func ConfigureConnectionToServer ¶

func ConfigureConnectionToServer(
	ctx context.Context, client ctrl.Client,
	namespace string, server *apiv1.ExternalCluster,
) (string, string, error)

ConfigureConnectionToServer creates a connection string to the external server, using the configuration inside the cluster and dumping the secret when needed. This function will return a connection string, the name of the pgpass file to be used, and an error state

func DumpSecretKeyRefToFile ¶

func DumpSecretKeyRefToFile(
	ctx context.Context, client ctrl.Client,
	namespace string, serverName string, selector *corev1.SecretKeySelector,
) (string, error)

DumpSecretKeyRefToFile dumps a certain secret to a file inside a temporary folder using 0600 as permission bits.

This function overlaps with the Kubernetes ability to mount a secret in a pod, with the difference that we can change the attached secret without restarting the pod. We also need to have more control over when the secret content is updated.

func ReadSecretKeyRef ¶

func ReadSecretKeyRef(
	ctx context.Context, client ctrl.Client,
	namespace string, selector *corev1.SecretKeySelector,
) (string, error)
