Cloud Run functions runs in an environment consisting of an
operating system version with add-on packages, language support, and the
Functions Frameworks
library that supports and invokes your function. This environment is
identified by the language version, and is known as the runtime. There are
multiple programming languages available: Node.js, Python, Go, Java,
Ruby, PHP, and .NET.
