DESCRIPTION = "A configurable container host image"
|
|
LICENSE = "MIT"
|
|
|
|
# This image is a reference implementation to create a target platform
|
|
# capable of running containers. This includes kernel configuration,
|
|
# container runtimes, tools and other support applications.
|
|
#
|
|
# The wpackages to install are largely described in the packagegroups
|
|
# that are part of this layer. packagegroups are preferred as they can
|
|
# easily be used to create similar images of different composition.
|
|
# The recipes for the packages have their list of build and runtime
|
|
# dependencies, as such, those dependencies are not part of the image
|
|
# install or listed explicitly in the packgroups.
|
|
#
|
|
# CNCF areas that have choices are described by VIRTUAL-RUNTIME
|
|
# variables. These variables can be set individually (in a distro,
|
|
# layer or local configuration file), or can be set by the setting of
|
|
# a "CONTAINER_PROFILE". It is possible to select incompatible
|
|
# packages if setting the VIRTUAL-RUNTIME variables individually.
|
|
# container profiles have been created as valid / tested stacks of the
|
|
# components in meta-virtualization.
|
|
#
|
|
# The contents of the image are selected by testing the VIRTUAL-RUNTIME
|
|
# values and mapping them to packagegroups.
|
|
#
|
|
# The possible VIRTUAL-RUNTIME variables (and their values) are
|
|
# currently:
|
|
#
|
|
## engines: docker/docker-moby, virtual-containerd, cri-o, podman, lxc
|
|
## 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 ??= "virtual-containerd"
|
|
## VIRTUAL-RUNTIME_cni ??= "cni"
|
|
#
|
|
# To select a CONTAINER_PROFILE, set the variable in your local,
|
|
# distro or layer configuration:
|
|
#
|
|
# CONTAINER_PROFILE="<your value>"
|
|
#
|
|
# The possible values for CONTAINER_PROFILE can be found in
|
|
# conf/distro/include in the format of: meta-virt-container-<profile>.inc
|
|
