FreeBSD 10.3-RELEASE Announcement
FreeBSD 10.3-RELEASE amd64 is also available on these cloud hosting platforms:

Google® Compute Engine™:
Instances can be deployed using the gcloud utility:

% gcloud compute instances create INSTANCE \
--image freebsd-10-3-release-amd64 \
--image-project=freebsd-org-cloud-dev
% gcloud compute ssh INSTANCE
Replace INSTANCE with the name of the Google Compute Engine instance.

So i have just to upload FreeBSD 10.3 amd64 intro my bucket and click install ?
I mean is not needed to convert image ?
No, you do not use the normal amd64 image that you would install on a standalone PC. You use the special pre-prepared public image through Google's cloud management tools, as described in the section of the release announcement that I quoted above. Here it is again:
Code:
      % gcloud compute instances create INSTANCE \
        --image freebsd-10-3-release-amd64 \
        --image-project=freebsd-org-cloud-dev
      % gcloud compute ssh INSTANCE
See also: Although Google's docs do not currently list FreeBSD, their docs for Linux should mostly be appropriate for things outside the running instance (you just need to use the FreeBSD images instead of Linux images, and then do things the normal FreeBSD way inside the running instance).

Well I prefer to make a special image.

But I have just one problem...

After complete install of FreeBSD I don't know which password to use.

I used this script to make the custom image:
Code:

My question is, what password will be assigned to user root after installing?
How I can do to set a password after installation is done?
My idea was to add this maybe I added it wrong? If someone has an idea please reply.
Code:
echo root | pw mod user root -h 0
But it does not work, still says wrong password.

PS: I don't want the google cloud packages, I want a clean very clean fresh installed system.

Official FreeBSD-11 is available on Google cloud platform. You can spin up one with:
Code:
gcloud compute instances create NAME --image freebsd-11-0-release-amd64  --image-project=freebsd-org-cloud-dev --machine-type MTYPE --zone ZONE
If you are new to GCP, first you have to create a network. Here is an example:

Code:
gcloud compute networks create default
gcloud compute firewall-rules create default-allow-icmp --network default --allow icmp --source-ranges 0.0.0.0/0
gcloud compute firewall-rules create default-allow-ssh --network default --allow tcp:22 --source-ranges 0.0.0.0/0
gcloud compute firewall-rules create default-allow-internal --network default --allow tcp:0-65535,udp:0-65535,icmp --source-ranges 10.128.0.0/9

I understand your desire to configure the OS to your liking. Please know, though, that there are some configuration steps and required packages that cannot be left out, when you do this. Here is the github repo (not mine) of a shell script to help prepare a FreeBSD image:

https://github.com/swills/FreeBSD-gcloud/blob/master/build_google_image.sh

(Note the inclusion of certain packages to be included with the image, such as "google-shell-scripts")

I found this by following a 3-year-old comment to a 4-year-old thread on the subject at:

https://groups.google.com/forum/#!msg/gce-discussion/YWoa3Aa_49U/FYAg9oiRlLUJ

I cannot vouch for the correctness of this script (which was last updated two years ago) since I have not personally used it, but I suspect that combining elements from it with your own script, as well as considering the advice at the top of the google groups forum post, will lead you in the right direction.

FreeBSD 11.1 works fine with cloud.google.com/

> gcloud compute instances create "INSTANCE" --image freebsd-11-1-stable-amd64-2017-10-13 --image-project=freebsd-org-cloud-dev --machine-type "g1-small" --boot-disk-size "22"


Transfer the public key to the INSTANCE

> gcloud compute project-info add-metadata --metadata-from-file sshKeys=gcloud.ssh-keys


Format of the file gcloud.ssh-keys should be
Code:
[REMOTE-USERNAME]:ssh-rsa [KEY_VALUE] [LOCAL-USERNAME]
where:
REMOTE-USERNAME is the user whose account in the remote system shall be used to login. In most cases the name of the account (name before @gmai.com). Public key shall be copied to ~/.ssh/authorized_keys
LOCAL-USERNAME is the user whose public key ~/.ssh/id_rsa.pub shall be copied
Then ssh to the INSTANCE

> whoami
LOCAL-USERNAME
> ssh REMOTE-USERNAME@IP-OF-THE-INSTANCE




Documentation "Formatting your public SSH key files" does not describe the format correctly
https://cloud.google.com/compute/docs/instances/adding-removing-ssh-keys#sshkeyformat
https://issuetracker.google.com/issues/67996842

Shawns-Mac-Pro:~ shawn$ gcloud compute instances create "diablita" --zone "us-west1-a" --boot-disk-size "60" --boot-disk-type "pd-ssd" --image "freebsd-11-1-release-amd64" --image-project=freebsd-org-cloud-dev --machine-type "n1-standard-1"


The SSH Keys do not work. In order to make them work I had to:

I copied the content of ~/.ssh/id_rsa.pub and ~/.ssh/google_compute_engine.pub to the vm instances ~./ssh/authorized_keys. I also added them to the VM Instances Details under the SSH Keys section.

Otherwise I get the following error error:

I tried what Vladimir Botka suggested in his post, but I get error (after having put the public key information into gcloud.ssh-keys:
