我想向nodejs高山碼頭圖像添加http_proxy環境變量。運行在nodejs上導出不接受高山碼頭圖像
docker build -t myimage:latest .
時
的Dockerfile看起來像這樣
FROM node:6-alpine
RUN export
RUN export https_proxy='http://myproxy:8080'
RUN export http_proxy='http://myproxy:8080'
RUN export
輸出看起來像這樣

正如你可以看到外殼上的出口不這樣做！
當我在新構建的圖像中打開一個shell並手動執行命令時，它可以工作。
> docker run myimage:latest sh
/# export https_proxy='http://myproxy:8080'
/# export http_proxy='http://myproxy:8080'
/# export
export HOME='/root'
export HOSTNAME='a759e3d30481'
export NODE_VERSION='6.9.5'
export NPM_CONFIG_LOGLEVEL='info'
export PATH='/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'
export PWD='/'
export SHLVL='1'
export TERM='xterm'
export http_proxy='http://myproxy:8080'
export https_proxy='http://myproxy:8080'
那麼我做錯了什麼？
