构建企业级镜像仓库
Harbor是由VMware公司开源的镜像仓库,harbor是在docker Registry上进行了企业级扩展,从而获得了更广泛的应用,这些新的企业级特性包括:管理用户界面,基于角色的访问控制,AD/LDAP继承以及审计日志的功能,足以满足企业需求.
官方地址: https://vmware.github.io/barbor/cn/
安装harbor
wget https://www.chenleilei.net/soft/k8s/harbor-offline-installer-v1.9.3.tgz
tar xf harbor-offline-installer-v1.9.3.tgz
cd harbor
vi harbor.yml
修改hostname为本机IP地址
#hostname: reg.mydomain.com
hostname: 10.0.0.64
修改完毕后保存.
准备harbor仓库:
[root@master1 harbor]# ./prepare
#注意安装harbor需要依赖两个环境 一个是docker 一个是docker compose
docker已经安装完毕.现在安装docker compose
同时你直接安装也会提醒你 没有安装docke-compose:
Note: docker version: 19.03.7
✖ Need to install docker-compose(1.18.0+) by yourself first and run this script again
1. 安装docker compose:
git clone https://github.com/docker/compose.git 或者上传 compose
https://www.chenleilei.net/soft/docker/docker-compose-Linux-x86_64.tar.gz
课件:第一阶段重新认识Docker课件.zip中也有,上传docker-compose
[root@master1 harbor]# tar xf docker-compose-Linux-x86_64.tar.gz
[root@master1 harbor]# mv docker-compose-Linux-x86_64 /usr/bin/docker-compose
[root@master1 harbor]# chmod +x /usr/bin/docker-compose
2. 安装harbor
wget https://www.chenleilei.net/soft/k8s/harbor-offline-installer-v1.9.3.tgz
tar xf harbor-offline-installer-v1.9.3.tgz
[root@master1 ~]# tar -xf harbor-offline-installer-v1.9.3.tgz -C /usr/local/
[root@master1 ~]# mv /usr/local/
[root@master1 ~]# cd /usr/local/harbor
[root@master1 ~]# vi harbor.yml
修改hostname为本机IP地址
#hostname: reg.mydomain.com 这行注释,下面写:
hostname: 10.0.0.64
修改完毕后保存.
3. 初始化harbor:
[root@master1 harbor]# ./prepare
[root@master1 harbor]# ./install.sh #安装,之后如果要启动则使用: /harbor/start.sh 即可
4. 启动harbor:
[root@master1 harbor]# docker-compose start
Starting log ... done
Starting registry ... done
Starting registryctl ... done
Starting postgresql ... done
Starting portal ... done
Starting redis ... done
Starting core ... done
Starting jobservice ... done
Starting proxy ... done
启动成功后查看状态:
[root@master1 harbor]# docker-compose ps
Name Command State Ports
---------------------------------------------------------------------------------------------
harbor-core /harbor/harbor_core Up (healthy)
harbor-db /docker-entrypoint.sh Up (healthy) 5432/tcp
harbor-jobservice /harbor/harbor_jobservice ... Up (healthy)
harbor-log /bin/sh -c /usr/local/bin/ ... Up (healthy) 127.0.0.1:1514->10514/tcp
harbor-portal nginx -g daemon off; Up (healthy) 8080/tcp
nginx nginx -g daemon off; Up (healthy) 0.0.0.0:80->8080/tcp
redis redis-server /etc/redis.conf Up (healthy) 6379/tcp
registry /entrypoint.sh /etc/regist ... Up (healthy) 5000/tcp
registryctl /harbor/start.sh Up (healthy)
如果你看到的状态事这样:
Can't find a suitable configuration file in this directory or any
parent. Are you in the right directory?
Supported filenames: docker-compose.yml, docker-compose.yaml
那么可能是 你不在harbor目录中或者命令没有配置..需要先进入harbor目录再次查看.
4. 检擦harbor启动状态:
[root@k8s-master2 harbor]# ps -ef|grep harbor
root 101657 101620 0 16:18 ? 00:00:00 /bin/sh /harbor/start.sh
root 101934 101657 0 16:18 ? 00:00:00 sudo -E -u #10000 /harbor/harbor_registryctl -c /etc/registryctl/config.yml
10000 101939 101934 0 16:18 ? 00:00:00 /harbor/harbor_registryctl -c /etc/registryctl/config.yml
10000 101970 101952 0 16:18 ? 00:00:00 /harbor/harbor_core
10000 102052 102035 0 16:18 ? 00:00:00 /harbor/harbor_jobservice -c /etc/jobservice/config.yml
root 102587 45443 0 16:19 pts/1 00:00:00 grep --color=auto harbor
5. 登录harbor
默认账号密码:
admin
Harbor12345
harbor的日常使用
harbor需要创建用户,分配给运维或开发人员使用.
如何推送镜像到harbor中?
本地先dockerfile制作个镜像:
FROM centos:7
LABEL maintainer www.chenleilei.net
RUN useradd www -u 1200 -M -s /sbin/nologin
RUN mkdir -p /var/log/nginx
RUN yum install -y cmake pcre pcre-devel openssl openssl-devel gd-devel \
zlib-devel gcc gcc-c++ net-tools iproute telnet wget curl &&\
yum clean all && \
rm -rf /var/cache/yum/*
RUN wget https://www.chenleilei.net/soft/nginx-1.16.1.tar.gz
RUN tar xf nginx-1.16.1.tar.gz
WORKDIR nginx-1.16.1
RUN ./configure --prefix=/usr/local/nginx --with-http_image_filter_module --user=www --group=www \
--with-http_ssl_module --with-http_v2_module --with-http_stub_status_module \
--error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log \
--pid-path=/var/run/nginx/nginx.pid
RUN make -j 4 && make install && \
rm -rf /usr/local/nginx/html/* && \
echo "leilei hello" >/usr/local/nginx/html/index.html && \
rm -rf nginx* && \
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime &&\
ln -sf /dev/stdout /var/log/nginx/access.log && \
ln -sf /dev/stderr /var/log/nginx/error.log
RUN chown -R www.www /var/log/nginx
ENV LOG_DIR /var/log/nginx
ENV PATH $PATH:/usr/local/nginx/sbin
#COPY nginx.conf /usr/local/nginx/conf/nginx.conf
EXPOSE 80
WORKDIR /usr/local/nginx
CMD ["nginx","-g","daemon off;"]
#运行镜像:
docker run --name ngix-test-001 -d -p 81:80 nginx-test-v001

推送镜像到harbor
推送镜像:
1. 给镜像打 tag 标签
docker tag nginx:v1 192.168.31
harbor推送失败:
[root@k8s-master2 ~]# docker push 10.0.0.64/library/nginx-test-v001:v1
The push refers to repository [10.0.0.64/library/nginx-test-v001]
Get https://10.0.0.64/v2/: dial tcp 10.0.0.64:443: connect: connection refused
原因: harbor默认是https访问的,需要添加可信任,而我们通过 docker info查看到的信任IP段只有本地127.0.0.0网段
Insecure Registries:
127.0.0.0/8
为此,我们需要添加可信任的IP网段才行,那么如何添加呢?
解决harbor推送失败:
1. 修改 /etc/docker/daemon.json
添加如下行:
"Insecure-registries" :["10.0.0.64"]
这里的IP是harbor仓库地址.
修改结果:
[root@k8s-master2 ~]# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://ajvcw8qn.mirror.aliyuncs.com"],
"insecure-registries": ["10.0.0.64"]
}
2. 重启docker
systemctl restart docker
3. 重启docker-compose
[root@k8s-master2 ~]# cd /usr/local/harbor
[root@k8s-master2 harbor]# docker-compose up -d
harbor-log is up-to-date
Starting redis ... done
Starting registryctl ... done
Starting harbor-portal ... done
Starting harbor-db ... done
Starting registry ... done
Starting harbor-core ... done
Starting nginx ... done
Starting harbor-jobservice ... done
4. 访问测试:
[root@k8s-master2 harbor]# docker push 10.0.0.64/library/nginx-test-v001:v1
The push refers to repository [10.0.0.64/library/nginx-test-v001]

检查镜像:
推送镜像步骤整理:
1. 添加harbor信任
1. 给镜像打tag标签 docker tag nginx:v1 10.0.0.64/library/nginx-test-v001:v1
2. 登录到仓库 docker login 10.0.0.64 默认账号 admin 默认密码 Harbor12345
3. 推送到指定仓库. docker push 10.0.0.64/library/nginx-test-v001:v1
1. 添加harbor信任:
[root@k8s-master2 ~]# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://ajvcw8qn.mirror.aliyuncs.com"],
"insecure-registries": ["10.0.0.64"]
}
2. 重启docker
systemctl restart docker.service
3. 查看已有镜像:
[root@master1 ~]# docker images
