Harbor 1.8的安裝和使用

說明

之前我們搭建了k8s，那麼就會有另一個問題，我們的那些鏡像文件不想放在公有云裏，私有云鏡像多快多安全啊。我找到的是Harbor這個鏡像的倉庫，由於內網環境不需要配置ssl就選用了1.8的版本，再往上的話就需要配置ssl了！使用http的過程踩了一些坑，在這裏記錄一下。

準備

Harbor版本1.8.0 下載地址https://github.com/goharbor/harbor/releases(由於某些原因，國內不太好下載)，離線安裝包我放七牛雲了->harbor-offline-installer-v1.8.0.tgz

postgres版本11.8 安裝教程可以看我以前的博客->Postgres11在CentOS7下的安裝與使用

redis&docker&docker-compose的安裝就不說了

快速開始

下載好Harbor的離線安裝包後，解壓

tar -zxf harbor-offline-installer-v1.8.0.tgz
cd harbor

讓docker支持http，添加--insecure-registry參數

vim /usr/lib/systemd/system/docker.service
# 找到ExecStart添加--insecure-registry=<你服務器ip>
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock --exec-opt native.cgroupdriver=systemd --insecure-registry=<你服務器ip>

重啓docker

systemctl daemon-reload
systemctl restart docker

編輯解壓文件裏的harbor.yml

vim harbor.yml

內容如下，需要修改hostname，把database注掉，啓用外部數據庫external_database（僅支持postgres）記得先創建庫哦，啓用外部redisexternal_redis

# 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: <服務器ip>

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

# https related config
# https:
#   # https port for harbor, default is 443
#   port: 443
#   # The path of cert and key files for nginx

# 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/

# Clair configuration
clair: 
  # The interval of clair updaters, the unit is hour, set to 0 to disable the updaters.
  updaters_interval: 12

  # Config http proxy for Clair, e.g. http://my.proxy.com:3128
  # Clair doesn't need to connect to harbor internal components via http proxy.

# Log configurations

  level: info
  # 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: /var/log/harbor

#This attribute is for migrator to detect the version of the .cfg file, DO NOT MODIFY!
_version: 1.8.0

# Uncomment external_database if using external database. Currently only support POSTGRES. 
# Four databases are needed to be create first by users for Harbor core, Clair, Notary server 
# and Notary signer. And the tables will be generated automatically when Harbor starting up.
# NOTE: external_database is unable to custom attributes individually, you must do them in block.
external_database:
  harbor:
    host: harbor_db_host
    port: harbor_db_port
    db_name: harbor_db_name
    username: harbor_db_username
    password: harbor_db_password

# Uncomment external_redis if using external Redis server
external_redis:
  host: <redis-ip>
  port: 6379
  password:
  # db_index 0 is for core, it's unchangeable
  registry_db_index: 1

  chartmuseum_db_index: 3

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

編輯保存後執行

sh install.sh

看到下面的信息說明你成功了，docker-compose ps也能看到運行情況，如果需要停止服務使用docker-compose stop，啓動使用docker-compose up -d，還需要移除創建的容器的話使用docker-compose down -v

✔ ----Harbor has been installed and started successfully.----

Now you should be able to visit the admin portal at http://<服務器ip>.
For more details, please visit https://github.com/goharbor/harbor .

如果出錯，沒成功啓動，請查看/var/log/harbor/目錄下的log日誌文件排錯，我遇到一個下面的錯誤，可能是因爲我反覆刪建的原因，把整個庫刪掉重新創建就好了

 然後就可以使用瀏覽器登錄管理界面了訪問你服務器ip即可，創建一個新的用戶用於等會兒測試docker login

創建一個新的項目用於等會兒測試docker push

 好的，服務端準備完畢，開始配置客戶端

測試login

我windows使用的是docker-toolbox，我們同樣需要設置--insecure-registry參數，不然你會看到下面的錯誤

$ docker login 服務器ip
Username: yunlingfly
Password:
Error response from daemon: Get https://服務器ip/v2/: dial tcp 服務器ip:443: connect: connection refused

欸，又得改docker-toolbox的參數了，上次改這個是因爲和內網網段衝突(•́へ•́╬)有興趣的可以查看內網環境下修改Docker Toolbox的訪問地址並暴露端口。網上查閱資料，發現有在profile文件配置鏡像地址的，猜測應該就是在這裏加，打開toolbox開始測試

docker-machine ssh default
vi /var/lib/boot2docker/profile
# 在--label provider=virtualbox下面再加上參數insecure-registry
--insecure-registry=<服務器ip>

保存文件，輸入exit退出ssh，重啓docker

docker-machine restart default

然後使用docker login登錄，欸，果然成功了，這參數還真是難找

docker login <服務器ip>

看到Login Succeeded說明你就成功了！

測試push

網頁打開項目，點擊"推送鏡像"可以看到例子

例如我們想推一個mysql鏡像到服務器上去可以這麼操作

# 打tag
docker tag yunlingfly/mysql:5.7.17 服務器ip/yunlingfly/mysql:5.7.17
# 推鏡像
docker push 服務器ip/yunlingfly/mysql:5.7.17

然後就可以在這個項目下面看到你推的鏡像啦(ಥ_ಥ)
