Long, short story: CLI animation with some minor annoyances. “Handcrafted” most of em out of the .c file, followed by a bunch of gcc flags. Made it distroless, and this came up. Then my “sharing itch” started after checking the memory usage of the container at a whooping 0 bytes. (I know it must be way more than that, but still.). Just curious if I screwed something up or not. Also, c/Docker is really dead so I had to resort to you guys.
docker run -it --rm --log-driver none --net none --cap-drop=all --read-only --security-opt=no-new-privileges defnotgustavom/nyancat
Downvotes are to the left if you just don’t care and need that dopamine/self-validation hit, I guess. (Just saying since last time I shared a simple command, with code and all, and I got downvoted to oblivion plus my thread deleted for no apparent reason, so eh.)

Works great on my Raspberry Pi 4! (Most Docker images don’t support arm64.)
Glad to hear! Thanks.
My downvotes are to the right 😩, I guess this means I gotta upvote
Eh, that was meant to be a slight mockery for “ex-redditors” (since they are mostly composed of “downvote-happy” users).
I know, this comment was my silly way of saying I like what you’re doing.
Oh. Thank you then. :p
Why wrap a CLI tool in a docker container? Wouldn’t it be simpler to directly compile nyancat to multiple architectures if the goal is to make it run on all platforms?
I would imagine it’s just to experiment with docker
If you really wanted to, you could create an actually portable executable :)
That looks really interesting! Does this exist for other languages like Rust?
Yes, some people tried it, and it seems to work: ahgamut.github.io/2022/07/27/ape-rust-example/
Very interesting, might have to check that out sometime
Like go?
Because I’m doing this as a “self-learning” process. Plus, docker is an excellent tool and even “silly” images like this one can give me an edge while looking for (more) jobs, so there’s that. Coding could grant me the same “edge” as well yes, but docker has “more value” since it requires you to code -AND- to have some knowledge/depth regarding typical “dockerization” processes.
Neat! What proccess did you follow for building distroless? I was using buildah, mounting dir, yum installing into the mount, and exporting that container off.
Eh…the usual “FROM: alpine:edge”, pull everything in with git, change the code as needed, static compiling everything, strip dead code out of the binary, send the binary in a scratch image and then assigning a non-root user to it.
