Wire server

This repository contains the source code for the Wire server. It contains all libraries and services necessary to run Wire.

For documentation on how to self host your own Wire-Server see this section. Federation is on our long term roadmap.

See more in “Open sourcing Wire server code”.

Architecture Overview

The following diagram gives a high-level outline of the (deployment) architecture of the components that make up a Wire Server as well as the main internal and external dependencies between components.


Communication between internal components is currently not guarded by dedicated authentication or encryption and is assumed to be confined to a private network.

Development setup

How to build wire-server binaries

There are two options:

1. Compile sources natively.

This requires a range of dependencies that depend on your platform/OS, such as:

  • Haskell & Rust compiler and package managers
  • Some package dependencies (libsodium, openssl, protobuf, icu, geoip, snappy, cryptobox-c, …) that depend on your platform/OS

See docs/developer/dependencies.md for details.

Once all dependencies are set up, the following should succeed:

# build all haskell services
# build one haskell service, e.g. brig:
cd services/brig && make

The default make target (fast) compiles unoptimized (faster compilation time, slower binaries), which should be fine for development purposes. Use make install to get optimized binaries.

For building nginz, see services/nginz/README.md

2. Use docker

If you don’t wish to build all docker images from scratch (e.g. the alpine-builder takes a very long time), ready-built images can be downloaded from here.

If you wish to build your own docker images, you need docker version >= 17.05 and make. Then,

# optionally:
# make docker-builder # if you don't run this, it pulls the alpine-builder image from quay.io
make docker-deps docker-intermediate docker-services

# subsequent times, after changing code, if you wish to re-create docker images, it's sufficient to
make docker-intermediate docker-services

will, eventually, have built a range of docker images. Make sure to give Docker enough RAM; if you see make: *** [builder] Error 137, it might be a sign that the build ran out of memory. You can also mix and match – e.g. pull the alpine-builder image and build the rest locally.

See the Makefiles and Dockerfiles, as well as build/alpine/README.md for details.

How to run integration tests

Integration tests require all of the haskell services (brig, galley, cannon, gundeck, proxy, cargohold, spar) to be correctly configured and running, before being able to execute e.g. the brig-integration binary. The test for brig also starts nginz, so make sure it has been built before. These services require most of the deployment dependencies as seen in the architecture diagram to also be available:

  • Required internal dependencies:
    • cassandra (with the correct schema)
    • elasticsearch (with the correct schema)
    • redis
  • Required external dependencies are the following configured AWS services (or “fake” replacements providing the same API):
    • SES
    • SQS
    • SNS
    • S3
    • DynamoDB
  • Required additional software:
    • netcat (in order to allow the services being tested to talk to the dependencies above)

Setting up these real, but in-memory internal and “fake” external dependencies is done easiest using docker-compose. Run the following in a separate terminal (it will block that terminal, C-c to shut all these docker images down again):


Then, to run all integration tests:

make integration

Or, alternatively, make on the top-level directory (to produce all the service’s binaries) followed by e.g cd services/brig && make integration to run one service’s integration tests only.

when you need more fine-grained control over your build-test loops

You can use $WIRE_STACK_OPTIONS to pass arguments to stack through the Makefiles. This is useful to e.g. pass arguments to a unit test suite or temporarily disable -Werror without the risk of accidentally committing anything, like this:

WIRE_STACK_OPTIONS='--ghc-options=-Wwarn --test-arguments="--quickcheck-tests=19919 --quickcheck-replay=651712"' make -C services/gundeck

Integration tests are run via /services/integration.sh, which does not know about stack or $WIRE_STACK_OPTIONS. Here you can use $WIRE_INTEGRATION_TEST_OPTIONS:

cd services/spar
WIRE_INTEGRATION_TEST_OPTIONS="--match='POST /identity-providers'" make i

Alternatively, you can use tasty’s support for passing arguments vie shell variables directly. Or, in the case of spar, the hspec equivalent, which is less helpful at times.

How to install and run wire-server

You have two options:

  • Option 1. (recommended) Install wire-server on kubernetes using the configuration and instructions provided in wire-server-deploy. This is the best option to run it on a server and recommended if you want to self-host wire-server.
  • Option 2. Compile everything in this repo, then you can use the docker-compose based demo. This option is intended as a way to try out wire-server on your local development machine and is less suited when you want to install wire-server on a server.
