Package rdsutils is used to generate authentication tokens used to connect to a givent Amazon Relational Database Service (RDS) database.

    Before using the authentication please visit the docs here to ensure the database has the proper policies to allow for IAM token authentication.

    When building the connection string, there are two required parameters that are needed to be set on the query.

    * tls
    * allowCleartextPasswords must be set to true
    Example creating a basic auth token with the builder:
    v := url.Values{}
    v.Add("tls", "tls_profile_name")
    v.Add("allowCleartextPasswords", "true")
    b := rdsutils.NewConnectionStringBuilder(endpoint, region, user, dbname, creds)
    connectStr, err := b.WithTCPFormat().WithParams(v).Build()

    var ErrNoConnectionFormat = awserr.New("NoConnectionFormat", "No connection format was specified", nil)

      ErrNoConnectionFormat will be returned during build if no format had been specified


      func BuildAuthToken

      func BuildAuthToken(endpoint, region, dbUser string, creds *credentials.Credentials) (string, error)

        BuildAuthToken will return an authorization token used as the password for a DB connection.

        * endpoint - Endpoint consists of the port needed to connect to the DB. <host>:<port> * region - Region is the location of where the DB is * dbUser - User account within the database to sign in with * creds - Credentials to be signed with

        The following example shows how to use BuildAuthToken to create an authentication token for connecting to a MySQL database in RDS.

        authToken, err := BuildAuthToken(dbEndpoint, awsRegion, dbUser, awsCreds)
        // Create the MySQL DNS string for the DB connection
        // user:password@protocol(endpoint)/dbname?<params>
        connectStr = fmt.Sprintf("%s:%s@tcp(%s)/%s?allowCleartextPasswords=true&tls=rds",
           dbUser, authToken, dbEndpoint, dbName,
        // Use db to perform SQL operations on database
        db, err := sql.Open("mysql", connectStr)

        See for more information on using IAM database authentication with RDS.


        type ConnectionFormat

        type ConnectionFormat string

          ConnectionFormat is the type of connection that will be used to connect to the database

          const (
          	NoConnectionFormat ConnectionFormat = ""
          	TCPFormat          ConnectionFormat = "tcp"

            ConnectionFormat enums

            type ConnectionStringBuilder

            type ConnectionStringBuilder struct {
            	// contains filtered or unexported fields

              ConnectionStringBuilder is a builder that will construct a connection string with the provided parameters. params field is required to have a tls specification and allowCleartextPasswords must be set to true.

              func NewConnectionStringBuilder

              func NewConnectionStringBuilder(endpoint, region, dbUser, dbName string, creds *credentials.Credentials) ConnectionStringBuilder

                NewConnectionStringBuilder will return an ConnectionStringBuilder

                func (ConnectionStringBuilder) Build

                func (b ConnectionStringBuilder) Build() (string, error)

                  Build will return a new connection string that can be used to open a connection to the desired database.

                  b := rdsutils.NewConnectionStringBuilder(endpoint, region, user, dbname, creds)
                  connectStr, err := b.WithTCPFormat().Build()
                  if err != nil {
                  const dbType = "mysql"
                  db, err := sql.Open(dbType, connectStr)

                  func (ConnectionStringBuilder) WithDBName

                    WithDBName will return a builder with the given database name

                    func (ConnectionStringBuilder) WithEndpoint

                    func (b ConnectionStringBuilder) WithEndpoint(endpoint string) ConnectionStringBuilder

                      WithEndpoint will return a builder with the given endpoint

                      func (ConnectionStringBuilder) WithFormat

                        WithFormat will return a builder with the given connection format

                        func (ConnectionStringBuilder) WithParams

                          WithParams will return a builder with the given params. The parameters will be included in the connection query string

                          v := url.Values{}
                          v.Add("tls", "rds")
                          b := rdsutils.NewConnectionBuilder(endpoint, region, user, dbname, creds)
                          connectStr, err := b.WithParams(v).WithTCPFormat().Build()
