Goma server

Goma is a distributed compiler service for open-source project such as Chromium and Android. It's some kind of replacement of distcc+ccache.

This is reference implementation of server code to be used with Goma client.


The Goma server uses a backend service that implements the Remote Execution API to distribute compile requests across a collection of worker machines and to cache the results of compilations. The Remote Execution API is an open-source standard, with multiple service implementations. The Goma server has been tested with Google's Remote Build Execution service, but could use other service implementations with some minor tweaks to the service code.

To learn more about Remote Build Execution, which is currently an alpha service, you can view the whitelisted documentation by joining this group. If you would like to try using Goma with Remote Build Execution, you can follow these instructions. (note: you must join the documentation whitelist group to view the instructions).

How to build

Goma server can be built on Linux.

$ GO111MODULE=on go get

You will get the binary in $(go env GOPATH)/bin.

How to run

remoteexec_proxy is a single server that acts as proxy server between Goma client and Remote Execution API.

$ remoteexec_proxy --port $PORT \
   --platform-container-image "docker://...@sha256:..." \
   --remoteexec-addr $REMOTEEXEC_ADDR \
   --remote-instance-name $REMOTE_INSTANCE_NAME

for chromium, platform container image should be created with

Example Dockerfile

FROM ubuntu:16.04
ENV DEBIAN_FRONTEND noninteractive

ADD /tmp/
RUN base64 -d /tmp/ > /tmp/ \
  && \
  apt-get -y update \
  && \
  apt-get install -f -y build-essential gcc-4.8 g++-4.8 \
  && \
  bash /tmp/ --lib32 --no-prompt \
     --no-chromeos-fonts \
  && \
  rm -rf /var/lib/apt/lists/*

If Remote Execution API requires service account, specify service account JSON file for Remote Execution API by --service-account-json.

Running user is granted by default. If you need to allow other users, you need to specify them by --whitelisted-users.

Log messages will be output to stderr.

How to use

Install goma client. We provide prebuilt binary with cipd, which is available in depot_tools.

$ cipd install infra/goma/client/linux-amd64 -root ${HOME}/goma

or follow the build instructions to build your own local version of Goma client before running the server code, and install it in $HOME/goma.

Need to authenticate Goma client before use.

$ $HOME/goma/ login

Specify hostname in $GOMA_SERVER_HOST and port in $GOMA_SERVER_PORT, along with a few other environment flags.

$ export GOMA_SERVER_HOST='host-of-remoteexec_proxy-running'
$ export GOMA_SERVER_PORT='port-of-remoteexec_proxy-running'
$ export GOMA_USE_SSL=false

For example, if you are running remoteexec_proxy locally with --port 5050, use:

$ export GOMA_SERVER_HOST=localhost
$ export GOMA_SERVER_PORT=5050

Finally, start Goma client:

$ $HOME/goma/ ensure_start

and in chromium tree.

$ rm -f out/Release/obj/base/base/base64.o
$ GOMA_USE_LOCAL=false autoninja -C out/Release obj/base/base/base64.o
