No such file or directory after building the image

Docker
#1

I build the image using

docker build -t simpletelegramchatbot DockerTelegramChatBot/

and run it with

docker run -p 4000:80 simpletelegramchatbot

It isn’t able to find this directory “DockerTelegramChatBot/” that includes the docker file. so make sure you specify the correct path or move to the directory that includes the docker file and try to run this command docker build -t simpletelegramchatbot .
