This layer enables the clear containers runtime (cc-oci-runtime) for Docker:
Details about the Clear Containers project can be found at:
https://github.com/01org/cc-oci-runtime
https://clearlinux.org/features/intel%C2%AE-clear-containers
Dependencies
============
This layer depends on:
URL: git://git.yoctoproject.org/poky.git
layers: meta meta-poky meta-yocto-bsp
branch: pyro
URL: git://git.openembedded.org/meta-openembedded
layers: meta-oe meta-python meta-networking meta-filesystems
branch: pyro
URI: git://git.yoctoproject.org/meta-virtualization
branch: master
Patches
=======
Please submit any patches for meta-intel-clear-containers layer to the
meta-intel mailing list (meta-intel@yoctoproject.org):

I. Adding the meta-intel-clear-containers layer to your build
=================================================
The clear containers runtime can be added to your images with the cc-oci-runtime recipe.
Example (add to conf/local.conf):
IMAGE_INSTALL_append += " cc-oci-runtime "
In order to use this layer, you need to make the build system aware of
it.
Assuming the meta-intel-clear-containers layer exists at the top-level of your
yocto build tree, you can add it to the build system by adding the
location of the meta-intel-clear-containers layer to bblayers.conf, along with any
other layers needed. e.g.:
BBLAYERS ?= " \
/path/to/yocto/meta \
/path/to/yocto/meta-poky \
/path/to/yocto/meta-yocto-bsp \
/path/to/yocto/meta-openembedded/meta-oe \
/path/to/yocto/meta-openembedded/meta-python \
/path/to/yocto/meta-openembedded/meta-networking \
/path/to/yocto/meta-openembedded/meta-filesystems \
/path/to/yocto/meta-virtualization \
/path/to/yocto/meta-intel-clear-containers \
"
II. Misc
========
* Clear Containers depends on the following kernel module.
It will be automatically enabled for 3.9.* and 3.10.* kernels
CONFIG_VHOST_NET=m
* To modify the amount of memory available to QEMU. Add the following variable to your conf/local.conf
QEMU_CC_MEM = "2G,slots=2,maxmem=2G"
* When building docker with clear containers support, the default docker runtime will be set to cor (cc-oci-runtime). To change the default docker runtime, please modify the docker.service file and restart docker.
Example for runc (docker.service):
ExecStart=/usr/bin/dockerd -D --add-runtime cor=/usr/bin/cc-oci-runtime.sh --default-runtime=runc -H fd://
