Harbor搭建docker私有仓库

Harbor搭建docker私有仓库

本文最后更新于2022.11.5

为什么需要Docker私有仓库

Docker Hub这种公共仓库里面的镜像是所有人都可以拉取,所以不方便上传我们私有的镜像,但是私有仓库必须要有账号密码才能pull或push镜像,可以实现一些特殊需求,比如定时备份镜像等。


Harbor是在github开源的私有仓库,项目地址:https://github.com/goharbor/harbor


Google Drive资源团队盘购买:https://goto.haogeboke.com/,上百T资源。

搭建

Harbor的搭建非常简单:

  1. 点击这里下载release。
  2. 配置config文件,在Harbor根目录执行:
cp harbor.yml.tmpl harbor.yml
nano harbor.yml #建议注释掉https配置部分,后面通过反代来配置。

示例配置文件:

# 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: yourdomain.com

# http related config
http:
  # port for http, default is 80. If https enabled, this port will redirect to https port
  port: 8090

# https related config
https:
  # https port for harbor, default is 443
  port: 44390
  # The path of cert and key files for nginx
  certificate: /etc/nginx/ssl/yourdomain.com/fullchain.pem
  private_key: /etc/nginx/ssl/yourdomain.com/privkey.pem

# # 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://yourdomain.com

# 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: passwd

# Harbor DB configuration
database:
  # The password for the root user of Harbor DB. Change this before any production use.
  password: dbpasswd
  # 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: /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
  #
  # github_token: xxx

jobservice:
  # Maximum number of job workers in job service
  max_job_workers: 10

notification:
  # Maximum retry count for webhook job
  webhook_job_max_retry: 10

chart:
  # Change the value of absolute_url to enabled can enable absolute url in chart
  absolute_url: disabled

# Log configurations
log:
  # options are debug, info, warning, error, fatal
  level: info
  # configs for logs in local storage
  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
    location: /harbor/log/harbor

  # Uncomment following lines to enable external syslog endpoint.
  # external_endpoint:
  #   # protocol used to transmit log to external endpoint, options is tcp or udp
  #   protocol: tcp
  #   # The host of external endpoint
  #   host: localhost
  #   # Port of external endpoint
  #   port: 5140

#This attribute is for migrator to detect the version of the .cfg file, DO NOT MODIFY!
_version: 2.6.0

# Uncomment external_database if using external database.
# external_database:
#   harbor:
#     host: harbor_db_host
#     port: harbor_db_port

# Uncomment uaa for trusting the certificate of uaa instance that is hosted via self-signed cert.
# uaa:
#   ca_file: /path/to/ca

# Global proxy
# Config http proxy for components, e.g. http://my.proxy.com:3128
# Components doesn't need to connect to each others via http proxy.
# Remove component from components array if want disable proxy
# for it. If you want use proxy for replication, MUST enable proxy
# for core and jobservice, and set http_proxy and https_proxy.
# Add domain to the no_proxy field, when you want disable proxy
# for some special registry.
proxy:
  http_proxy:
  https_proxy:
  no_proxy:
  components:
    - core
    - jobservice
    - trivy

# metric:
#   enabled: false
#   port: 9090
#   path: /metrics

# Trace related config
# only can enable one trace provider(jaeger or otel) at the same time,
# and when using jaeger as provider, can only enable it with agent mode or collector mode.
# if using jaeger collector mode, uncomment endpoint and uncomment username, password if needed
# if using jaeger agetn mode uncomment agent_host and agent_port
# trace:
#   enabled: true
#   # set sample_rate to 1 if you wanna sampling 100% of trace data; set 0.5 if you wanna sampling 50% of trace data, and so forth
#   sample_rate: 1
#   # # namespace used to differenciate different harbor services
#   # namespace:
#   # # attributes is a key value dict contains user defined attributes used to initialize trace provider
#   # attributes:
#   #   application: harbor
#   # # jaeger should be 1.26 or newer.
#   # jaeger:
#   #   endpoint: http://hostname:14268/api/traces
#   #   username:
#   #   password:
#   #   agent_host: hostname
#   #   # export trace data by jaeger.thrift in compact mode
#   #   agent_port: 6831
#   # otel:
#   #   endpoint: hostname:4318
#   #   url_path: /v1/traces
#   #   compression: false
#   #   insecure: true
#   #   timeout: 10s

# enable purge _upload directories
upload_purging:
  enabled: true
  # remove files in _upload directories which exist for a period of time, default is one week.
  age: 168h
  # the interval of the purge operations
  interval: 24h
  dryrun: false

# cache layer configurations
# If this feature enabled, harbor will cache the resource
# project/project_metadata/repository/artifact/manifest in the redis
# which can especially help to improve the performance of high concurrent
# manifest pulling.
# NOTICE
# If you are deploying Harbor in HA mode, make sure that all the harbor
# instances have the same behaviour, all with caching enabled or disabled,
# otherwise it can lead to potential data inconsistency.
cache:
  # not enabled by default
  enabled: false
  # keep cache for one day by default
  expire_hours: 24
  1. 修改完成后运行prepare进行初始化:
./prepare
  1. 运行
./install.sh

大功告成!

  1. Harbor实际是由docker驱动的,docker-compose.yml文件在根目录,可以根据需要进行修改。
  2. 每次修改harbor.yml文件后都要运行./prepare进行初始化再./install.sh才能生效。

配置反代

配置反代并添加https(必须步骤,否则会出现奇怪的问题)。
nginx反代配置示例:

location ^~ / {
    proxy_pass http://127.0.0.1:8090; #改成自己端口
    proxy_set_header Host 127.0.0.1:8090; #改成自己端口
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header REMOTE-HOST $remote_addr;
    add_header X-Cache $upstream_cache_status;
    proxy_ignore_headers Set-Cookie Cache-Control expires;
    add_header Cache-Control no-cache;
    set $static_files_app 0;
    if ( $uri ~* \.(gif|png|jpg|css|js|woff|woff2)
   {
    set $static_files_app 1;
    expires 12h;
   }
    if ( $static_files_app = 0 )
  {
    add_header Cache-Control no-cache;
   }
   }

需要注意的是私有仓库对证书要求比较严格,证书链必须完整,也就是包含CA的fullchain证书!!!


使用

docker命令的使用可以自行搜索。
仅示例打包正在运行的镜像并push到私有仓库:

docker login YOURDOMAIN.COM #输入你的账号、密码
docker commit CONTAINER_ID YOURDOMAIN.COM/PROJECT_NAME/*/TAG_NAME
docker push YOURDOMAIN.COM/PROJECT_NAME/*/TAG_NAME
