Docker Desktop v3.0 已于前两周正式公布，从这个版本起，Docker 官网承诺每次的更新将以增量更新的形式来提供，以便缩小下载包的体积，晋升效率。
除了将 Docker Engine 更新至 v20.10.0 外，也对其余的依赖做了更新，如下图：
最吸引我的是本次新增的 Docker Hub Tool v0.2.0，它是 Docker 官网提供的 Docker Hub CLI 工具，具备治理 DockerHub 上的帐号，镜像等相干资源的能力。
以下，我来为你介绍下 Hub Tool 的次要性能。
(MoeLove) ➜ hub-tool -h
A tool to manage your Docker Hub images
Usage:
hub-tool
hub-tool [command]
Available Commands:
account Manage your account
help Help about any command
login Login to the Hub
logout Logout of the Hub
org Manage organizations
repo Manage repositories
tag Manage tags
token Manage Personal Access Tokens
version Version information about this tool
Flags:
-h, --help help for hub-tool
--verbose Print logs
--version Display the version of this tool
Use "hub-tool [command] --help" for more information about a command. 从一级菜单来看，次要性能包含：
- 登录 / 登出 DockerHub;
- 账户相干治理性能；
- 组织相干治理性能；
- 仓库和 tag 的相干治理性能；
- token 的相干治理性能；
以后我应用的是最新版本 v0.2.0。
(MoeLove) ➜ hub-tool version
Version: v0.2.0
Git commit: 0edf43ac9091e7cac892cbc4cbc6efbafb665aa4登录 / 退出
登录 / 退出只有执行 hub-tool login 或者 hub-tool logout 即可。
但这里须要留神的是 Hub Tool 并没有应用 Docker Desktop 默认的用户凭证 ，也就是说，即便你在 Docker Desktop 中曾经登录了帐号，你同样还是须要再次在终端下执行 login 操作。
对于为何没有共用用户凭证的问题，我跟 Docker Inc. 的产品经理聊过，是因为以后 Hub Tool 还是一个独立的 CLI 工具，并没有与 docker CLI 进行集成，也临时没想好要如何集成。等真正要集成进 docker CLI 的时候，就会间接共用用户凭证了。
(MoeLove) ➜ hub-tool login
Username: moelove
Password:账户治理
账户治理的两个性能：
- 查看账户信息；
- 查看以后账户下的流量限度 , 这是我集体感觉比拟有用的一个性能；
(MoeLove) ➜ hub-tool account
Manage your account
Usage:
hub-tool account
hub-tool account [command]
Available Commands:
info Print the account information
rate-limiting Print the rate limiting information
Flags:
-h, --help help for account
Global Flags:
--verbose Print logs
Use "hub-tool account [command] --help" for more information about a command.
(MoeLove) ➜ hub-tool account rate-limiting
Limit: 200, 6 hours window
Remaining: 200, 6 hours window

能够看到，hub-tool org 的性能就是展现一些相干信息了。
(MoeLove) ➜ hub-tool org
Manage organizations
Usage:
hub-tool org
hub-tool org [command]
Available Commands:
ls List all the organizations
members List all the members in an organization
teams List all the teams in an organization
Flags:
-h, --help help for org
Global Flags:
--verbose Print logs
Use "hub-tool org [command] --help" for more information about a command.
(MoeLove) ➜ hub-tool org ls
NAMESPACE NAME MY ROLE TEAMS MEMBERS仓库和 tag 治理
因为这两个都和镜像有间接的关系，我就聚合到一起介绍了。
- 对 repo 的查问和删除性能：
(MoeLove) ➜ hub-tool repo -h
Manage repositories
Usage:
hub-tool repo
hub-tool repo [command]
Available Commands:
ls List all the repositories from your account or an organization
rm Delete a repository
Flags:
-h, --help help for repo
Global Flags:
--verbose Print logs
Use "hub-tool repo [command] --help" for more information about a command.
(MoeLove) ➜ hub-tool repo ls
REPOSITORY DESCRIPTION LAST UPDATE PULLS STARS PRIVATE
taobeier/saythx-work 2 years ago 56989 0 false
...
(MoeLove) ➜ hub-tool repo ls -h
List all the repositories from your account or an organization
Usage:
hub-tool repo ls [ORGANIZATION]
Aliases:
ls, list
Flags:
--all Fetch all available repositories
--format string Print values using a custom format ("json")
-h, --help help for ls
Global Flags:
--verbose Print logs - 对 tag 的列表，查问，查看具体等性能。这里 能够看到 tag 最近一次的 Push/Pull 操作，如果明年 Docker 开始履行镜像保留策略的话，我倡议你关注一下 ；
(MoeLove) ➜ hub-tool tag
Manage tags
Usage:
hub-tool tag [flags]
hub-tool tag [command]
Available Commands:
inspect Show the details of an image in the registry
ls List all the images in a repository
rm Delete a tag in a repository
Flags:
-h, --help help for tag
Global Flags:
--verbose Print logs
Use "hub-tool tag [command] --help" for more information about a command.
See 'hub-tool tag ls --help'.
Usage: hub-tool tag ls [OPTION] REPOSITORY
List all the images in a repository
(MoeLove) ➜ hub-tool tag ls taobeier/saythx-work

以上就是对于 Docker 新公布的 Hub Tool 的全副性能介绍了。
以后它是随着 Docker Desktop 一起发行的，所以 Linux 下临时没有。然而打算会尽快开源。敬请期待！
