platform:

In this case, it is the hardware enablement kernel for 16.04. To find
the exact kernel version that will be deployed, we must look into the
simple-stream image cache that will be used by MaaS to deploy nodes
with. Locate the ``data/images/ucp/maas/maas_cache`` key in within
``airship-treasuremap/global/software/config/versions.yaml``. This
is the image that you will need to fetch, using a node with docker
installed that has access and can reach the site/location hosting the
image. For example, from the **build node**, the command would take the
form:
::
sudo docker pull YOUR_SSTREAM_IMAGE
Then, create a container from that image:
::
cd ~
sudo sh -c "$(docker images | grep sstream-cache | head -1 | awk '{print $1}' > image_name)"
sudo docker create --name sstream $(cat image_name)
Then use the container ID returned from the last command as follows:
::
sudo docker start sstream
sudo docker exec -it sstream /bin/bash
In the container, ``cd`` to the following location (substituting for the
platform image and platform kernel identified in the host profile
previously, and choosing the folder corresponding to the most current
date if more than one are available) and run the ``file`` command on the
``boot-kernel`` file:
::
cd /var/www/html/maas/images/ephemeral-v3/daily/PLATFORM_IMAGE/amd64/LATEST_DATE/PLATFORM_KERNEL/generic
file boot-kernel
This will produce the complete kernel version. E.g.:
::
Linux kernel x86 boot executable bzImage, version 4.13.0-43-generic (buildd@lcy01-amd64-029) #48~16.04.1-Ubuntu S, RO-rootFS, swap_dev 0x7, Normal VGA
platform:
image: 'xenial'
kernel: 'hwe-16.04'
kernel_params:
kernel_package: 'linux-image-4.15.0-34-generic'
In this example, the kernel version is ``4.13.0-43-generic``. Define any proxy
environment variables needed for your environment to reach public ubuntu

``sudo apt remove``, so that the newly install kernel is the latest
available.
Lastly if you wish to cleanup your build node, you may run the
following:
::
exit # (to quit the container)
cd ~
sudo docker stop sstream
sudo docker rm sstream
sudo docker image rm $(cat image_name)
sudo rm image_name
Install ntpdate/ntp
