:1.18.0 lc.harbor.cn/library/nginx:18
docker tag nginx:1.19.0 lc.harbor.cn/library/nginx:19
docker tag nginx:1.20.0 lc.harbor.cn/library/nginx:20
docker tag nginx:latest lc.harbor.cn/library/nginx:latest

推送顺序:latest,100,18,19,20

4.2. HarborAPI2.0删除镜像示例

  1. 获取项目/仓库下的镜像信息
image_info=$(curl -s -k -u admin:Harbor12345 -X GET "https://lc.harbor.cn/api/v2.0/projects/library/repositories/nginx/artifacts?page=1&page_size=10&with_tag=true&with_label=false&with_scan_overview=false&with_signature=false&with_immutable_status=false" -H "accept: application/json")

echo $image_info
  1. 提取出镜像tag
tags="$(echo "$image_info" | tr , '\n' | grep name | cut -d '"' -f4)"

echo $tags

image-20210620153727861

  1. 镜像tag排序,取出最近3个镜像以外的tag
for tag in `echo ${tags} | awk 'BEGIN{i=1}{gsub(/ /,"\n");i++;print}' | awk -F. '{print $NF}' | sed "1,3d"`;
do
curl -s -k -u admin:Harbor12345 -X DELETE https://lc.harbor.cn/api/v2.0/projects/library/repositories/nginx/artifacts/${tag}
done
