Simplistic container runtime shim

shimmy - container runtime shim

Shimmy is a simplistic shim between container manager and container runtime. It's primary designed to make programmatic runc execution more friendly for the launching process. It does a couple of handy things:

• Detaches container runtime process from the launching process.
• Forwards container STDOUT and STDERR to logs.
• Tracks container termination and writes its status on disk.
• [TODO] Allows attaching to container STDIN to forward some data in.
• [TODO] Allows attaching to container STDOUT & STDERR to read some data from.
• [TODO] PTY-driven attaching.

Usage

shimmy's Issues

Simple container manager / shim for runc / crun

Hi,

I play with a custom linuxkit build based on crun runtime, but it needs a container manager to check health and (optional) restart if process is killed.

Searched for conman / shim topics and found shimmy. Is there such a project or would it possible to use shimmy for that?

rust implementation memory cost friendly

have you plan to implement completely shimv2 ？
