Застрял с довольно простым docker-compose Dockerfile проектом . Вот Dockerfile :

 FROM ubuntu:20.04

RUN apt-get update
RUN apt-get upgrade -y

#RUN apt-get install -y build-essential libssl-dev git libncurses5-dev unzip gawk zlib1g-dev flex vim curl wget bison python net-tools iputils-ping libflatbuffers-dev

RUN mkdir -p /opt/ide/

COPY . /home
WORKDIR /home

RUN tar -xf m2m-eclipse.tar.gz -C /opt/ide/
RUN ls /opt/ide/eclipse/
 

и docker-compose.yml :

 version: "2"
services:
  openwrt:
    build:
      context: .
      dockerfile: Dockerfile
    container_name: openwrt_imx6ull
    entrypoint: /bin/bash
    volumes: 
      - /home/al/docker/ide/:/opt/ide/
 

Вот как я создаю и запускаю контейнер:

 docker-compose run openwrt
 

со следующими журналами:

 $ docker-compose run openwrt

I expect to find m2m-eclipse.tar.gz content at /opt/ide but it is unfortunately empty:

 # ls /opt/ide/
#
 

if I run same tar command from container shell I get expected result:

 # tar -xf m2m-eclipse.tar.gz -C /opt/ide/
# ls /opt/ide/
eclipse
 

How can I get expected behaviour (extracting tar to the volumed folder)?
Seems there is obvious thing I missed.
