|

<p>Google Cloud is a cloud computing platform that allows users to
|
||||
run hosted services and servers in a cloud maintained by
|
||||
Google. The goal of this project is to provide an easy way to
|
||||
create and manage &os; installations running on Google
|
||||
Cloud.</p>
|
||||
|
||||
<p>The good news:</p>
|
||||
|
||||
<p>FreeBSD 10.1 runs fine. You can create an image and start it
|
||||
up and login via standard ssh, via the <tt>gcloud</tt> command
|
||||
or via the web console (ssh in a web browser window). More
|
||||
details on how to do all this can be found in the links.
|
||||
Basically, you should be able to <tt>gcutil addimage
|
||||
freebsd-101-release-amd64-20150101032704
|
||||
gs://swills-test-bucket/FreeBSD-10.1-RELEASE-amd64-20150101032704.tar.gz</tt></p>
|
||||
|
||||
<p>Then spin up an image using <tt>gcloud compute instances
|
||||
create --zone us-central1-b --image
|
||||
freebsd-101-release-amd64-20150101032704 --boot-disk-size 20GB
|
||||
gtest1</tt></p>
|
||||
|
||||
<p>These commands are part of the google-cloud-sdk port, which
|
||||
contains all the commands to interact with Google Cloud. There
|
||||
is also a google-daemon port which is used in running instances to
|
||||
create users and set them up and a google-startup-scripts port which
|
||||
handles running startup/shutdown scripts as specified in node
|
||||
metadata.</p>
|
||||
|
||||
<p>Additionally, the firstboot-growfs port has been brought back so
|
||||
that new instances will grow their root filesystem. (Thanks to Colin
|
||||
Percival for having created that port initially.)</p>
|
||||
|
||||
<p>There is also a firstboot-freebsd-update port which can be used
|
||||
to update a system on first boot but is currently disabled. See
|
||||
below. Similarly, the firstboot-pkgs port/scripts will install
|
||||
specified packages on first boot.</p>
|
||||
|
||||
<p>Overall, Google Cloud Compute is quite nice; instances spin up
|
||||
in about 60 seconds and it is very reasonably priced with
|
||||
automatic discounts for longer term usage. There is a $300 credit
|
||||
for first time users that also makes it free to try out. That
|
||||
credit covers quite a lot of time, and the instances are pretty
|
||||
fast, as well, even the ones without SSDs.</p>
|
||||
|
||||
<p>The bad news:</p>
|
||||
|
||||
<p>Google does not make sharing non-official images as easy as
|
||||
AWS, so you have to create your own using my public tar file. The
|
||||
tar was created using the script in the links section. That
|
||||
script can be used to produce customized images, even though there
|
||||
are no official image (nor will there be any time soon).</p>
|
||||
|
||||
<p>There are some issues running FreeBSD on Google Cloud,
|
||||
listed in the tasks section.</p>
|

</body>
|

|

|

<help>
|
||||
<task>
|
||||
<p>The 8 and 16 cpu instances seem to reboot randomly.</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>Repeated UFS panics that Google folks have reported, but
|
||||
I do not think those are particular to Google Cloud. The panic
|
||||
message is "ffs_valloc dup alloc".</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>Running freebsd-update causes the system to become
|
||||
unbootable, so updates do not work. (Reboots work fine
|
||||
otherwise.)</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>There is no <tt>gcimagebundle</tt> command in the Ports
|
||||
Collectiong so you cannot easily create an image from a running
|
||||
machine.</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>There are a few minor issue with the startup script
|
||||
that is supposed to regenerate ssh keys (for when you
|
||||
create an image from an existing system).</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>10.1 works, but 10.0 does not boot; other versions remain
|
||||
untested.</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>The kern.vm_guest sysctl node does not detect that it is in a
|
||||
guest.</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>The vtnet driver needs wq disabled on 16 cpu boxes, but
|
||||
is just disabled everywhere for now since that is easier.</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>There is a work needed for the Google
|
||||
<tt>safe_format_and_mount</tt> command which formats and
|
||||
mounts newly attached disks, but this is just a nicety really.</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>I need to look into irq affinity for vtnet.</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>We need to support virtualized clocks; bryanv@ is
|
||||
working on this. In fact, all his ongoing work in the virt area
|
||||
would probably make things work better.</p>
|
||||
</task>
|
||||
|
||||
<task>
|
||||
<p>It would be nice if there as the ability to disable the
|
||||
spinner before the loader, which clutters up the console log. The
|
||||
ability to disable it is in HEAD; hopefully it will be MFCd to
|
||||
10-STABLE before 10.2.</p>
