Docker Harbor 私仓实践
背景
由于期望搭建一个企业级CICD的环境，开始尝试常规的gitlab+jenkins+k8s+docker harbor+springboot开始练手
其中版本如下：
1.gitlab: GitLab Community Edition 12.2.1 2.jenkins: 3.Mac kubernetes: v1.24.2 4.Mac docker: Engine: 20.10.17 Compose: 1.29.2 5.harbor: v2.5.1-b0506782
前提
企业级代码库 Gitlab 企业级CICD持续化集成工具 Jenkins 企业级容器化技术架构：Docker+Kubernetes
以下就开始搭建Harbor，构造企业级私有化镜像仓库
为什么选择Harbor？因为它的功能相对较强，能够基本满足企业级运作
上图先浅看一下
使用离线包进行手动安装
请注意需要安装在有Docker指令的机器上
下载资源包
从 github releases 官方下载offline离线包，这边选取一个稳定版本v2.5.1（online版本需要在线去持续下载资源，为了避免失败，直接下载离线包更为简单）
#通过wget
wget https://github.com/goharbor/harbor/releases/download/v2.5.1/harbor-online-installer-v2.5.1.tgz
#通过页面
#直接点击Asserts中harbor-online-installer-v2.5.1.tgz 下载即可
解压并配置
tgz的包直接解压
tar zxf harbor-online-installer-v2.5.1.tgz ./harbor
解压出来后的目录结构：
-rw-r--r--@ 1 chenzy staff 11347 5 26 23:59 LICENSE
drwxr-xr-x 3 chenzy staff 96 8 29 18:20 common
-rw-r--r--@ 1 chenzy staff 3361 5 26 23:59 common.sh
-rw-r--r-- 1 chenzy staff 6057 8 30 08:25 docker-compose.yml
-rw-r--r--@ 1 chenzy staff 664492716 5 27 00:00 harbor.v2.5.1.tar.gz
-rw-r--r--@ 1 chenzy staff 9917 5 26 23:59 harbor.yml.tmpl
-rwxr-xr-x@ 1 chenzy staff 2500 5 26 23:59 install.sh
-rwxr-xr-x@ 1 chenzy staff 1881 5 26 23:59 prepare
脚本有prepare install common三个，其中common是基础脚本，我们只会直接调用prepare和install两个脚本
其中harbor.yml.tmpl为核心配置的模板，我们可以直接修改文件名称，或者拷贝一个文件来作为核心配置文件，文件内容如下：
# 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.
# 以下主要填写仓库的IP或域名，最好为域名形式
hostname: 127.0.0.1
# http related config
# 以下为HTTP的配置形式
http:
# port for http, default is 80. If https enabled, this port will redirect to https port
# 默认80，基本是要调整
port: 18080
# https related config
# 以下为HTTPs的配置形式，正常生产环境需要打开，需要配置https证书
#https:
# https port for harbor, default is 443
#port: 443
# The path of cert and key files for nginx
#certificate: /your/certificate/path
#private_key: /your/private/key/path
# # Uncomment following will enable tls communication between all harbor components
# internal_tls:
# # set enabled to true means internal tls is enabled
# enabled: true
# # put your cert and key files on dir
# dir: /etc/harbor/tls/internal
# Uncomment external_url if you want to enable external proxy
# And when it enabled the hostname will no longer used
# external_url: https://reg.mydomain.com:8433
# The initial password of Harbor admin
# It only works in first time to install harbor
# Remember Change the admin password from UI after launching Harbor.
# 以下是Harbor admin的默认密码，可修改
harbor_admin_password: Harbor123
# Harbor DB configuration
database:
# The password for the root user of Harbor DB. Change this before any production use.
# 内置DB的默认密码
password: root123
# The maximum number of connections in the idle connection pool. If it <=0, no idle connections are retained.
max_idle_conns: 100
# The maximum number of open connections to the database. If it <= 0, then there is no limit on the number of open connections.
# Note: the default number of connections is 1024 for postgres of harbor.
max_open_conns: 900
# The default data volume
# 挂载的目录
data_volume: /files/docker/harbor
# Harbor Storage settings by default is using /data dir on local filesystem
# Uncomment storage_service setting If you want to using external storage
# storage_service:
# # ca_bundle is the path to the custom root ca certificate, which will be injected into the truststore
# # of registry's and chart repository's containers. This is usually needed when the user hosts a internal storage with self signed certificate.
# ca_bundle:
# # storage backend, default is filesystem, options include filesystem, azure, gcs, s3, swift and oss
# # for more info about this configuration please refer https://docs.docker.com/registry/configuration/
# filesystem:
# maxthreads: 100
# # set disable to true when you want to disable registry redirect
# redirect:
# disabled: false
# Trivy configuration
#
# Trivy DB contains vulnerability information from NVD, Red Hat, and many other upstream vulnerability databases.
# It is downloaded by Trivy from the GitHub release page https://github.com/aquasecurity/trivy-db/releases and cached
# in the local file system. In addition, the database contains the update timestamp so Trivy can detect whether it
# should download a newer version from the Internet or use the cached one. Currently, the database is updated every
# 12 hours and published as a new release to GitHub.
trivy:
# ignoreUnfixed The flag to display only fixed vulnerabilities
ignore_unfixed: false
# skipUpdate The flag to enable or disable Trivy DB downloads from GitHub
#
# You might want to enable this flag in test or CI/CD environments to avoid GitHub rate limiting issues.
# If the flag is enabled you have to download the `trivy-offline.tar.gz` archive manually, extract `trivy.db` and
# `metadata.json` files and mount them in the `/home/scanner/.cache/trivy/db` path.
skip_update: false
#
# The offline_scan option prevents Trivy from sending API requests to identify dependencies.
# Scanning JAR files and pom.xml may require Internet access for better detection, but this option tries to avoid it.
# For example, the offline mode will not try to resolve transitive dependencies in pom.xml when the dependency doesn't
# exist in the local repositories. It means a number of detected vulnerabilities might be fewer in offline mode.
# It would work if all the dependencies are in local.
# This option doesn’t affect DB download. You need to specify "skip-update" as well as "offline-scan" in an air-gapped environment.
offline_scan: false
#
# insecure The flag to skip verifying registry certificate
insecure: false
# github_token The GitHub access token to download Trivy DB
#
# Anonymous downloads from GitHub are subject to the limit of 60 requests per hour. Normally such rate limit is enough
# for production operations. If, for any reason, it's not enough, you could increase the rate limit to 5000
# requests per hour by specifying the GitHub access token. For more details on GitHub rate limiting please consult
# https://developer.github.com/v3/#rate-limiting
#
# You can create a GitHub token by following the instructions in
# https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line
#
# github_token: xxx
jobservice:
# Maximum number of job workers in job service

# Maximum retry count for webhook job

local:
# Log files are rotated log_rotate_count times before being removed. If count is 0, old versions are removed rather than rotated.
rotate_count: 50
# Log files are rotated only if they grow bigger than log_rotate_size bytes. If size is followed by k, the size is assumed to be in kilobytes.
# If the M is used, the size is in megabytes, and if G is used, the size is in gigabytes. So size 100, size 100k, size 100M and size 100G
# are all valid.
rotate_size: 200M
# The directory on your host that store log

将Harbor仓库地址配置在Docker的代理仓库地址中
找到自己当前部署Docker daemon.json所在目录
cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"],
"insecure-registries" : ["127.0.0.1:18080"]
}
配置保存后，需要重新加载启动一下Docker服务使其生效
启动Harbor
#使用当前目录下install指令即可启动
./install.sh
如果修改了harbor.yml则需要先执行 prepare指令，再执行install指令
此外还可以在系统上将服务固定下来，不用手动启动，将其设置为基于docker服务的系统服务
