Building Envoy - linux-on-ibm-z/docs GitHub Wiki

Building Envoy

The instructions provided below specify the steps to build Envoy version 1.34.0 on Linux on IBM Z for the following distributions:

  • RHEL (8.10, 9.4, 9.5, 9.6)
  • SLES 15 SP6
  • Ubuntu (22.04, 24.04, 24.10, 25.04)

General Notes:

  • When following the steps below please use a standard permission user unless otherwise specified.
  • A directory /<source_root>/ will be referred to in these instructions, this is a temporary writable directory anywhere you'd like to place it.

Build and Install Envoy

1. Build using script

If you want to build Envoy using manual steps, go to Step 2.

Use the following commands to build Envoy using the build script. Please make sure you have wget installed.

wget -q https://raw.githubusercontent.com/linux-on-ibm-z/scripts/master/Envoy/1.34.0/build_envoy.sh

# Build Envoy
bash build_envoy.sh   [Provide -t option for executing build with tests]

In case of error, check logs for more details or go to STEP 2 to follow manual build steps.

  • Download Envoy and Apply Patches

    cd "$SOURCE_ROOT"/
git clone --depth 1 -b 1.34.0 https://github.com/envoyproxy/envoy.git
cd envoy

./bazel/setup_clang.sh "/usr" ### For RHEL and SLES only
./bazel/setup_clang.sh "/usr/lib/llvm-14" ### For Ubuntu only

# Set the location of the s390x cargo-bazel binary required by rules_rust
echo "build --repo_env=CARGO_BAZEL_GENERATOR_URL=file:${SOURCE_ROOT}/cargo-bazel" >> "${SOURCE_ROOT}/envoy/user.bazelrc"
# Set the location of the s390x buf binaries required by rules_buf
echo "build --repo_env=BUFBUILD_BUF_TOOLCHAIN_URL=file:${SOURCE_ROOT}/rules_buf" >> "${SOURCE_ROOT}/envoy/user.bazelrc"
# Disable heap checking because it slows down the tests and causes timeouts
echo "build --test_env=HEAPCHECK=" >> "${SOURCE_ROOT}/envoy/user.bazelrc"
echo "test --test_env=HEAPCHECK=" >> "${SOURCE_ROOT}/envoy/user.bazelrc"

# Apply patches to allow envoy to build
curl -sSL $PATCH_URL/envoy-build.patch | git apply -

# Apply patches for failing tests
curl -sSL $PATCH_URL/envoy-test.patch | git apply -

curl -sSL $PATCH_URL/grpc-s390x.patch > $SOURCE_ROOT/envoy/bazel/grpc-s390x.patch

  • Build Envoy

    bazel build envoy -c opt --config=clang

The binary will be generated in $SOURCE_ROOT/envoy/bazel-bin/source/exe/envoy-static.

  • Verify the version of Envoy 
    $SOURCE_ROOT/envoy/bazel-bin/source/exe/envoy-static --version
    Output should be similar to: 
    bazel-bin/source/exe/envoy-static  version: d7809ba2b07fd869d49bfb122b27f6a7977b4d94/1.34.0/Modified/RELEASE/BoringSSL

4. Test (optional)

cd $SOURCE_ROOT/envoy
  • Run Tests 
    bazel test //test/... -c opt --config=clang --keep_going

Notes:

  • Below mentioned test failures are observed on all distros on Intel and s390x:

    • //test/extensions/filters/listener/original_dst:original_dst_integration_test: To fix the test, follow official doc to set up the original_dst filter for a quick manual test. To run this test after applying this fix, the following command can be used. 
      bazel test //test/extensions/filters/listener/original_dst:original_dst_integration_test -c opt --config=clang

  • Below mentioned test failure is observed on all RHEL and SLES distros on Intel and s390x:

    //test/config_test:example_configs_test: This test fails because the file "/etc/ssl/certs/ca-certificates.crt" only exists on debian like systems.

  • Some tests are flaky and may fail randomly. Individual tests can be re-run with a command like:

    ```bash
bazel test <bazel test target> -c opt --config=clang
```
