Environment:MacOS Docker Server: 19.03.5
Go: 1.13
I was able to connect to Atlas with Single stage docker build. However, when I want to optimise the image, i go for multi stage docker build, it cannot connect to Atlas, without any change on code
Go code
url := "mongodb+srv://<USERNAME>:<PASSWORD>@cluster0-7odzu.mongodb.net/test?retryWrites=true&w=majority" client, err := mongo.NewClient(options.Client().ApplyURI(url)) log.Println("db client created") if err != nil { log.Fatal(err) } ctx, cancel := context.WithTimeout(context.Background(), 20*time.Second) defer cancel() err = client.Connect(ctx) if err != nil { return nil, err } log.Println("db client connected") err = client.Ping(ctx, readpref.Primary()) if err != nil { return nil, err } log.Println("db client ping")

Current console output

Expected console output (when using single stage docker build)
