Which installation method for OneAgent is NOT mentioned?

The installation method for OneAgent that is not mentioned in the context of standard installation options is the Docker container. While the other options listed represent well-documented and commonly used methods for installing OneAgent, the use of a Docker container specifically as a standalone installation method is less frequently mentioned.

OneAgent can be installed using shell scripts which are versatile and can be run across various operating systems. The MSI installer is specifically designed for the Windows platform, allowing for an easy installation process. Moreover, deployment tools such as Chef, Puppet, or Ansible are integrated methods that can automate the installation and management of OneAgent across multiple servers in an environment.

Thus, while Docker containers may be used for containerized environments, they don't serve as the traditional installation method for OneAgent in the same way the other options do, which are explicitly highlighted in the documentation and practical implementations.
