Node not found in alpine docker

I have the following Dockerfile:

FROM alpine:3.3

RUN apk update \
  && apk add curl tar git gzip

RUN curl --retry 3 --retry-delay 20 --show-error --location --remote-name --silent "https://nodejs.org/dist/v6.2.0/node-v6.2.0-linux-x64.tar.gz" \
  && tar -xzf "node-v6.2.0-linux-x64.tar.gz" -C /usr/local --strip-components=1 --same-owner \
  && rm -rf "node-v6.2.0-linux-x64.tar.gz" \
  && ls -la /usr/local/bin && env \
  && /usr/local/bin/node -v \
  && npm cache clear

Building the image gives me:

How is it possible for node to not be found? It's installed in the correct directory, it's in the path, and has execution permission...

There is an official and up to date node package for alpine, you don't need to install it manually, just add this line in your Dockerfile:

RUN apk add nodejs=6.2.0-r0

Or you could use an existing nodejs alpine image:

FROM mhart/alpine-node:6.2.0

On a side note, the whole point of using an alpine based image is to get rid of the clutter, installing git, tar et al. is a waste of space IMHO.
