We also host native packages for Linux on Package Cloud and Windows packages can be installed via Chocolatey (4.0.0 onwards only).

Building EventStoreDB

EventStoreDB is written in a mixture of C# and JavaScript. It can run on Windows, Linux and macOS (using Docker) using the .NET Core runtime.

Windows / Linux

Prerequisites

.NET Core SDK 6.0

Build EventStoreDB

Once you've installed the prerequisites for your system, you can launch a Release build of EventStore as follows:

dotnet build -c Release src

The build scripts: build.sh and build.ps1 are also available for Linux and Windows respectively to simplify the build process.

To start a single node, you can then run:

dotnet ./src/EventStore.ClusterNode/bin/x64/Release/net6.0/EventStore.ClusterNode.dll --dev --db ./tmp/data --index ./tmp/index --log ./tmp/log

Running the tests

You can launch the tests as follows:

dotnet test src/EventStore.sln

Build EventStoreDB Docker image

You can also build a Docker image by running the command:

docker build --tag myeventstore . \
--build-arg CONTAINER_RUNTIME={container-runtime}
--build-arg RUNTIME={runtime}

For instance:

docker build --tag myeventstore . \
--build-arg CONTAINER_RUNTIME=bullseye-slim \
--build-arg RUNTIME=linux-x64

Note: Because of the Docker issue, if you're building a Docker image on Windows, you may need to set the DOCKER_BUILDKIT=0 environment variable. For instance, running in PowerShell:

$env:DOCKER_BUILDKIT=0; docker build --tag myeventstore . `
--build-arg CONTAINER_RUNTIME=bullseye-slim `
--build-arg RUNTIME=linux-x64

Currently we support following configurations:

Bullseye slim:

CONTAINER_RUNTIME=bullseye-slim
RUNTIME=linux-x64

Focal:

CONTAINER_RUNTIME=focal
RUNTIME=linux-x64

Alpine:

CONTAINER_RUNTIME=alpine
RUNTIME=alpine-x64

You can verify the built image by running:

docker run --rm myeventstore --insecure --what-if

Building the EventStoreDB Clients

The client libraries are located in their own repositories, refer to their specific instructions.

gRPC clients:

TCP clients:

Note: the TCP protocol is being phased out.

Contributing

Development is done on the master branch. We attempt to do our best to ensure that the history remains clean and to do so, we generally ask contributors to squash their commits into a set or single logical commit.

If you want to switch to a particular release, you can check out the release branch for that particular release. For example:
git checkout release/oss-v22.10

Read more in the contribution guidelines.

Proto Changes

If you update the protos, continuous integration will fail. After ensuring the proto change is backwards compatible, please run ./protolock.sh commit at the root of this repository.
