我正在尝试构建一个精益的高山docker容器,以便在Google Cloud Build中对Lua进行单元测试。
它运行良好,但大约需要30到50秒来构建。当我运行失败并进行luacheck时,每个过程只需要几秒钟。关于如何优化此构建过程的任何想法?
我正在使用wget,然后切换到git。我添加了curl和unzip,因为luarocks期望它和luacheck的依赖项之一的openssl。我可以/应该使用其他依赖项吗?
FROM alpine
ENV LUA_VERSION 5.1
RUN apk update
RUN apk add lua${LUA_VERSION}
RUN apk add lua${LUA_VERSION}-dev
RUN apk add bash build-base curl git openssl unzip
RUN cd /tmp && \
git clone https://github.com/keplerproject/luarocks.git && \
cd luarocks && \
sh ./configure && \
make build install && \
cd && \
rm -rf /tmp/luarocks
RUN luarocks install busted
RUN luarocks install luacheck
RUN luarocks install luacov

您不必构建 luarocks。您可以使用安装包,
RUN apk add luarocks
