Development is done on themaster branch.We attempt to do our best to ensure that the history remains clean and to do so, commits are automatically squashed into a single logical commit when pull requests are merged.

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/v25.0

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

Prerequisites

• .NET SDK 8.0

Once you've installed the prerequisites for your system, you can launch aRelease build of KurrentDB as follows:

dotnet build -c Release src

The build scripts:build.sh andbuild.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/KurrentDB/bin/Release/net8.0/KurrentDB.dll --dev --db ./tmp/data --index ./tmp/index --log ./tmp/log

You can launch the tests as follows:

dotnet test src/KurrentDB.sln

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

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

For instance:

docker build --tag mykurrentdb . \--build-arg CONTAINER_RUNTIME=bookworm-slim \--build-arg RUNTIME=linux-x64

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

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

Currently, we support the following configurations:

1. Bookworm slim:

• CONTAINER_RUNTIME=bookworm-slim
• RUNTIME=linux-x64

2. Jammy:

• CONTAINER_RUNTIME=Jammy
• RUNTIME=linux-x64

3. Alpine:

• CONTAINER_RUNTIME=alpine
• RUNTIME=linux-musl-x64

You can verify the built image by running:

docker run --rm mykurrentdb --insecure --what-if
