Here 2 services in docker-compose.yml:
logger-service:
...
# Here main service using Redis by Redigo
redis:
image: redis:alpine
ports:
- "6380:6379"
environment:
REDIS_PASSWORD: password
volumes:
- ./db_data/redis:/data
restart: unless-stopped
Logger service trying to connect to Redis instance by the following func:
func connectToRedis() (redis.Conn, error) {
conn, err := redis.Dial("tcp", "redis:6379",
redis.DialPassword("password"),
)
if err != nil {
log.Println("Error connecting Redis: ", err)
return nil, err
}
_, err = redis.String(conn.Do("PING"))
if err != nil {
log.Println("Redis not pinged:", err)
return nil, err
}
log.Println("Connected to Redis")
return conn, nil
}
Logger service docker log contains panic:

main.go:27 here is just a call of connectToRedis.
Why my password provided by DialPassword is simply ignored, as far as I see in panic log?
P.S. When I comments out DialPassword, connect ends successfully, but it also means that my password ignored and Redis remains completely unsecured
Thanks to @Peter - REDIS_PASSWORD in docker environment is non-standard, so Redis service during installation just ignores it. Later I will write command tag in Redis service turning on authentication
