从Node.js将dockerfile字符串插入`docker build`无法正常工作

Question

I am trying to pipe a Dockerfile to docker build via stdin as mentioned here:

https://docs.docker.com/engine/reference/commandline/build/#specify-a-dockerfile--f

I have tried everything, and Docker just doesn't seem to accept the my stdin.

const dockerfileStr = 'FROM alpine-node'
const child = spawn('docker build . -f -', {shell:true, stdio: ['pipe', 'inherit']})
child.stdin.write(dockerfileStr + '\n')
child.stdin.end()

Maybe it expects a tty ?

Answer 1

So it turns out it was just being slow because my build context was massive. And it didn't seem to report status...
