bootc-quarkus-optaplanner

A trivial podman-systemd unit that runs an instance of the Caddy webserver (just to have a service to talk to)
A quarkus application built from quarkus examples (Optaplanner) using another podman-systemd unit
Automatic updates enabled by default

Demo image

quay.io/jwesterl/bootc-quarkus-optaplanner:latest quay.io/jwesterl/bootc-quarkus-optaplanner:no-cloud-init

Built using,

podman build -f Containerfile.no-cloud-init -t quay.io/jwesterl/bootc-quarkus-optaplanner:no-cloud-init .
podman build -f Containerfile -t quay.io/jwesterl/bootc-quarkus-optaplanner:latest .
podman build --cap-add SYS_ADMIN -f Containerfile.systemd -t quay.io/jwesterl/bootc-quarkus-optaplanner:systemd

Use Image

To boot this I'll share 2 ways I've been using. I'm running Fedora 39 Silverblue on x86

First way is to use an netinstall iso and use anaconda and a kickstart file. Make sure to update the command with the correct path to your kickstart file / ISO.

virt-install --connect qemu:///system --name vm-name --memory 4096 --vcpus 2 --os-variant fedora-unknown --cdrom <path-to>/Fedora-Everything-netinst-x86_64-39-1.5.iso --video virtio --graphics spice --noautoconsole --disk size=10 --initrd-inject=<path-to>example.ks --extra-args "inst.ks=file:/example.ks" --location <path-to>/Fedora-Everything-netinst-x86_64-39-1.5.iso

In this git repo the example kickstart file installs the bootc-quarkus-optaplanner:no-cloud-init image and creates a user called jwesterl with password redhat and a public ssh key.

Second way, is by converting the container image to a qcow2 image and booting it using libvirt/kvm

Converting, using osbuild, https://github.com/osbuild/bootc-image-builder, create a config.json according to instructions then run,

sudo podman run \
    --rm \
    -it \
    --privileged \
    --pull=newer \
    --security-opt label=type:unconfined_t \
    -v $(pwd)/config.json:/config.json \
    -v $(pwd)/output:/output \
    quay.io/centos-bootc/bootc-image-builder:latest \
    --type qcow2 \
    --config /config.json \
    quay.io/jwesterl/bootc-quarkus-optaplanner:no-cloud-init

and then let's boot our image and inject some cloud-init data

virt-install --connect qemu:///system --name vm-name --memory 4096 --vcpus 2 --os-variant fedora-unknown --video virtio --graphics spice --noautoconsole --import --disk <path-to>/disk.qcow2

I've also tested running the bootc container "just as a normal container", So i added /usr/sbin/init as a CMD in the containerfile.systemd and run the container with:

podman run -ti --cap-add SYS_ADMIN --security-opt label=disable --device=/dev/fuse --rm quay.io/jwesterl/bootc-quarkus-optaplanner:systemd

It seems to work and I'm also able to "virt-install" this container image and get it to a running VM.
