![]() From the configuration file itself: These variables represent groupings of functionality in the CNCF landscape. In particular, they are areas where there is a choice between more than one implementation or an area where abstraction is beneficial. The contents of the variables are are runtime components that recipes may use for RDEPENDS. Build dependencies are not typically flexible, so do not currently have DEPENDS equivalents for the components (i.e. DEPENDS on runc versus crun). Distro features such as kubernetes or other container stacks can be used to set different defaults for these variables. Note: these are "global" values, since they represent choices. If more than of a grouping is required on target, then the variable can be appended or set to multiple values. That being said, Recipes should generally agree on the values, hence the global namespace. Recipe specific choices can still be done, but they risk conflicting on target or causing runtime issues / errors. ## CNCF "components" # engines: docker-ce/docker-moby, virtual-containerd, cri-o, podman VIRTUAL-RUNTIME_container_engine ??= "podman" # runtime: runc, crun, runv, runx VIRTUAL-RUNTIME_container_runtime ??= "virtual-runc" # networking: cni, netavark VIRTUAL-RUNTIME_container_networking ??= "cni" # dns: cni, aardvark-dns VIRTUAL-RUNTIME_container_dns ??= "cni" # orchestration: k8s, k3s VIRTUAL-RUNTIME_container_orchestration ??= "k3s" ## Kubernetes terminology "components" VIRTUAL-RUNTIME_cri ??= "containerd" VIRTUAL-RUNTIME_cni ??= "cni" Signed-off-by: Bruce Ashfield <bruce.ashfield@gmail.com> |

meta-virtualization
This layer provides support for building Xen, KVM, Libvirt, and associated packages necessary for constructing OE-based virtualized solutions.
The bbappend files for some recipes (e.g. linux-yocto) in this layer need to have 'virtualization' in DISTRO_FEATURES to have effect. To enable them, add in configuration file the following line.
DISTRO_FEATURES:append = " virtualization"
If meta-virtualization is included, but virtualization is not enabled as a distro feature a warning is printed at parse time:
You have included the meta-virtualization layer, but
'virtualization' has not been enabled in your DISTRO_FEATURES. Some bbappend files
may not take effect. See the meta-virtualization README for details on enabling
virtualization support.
If you know what you are doing, this warning can be disabled by setting the following variable in your configuration:
SKIP_META_VIRT_SANITY_CHECK = 1
Depending on your use case, there are other distro features in meta-virtualization that may also be enabled:
- xen: enables xen functionality in various packages (kernel, libvirt, etc)
- kvm: enables KVM configurations in the kernel and autoloads modules
- k8s: enables kubernets configurations in the kernel, tools and configuration
- aufs: enables aufs support in docker and linux-yocto
- x11: enable xen and libvirt functionality related to x11
- selinux: enables functionality in libvirt and lxc
- systemd: enable systemd services and unit files (for recipes for support)
- sysvinit: enable sysvinit scripts (for recipes with support)
- seccomp: enable seccomp support for packages that have the capability.
