title: Can I remove `RUN apk add --no-cache python2 g++ make` from my Dockerfile?
body: <p>In the <a href="https://docs.docker.com/get-started/02_our_app/" rel="nofollow noreferrer">docker tutorial</a> I'm following it tells me to put the following commands in my <code>Dockerfile</code>:</p>
  <pre><code># syntax=docker/dockerfile:1
  FROM node:12-alpine
  RUN apk add --no-cache python2 g++ make
  WORKDIR /app
  COPY . .
  RUN yarn install --production
  CMD [&quot;node&quot;, &quot;src/index.js&quot;]
  </code></pre>
  <p>I understand what all of the lines are doing, except for:</p>
  <pre><code>RUN apk add --no-cache python2 g++ make
  </code></pre>
  <p>And everything seems to work without it. Can I delete this line from my <code>Dockerfile</code>? Will deleting this line cause problems for me down the road? Why do I need anything &quot;python&quot; in this node project?</p>
