The Envoy build system uses Bazel.
In order to ease initial building and for a quick start, we provide an Ubuntu 16 and a Windows based docker containers that have everything needed inside of it to build and statically link Envoy, see ci/README.md.
In order to build without using the Docker container, follow the instructions at bazel/README.md.
Linux/Mac Target Requirements
Envoy was initially developed and deployed on Ubuntu 14.04 LTS. It should work on any reasonably recent Linux including Ubuntu 20.04 LTS.
Building Envoy has the following requirements:
Recent GCC/Clang versions - please see bazel/README.md#supported-compiler-versions for current requirements.
About 2GB of RAM per core (so 32GB of RAM for 8 cores with hyperthreading). See this FAQ entry for more information on build performance.
These Bazel native dependencies.
Please note that for Clang/LLVM 8 and lower, Envoy may need to be built with
as the new tcmalloc code is not guaranteed to compile with lower versions of Clang.
Windows Target Requirements
Envoy now suports Windows as a target platform. The requirements below only apply if you want to build the Windows native executable. If you want to build the Linux version of Envoy on Windows either with WSL or Linux containers please see the Linux requirements above.
Building Envoy for Windows has the following requirements:
If you’re interested in modifying Envoy and testing your changes, one approach is to use Docker. This guide will walk through the process of building your own Envoy binary, and putting the binary in an Ubuntu container.
