This document explains about how to build RDKB containerization image and use it. In addition it also has some useful commands which can be used to handle the containers
...
1) Create a *.xml file on the following path meta-cmf-raspberrypi/recipes-containers/lxc-container-generator/files/xml/*.xml
...
The code is developed and changes made in necessary files for containerization.
To download code, following commands are needed to be executed

$ repo init -u https://code.rdkcentral.com/r/manifests -m rdkb-raspberrypi.xml -b morty
$ repo sync -j4 --no-clone-bundle |

2) Include the lxc_conf_Psm<NAME>.xml file on SRC_URI of the bb file meta-cmf-raspberrypi/recipes-containers/lxc-container-generator/lxc-container-generator-native.bbappend

---|---|---|

#For example, Adding lxc_conf_Psm.xml to the recipie
SRC_URI_append = "${@bb.utils.contains('DISTRO_FEATURES', 'lxc-secure-containers-br', ' file://xml/lxc_conf_Psm.xml ', '', d)}"
do_install_append () {
${@bb.utils.contains('DISTRO_FEATURES', 'lxc-secure-containers-br', ' install_lxc_config secure lxc_conf_Psm.xml ', '', d)}
} |
3) Add the un-privileged user permission Provide user permission for the new container to run as unprivileged , in meta-cmf-raspberrypi/recipes-core/images/add-users-groups-file-owners-and-permissions-broadband.inc
...
4) Dbus socket should allow the newly created conatiner to access system bus, to do so ,we need to add the conatiner conatiner user name to system.conf

#Add sed the new user name in below line , sed -i '/allow user/c\<deny user="*"/>\n<allow user="ccspcr"/>\n<allow user="psm"/>\n<allow user="pandm"/>\n<allow user="ccspwifi"/>\n<allow user="USER_NAME"/>\n<allow user="ccsplmlite"/>\n<allow user="root"/>' ${D}/usr/share/dbus-1/system.conf |
