This article will guide you on how to compile the Istio binaries and Docker images on macOS.
Before you begin
Before we start, refer to the Istio Wiki , here is the information about my build environment.
- macOS 12.3.1 Darwin AMD64
- Docker Desktop 4.8.1(78998)
- Docker Engine v20.10.14
Start to compile
First, download the Istio code
from GitHub to the $GOPATH/src/istio.io/istio directory, and execute the commands below in that root directory.
Compile into binaries
Execute the following command to download the Istio dependent packages, which will be downloaded to the vendor directory.
go mod vendor
Run the following command to build Istio:
sudo make build
If you do not run the command with sudo, you may encounter the following error.
fatal: unsafe repository ('/work' is owned by someone else)
To add an exception for this directory, call:
git config --global --add safe.directory /work
fatal: unsafe repository ('/work' is owned by someone else)
To add an exception for this directory, call:
git config --global --add safe.directory /work
Makefile.core.mk:170: *** "TAG cannot be empty". Stop.
make: *** [build] Error 2
Even if you follow the prompts and run git config --global --add safe.directory /work, you will still get errors during compilation.
The compiled binary will be saved in out directory with the following directory structure.
out
├── darwin_amd64
│ ├── bug-report
│ ├── client
│ ├── envoy
│ ├── extauthz
│ ├── install-cni
│ ├── istio-cni
│ ├── istio-cni-taint
│ ├── istio-iptables
│ ├── istio_is_init
│ ├── istioctl
│ ├── logs
│ ├── operator
│ ├── pilot-agent
│ ├── pilot-discovery
│ ├── release
│ └── server
└── linux_amd64
├── envoy
├── envoy-centos
├── logs
└── release
It will build both the linux_amd64 and darwin_amd64 architectures binaries at the same time.
Compile into Docker images
Run the following command to compile Istio into a Docker image.
sudo make docker
The compilation will take about 3 to 5 minutes depending on your network. Once the compilation is complete, you will see the Docker image of Istio by running the following command.
$ docker images

You can change the image name and push it into your own container registry.
Summary
This is how to build Istio on macOS. If you have already downloaded the Docker image you need to build, the build will take less than a minute. It also takes only a few minutes to build Docker images.
