I'm trying to prototype a simple image builder using builtKit, Docker's new image builder. I'm not using the command line interface but instead using the client. There's not much documentation on how to use this thing besides the examples.
I need to run a build from a Dockerfile but the example build-using-dockerfile isn't very intuitive. Most importantly, when I run the example with build-using-dockerfile -t 'test:latest' . ('.' being the current directory which contains a simple Dockerfile) the program stalls on
[+] Building 0.0s (0/0)
And is stuck there. How can I do this build using a Dockerfile?
I guess you just followed these steps to configure and build build-using-dockerfile, you also need to configure and install buildkitd daemon.
This is what I did and it worked.
git clone https://github.com/moby/buildkitbuildkitd and buildctl as mentioned here.buildkitd daemon in background. buildkitd --debug --root /var/lib/buildkit &build-using-dockerfile as mentioned here.$ build-using-dockerfile -t testimage:v1 .
