Harbor 1.8的安装和使用

说明

之前我们搭建了k8s，那么就会有另一个问题，我们的那些镜像文件不想放在公有云里，私有云镜像多快多安全啊。我找到的是Harbor这个镜像的仓库，由于内网环境不需要配置ssl就选用了1.8的版本，再往上的话就需要配置ssl了！使用http的过程踩了一些坑，在这里记录一下。

准备

Harbor版本1.8.0 下载地址https://github.com/goharbor/harbor/releases(由于某些原因，国内不太好下载)，离线安装包我放七牛云了->harbor-offline-installer-v1.8.0.tgz

postgres版本11.8 安装教程可以看我以前的博客->Postgres11在CentOS7下的安装与使用

redis&docker&docker-compose的安装就不说了

快速开始

下载好Harbor的离线安装包后，解压

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

让docker支持http，添加--insecure-registry参数

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

重启docker

systemctl daemon-reload
systemctl restart docker

编辑解压文件里的harbor.yml

vim harbor.yml

内容如下，需要修改hostname，把database注掉，启用外部数据库external_database（仅支持postgres）记得先创建库哦，启用外部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: <服务器ip>

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

# 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/

# Log configurations

  # 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:

# Uncomment external_redis if using external Redis server

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

编辑保存后执行

sh install.sh

看到下面的信息说明你成功了，docker-compose ps也能看到运行情况，如果需要停止服务使用docker-compose stop，启动使用docker-compose up -d，还需要移除创建的容器的话使用docker-compose down -v

[Step 3]: starting Harbor ...

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

Now you should be able to visit the admin portal at http://<服务器ip>.

如果出错，没成功启动，请查看/var/log/harbor/目录下的log日志文件排错，我遇到一个下面的错误，可能是因为我反复删建的原因，把整个库删掉重新创建就好了

 然后就可以使用浏览器登录管理界面了访问你服务器ip即可，创建一个新的用户用于等会儿测试docker login

创建一个新的项目用于等会儿测试docker push

 好的，服务端准备完毕，开始配置客户端

测试login

我windows使用的是docker-toolbox，我们同样需要设置--insecure-registry参数，不然你会看到下面的错误

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

欸，又得改docker-toolbox的参数了，上次改这个是因为和内网网段冲突(•́へ•́╬)有兴趣的可以查看内网环境下修改Docker Toolbox的访问地址并暴露端口。网上查阅资料，发现有在profile文件配置镜像地址的，猜测应该就是在这里加，打开toolbox开始测试，如果提示profile是ReadOnly，用sudo chmod 777 profile即可

docker-machine ssh default
vi /var/lib/boot2docker/profile
# 在--label provider=virtualbox下面再加上参数insecure-registry
--insecure-registry=<服务器ip>

保存文件，输入exit退出ssh，重启docker

docker-machine restart default

然后使用docker login登录，欸，果然成功了，这参数还真是难找

docker login <服务器ip>

看到Login Succeeded说明你就成功了！

测试push

网页打开项目，点击"推送镜像"可以看到例子

例如我们想推一个mysql镜像到服务器上去可以这么操作

# 打tag
docker tag yunlingfly/mysql:5.7.17 服务器ip/yunlingfly/mysql:5.7.17
# 推镜像
docker push 服务器ip/yunlingfly/mysql:5.7.17

然后就可以在这个项目下面看到你推的镜像啦(ಥ_ಥ)
