Patching AWS OpsWorks Stacks¶
Rackspace’s recommended method for securing OpsWorks Stacks with current software updates is to replace the instances with new instances. New instances will have the latest set of security patches installed during bootstrapping. Once the new instances are online, the old instances can be deleted. For more detailed information on this or the alternative options listed below, see Managing Linux Security Updates in the AWS OpsWorks User Guide.
Run the Update Dependencies stack command (Chef 11.10 or older stacks), which will install updates in-place on the instances.
Set the InstallUpdatesOnBoot parameter to false for the instances or layer, and install updates manually using OS management access.
