System requirements for the Ruby agent

Important

The Ruby Agent is not currently being sold to new customers. Please contact our Sales team if you have any questions about our offerings and support for the Ruby language.

Before installing the Ruby agent, your system must meet the following requirements:

  • There is a deployed application to be analyzed, and the web application technology is supported by Contrast.

  • The application can be restarted.

  • The web server has network connectivity with Contrast.

  • The web server has network connectivity with RubyGems or the agent manually installed.

  • The server meets the minimum requirements shown in this table.

    Versions

    Notes

    Operating system

    • 64-bit Linux (recommended)

    • 64-bit Alpine

    Starting with agent version 3.0.0, the gem installation step requires the compilation of C extensions. This process is automatic, but you may need to install the following in the target environment:

    • gcc, make, automake and autoconf (Package names may vary. You may install your platform's version of build-essential.)

    • system headers

    The agent runs in the Ruby application layer with some C dependencies so it may need to be installed with the --platform ruby flag to allow for compilation in either g libc or musl libc based systems.

    Ruby gems

    • ougai: ~>1.8 (1.8 and later, earlier than 2)

    • rack: >=2.0 (2.0 and later)
