[chunfuwen]

use below command to build image with config file [root@dell-per430-17 images]# cat config.json {"blueprint": {"customizations": {"user": [{"name": "alice", "password": "bob", "groups": ["wheel", "admins"], "key": "ssh-rsa xx}

sudo podman run --rm -it --privileged --pull=newer --security-opt label=type:unconfined_t -v /var/lib/libvirt/images/output:/output -v /var/lib/libvirt/images/config.json:/config.json   -v /var/lib/containers/storage:/var/lib/containers/storage  -v /var/lib/libvirt/images/auth.json:/run/containers/0/auth.json  quay.io/centos-bootc/bootc-image-builder:latest  --type qcow2 --tls-verify=true  --config /config.json quay.io/centos-bootc/centos-bootc:stream9

and throw below error:

As per web page https://github.com/osbuild/bootc-image-builder , it give one example with group:admins

{
  "customizations": {
    "user": [
      {
        "name": "alice",
        "password": "bob",
        "key": "ssh-rsa AAA ... [email protected]",
        "groups": [
          "wheel",
          "admins"
        ]
      }
    ]
  }
