Building Envoy from Source
While the Mode Envoy build guide focuses on physical assembly‚ building Envoy
from source refers to compiling the software. This involves obtaining the
source code and using build tools to create executable binaries.
Prerequisites for Building from Source
Before embarking on the journey of building Envoy from source‚ certain
prerequisites must be met to ensure a smooth and successful compilation
process. Primarily‚ a suitable development environment needs to be
established. This typically involves a Linux-based operating system‚ such
as Ubuntu‚ due to its widespread support and comprehensive documentation.
Alternatively‚ macOS can also be used‚ although some configurations might be
necessary.
Furthermore‚ essential software packages must be installed. These include a
C++ compiler‚ such as GCC or Clang‚ along with the Bazel build system‚ which
is instrumental in managing the build process. Additionally‚ CMake‚ a
cross-platform build system generator‚ may also be required.
It’s also crucial to have sufficient disk space‚ generally around 4-5 GB‚ to
accommodate the source code and build artifacts. Network connectivity is
essential for downloading dependencies. Finally‚ familiarity with command-line
tools and basic software development concepts is highly recommended for
effective troubleshooting and debugging.
Using the Envoy Docker Image for Building
Leveraging the Envoy Docker image offers a streamlined and isolated
environment for building Envoy‚ eliminating many dependency-related issues.
This approach encapsulates all necessary build tools and libraries within the
container‚ ensuring consistency across different systems. The
`envoyproxy/envoy-build-ubuntu` image is commonly used‚ providing a
pre-configured environment suitable for building Envoy.
To begin‚ ensure Docker is installed and running on your system. Next‚ pull
the desired Envoy build image from Docker Hub using the `docker pull` command.
Once the image is downloaded‚ you can run a container from it‚ mounting your
local Envoy source code directory into the container.
Inside the container‚ you can then execute the necessary build commands‚ such
as those provided by Bazel‚ to compile Envoy. This process isolates the build
environment‚ preventing conflicts with your host system’s configuration;
The resulting Envoy binary can then be extracted from the container and used
as needed. This method simplifies the build process and enhances
reproducibility.
Building on Different Platforms
Envoy can be built on various platforms‚ including Linux and Windows.
Building on each platform may require specific tools and configurations.
Understanding these platform-specific requirements is essential for a
successful build process and avoid potential issues.
Building on Linux
Building Envoy on Linux involves several key steps to ensure a smooth and
successful process. First‚ verify that your Linux distribution is up to
date with the latest security patches and software updates. This helps
prevent compatibility issues and ensures you have the necessary tools
available. Next‚ install the required dependencies‚ including compilers
(such as GCC or Clang)‚ build tools (like Make)‚ and other essential
libraries.
Using a package manager like apt or yum can simplify this process. After
installing the dependencies‚ download the Envoy source code from the
official repository or a trusted source. Once you have the source code‚
navigate to the Envoy directory in your terminal. Follow the instructions
provided in the Envoy documentation to configure the build environment.
This may involve setting environment variables and specifying build
options. Finally‚ initiate the build process using the appropriate build
command‚ such as make build or bazel build‚ depending on the
build system you choose. Monitor the build process for any errors or
warnings.
Building on Windows (Experimental)
Building Envoy on Windows is currently considered an experimental process‚
which means it may involve some challenges and require specific
configurations. To begin‚ ensure you have a suitable Windows development
environment set up. This typically includes installing Visual Studio with
the necessary C++ toolchain and the Windows SDK. Additionally‚ you’ll
need to install Bazel‚ the build system used by Envoy‚ and configure it to
work with your Visual Studio installation.
Given the experimental nature‚ it’s crucial to consult the official Envoy
documentation for the most up-to-date instructions and any specific
requirements for Windows builds. The documentation may provide details on
setting environment variables‚ configuring build options‚ and addressing
potential compatibility issues.
It’s also advisable to check the Envoy project’s issue tracker or community
forums for any known issues or workarounds related to Windows builds. Since
the Windows build is experimental‚ be prepared to encounter unexpected
errors or limitations. Contributions to improve the Windows build process
are always welcome and can help advance the platform’s support.
Building with Bazel
Envoy utilizes the Bazel build system‚ offering reproducible and efficient
builds. Building with Bazel requires a correctly configured environment
and understanding of Bazel commands. This method supports building without
Docker‚ providing flexibility.
Bazel Build System
The Bazel build system is central to building Envoy from source. Bazel
ensures that builds are reproducible‚ fast‚ and scalable. It manages
dependencies efficiently and supports various platforms. To begin‚ ensure
Bazel is installed and configured correctly on your system.
The Envoy repository contains `BUILD` files that define how the project is
structured and built. These files specify dependencies‚ build targets‚ and
other essential build configurations. When building with Bazel‚ the system
automatically resolves dependencies and compiles the necessary code.
The primary command for building Envoy is `bazel build`. You can specify
targets such as `//source/exe:envoy` to build the Envoy executable. Bazel
will then analyze the dependencies‚ compile the code‚ and link everything
together to produce the final binary. This process ensures that all
required components are built in the correct order.
Bazel also supports incremental builds‚ meaning it only rebuilds what has
changed since the last build. This significantly speeds up the build
process‚ especially when making small changes to the codebase. By
leveraging Bazel’s caching and dependency management features‚ building
Envoy becomes more efficient and reliable.
Building Without Docker
Building Envoy without Docker offers an alternative approach for developers
who prefer a native build environment. This method requires manual
installation of all necessary dependencies and build tools‚ including Bazel‚
protocol buffers‚ and other libraries. Ensure your system meets the
prerequisites outlined in the Envoy documentation before proceeding.
The primary advantage of building without Docker is greater control over the
build environment. Developers can customize the build process and optimize
it for their specific hardware and software configurations. However‚ this
approach also introduces complexity‚ as managing dependencies and ensuring
consistency across different environments can be challenging.
To build Envoy without Docker‚ navigate to the Envoy repository and follow
the instructions in the `bazel/README.md` file. This file provides
detailed steps for configuring your environment and building the Envoy
binary using Bazel. Pay close attention to the required environment
variables and build flags.
Remember that building without Docker may require troubleshooting dependency
issues and resolving build errors manually. Consult the Envoy community
forums and documentation for assistance. Once the build is complete‚ the
Envoy binary will be located in the Bazel output directory‚ ready for
deployment and testing.
Installing Pre-built Binaries
Installing pre-built binaries is the fastest way to get started with Envoy.
Download the latest binary for your target platform from the official Envoy
website. Verify the integrity of the downloaded file before installation.
Downloading Pre-built Binaries
To quickly begin using Envoy‚ downloading pre-built binaries is the most
expedient method. These binaries are readily available for various
platforms‚ making the initial setup straightforward. Begin by navigating to
the official Envoy proxy releases page‚ typically found on the project’s
GitHub repository or website. Here‚ you’ll find a comprehensive list of
releases‚ each accompanied by pre-built binaries tailored for specific
operating systems and architectures.
Carefully select the binary that corresponds to your target environment‚
ensuring compatibility with your system’s architecture (e.g.‚ x86_64‚ ARM).
Once you’ve identified the appropriate binary‚ download it to a convenient
location on your machine. After downloading‚ it’s crucial to verify the
integrity of the file. This can be achieved by comparing the SHA256 checksum
provided alongside the download link with the checksum of the downloaded
file.
This step ensures that the binary hasn’t been tampered with during the
download process. With the binary downloaded and verified‚ you’re ready to
proceed with the installation.
Troubleshooting Build Issues
Encountering issues during the Envoy build process is not uncommon‚ but with
a systematic approach‚ most problems can be resolved. A frequent culprit is
missing dependencies. Ensure all prerequisites‚ such as Bazel and the
required libraries‚ are correctly installed and configured. Consult the
official Envoy documentation for a comprehensive list of dependencies
specific to your operating system;
Another common issue arises from incorrect environment variables. Verify
that essential variables like JAVA_HOME and PATH are
properly set and point to the correct locations. Build errors can also stem
from corrupted source code. If you suspect this‚ try cleaning your Bazel
cache using the bazel clean --expunge command and re-attempt
the build.
Furthermore‚ compatibility issues between different versions of tools can
cause problems. Ensure that you are using the recommended versions of Bazel‚
GCC‚ and other build tools as specified in the Envoy documentation. If
you’re still facing difficulties‚ consult the Envoy community forums or
Stack Overflow for solutions to common build errors. Providing detailed
information about your environment and the error messages you’re
encountering will help others assist you more effectively.
