Alpine Linuxベースのドッカーにpylintをインストールする

Question

official Python imageのAlpine Linuxディストリビューションに基づくカスタムDockerイメージにPylintをインストールしようとしています。私は、次のDockerfileで試してみました：

FROM python:3.4-alpine 
RUN apk add --update pylint 

< <を。これは、ほかに

The command '/bin/sh -c apk add --update pylint' returned a non-zero code: 1 

で失敗し、私はこれは

で失敗

最後に、私は次のようDockerfileでソースからPylintを構築しようとした：

FROM python:3.4-alpine 
RUN apk add --update openssl 
RUN wget https://github.com/PyCQA/pylint/archive/master.zip 
RUN unzip master.zip 
RUN cd pylint-master && python3 setup.py install

setuptoolsの最新バージョンのように見えませんでした。 Dockerfileに追加した後、pippylintのインストール方法は問題ありません。

FROM python:3.4-alpine 
RUN pip3 install -U setuptools 
RUN pip3 install -U pylint
