我有以下 Dockerfile：
FROM alpine:latest
COPY . .
# C-CPP
RUN apk update \
&& apk add build-base \
&& apk add g++
# JAVA 8
RUN apk fetch openjdk8 \
&& apk add openjdk8
ENV JAVA_HOME=/usr/lib/jvm/java-1.8-openjdk
ENV PATH="$JAVA_HOME/bin:${PATH}"
# Python 3
RUN apk add python3 py3-pip \
&& apk add --upgrade bash
RUN ["chmod", "+x", "./run.sh"]
ENTRYPOINT [ "./run.sh" ]
当我点击 command 时docker build -t dockerfile .，我收到此错误 - 这是什么意思以及如何修复它？
