Revert "Disable overcommit accounting on E2 VMs (#865)" (#871) This reverts commit 880daf9de49873d37aa6723dff4bba81542d1ecd.
This repository stores the collection of packages installed on Google supported Compute Engine images.
Table of Contents
The Linux guest environment denotes the Google provided configuration and tooling inside of a Google Compute Engine (GCE) virtual machine. The metadata server is a communication channel for transferring information from a client into the guest. The Linux guest environment includes a set of scripts and daemons (long-running processes) that read the content of the metadata server to make a virtual machine run properly on our platform.
The guest Python code is packaged as a compliant PyPI Python package that can be used as a library or run independently. In addition to the Python package, deb and rpm packages are created with appropriate init configuration for supported GCE distros. The packages are targeted towards distribution provided Python versions.
| Distro | Package Type | Python Version | Init System |
|---|---|---|---|
| SLES 12 | rpm | 2.7 | systemd |
| SLES 15 | rpm | 3.6 | systemd |
| CentOS 6 | rpm | 2.6 | upstart |
| CentOS 7 | rpm | 2.7 | systemd |
| RHEL 6 | rpm | 2.6 | upstart |
| RHEL 7 | rpm | 2.7 | systemd |
| RHEL 8 | rpm | 3.6 | systemd |
| Ubuntu 14.04 | deb | 2.7 | upstart |
| Ubuntu 16.04 | deb | 3.5 or 2.7 | systemd |
| Ubuntu 18.04 | deb | 3.6 | systemd |
| Ubuntu 19.04 | deb | 3.7 | systemd |
| Debian 9 | deb | 3.5 or 2.7 | systemd |
| Debian 10 | deb | 3.7 | systemd |
We build the following packages for the Linux guest environment.
google-compute-engine/usr/bin.instance_setup.python-google-compute-enginepython3-google-compute-enginegoogle-compute-engine-oslogingce-disk-expandThe package sources (RPM spec files and Debian packaging directories) are also included in this project. There are also Daisy workflows for spinning up GCE VM's to automatically build the packages for Debian, Red Hat, and CentOS. See the README in the packaging directory for more details.
Versions are described as 1:YYYYMMDD.NN-gN, meaning epoch 1 to denote from a distro maintained package which will be 0, a date string formatted as year, month, day, an incrementing minor release, and gN representing the Google package release. Debian, Ubuntu, and SUSE maintain distro packages which may be out of date, have different versioning, or naming.
The method for making version updates differs by package.
VERSION variable set in the setup_{deb,rpm}.sh build scripts.debian/changelog file updated. Please use dch(1) to update it.python-google-compute-engine additionally needs the version specified in setup.py. This is used for entry points through the Python egg and PyPI.google-compute-engine-oslogin needs the version also updated in the Makefile.The deb and rpm packages are published to Google Cloud repositories. Debian, CentOS, and RHEL use these repositories to install and update the google-compute-engine, google-compute-engine-oslogin and python-google-compute-engine (and python3-google-compute-engine for Python 3) packages. If you are creating a custom image, you can also use these repositories in your image.
For Debian, run the following commands as root:
Add the public repo key to your system:
curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
Add a source list file /etc/apt/sources.list.d/google-cloud.list and change DIST to either stretch for Debian 9 or buster for Debian 10:
DIST=stretch
sudo tee /etc/apt/sources.list.d/google-cloud.list << EOM
deb http://packages.cloud.google.com/apt google-compute-engine-${DIST}-stable main
deb http://packages.cloud.google.com/apt google-cloud-packages-archive-keyring-${DIST} main
EOM
Install the packages to maintain the public key over time:
sudo apt update; sudo apt install -y google-cloud-packages-archive-keyring
You are then able to install any of the packages from this repo.
For RedHat based distributions, run the following commands as root:
Add the yum repo to a repo file /etc/yum.repos.d/google-cloud.repo for EL6, EL7, or EL8. Change DIST to either 6, 7, or 8 respectively:
DIST=7
tee /etc/yum.repos.d/google-cloud.repo << EOM
[google-compute-engine]
name=Google Compute Engine
baseurl=https://packages.cloud.google.com/yum/repos/google-compute-engine-el${DIST}-x86_64-stable
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://packages.cloud.google.com/yum/doc/yum-key.gpg
https://packages.cloud.google.com/yum/doc/rpm-package-key.gpg
EOM
You are then able to install any of the packages from this repo.

An old CentOS 6 image fails to install the packages with an error on SCL
CentOS 6 images prior to v20160526 may fail to install the package with the error:
http://mirror.centos.org/centos/6/SCL/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Remove the stale repository file: sudo rm -f /etc/yum.repos.d/CentOS-SCL.repo
On some CentOS or RHEL 6 systems, extraneous python egg directories can cause the python daemons to fail.
In /usr/lib/python2.6/site-packages look for google_compute_engine-2.4.1-py27.egg-info directories and google_compute_engine-2.5.2.egg-info directories and delete them if you run into this problem.
Using boto with virtualenv
Specific to running boto inside of a Python virtualenv, virtual environments are isolated from system site-packages. This includes the installed Linux guest environment libraries that are used to configure boto credentials. There are two recommended solutions:
virtualenv venv --system-site-packages.boto via the Linux guest environment PyPI package using pip install google-compute-engine.Have a patch that will benefit this project? Awesome! Follow these steps to have it accepted.
