func Open(c Config) (*sqlx.DB, error)

Open uses the provided Config to connect to a MySQL database. If the connection is opened successfully, Open will also try to ping the connection to validate it further.

Types

type Config

type Config struct {
	User       string `envconfig:"USER" required:"true" default:"root"`
	Password   string `envconfig:"PASSWD"`
	Host       string `envconfig:"HOST" required:"true" default:"localhost"`
	Port       int    `envconfig:"PORT" required:"true" default:"3306"`

}

func NewDBMux

func NewDBMux(db *sqlx.DB) *DBMux

func (*DBMux) DB

func (m *DBMux) DB() *sqlx.DB

func (*DBMux) Refresh

func (m *DBMux) Refresh(log logrus.FieldLogger, c Config, dur time.Duration)

Refresh periodically refreshes the passed DB connection, if the connection is using IAM authentication. Credentials generated this way last for 15 minutes, per AWS's documentation:

https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.IAMDBAuth.html

This function should be run as a goroutine, i.e.:

db, _ := mysql.Open(cfg) go mysql.Refresh(log, cfg, 10 * time.Minute, db)
