Cannot connect with golang using grpc client

EventStoreDB
1

I try to create a simple golang client to connect to eventstoredb but it fails to connect.

Eventstoredb is started with docker :
docker run --name eventstore-node -it -p 2113:2113 -p 1113:1113 -e EVENTSTORE_RUN_PROJECTIONS=All -e EVENTSTORE_START_STANDARD_PROJECTIONS=true eventstore/eventstore --insecure --enable-atom-pub-over-http

I am using the EventStore-Client-Go library (https://github.com/EventStore/EventStore-Client-Go)

The source code to connect is this :slight_smile:
package main

import (
	"context"
	"fmt"
	"log"

	"github.com/EventStore/EventStore-Client-Go/client"
	"github.com/EventStore/EventStore-Client-Go/direction"
	"github.com/EventStore/EventStore-Client-Go/position"
)

func main() {
	ctx := context.Background()
	connString := "esdb://127.0.0.1:1113"
	conf, err := client.ParseConnectionString(connString)
	if err != nil {
		log.Fatal(err)
	}
	conf.DisableTLS = true
	conf.SkipCertificateVerification = true

	cli, err := client.NewClient(conf)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("%+v\n", conf)

	if cli == nil {
		log.Fatal("CLI IS NIL")
	}

	err = cli.Connect()
	if err != nil {
		log.Fatal(err)
	}

	messages, err := cli.ReadAllEvents(ctx, direction.Forwards, position.StartPosition, 1, true)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println(messages)
}

When I execute the program, I have the following error:

&{Address:127.0.0.1:1113 GossipSeeds:[] DisableTLS:true NodePreference: Username: Password: SkipCertificateVerification:true Connected:false MaxDiscoverAttempts:10 DiscoveryInterval:100 GossipTimeout:5 DnsDiscover:false}
2020/11/01 11:20:21 Failed to construct read client. Reason: rpc error: code = Unavailable desc = connection closed

Does anyone have an idea of the problem ?

Hey,

I’ve got a suspicion that it’s because you are trying to combine environment variables with passing in arguments. Try removing --insecure --enable-atom-pub-over-http and instead adding in -e EVENTSTORE_INSECURE=true -e EVENTSTORE_ENABLE_ATOM_PUB_OVER_HTTP=true.

So

docker run --name eventstore-node -it -p 2113:2113 -p 1113:1113 -e EVENTSTORE_RUN_PROJECTIONS=All -e EVENTSTORE_START_STANDARD_PROJECTIONS=true -e EVENTSTORE_INSECURE=true -e EVENTSTORE_ENABLE_ATOM_PUB_OVER_HTTP=true eventstore/eventstore
