Understanding Argo CD
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. It allows developers to manage and deploy applications to Kubernetes clusters using Git repositories as the source of truth. By continuously monitoring Git repositories, Argo CD ensures that the state of the applications in the cluster matches the desired state defined in the repository.
Identifying the Symptom
One common issue users encounter is the 'Argo CD repository authentication error'. This error typically manifests when Argo CD is unable to authenticate with the Git repository, preventing it from accessing the necessary files to deploy applications.
Common Error Messages
When this issue occurs, you might see error messages such as:

Exploring the Issue
The root cause of this problem is usually related to incorrect or outdated credentials configured in Argo CD. This can happen if the credentials have expired, been revoked, or were never correctly set up in the first place.
Potential Causes
- Incorrect username or password.
- Expired or invalid SSH keys.
- Misconfigured repository URL.
Steps to Resolve the Authentication Error
To resolve the repository authentication error, follow these steps:
Step 1: Verify Repository Credentials
Ensure that the credentials used by Argo CD to access the repository are correct. This includes:
- Checking the username and password for HTTP/HTTPS access.
- Verifying SSH keys for SSH access.
For more information on setting up repository credentials, refer to the Argo CD documentation.
Step 2: Update Credentials in Argo CD
If the credentials are incorrect, update them using the Argo CD CLI or UI:
argocd repo add --username --password
For SSH access, ensure that the SSH key is correctly configured:
argocd repo add --ssh-private-key-path
Step 3: Test the Connection
After updating the credentials, test the connection to ensure that Argo CD can access the repository:
argocd repo list
Check the status of the repository to confirm that it is now accessible.
