Operating system details

Some operating system images are customized specifically to run on Compute Engine and have notable differences from the standard images that come directly from the operating system vendor.

The following sections provide more information about these differences.

CentOS

CentOS is a free operating system platform that is derived from the sources of Red Hat Enterprise Linux (RHEL).

Automatic updates

By default, this operating system is configured to install security updates by using the RHEL yum-cron or dnf-automatic tool. The updates have the following behaviors:

  • The yum-cron or dnf-automatic does not upgrade VMs between major versions of the operating system.
  • For CentOS 7 and CentOS 8, the upgrade tool is configured to only apply updates marked by the vendor as security updates.
  • Some updates require reboots to take effect. These reboots do not happen automatically.
Notable differences from standard CentOS images

The CentOS images that are provided by Compute Engine, have the following differences in configuration from standard CentOS images:

Package system and repository configuration

  • Google Cloud repositories are enabled to install packages for the Compute Engine guest environment and the Cloud SDK.
  • Repositories are set to use the CentOS default mirror network.
    • For CentOS 8, the PowerTools repository is enabled.
    • For CentOS 7, EPEL is enabled.
  • Automatic updates are configured as follows:
    • For CentOS 7, automatic updates are enabled by using yum-cron.
    • For CentOS 8+, automatic updates are enabled by using dnf automatic.
    • For all versions, the update_cmd property is set to security .However, by default CentOS does not offer security tagged repositories.
    • IPv6 endpoints are disabled in the yum or dnf config files for all versions.

Network configuration

  • The network interface MTU is set to 1460.
  • IPv6 is enabled.
  • The DHCP client is set to retry every 10 seconds instead of every 5 minutes. The client is also set to persistent mode instead of oneshot.
  • The SSH server configuration is set up as follows:
    • Password authentication is disabled.
    • To prevent SSH disconnections, ServerAliveInterval and ClientAliveInterval are set to 7 minutes.
    • Root login is disabled.
  • /etc/udev/rules.d/75-persistent-net-generator.rules is disabled.
  • To prevent MAC addresses from persisting, /etc/udev/rules.d/70-persistent-net.rules is removed.
  • By default, all traffic is allowed through the guest firewall because the VPC firewall rules overrides the guest firewall rules. The guest firewall rules remains enabled and can be configured through normal CentOS methods.

Bootloader configuration

  • To force faster boot times, the boot timeout in the grub configuration is set to 0.
  • The I/O scheduler is set to noop.

Additional configuration

  • By default, images are 20 GB. This is the recommended minimum size.
  • The partition table is GPT, and there is an EFI partition to support booting on UEFI.
  • There are no local users configured with passwords.
  • The NTP server is set to use the Compute Engine metadata server.
  • The floppy module is disabled because there is no floppy disk controller on Compute Engine .

Ubuntu LTS

Ubuntu is a free operating system developed and supported by Canonical.

Ubuntu Long Term Support (LTS) images receive bug fixes and security updates for five years after their release date. LTS images can run on your instances for several years without having to upgrade to a newer release.

Ubuntu Minimal images are supported the same as Ubuntu LTS images.

Regular (non LTS) Ubuntu images are supported for 9 months from their release date. To continue to use a regular Ubuntu image, you will have to upgrade to the next regular Ubuntu release or LTS release after the support cycle ends to receive fixes and updates. Compute Engine recommends using Ubuntu LTS images unless you require features or software packages that are not yet included in an LTS release. If your instances run Ubuntu releases that are no longer supported, upgrade to a supported Ubuntu release.

Automatic updates

By default, this operating system is configured to install security updates by using the Ubuntu AutomaticSecurityUpdates tool. The updates have the following behaviors:

  • The AutomaticSecurityUpdates tool does not upgrade VMs between major versions of the operating system.
  • The AutomaticSecurityUpdates tool is configured to only automatically apply updates obtained from the Ubuntu security repository.
  • Some updates require reboots to take effect. These reboots do not happen automatically.
Notable differences from standard Ubuntu images

Ubuntu images are built and maintained by Canonical. Ubuntu images are always built with the latest Ubuntu packages which reflect the most recent Ubuntu point release.

The Ubuntu images that are provided by Compute Engine, have the following differences in configuration from standard Ubuntu images:

Package system and repository configuration

  • The guest environment for Compute Engine packages are installed from the Ubuntu supplied packages.
  • For Ubuntu 18.04+, the Cloud SDK is installed and maintained as a snap package.
  • The APT sources are set to use the Ubuntu Compute Engine mirrors via cloud-init.
  • The Unattended-upgrades package is installed and configured to download and install Debian security updates daily. This can be configured or disabled by changing the values in /etc/apt/apt.conf.d/50unattended-upgrades and /etc/apt/apt.conf.d/02periodic.
  • The linux-image-gcp kernel is used instead of the generic Ubuntu kernel. The Google Cloud kernel reflects the latest rolling HWE kernel for Ubuntu LTS.

Network Configuration

  • IPv6 is enabled.
  • The SSH server configuration is set to disable password authentication.
  • To prevent MAC addresses from persisting, /etc/udev/rules.d/70-persistent-net.rules is removed.

Bootloader configuration

  • To force faster boot times, the boot timeout in the grub configuration is set to 0.
  • To allow SCSI block multi-queue usage, scsi_mod.use_blk_mq is enabled.

Additional configuration

  • Images are 10 GB by default.
  • The partition table is GPT, and there is an EFI partition to support booting on UEFI. There is also an MBR boot block to support BIOS.
  • Ubuntu uses cloud-init to do some boot time initialization. The cloud.cfg file is configured for Compute Engine and enables only the cloud-init modules that are used.
  • There are no local users configured with passwords.
  • The NTP server is set to use the Compute Engine metadata server.
  • The floppy module is disabled because there is no floppy disk controller on Compute Engine.
Support

This operating system is supported by an open source project or community.

This operating system also has premium support available for purchase from Ubuntu. For information about purchasing and using premium support, see the Ubuntu documentation.

General information

For information about non LTS Ubuntu releases, see Ubuntu release wiki.
