Github explore underrated ! As i browse around github explore my interest catch on a project called youki. When i pretty confused, a different container runtime?

it’s software that runs and manages the components required to run containers.
These tools make it easier to securely execute and efficiently deploy containers, and are a key component of container management.
As containers themselves have evolved and changed, so have their runtimes.

Furthermore,

CLI tool for spawning and running containers on Linux according to the OCI specification.

So i browse around and getting to know that our current docker installation generally use runc. Then, what is the correlation with youki and the other one i found later crun, both of it also like runc but on different programming language side. Docker and it tools mostly use GO as their preferred language, also apply to runc, youki use Rust, and crun use C. How it goes? crun is the one that likely most compatible as technically it developed by RedHat for their Podman, on other hand youki on category usable with still many improvement to come, many of container will get CoreCLR crash or just throw libc err. If you also interested to try, here is how.

1. youki, generally this is build from source thing, if you familiar with rust application build then you good to go.
2. crun, binary download given on github release page.
3. Copy the youki / crun binary to general respected folder /usr/local/bin/ is my way to go.
4. Modify docker config json, /etc/docker/daemon.json

   "default-runtime": "runc",
   "runtimes": {
   "crun": {
     "path": "/usr/local/bin/crun"
   },
   "youki": {
     "path": "/usr/local/bin/youki"
   }
   },

5. Restart the docker daemon.
6. Using runtime via docker compose file, add runtime: youki or runtime: crun

   runtime: youki

7. Using docker run

   docker run --runtime youki/crun ....

   When crun claim that it half faster, in the end i can't really tell if using crun really faster than runc, it about milisecs differences. Youkai also claim in middle ground of runc and crun. But again as it miliseconds test, that really not perceptible but normal user like me.

   sources:

   • youki
   • crun
   • runc
   • container-runtime i read this 3 years late
   • RedHat crun
