The `--log-level` option when running the agent sub-command for vminitd was being silently ignored cause of the way the agent is being run. As a workaround we need to read `/proc/self/cmdline` to get the right args
Container Example
Very basic example of launching a Linux container using Containerization.
Build and Run
1. Fetch Kernel
In your terminal, change directories to examples/ctr-example and run:
Option A: Using Makefile (recommended)
make fetch-default-kernel
Option B: Copy from installed container tool
cp "$(ls -t ~/Library/Application\ Support/com.apple.container/kernels/vmlinux-* | head -1)" ./vmlinux
You should now see the vmlinux image in examples/ctr-example
2. Build/Run ctr-example
From examples/ctr-example run:
make all
Warning
If you get the following error, try building from the default macOS terminal:
error: compiled module was created by a newer version of the compiler
After the build completes, the example will run. In your terminal you should see something like:
Starting container example...
Fetching container initial filesystem...
Creating container from docker.io/library/alpine:3.16...
Starting container...
/ #
Warning
If you get the following error, try moving the
ctr-examplebinary to/var/tmpand run it from there.Swift/ErrorType.swift:254: Fatal error: Error raised at top level: unsupported: "failed to create vmnet network with status vmnet_return_t(rawValue: 1001)"
Congratulations, you've started the example container!
