[limber reef]

Hello

i start to get this Error:
/app/api/database/connect.go:28 +0x15b
main.main()
/app/main.go:73 +0x4a
panic: dial tcp: lookup containers-us-west-181.railway.app: i/o timeout

somtimes is stop after 1 min somtimes is take 5 min

here is the conntion:

func InitRedis() (*redis.Storage, error) {
port, err := strconv.Atoi(os.Getenv("REDISPORT"))
if err != nil {
port = 6379
}
storage := redis.New(redis.Config{
Host: os.Getenv("REDISHOST"),
Port: port,
Username: os.Getenv("REDISUSER"),
Password: os.Getenv("REDISPASSWORD"),
Database: 0,
Reset: false,
TLSConfig: nil,
PoolSize: 10 * runtime.GOMAXPROCS(0),
})
return storage, nil
}

i have add the log file

add a time.Sleep(3 * time.Second) right before the redis.New line

[limber reef]

okay i will try that on the next deploy

[wind sandal]

I also would really not recommend trying to dynamically compute the pool size, or anything that relies on determining the cpu count while on Railway because go will detect the 32 cores of the host machine and throw your code out of wack for lack of a better word

[limber reef]

okay is they a good number to set it at?

[wind sandal]

you're on hobby, so you have 8 vcpus, set the pool variable at a static 80

[limber reef]

this is the default PoolSize: 10 * runtime.GOMAXPROCS(0),

[wind sandal]

by using that go max procs function and setting it to zero, you are telling go to use 0 cpus, this would have unintended consequences down the line

okay i just show this var ConfigDefault = Config{
Host: "127.0.0.1",
Port: 6379,
Username: "",
Password: "",
URL: "",
Database: 0,
Reset: false,
TLSConfig: nil,
PoolSize: 10 * runtime.GOMAXPROCS(0),
Addrs: []string{},
MasterName: "",
ClientName: "",
SentinelUsername: "",
SentinelPassword: "",
}

what redis package are you using?

github.com/gofiber/storage/redis/v3

[wind sandal]

set it to 80

[limber reef]

okay thx i will do that

just to be clear you mean like PoolSize: 80,

[wind sandal]

yes
