DC/OS on GCE Ubuntu - google-compute-engine

Question

Is there any link/documentation available around installing DC/OS on Google Compute Engine where instances are ubuntu 16.04 instances including the bootstrap node instead of CentOS 7?
Currently , the documents I find use Ansible and CentOS 7 on GCE as below.

Short answer: Debian based distributions are currently (at least up to DC/OS 1.10) not supported.
Long answer: It's possible, but requires some extra steps.
DC/OS doesn't use any RedHat specific features. Most important differences could be solved by symlinks for few system binaries, as RedHat systems have different paths and systemd doesn't support $PATH variable in service definition. You'll need following:
sudo apt-get install libcurl3-nss ipset selinux-utils curl unzip bc
sudo ln -s /bin/mkdir /usr/bin/mkdir
sudo ln -s /bin/ln /usr/bin/ln
sudo ln -s /bin/tar /usr/bin/tar
sudo ln -s /bin/rm /usr/bin/rm
sudo ln -s /usr/sbin/useradd /usr/bin/useradd
sudo ln -s /bin/bash /usr/bin/bash
sudo ln -s /sbin/ipset /usr/sbin/ipset
Another requirements are:
systemd with version >=200
Docker >=1.6
Slightly outdated scripts from John Omernik, there's also puppet module (I'm the author). For further details see discussion on DC/OS Jira.
Next step is manual DC/OS compilation (it might sound scary, but actually it's very easy). C++ components (especially mesos-slave) are dependent on system libraries and they'd better be linked to proper libraries.
apt install python3-venv build-essential git
git clone https://github.com/dcos/dcos
./build_local.sh
Resulting "image" will be located in:
$HOME/dcos-artifacts/testing/`whoami`/dcos_generate_config.sh
You can copy it to your bootstrap server and extract:
bash dcos_generate_config.sh --genconf
after updating genconf/config.yaml you can start a container for serving the installation scripts:
docker run -d -p 9090:80 -v $PWD/genconf/serve:/usr/share/nginx/html:ro nginx
On a new node simply fetch the installation script:
rm -rf /tmp/dcos && mkdir /tmp/dcos && cd /tmp/dcos && curl -O http://bootstrap.example.com:9090/dcos_install.sh
bash dcos_install.sh slave
Unless you don't want to run packages from DC/OS Universe (like Elastic, Kafka, etc.) that depends on libmesos-bundle, you might be just fine. The bundle is fetched into each executor's directory, it includes numerous libraries, such as libmesos.so

Some libraries might be compatible with your system, but the versions between CentOS and Debian might (and will) differ. You might encounter errors like:
libmesos-bundle/lib/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by curl)
which will cause that all agent based health checks that use curl won't work, therefore most instances will refuse to start.
