Variables

var Set = wire.NewSet(
	Open,
	rds.CertFetcherSet,
)

Set is a Wire provider set that provides a *sql.DB given *Params and an HTTP client.

Functions

func Open

func Open(ctx context.Context, provider CertPoolProvider, params *Params) (*sql.DB, func(), error)

Open opens an encrypted connection to an RDS MySQL database.

The second return value is a Wire cleanup function that calls Close on the database and ignores the error.

Types

type CertFetcher

type CertFetcher = rds.CertFetcher

CertFetcher pulls the RDS CA certificates from Amazon's servers. The zero value will fetch certificates using the default HTTP client.

type CertPoolProvider

type CertPoolProvider = rds.CertPoolProvider

A CertPoolProvider obtains a certificate pool that contains the RDS CA certificate.

type Params

type Params struct {
	// Endpoint is the host/port of the RDS database, like
	// "myinstance.borkxyzzy.us-west-1.rds.amazonaws.com:3306".
	// If no port is given, then 3306 is assumed.
	Endpoint string
	// User is the database user to connect as.
	User string
	// Password is the database user password to use.
	Password string
	// Database is the MySQL database name to connect to.
	Database string

	// TraceOpts contains options for OpenCensus.
	TraceOpts []ocsql.TraceOption
}

Params specifies how to connect to an RDS database.
