baur is an incremental task runner for monolithic Git
repositories.
It can be used in CI environments to build, check and test only applications
that changed in a commit.
Practical usage examples of baur can be found in the example repository.
Per application tasks are defined in a TOML configuration file. Each task specifies:
- a command to run,
- which inputs (files) affect the result of the task run
- and optionally outputs that are created when the command is run and where those artifacts are uploaded to.
When baur runs a task, it calculates a digest for the task inputs and stores it
in a PostgreSQL database.
On following runs, baur only runs tasks for which the inputs changed.
-
Running Tasks only for Changed Applications
Tasks define which inputs affect the result of the task execution.
baur can only runs tasks that have not been run before for the current set of inputs.
Inputs can be defined as glob file patterns, environment variables, as strings on the commandline, or as Go package queries. -
Artifact Upload
Artifacts can be uploaded to S3 buckets, to Docker registries or simply copied to another directory in the filesystem. -
Application Management
baur can be used as management tool in monorepositories to query basic information about applications and upload destinations for specific builds. -
Optimized for CI
baur is made to be run in CI environments and supports to output information in the easily-parseable CSV and JSON formats. -
Configuration File Includes
Tasks, Inputs and Output definitions that are shared between tasks can be defined in include configuration files. -
Templating
Templating can be used in configuration files.
The recommended way is to download the latest released version from the release
page.
Official releases are provided for Linux, macOS and Windows.
After downloading the release archive, extract the baur binary
(tar xJf baur-OS_ARCH-VERSION.tar.xz) and move it to your preferred location.
You can build and install the latest version from the main branch by running:
go install github.com/simplesurance/baur/v5/...@mainbaur uses a PostgreSQL database to record information about past task runs. The quickest way to setup a PostgreSQL for local testing is with docker:
docker run -p 127.0.0.1:5432:5432 -e POSTGRES_DB=baur -e POSTGRES_HOST_AUTH_METHOD=trust postgres:latestAfterwards you create your baur repository configuration file. In the root directory of your Git repository run:
baur init repoThe command will print instructions how to initialize your database and create your first application configuration file.
To show information about the available commands run:
baur --helpSome commands to start with are:
| command | action |
|---|---|
baur status |
List task in the repository with their build status |
baur run |
Run all tasks of all applications with pending builds, upload their artifacts and records the result |
baur ls runs all |
List recorded tasks |
baur show currency-service |
Show information about an application called currency-service |
baur ls inputs --digests shop.build |
List inputs with their digests of the build task of an application called shop |
baur run --help |
Show the usage information for the run command. |

baur follows Semantic Versioning for its command line
interface, configuration file format and database schema.
The APIs of the Go packages are excluded from the semantic versioning policy.
Their APIs may change at any time in a backward incompatible manner.
