I just started docker-compose after a while and am having issues I don't understand. I want to install net-tools on the container, but it does not seem to work like it used to.

my Dockerfile looks like this: file1

FROM logstash:7.4.2
MAINTAINER 
# RUN  npm install -g bower && npm install --global gulp-cli

RUN uname -a
# RUN apt-get update && apt-get install -y bash
# RUN apt-get update 
RUN apk add net-tools

file 2:

FROM elasticsearch:7.4.2
MAINTAINER 
# RUN  npm install -g bower && npm install --global gulp-cli

# RUN  apt-get update -y && apt-get upgrade -y
# RUN apk update
# RUN apk add --update net-tools
# RUN apk-install add 
RUN uname -a
EXPOSE 9200

docker-compose file looks like this:

version: '2'

services:
    logstash:
        build: ../images/logstash
        links: ["elasticsearch"]

    elasticsearch:
        build: ../images/elasticsearch
        ports:
            - "9200:9200"

When I run I get this:

I have tried apt-get but is not working.

How am I supposed to install packages on compose?
