构建企业级镜像仓库

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. 启动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. 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
REPOSITORY           TAG             IMAGE ID            CREATED             SIZE
