Harbor 安装条件
官网给出了安装需要的最低硬件和软件的条件：https://goharbor.io/docs/2.0.0/install-config/installation-prereqs/
最低硬件要求：
最低软件要求：
Harbor 要求在目标主机上打开以下端口：
在线安装和离线安装
可以从 官方发布页面下载 Harbor 安装程序。下载在线安装程序或离线安装程序。
- 在线安装程序：在线安装程序从 Docker 中心下载 Harbor 镜像。因此，安装程序的尺寸非常小。
- 离线安装程序：如果要部署 Harbor 的主机没有连接到 Internet，请使用离线安装程序。离线安装程序包含预先构建的映像，因此它比在线安装程序大
在线和离线安装程序的安装过程几乎相同。
这里我主要使用离线安装，因为在线安装因为墙、内部网络等原因，有的同学会下载很慢，而离线安装包都包含了预先构建的镜像，所以直接现在离线安装包最好！
离线安装
到 官方发布 页面下载离线安装包：
下载后将压缩包上传到服务器使用命令tar -zxf harbor-offline-installer-v2.4.2.tgz解压，解压后如下图：
解压后在当前的解压路径可以得到文件夹harbor，cd harbor 进文件夹：
可以看到文件夹有一堆文件，其中最主要的是 harbor.yml.tmpl和 install.sh ，他们分别是配置文件和安装执行文件。
# 复制并重命名一份新的配置文件
cp harbor.yml.tmpl harbor.yml
# 使用 vim 编辑配置文件，如果提示找不到vim ，使用以下命令安装 vim
# ubuntu 使用 sudo apt-get install vim
# redHat/Fedora/CentOS 使用 yum install vim
vim harbor.yml # 或者使用 vi harbor.yml 编辑
打开harbor.yml，最主要是更改一下几点，其他的保持默认即可：
harbor.yml示例模板：
# 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: 192.168.0.2
# http related config

# port for http, default is 80. If https enabled, this port will redirect to https port
port: 8088
# 不使用HTTPS
# https related config

# internal_tls:

# Uncomment external_url if you want to enable external proxy

# 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.
harbor_admin_password: Harbor12345
# Harbor DB configuration
database:
# The password for the root user of Harbor DB. Change this before any production use.
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
data_volume: /mnt/harbor/data
# 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.

# 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

编辑完成后按ESC，然后使用命令:wq保存并推出。
然后继续用命令执行安装./install.sh。
安装过程（从别人博客上扒下来的图）：
当出现红箭头指向的提示的时候，就表示安装成功了！
然后根据在harbor.yml文件中配置的端口与IP地址(或域名)进行访问
现在Harbor已经可以使用了！
由于我部署的时候没有使用HTTPS，所以使用docker登录的时候会出现一下异常信息（还是借的别人的图）：
原因：Docker自从1.3.X之后docker registry交互默认使用的是HTTPS，但是搭建私有镜像默认使用的是HTTP服务，所以与私有镜像交时出现以上错误。
解决办法：
找到docker 的 daemon.json 配置文件，CentOS 7 的路径：/etc/docker/daemon.json（系统版本不同所处位置不同，其他版本的请自行百度），如果路径下没有这个文件自己创建即可。然后再配置文件里加上：
{
// docker 镜像下载地址
"registry-mirrors": ["https://mirror.ccs.tencentyun.com"],
// 不安全的镜像仓库（此处配置Harbor 的地址+端口号）
"insecure-registries": ["192.168.0.2:8088"],
}
操作完后让这个文件生效：
a.修改完成后reload配置文件
sudo systemctl daemon-reload
b.重启docker服务
sudo systemctl restart docker.service
