...

execute the following command:

$ source meta-cmf-raspberrypi/setup-environment

...

A list is obtained, select the following option from among the list:

12) meta-cmf-raspberrypi/conf/machine/raspberrypi-rdk-broadband-lxc.conf

The path is automatically directed to:

...

Use the following command to compile the complete code:

$ bitbake rdk-generic-broadband-lxc-image

To compile a specific component container use the below command:

$ bitbake <component> -c compile -f

Ex:

$ bitbake ccsp-dmcli -c compile -f

The above command will compile the dmcli component container.

...

Once the code generation for containerization is compiled, the image for the same is found under the path:

$ cd <workspace>/build-raspberrypi-rdk-broadband-lxc/tmp/deploy/images/raspberrypi-rdk-broadband-lxc/

The image to be considered:

<ImageName.rootfs.rpi-sdimg>

Ex:

Path:

$ cd container-work/build-raspberrypi-rdk-broadband-lxc/tmp/deploy/images/

Image:

raspberrypi-rdk-broadband-lxcrdk-generic-broadband-lxc-image_default_20190327101556.rootfs.rpi-sdimg

...

Generated image has to be flashed to an SD card using this command in local PC:

$ sudo dd if=<path to ImageName.rootfs.rpi-sdimg> of=<path to SD card space> bs=4M

Ex:

$ sudo dd if=rdkb-generic-broadband-image_default_20181026100202.rootfs.rpi-sdimg of=/dev/sdd bs=4M

The SD card is inserted to the Raspberry Pi board and booted to check for containers created.

...

The above folders will be created automatically based on the xml files written in the workspace.

Path :

<workspace>/meta-cmf-raspberrypi/recipes-containers/lxc-container-generator/files/xml/<container.xml>

Ex:

container-work/meta-cmf-raspberrypi/recipes-containers/lxc-container-generator/files/xml/lxc_conf_CcspPandMSsp.xml

The above xml file is written for “P and M” container and will be responsible for the generation of the 3 folders mentioned above.

2.Check all the processes running in regard to lxc.

         ps

$ ps -Af | grep lxc

The Pi terminal should show logssimilar to the following:

...

After checking pandm container status which has to be up and running, run the following commands

• Code Block
  language bash
  $ sh /lib/rdk/wifi_container.sh

  - this command may return error which can be ignored

• Code Block
  language bash
  $ sh /container/CCSPWIFI/launcher/CcspWifiSsp.sh start

Please wait for few seconds/mins till log "Enter WiFi Loop" is observed in the console

• Code Block
  language bash
  $ lxc-attach -n CCSPWIFI -f /container/CCSPWIFI/conf/lxc.conf

After execution of above command shell will change to ccspwifi
Inside container shell please run following command 

• Code Block
  language bash
  $ hostapd -B /nvram/hostapd0.conf

Now Check (in host shell) if CCSPWIFI container is running with corresponding name 

Now, can able to connect wifi client(Laptop or mobile) using default ssid: RPI3_RDKB-AP0 and password as : rdk@1234

Invoking containers manually in Raspberry Pi terminal

...

1. Run respective container scripts to execute individual container when container fails in boot up process:sh /container/<Container Name>/launcher/<container.sh> start

sh /container/<Container Name>/launcher/<container.sh> start

Ex:

$ sh /container/PSMSSP/launcher/PsmSsp.sh start

The above command can be executed to run PSM container and see its logs in Console.

...

2. Run command/commands inside the container specified by the Name when the container is already running:

$ lxc-attach -n CCSPWIFI -f /container/CCSPWIFI/conf/lxc.conf

Ex:

$ lxc-attach -n CCSPWIFI -f /container/CCSPWIFI/conf/lxc.conf

The above command can be executed to run the commands specified by lxc.conf file.

...

This command is used to quickly launch a container in an isolated environment. It mainly runs the specified command into the container via intermediate process lxc-init (forwards the received signal to starting command). Lxc-execute uses the configurations specified by the lxc-create process.

Ex:

$ lxc-execute -n DBUS -f /container/DBUS/conf/lxc.conf

...

$ lxc-execute -n PSMSSP -f /container/PSMSSP/conf/lxc.conf

...

$ lxc-execute -n CCSPPANDM -f /container/CCSPPANDM/conf/lxc.conf

...

$ lxc-execute -n CCSPWIFI -f /container/CCSPWIFI/conf/lxc.conf

...

$ lxc-execute -n CCSPCR -f /container/CCSPCR/conf/lxc.conf

lxc-attach

This command attaches to the container namespace and run a specified command inside, the already executing container.

Ex:

$ lxc-attach -n DBUS -f /container/DBUS/conf/lxc.conf

...

$ lxc-attach -n PSMSSP -f /container/PSMSSP/conf/lxc.conf

...

$ lxc-attach -n CCSPPANDM -f /container/CCSPPANDM/conf/lxc.conf

...

$ lxc-attach -n CCSPWIFI -f /container/CCSPWIFI/conf/lxc.conf

...

$ lxc-attach -n CCSPCR -f /container/CCSPCR/conf/lxc.conf

hostapd

hostapd is software daemon used for turning the normal network interface to access point.

Ex:

$ hostapd -B /nvram/hostapd0.conf
