How can we help you?

ImagePullSecret is a Kubernetes resource that stores credentials for accessing private container registries. It allows your cluster to pull images from private repositories like Docker Hub, GitHub Container Registry (ghcr.io), or your own private registry. Without ImagePullSecret, Kubernetes cannot authenticate to private registries and will fail to pull images, resulting in ImagePullBackOff errors.

You can create an ImagePullSecret using our web interface by clicking the "Create New ImagePullSecret" button. You'll need to provide: • Secret Name: A unique name for your secret • Registry URL: The container registry address (e.g., ghcr.io, docker.io) • Username: Your registry username • Password: Your registry password or access token

We support all major container registries including Docker Hub, GitHub Container Registry (ghcr.io), GitLab Container Registry, Amazon ECR, Google Container Registry (GCR), Azure Container Registry (ACR), and any private registry that uses standard Docker authentication.

Yes, security is our top priority. All credentials are encrypted at rest using AES-256 encryption and transmitted over TLS. We never store your passwords in plain text. Additionally, we recommend using access tokens instead of passwords whenever possible.

To update your credentials, navigate to the Secrets section, find the secret you want to update, and click the edit icon. You can then modify the registry URL, username, or password. Changes take effect immediately for new pod deployments.

ImagePullSecrets are namespace-scoped in Kubernetes, meaning they can only be used within the namespace where they are created. However, you can easily copy a secret to multiple namespaces using our duplicate feature, or create a secret with the same credentials in each namespace.
