Envoy: Build envoy binary failed

[zqzzq]

Description:
I cloned the envoy project to the local by

git clone https://github.com/envoyproxy/envoy.git

But when I built it, something went wrong :

# pwd
/root/zq/src/envoy
# ./ci/run_envoy_docker.sh './ci/do_ci.sh bazel.dev'    
No remote cache bucket is set, skipping setup remote cache.
ENVOY_SRCDIR=/source
fatal: Not a git repository (or any parent up to mount point /build)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).

is there something I need to set?

A couple of guesses:
1) Are you sure the run_envoy_docker.sh is running correctly, taking the second command as an argument?
2) Can you double check the .git folder is still there?

When I try ./ci/run_envoy_docker.sh './ci/do_ci.sh bazel.dev' I get something that looks like:

$ ./ci/run_envoy_docker.sh './ci/do_ci.sh bazel.dev'

If I run just ./ci/do_ci.sh bazel.dev without the run_envoy_docker.sh script, then I get something pretty similar to what you posted:

$ ./ci/do_ci.sh bazel.dev

@derekargueta I just cloned it and didn't change anything. And I can find .git folder by

# ll -a
...
drwxr-xr-x  8 root root   163 Jun 11 09:54 .git
...

Is it because this folder is hidden?

[derekargueta]

No that should be fine.

Can you double check my comment about run_envoy_docker.sh? I'd think you should also see some Docker output for pulling the image, I'm wondering why that is not showing.

[zqzzq]

This is the script content, I am sorry, I don't understand the script very well.

# cat run_envoy_docker.sh 
#!/bin/bash

set -e

. ci/envoy_build_sha.sh

# We run as root and later drop permissions. This is required to setup the USER
# in useradd below, which is need for correct Python execution in the Docker
# environment.
USER=root
USER_GROUP=root

[[ -z "${IMAGE_NAME}" ]] && IMAGE_NAME="envoyproxy/envoy-build-ubuntu"
# The IMAGE_ID defaults to the CI hash but can be set to an arbitrary image ID (found with 'docker
# images').
[[ -z "${IMAGE_ID}" ]] && IMAGE_ID="${ENVOY_BUILD_SHA}"
[[ -z "${ENVOY_DOCKER_BUILD_DIR}" ]] && ENVOY_DOCKER_BUILD_DIR=/tmp/envoy-docker-build

[[ -f .git ]] && [[ ! -d .git ]] && GIT_VOLUME_OPTION="-v $(git rev-parse --git-common-dir):$(git rev-parse --git-common-dir)"

mkdir -p "${ENVOY_DOCKER_BUILD_DIR}"
# Since we specify an explicit hash, docker-run will pull from the remote repo if missing.
docker run --rm -t -i -e HTTP_PROXY=${http_proxy} -e HTTPS_PROXY=${https_proxy} \
  -u "${USER}":"${USER_GROUP}" -v "${ENVOY_DOCKER_BUILD_DIR}":/build ${GIT_VOLUME_OPTION} \
  -v "$PWD":/source -e NUM_CPUS --cap-add SYS_PTRACE --cap-add NET_RAW --cap-add NET_ADMIN "${IMAGE_NAME}":"${IMAGE_ID}" \
  /bin/bash -lc "groupadd --gid $(id -g) -f envoygroup && useradd -o --uid $(id -u) --gid $(id -g) --no-create-home \
  --home-dir /source envoybuild && usermod -a -G pcap envoybuild && su envoybuild -c \"cd source && $*\""

I've run into this issue before, maybe it's because of where the envoy docker build is? I have the same not a git repository error, and running just ./ci/do_ci.sh bazel.dev gives me a permission denied error like above.

Try
export ENVOY_DOCKER_BUILD_DIR=~/tmp/envoy-docker-build/

and then running
./ci/run_envoy_docker.sh './ci/do_ci.sh bazel.dev'

That worked for me.

[zqzzq]

@asraa Very thanks! That worked for me, too. Now I have built it successfully. Closing this.
