Join Arthur Ulfeldt for an in-depth discussion in this video Building Dockerfiles, part of Learning Docker.
- [Instructor] Now, let's build a Dockerfile.…Let's start with the most basic Dockerfile…that's still at all interesting.…Make a file called Dockerfile, with a capital D,…and I'm gonna put this in it,…and then I'm gonna build it and run it.…Let's go take a look.…So first, let me make a spot…to put our examples, mkdir example.…Alright, now let's go into that folder, ls.…Nothing there.…
I'm gonna use a simple text editor, nano Dockerfile.…Alright, the first line in a Dockerfile…specifies what image to start with.…Where do we begin?…That's FROM, and I'm gonna start…from an image called busybox.…It's very small and it has nothing but a shell in it.…Super tiny.…And starting from busybox, I would like to RUN,…so create a container in that container, RUN echo,…building simple docker image.…
Okay, after that's run, it's gonna save it into an image,…and then from that image, it's going to set…CMD to run when this image is started.…So, when this image is started,…I'm gonna have it run echo,…hello container.…So now I'm gonna exit, Control + X.…
