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：

资源	最低限度	推荐的
CPU	2核	4 核
内存	4GB	8 GB
磁盘	40 GB	160 GB

最低软件要求：

软件	版本	描述
Docker engine	版本 17.06.0-ce+ 或更高版本	有关安装说明，请参阅 Docker 引擎文档
Docker Compose	版本 1.18.0 或更高版本	有关安装说明，请参阅 Docker Compose 文档
OpenSSL	最新的优先	用于为 Harbor 生成证书和密钥

Harbor 要求在目标主机上打开以下端口：

端口号	协议	描述
443	HTTPS	Harbor 门户和核心 API 接受此端口上的 HTTPS 请求。您可以在配置文件中更改此端口。
4443	HTTPS	与 Harbor 的 Docker 内容信任服务的连接。仅在启用 Notary 时才需要。您可以在配置文件中更改此端口。
80	HTTP	Harbor 门户和核心 API 接受此端口上的 HTTP 请求。您可以在配置文件中更改此端口。

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
http:
  # 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
# 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.
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.
#   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

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
