qontainer

qontainer = QEMU + Container

Run QEMU based virtual machine in a Container native way.

With Docker

# With Ubuntu (default ID/PW is deploy/deploy)
$ docker run --rm -it\
    --device=/dev/kvm:/dev/kvm --device=/dev/net/tun:/dev/net/tun\
    --cap-add NET_ADMIN \
    -e VM_CPU=2\
    -e VM_MEMORY=2G\
    -e VM_DISK="https://cloud-images.ubuntu.com/jammy/current/jammy-server-cloudimg-amd64-disk-kvm.img" \
    -e VM_DISK_SIZE=25G\
    -e NETWORK_TYPE=bridge\
    -v $PWD:/data\
    ghcr.io/iwanhae/qontainer:v1.0.0

# With Amazon Linux 2 (default ID/PW is deploy/deploy)
$ docker run --rm -it\
    --device=/dev/kvm:/dev/kvm --device=/dev/net/tun:/dev/net/tun\
    --cap-add NET_ADMIN \
    -e VM_CPU=2\
    -e VM_MEMORY=2G\
    -e VM_DISK="https://cdn.amazonlinux.com/os-images/2.0.20231101.0/kvm/amzn2-kvm-2.0.20231101.0-x86_64.xfs.gpt.qcow2" \

    -e NETWORK_TYPE=bridge\
    -v $PWD:/data\

With Kubernetes

It is even working on Kubernetes with Cilium. I believe you know what to do ¯\_(ツ)_/¯
