• Use osbuilder to create a custom rootfs.
• Ensure you add extra packages for bash, strace, gdb (and maybe rust-gdb).
• Install an updated kata-agent.service file into the image:

  $ cat kata-agent.service.in

Background

Chelsea and I have been looking at adding end-to-end openTelemetry tracing support to Kata Containers.

Components

With Kata 2.x's simpler architecture, we only need tracing support in:

• hypervisor (ideally)

jodh-intel

Full fat kernel

Background

• Originally, the guest kernel was as minimal as possible.
• Booted extremely fast, but didn't support all uses-cases.
• Over time, we have added lots of extra kernel CONFIG_* options...
  • For new kernel options
  • For new hardware features

Why write unit tests?

• Catch regressions

jodh-intel

Install rust

• https://rustup.rs

Install the rust language server and clippy tools:

$ rustup component add rustfmt rls
$ rustup component add clippy
