## Learning Center
|
||
|
||
The Learning Center helps you get started with quick in-app walkthroughs and other resources for learning about Docker.
|
||
|
||
To access the Learning Center, select the **Learning Center** tab in Docker
|
||
Desktop.
|
||
|
||
|
||
|
||
For a more detailed guide about getting started, see
|
||
[Get started](../get-started/index.md).
|
||
|
||
## Sign in to Docker Desktop
|
||
|
||
Docker recommends that you authenticate using the **Sign in** option in the top-right corner of the Docker Dashboard.
|
||
|
||
Once logged in, you can access your Docker Hub repositories directly from Docker Desktop.
|
||
|
||
Authenticated users get a higher pull rate limit compared to anonymous users. For example, if you are authenticated, you get 200 pulls per 6 hour period, compared to 100 pulls per 6 hour period per IP address for anonymous users. For more information, see [Download rate limit](../docker-hub/download-rate-limit.md).
|
||
|
||
In large enterprises where admin access is restricted, administrators can [Configure registry.json to enforce sign-in](../docker-hub/configure-sign-in.md). Enforcing developers to authenticate through Docker Desktop also allows administrators to improve their organization’s security posture for containerized development by taking advantage of [Hardened Desktop](hardened-desktop/index.md).
|
||
|
||
> **Note**
|
||
>
|
||
> Docker Desktop automatically signs you out after 90 days, or after 30 days of inactivity.
|
||
|
||
### Credentials management for Linux users
|
||
|
||
Docker Desktop relies on [`pass`](https://www.passwordstore.org/){: target="_blank" rel="noopener" class="_"} to store credentials in gpg2-encrypted files.
|
||
Before signing in to Docker Hub from the Docker Dashboard or the Docker menu, you must initialize `pass`.
|
||
Docker Desktop displays a warning if you've not initialized `pass`.
|
||
|
||
You can initialize pass by using a gpg key. To generate a gpg key, run:
|
||
|
||
``` console
|
||
$ gpg --generate-key
|
||
```
|
||
|
||
The following is an example similar to what you see once you run the previous command:
|
||
|
||
```console
|
||
...
|
||
GnuPG needs to construct a user ID to identify your key.
|
||
|
||
Real name: Molly
|
||
Email address: molly@example.com
|
||
You selected this USER-ID:
|
||
"Molly <molly@example.com>"
|
||
|
||
Change (N)ame, (E)mail, or (O)kay/(Q)uit? O
|
||
...
|
||
pub rsa3072 2022-03-31 [SC] [expires: 2024-03-30]
|
||
<generated gpg-id public key>
|
||
uid Molly <molly@example.com>
|
||
sub rsa3072 2022-03-31 [E] [expires: 2024-03-30]
|
||
```
|
||
|
||
To initialize `pass`, run the following command using the public key generated from the previous command:
|
||
|
||
```console
|
||
$ pass init <generated gpg-id public key>
|
||
```
|
||
The following is an example similar to what you see once you run the previous command:
|
||
|
||
```console
|
||
mkdir: created directory '/home/molly/.password-store/'
|
||
Password store initialized for <generated gpg-id public key>
|
||
```
|
||
|
||
Once you initialize `pass`, you can sign in on the Docker Dashboard and pull your private images.
|
||
When Docker CLI or Docker Desktop use credentials, a user prompt may pop up for the password you set during the gpg key generation.
|
||
|
||
```console
|
||
$ docker pull molly/privateimage
|
||
Using default tag: latest
|
||
latest: Pulling from molly/privateimage
|
||
3b9cc81c3203: Pull complete

||
