Harbor客户端工具，命令行对Harbor进行管理

一、Harborclient工具简介

项目地址: https://github.com/int32bit/harborclient

创新互联公司是一家专业的成都网站建设公司，我们专注网站设计、成都网站建设、网络营销、企业网站建设，买链接，1元广告为企业客户提供一站式建站解决方案，能带给客户新的互联网理念。从网站结构的规划UI设计到用户体验提高，创新互联力求做到尽善尽美。

Harborclient是Harbor的第三方扩展开源工具，正弥补Harbor不足，它适合开发和运维人员管理镜像仓库、项目等资源，包含的特性如下：

  • harborclient参考了OpenStack命令行工具的优秀架构和设计模式，使用也和OpenStack命令行非常类似。
  • harborclient通过子命令划分不同的功能，并且所有功能是可扩展的，增加功能只需要在client下增加do_xxx方法即可。主模块会自动发现并注册子命令。
  • 相比OpenStack的命令行工具，精简了部分复杂功能，重新设计了大多数接口，暴露的API更直观和易用。
  • 支持DEBUG模式查看Harbor API调用过程，便于调试追踪。
  • 支持timings选项，能够报告API请求响应时间，便于测试Harbor API性能。
  • 支持https。

二、安装Harborclient(docker)

2.1 镜像拉取/制作

harborclient托管在docker hub中，可以直接拉取已经构建的镜像到本地:

$ docker pull krystism/harborclient

docker hub中的镜像不一定是最新的，建议从源码中build镜像，在项目根下运行:

$ git clone https://github.com/int32bit/harborclient
$ docker build -t yourname/harborclient .

2.2 启动容器

$ docker run -itd \
 -e HARBOR_URL="https://192.168.2.19:443" \
 -e HARBOR_USERNAME="admin" \
 -e HARBOR_PASSWORD="Harbor12345" \
 -e HARBOR_PROJECT=1 \
 --rm krystism/harborclient
+---------+----------+----------+----------------------+--------------+---------------+
| user_id | username | is_admin |        email         |   realname   |    comment    |
+---------+----------+----------+----------------------+--------------+---------------+
|    1    |  admin   |    1     |  admin@example.com   | system admin |   admin user  |
|    11   | int32bit |    0     | int32bit@example.com |   int32bit   | for int32bit  |
+---------+----------+----------+----------------------+--------------+---------------+

HARBOR_URL:  指定Harbor地址；

HARBOR_USERNAME: 指定Harbor用户名；

HARBOR_PASSWORD: 指定Harbor用户密码；

HARBOR_PROJECT:  指定项目ID号；

2.3 设置命令自动补全

harborclient支持命令补全，以bash为例，需要首先安装bash-completion，然后执行以下命令配置自动补全：

$ sudo yum install  -y bash-completion
$ complete -W $(harbor bash-completion) harbor

此时可以通过tab键自动补全参数以及子命令了。

三、使用

3.1 子命令集参数说明

  • 子命令

get-cert:

get-conf: 查看harbor信息;

info:  查看harbor信息;

job-list:

job-log:

  • 参数

--debug： 详细打印调用的harbor API以及参数，并显示response信息；

--timings： 参数将打印命令执行时调用的所有API列表并报告响应时间；

--timeout： 参数可以设置允许的最长响应时间（单位: 秒），支持浮点数，超过这个时间未响应将导致请求超时异常；

3.2 使用https

harborclient支持https，对应使用https的Harbor可以通过--os-cacert选项指定CA证书，也可以通过--insecure跳过认证校验，相当于curl -k命令。

$ harbor list   #使用https的harbor会出现该报错
CommandError: Unable to authorize user 'admin': Certificate verify failed, please use '--os-cacert' option to specify a CA bundle file to use in verifying a TLS (https) server certificate or use '--insecure' option to explicitly allow client to perform insecure TLS (https) requests.
$ harbor --insecure list

3.3 使用案例

$ harbor --insecure user-create \
 --username lidabai \
 --password lidabai666 \
 --email lidabai@example.com \
 --realname newuser \
 --comment "I am a new user"
Create user 'lidabai' successfully.    #提升创建成功

--username: 指定要创建的用户名（必须）；

--password: 指定创建用户的用户密码（必须）；

--email：指定邮箱；

--comment：描述信息；

3.4 增加自定义子命令

以增加一个echo子命令为例，首先在harborclient/v2目录下新创建一个模块文件tests.py，实现echo方法，如下:

from harborclient import base
class TestManager(base.Manager):
    def echo(self, message):
        return message

在harborclient/v2/client中注册TestManager：

... # 省略其它import
from harborclient.v2 import tests
class Client(object):
    def __init__(self,
                 username=None,
                 password=None,
                 project=None,
                 baseurl=None,
                 insecure=False,
                 cacert=None,
                 api_version=None,
                 *argv,
                 **kwargs):
        ... # 省略其它Manager
        self.tests = tests.TestManager(self)

最后在harborclient/v2/shell.py中注册新的子命令，注意在shell.py中所有的do_xx方法都会对应一条子命令，转化规则为:

do_a_b_c => a-b-c
比如:
do_user_list => user-list
do_project_show => project-show

方法的doc文档将转化为echo子命令的帮助信息。因此新增echo子命令，只需要在shell.py中新增do_echo方法：

@utils.arg(
    '--message',
    metavar='',
    dest='message',
    required=True,
    help='The message to print.')
def do_echo(cs, args):
    """Print a message."""
    message = cs.tests.echo(args.message)
    print(message)

此时echo子命令就实现了。查看帮助信息:

$ harbor  help echo
usage: harbor echo --message 

Print a message.

Optional arguments:
  --message   The message to print.
