I have docker container with H2 database, I can connect to it using “Database” IDE feature, also can ping container host using DNS name inside my server container.

I’m using github.com/jmrobles/h2go package as database driver, so i tried (i deleted some unnessecary code):

package service

import (
    _ "github.com/jmrobles/h2go"
)

func (s *DataSourceService) ConnectToH2Db(dbHost, dbUsername, dbPassword, dbName string, dbPort int) (*sqlx.DB, error) {
    connectionData := fmt.Sprintf("h2://%v:%v@%v:%v/%v", dbUsername, dbPassword, dbHost, dbPort, dbName)
    logrus.Info(connectionData)
    conn, err := sqlx.Open("h2", connectionData)
    if err != nil {
        logrus.Info("open")
        return nil, err
    }
    if err = conn.Ping(); err != nil {
        logrus.Info("ping")
        return nil, err
    }
    return conn, nil
}

When trying to connect i got driver: bad connection and logrus printed open.

Thanks in advance for the answer.
