Are you tired of encountering the frustrating “error storing credentials – err: exit status 1, out: gpg: skipped: No public key” error when trying to log in to your Docker account? Well, you’re not alone! This pesky issue has been driving Docker enthusiasts crazy, but fear not, dear reader, for we’ve got the solution right here.
What’s Causing the Error?
Before we dive into the solution, let’s take a step back and understand what’s causing this error. The “error storing credentials” message is usually related to the Docker CLI’s inability to store your login credentials securely using the pass utility, which relies on GPG (GNU Privacy Guard) to encrypt the credentials.
GPG and Pass: The Dynamic Duo
When you run the `docker login` command, the Docker CLI uses the `pass` utility to store your credentials securely. `Pass` relies on GPG to encrypt the credentials, which are then stored in the `~/.docker/config.json` file.
The issue arises when GPG is not properly configured or is missing the required public key. This causes the `pass` utility to fail, resulting in the “error storing credentials” error.
Solution 1: Installing GPG and Generating a Key Pair
The first step in resolving this error is to ensure you have GPG installed on your system. If you’re using a Linux or macOS system, you can install GPG using the following commands:
sudo apt-get update && sudo apt-get install gnupg
For Windows users, you can download and install GPG from the official website.
Once GPG is installed, you’ll need to generate a key pair. Open a terminal and run the following command:
gpg --full-generate-key
Follow the prompts to create a new key pair. Make sure to choose a strong password and store it safely.
Solution 2: Configuring GPG and Pass
Now that you have a key pair, it’s time to configure GPG and `pass` to work together seamlessly.
In your terminal, run the following command to set the GPG agent:
gpg-agent --daemon
Next, you’ll need to configure `pass` to use the GPG agent. Create a new file called `~/.password-store/init.gpg` with the following contents:
#!/bin/bash export GPG_TTY=$(tty) gpg-connect-agent /bye
Make the file executable by running:
chmod +x ~/.password-store/init.gpg
Finally, add the following line to your `~/.bashrc` file (or equivalent) to set the `PASS_GPG_AGENT_INFO` environment variable:
export PASS_GPG_AGENT_INFO=$(gpg-connect-agent /bye)
Reload your `~/.bashrc` file by running:
source ~/.bashrc
Solution 3: Docker Login and Credential Storage
With GPG and `pass` configured, you’re now ready to log in to your Docker account and store your credentials securely.
Run the following command to log in to your Docker account:
docker login
Enter your Docker username and password when prompted. If everything is configured correctly, you should see a success message indicating that your credentials have been stored securely.
Troubleshooting Common Issues
If you’re still encountering issues, here are some common problems and their solutions:
GPG Key Not Found
If you’re seeing an error message indicating that the GPG key was not found, try running the following command to list all available keys:
gpg --list-keys
Make sure you have a key pair generated and configured correctly.
Pass Utility Errors
If you’re experiencing issues with the `pass` utility, try reinstalling it or checking the `~/.password-store` directory for any errors.
Docker Login Errors
If you’re still encountering issues with the `docker login` command, try resetting your Docker credentials by running:
docker logout
Then, try logging in again using the `docker login` command.
Conclusion
And there you have it! With these solutions, you should be able to overcome the frustrating “error storing credentials – err: exit status 1, out: gpg: skipped: No public key” error and securely log in to your Docker account.
Remember to keep your GPG key pair and password safe, and don’t hesitate to reach out if you encounter any further issues.
