How To Access Your 2FA Docker Hub Account From The Command Line

Note: If you have two-factor authentication (2FA) enabled on your account, you must create at least one personal access token. Otherwise, you will be unable to log in to your account from the Docker CLI.
This article describes our recommendations for how to set up your Git and GitHub credentials. Our goal is a setup that works well for usethis and for other tools you may be using, such as command line Git and Git clients (including, but not limited to, RStudio).
Permission for shared drives are tied to the credentials you provide here. Ifyou run docker commands under a different username than the one configuredhere, your containers cannot access the mounted volumes.
Note: Some users reported problems connecting to Docker Hub on Docker Desktop Stable version. This would manifest as an error when trying to rundocker commands that pull images from Docker Hub that are not alreadydownloaded, such as a first time run of docker run hello-world. If youencounter this, reset the DNS server to use the Google DNS fixed address:126.96.36.199. For more information, seeNetworking issues in Troubleshooting.
By default, Kubernetes containers are hidden from commands like dockerservice ls, because managing them manually is not supported. To make themvisible, select Show system containers (advanced) and click Apply.Most users do not need this option.
Select Sign in /Create Docker ID from the Docker Desktop menu to access your Docker Hub account. Once logged in, you can access your Docker Hub repositories directly from the Docker Desktop menu.
I create docker image for testing in my Jenkins pipeline, uploading this to Docker hub and deploy those to Kubernetes. At the end of the testing process, I want to delete the test image from Docker hub (not from test machine). How do I delete docker hub image from command line?
You can delete any from your Docker Hub by using curl and REST API to the Docker Hub website (at ) rather that to the Docker Hub registry (at docker.io). So if you are not afraid of using an undocumented API, this currently works:
The Container registry stores container images within your organization or personal account, and allows you to associate an image with a repository. You can choose whether to inherit permissions from a repository, or set granular permissions independently of a repository. You can also access public container images anonymously.
When you first publish a package, the default visibility is private. When a package is linked to a repository, the package visibility is dependent on the repository's visibility. To change the visibility or set access permissions, see "Configuring a package's access control and visibility." You can link a published package to a repository using the user interface or command line. For more information, see "Connecting a repository to a package."
An important consideration: when you enable WSL and install a Linux distribution, you are installing a new file system, separated from the Windows NTFS C:\ drive on your machine. In Linux, drives are not given letters. They are given mount points. The root of your file system / is the mount point of your root partition, or folder, in the case of WSL. Not everything under / is the same drive. For example, on my laptop, I've installed two version of Ubuntu (20.04 and 18.04), as well as Debian. If I open those distributions, select the home directory with the command cd ~, and then enter the command explorer.exe ., Windows File Explorer will open and show me the directory path for that distribution.
If you are seeking to access the Windows file directory from your WSL distribution command line, instead of C:\Users\username, the directory would be accessed using /mnt/c/Users/username, because the Linux distribution views your Windows file system as a mounted drive.
Now any git operation you perform within your WSL distribution will use GCM. If you already have credentials cached for a host, it will access them from the credential manager. If not, you'll receive a dialog response requesting your credentials, even if you're in a Linux console.
It will show all generic credentials. Find your GitHub URL and click on that. Now click on the edit button. And then add the personal access token generated from GitHub into the password field. And click on the Save button.
Then, the next time you try to push or pull, Git will prompt you for a username and password. For the username, enter your GitHub username, and for the password, generate a new personal access token on the appropriate settings page and paste it into the password field. If you're working from the command line, you may not see any indication that the password was successfully pasted; this is normal, so just hit Enter afterwards.

The registry cannot be listed as an insecure registry (seeDocker Daemon). Docker Desktop ignorescertificates listed under insecure registries, and does not send clientcertificates. Commands like docker run that attempt to pull from the registryproduce error messages on the command line, as well as on the registry.
Docker stores your credentials insecurely in ~/.docker/config.json by default. You can add more protection by integrating a credential helper utility. Enabled helpers get to handle credential store, get, and erase commands issued by Docker in response to CLI operations.
Getting the Docker CLI connected to your Docker Hub account or a private registry is usually best handled by the docker login command. You can supply credentials interactively, as flags, or via a piped-in password file. Make sure you use a Personal Access Token instead of your password if you have two-factor authentication enabled.
GitHub is a cloud-based service for storing and sharing source code. Using GitHub with Visual Studio Code lets you share your source code and collaborate with others right within your editor. There are many ways to interact with GitHub, for example, via their website at or the Git command-line interface (CLI), but in VS Code, the rich GitHub integration is provided by the GitHub Pull Requests and Issues extension.
Streamline user access to your apps by enabling the Duo Access Gateway Launcher. The launcher provides a portal from which users can access Duo Access Gateway protected service provider applications or other non-SAML applications configured in Duo with just a click. You can even add bookmarks for organization web sites that don't use Duo authentication.
If you have other Duo-protected web applications that you'd like to link directly from the Duo Access Gateway launcher you can add them in the "Duo Web Applications" configuration section. These can be Duo Network Gateway published internal applications or any other externally accessible browser-based Duo application that shows the inline Duo prompt (like OWA, Confluence, etc.).

The Dependency Proxy makes the most sense as a compliment to CI/CD pipelines. Rather than pulling directly from Docker Hub, you can use the Dependency Proxy to speed up your pipelines, avoid rate limiting, and create security in case of an upstream outage.
Depending on how your scripts and pipelines look you can use these variables in a variety of ways. If you are manually pulling images in the script using docker pull, you can log in and pull like this:
In the event of a lost or wiped phone, it is important to have proper backup methods in place to recover access to your 2FA-enabled account. When you configure 2FA for the first time, you have a few options to ensure that you can recover from a lock out:
If you mount config.json in the manner above, changes from the host system will (generally) not be propagated to therunning container. Mounting files into the Docker daemon uses bind mounts, which are based on inodes. Mostapplications (including docker login and vim) will not directly edit the file, but instead make a copy and replacethe original file, which results in a new inode which in turn breaks the bind mount.As a workaround, you can create a symlink to your config.json file and then mount the symlink in the container. The symlinked file will always have the same inode, which keeps the bind mount intact and will ensure changesto the original file are propagated to the running container (regardless of the inode of the source file!).
If you mount the config file as described above, be sure to also prepend the URL for the registry when starting up yourwatched image (you can omit the https://). Here is a complete docker-compose.yml file that starts up a docker containerfrom a private repo at Docker Hub and monitors it with watchtower. Note the command argument changing the interval to30s rather than the default 24 hours. 2b1af7f3a8
