go service exits with code 0 immidiately

[hazy stone]

Hello everyone, I have a problem with my service. It exits with code: 0 but when I manually start the service it is all fine. What do you think could be the problem here?

I have tried using tty: true and stdin_open: true but none of them worked.

Dockerfile

FROM golang:1.16-alpine

ADD . /go/src/user-service
WORKDIR /go/src/user-service

RUN go build -o /user-service

EXPOSE 8080

ENTRYPOINT [ "/user-service" ]

docker-compose.yml

version: '3.3'

services:

  database:
    image: mongo
    ports:
      - "27017:27017"
    healthcheck:
      test: mongo --norc --quiet --host=localhost:27017 --eval "db.getMongo()"
      interval: 30s
      timeout: 2s
      retries: 3
      start_period: 15s

  user:
    build: .
    ports:
      - "8080:8080"
    depends_on:
      database:
        condition: service_healthy

what is your code doing

[hazy stone]

are you sure that is relevant? it just creates an http server

[astral raft]

can you try running it manually and see if that also exits

[hazy stone]

when I only start the Dockerfile(not docker-compose.yml), it works just fine and does not exist.

how does the connection to mongo look like

[hazy stone]

func InitDatabase(databaseUri string) *mongo.Database {
    client, err := mongo.Connect(context.TODO(), options.Client().ApplyURI(databaseUri))
    if err != nil {
        log.Println(err)
        panic(err)
    }

    err = client.Ping(context.TODO(), readpref.Primary())
    if err != nil {
        log.Println(err)
        panic(err)
    }

    database := client.Database(DatabaseName)

    return database
}

whats ur databaseuri

[hazy stone]

this is my main

func main() {
    router := gin.Default()

    validator := validator.New()
    database := repository.InitDatabase("mongodb://database:27017")
    userRepository := repository.NewUserRepository(database)
    userService := service.NewUserService(userRepository)
    userController := controller.NewUserController(userService, validator)

    router.GET("/users", userController.GetUsers)
    router.GET("/users/:id", userController.GetById)
    router.POST("/users", userController.Create)
    router.PATCH("/users/:id", userController.UpdateById)
    router.DELETE("/users/:id", userController.DeleteById)

    router.Run()
}```

[tight bolt]

that looks fine

no other logs than the exist code?

[hazy stone]

no, could it be the reason that service doesn't wait for database?

[tight bolt]

database is up 15 seconds BEFORE service is

that shouldnt be an issue

unless your db is fucked up

[hazy stone]

can I screen share for a second? @tight bolt

[tight bolt]

no

im playing league

[ruby glade]

It would not exit with 0 as you panic

[warm fjord]

Doesn’t router Run return an error?

Might want to check that one

[hazy stone]

I changed docker-compose to this and it worked

version: '3.8'

services:

  database:
    image: mongo
    container_name: mongo-db
    ports:
      - "27017:27017"

  user:
    container_name: user-api
    build: .
    ports:
      - "8080:8080"
    depends_on:
      - database

[warm fjord]

My bet is still on ignored errors

[marsh basin]

non-blocking main goroutine

db connection fails, app dies

[warm fjord]

Also a good guess
