# Meta-embedded-containers layer
## Non-maintenance notice
This layer was provided as proof-of-concept code to support a series
of articles and a talk given in 2020, and is not actively maintained.

## Description
The meta-embedded-containers provides two approaches to embed Docker
container(s) into a target root filesystem with Yocto.
The first approach is to embed a Docker archive in the root filesystem.
The second approach is to populate the Docker store (i.e.
/var/lib/docker directory) into the target root filesystem.

## Adding the meta-embedded-container layer to your build
Please run the following command:
$ bitbake-layers add-layer meta-embedded-containers
## Documentation
)
Three blog papers discuss about embedding a container image(s) inside
Yocto root filesystem.

## Customize your image recipe
The image recipe is located under
`recipes-core/images/embedded-container-image.bb` file. In the
IMAGE_INSTALL Bitbake variable, you can customize which kind of approach
you want:
- container-image: pull the container image(s) and install the Docker
store in the target root filesystem,
- container-archive: pull the container image(s) and save the container
archive(s) in the rootfs,
- container-multiple-archives: pull the container image(s), save them in
the rootfs as archive files and start them with docker-compose at
boot.
