Docker Desktop V3.0 has been officially released in the past two weeks. From this release, Docker officially promises that each update will be provided in an incremental way to reduce the volume of downloaded packages and improve efficiency.

In addition to updating the Docker Engine to V20.10.0, other dependencies have also been updated, as shown below:

What attracts me most is the newly added DockerHub Tool V0.2.0, which is the DockerHub CLI Tool officially provided by Docker, with the ability to manage accounts, images and other related resources on DockerHub.

Below, I will introduce the main functions of Hub Tool for you.

(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.

Copy the code

From the perspective of the first-level menu, the main functions include:

  • Log in/out of DockerHub;
  • Account related management functions;
  • Organization related management functions;
  • Warehouse and tag related management functions;
  • Related management functions of token;

I’m currently using the latest version, V0.2.0.

Log in/Out

To login or out, run hub-tool login or hub-tool logout.

However, it should be noted that the Hub Tool does not use the Docker Desktop default user credentials, that is, even if you have logged in to the Docker Desktop account, you still need to login to the terminal again.

As for why there is no shared user credentials, I have communicated with Docker Inc. The reason is that the current Hub Tool is still an independent CLI Tool and has not been integrated with docker CLI, and I have not yet figured out how to integrate it. When it is really integrated into the DOCker CLI, user credentials will be directly shared.

Account management

Two functions of account management:

  • View account information;
  • Check the traffic limits under your current account, which I personally find useful;
(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

  -h, --help   help for account

Global Flags:
      --verbose   Print logs

Organization and management

As you can see, the purpose of the Hub-tool org is to show some information about it.

(MoeLove) ➜  hub-tool org
Manage organizations

Usage:
  hub-tool org
  hub-tool org [command]

Available Commands:
  ls          List all the organizations

Global Flags:
      --verbose   Print logs

Warehouse and tag management

Since both of these are directly related to mirror images, I’m going to put them together.

  • Query and delete functions for the REPO:
(MoeLove) ➜  hub-tool repo -h
Manage repositories

Usage:
  hub-tool repo
  hub-tool repo [command]

Available Commands:

  • Tag list, query, view details and other functions. Here you can see the latest Push/Pull operation of tag. If Docker starts mirroring next year, I suggest you take a look.

conclusion

The above is all about the newly released Hub Tool of Docker. It is currently shipped with Docker Desktop, so it is not available for Linux. But the plan is to open source soon. Stay tuned!
