Using docker-machine, how can I build a local Dockerfile on an ec2 instance without using swarm or compose?

On my local machine, I've created an ec2 instance using docker-machine, using the following two commands:

$ docker-machine create \
       --driver amazonec2 \
       --amazonec2-open-port 8000 \
       --amazonec2-iam-instance-profile iam-user \
       default

$ eval "$(docker-machine env default)"

At this point, I'm stuck. I've navigated to a local directory where my Dockerfile is and tried running docker build . but that image gets built on my local machine. I've read the documentation, and there doesn't seem to exist anything like docker-machine build.

Am I not understanding docker-machine conceptually? Should I copy over my project code to the ec2 instance and try it that way? If so, wouldn't something like that be against the point of using docker-machine in the first place?

Solution

  • As per David Maze's comment, I was mistaken, and the docker build is actually run on the remote ec2 instance. Running $ eval "$(docker-machine env -u)" points all docker commands to a remote/virtual instance.
