Types

type CredentialProvider interface {
	GetCredentials(
		ctx context.Context,
		image string,
		args []string,
	) (*v1beta1.CredentialProviderResponse, error)
}

CredentialProvider is an interface implemented by the kubelet credential provider plugin to fetch the username/password based on the provided image name.

	// contains filtered or unexported fields
}

ExecPlugin implements the exec-based plugin for fetching credentials that is invoked by the kubelet.

NewProvider returns an instance of execPlugin that fetches credentials based on the provided plugin implementing the CredentialProvider interface.

func (*ExecPlugin) Run

func (e *ExecPlugin) Run(ctx context.Context) error

Run executes the credential provider plugin. Required information for the plugin request (in the form of v1beta1.CredentialProviderRequest) is provided via stdin from the kubelet. The CredentialProviderResponse, containing the username/password required for pulling the provided image, will be sent back to the kubelet via stdout.
