Software Installation and Upgrade Overview
Software installation and upgrade for F5OS on rSeries platforms
rSeries
platforms F5
rSeries
platforms are powerful systems
that are designed specifically for application delivery performance and
scalability.rSeries
introduces a new
platform layer called F5OS
. Your rSeries
system comes with a default
version of F5OS
software
pre-installed. To use new features and software fixes, you will want to
periodically upgrade the software on your system.F5OS software image layers
There are
two
layers of F5OS
software images for rSeries
systems.- System layer
- This is the base software (Base OS) for the system. It is subdivided into operating system (OS) and platform services components.
- Tenant layer
- Tenants are guest systems running software on the system (for example, aBIG-IPsystem).F5provides different tenant images for different uses.
Installation and upgrade types
There are four types of
F5OS
software
installation/upgrades for rSeries
systems.- Full system release
- Contains everything needed for the platform layer for a system.
- Full component release
- Contains the full installation for a specific platform layer, including both host and service components.
- Partial component release
- Contains sub-components of a specific platform layer (host.os or services.img). Partial component releases contain all containers for that release.
- Patch/Hotfix release
- Contains a subset of services/container packages specific for a component (specific os patches or service containers).
Appliance mode
The
rSeries
system can be run in appliance mode
. Appliance mode
adds a layer of security by allowing users access only to the system command line
interface (CLI) and removing user access to root and the Bash shell. When enabled, the
root user cannot log in to the device by any means, including from the serial
console.For greater security, it is highly recommended that you
configure the system to run in appliance mode.
For more information on configuring appliance mode, see
