Embedded Postgres Binaries

Introduction

This project provides lightweight bundles of PostgreSQL binaries with reduced size that are intended for testing purposes. It is a supporting project for the primary io.zonky.test:embedded-database-spring-test and io.zonky.test:embedded-postgres projects. However, with a little effort, the embedded binaries can also be integrated with other projects.

Provided features

• Lightweight bundles of PostgreSQL binaries with reduced size (~10MB)
• Embedded PostgreSQL 11+ binaries even for Linux platform
• Configurable version of PostgreSQL binaries

Projects using the embedded binaries

• zonkyio/embedded-database-spring-test (Java - Spring)
• zonkyio/embedded-postgres (Java)
• hgschmie/pg-embedded (Java)
• fergusstrange/embedded-postgres (Go)
• theseus-rs/postgresql-embedded (Rust)
• faokunega/pg-embed (Rust)
• leinelissen/embedded-postgres (NodeJS)

Postgres version

The version of the postgres binaries can be managed by importing embedded-postgres-binaries-bom in a required version in your dependency management section.

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>io.zonky.test.postgres</groupId>
            <artifactId>embedded-postgres-binaries-bom</artifactId>
            <version>16.0.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

A list of all available versions of postgres binaries is here: https://mvnrepository.com/artifact/io.zonky.test.postgres/embedded-postgres-binaries-bom

Supported architectures

By default, only dependencies for amd64 architecture, in the io.zonky.test:embedded-database-spring-test and io.zonky.test:embedded-postgres projects, are included. Support for other architectures can be enabled by adding the corresponding Maven dependencies as shown in the example below.

<dependency>
    <groupId>io.zonky.test.postgres</groupId>
    <artifactId>embedded-postgres-binaries-linux-i386</artifactId>
    <scope>test</scope>
</dependency>

Supported platforms: Darwin, Windows, Linux, Alpine Linux
Supported architectures: amd64, i386, arm32v6, arm32v7, arm64v8, ppc64le

Note that not all architectures are supported by all platforms, you can find an exhaustive list of all available artifacts here: https://mvnrepository.com/artifact/io.zonky.test.postgres

Building from Source

The project uses a Gradle-based build system. In the instructions below, ./gradlew is invoked from the root of the source tree and serves as a cross-platform, self-contained bootstrap mechanism for the build.

Prerequisites

Git, JDK 6 or later and Docker

Be sure that your JAVA_HOME environment variable points to the jdk1.6.0 folder extracted from the JDK download.

Compiling non-native architectures rely on emulation, so it is necessary to register qemu-*-static executables:

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Note that the complete build of all supported architectures is now supported only on Linux platform.

Check out sources

git clone git@github.com:zonkyio/embedded-postgres-binaries.git

Make complete build

Builds all supported artifacts for all supported platforms and architectures, and also builds a BOM to control the versions of postgres binaries.

./gradlew clean install --parallel -Pversion=10.6.0 -PpgVersion=10.6

Note that the complete build can take a very long time, even a few hours, depending on the performance of the machine on which the build is running.

Make partial build

Builds only binaries for a specified platform/submodule.

./gradlew clean :repacked-platforms:install -Pversion=10.6.0 -PpgVersion=10.6

Build only a single binary

Builds only a single binary for a specified platform and architecture.

./gradlew clean install -Pversion=10.6.0 -PpgVersion=10.6 -ParchName=arm64v8 -PdistName=alpine

It is also possible to include the PostGIS extension by passing the postgisVersion parameter, e.g. -PpostgisVersion=2.5.2. Note that this option is not (yet) available for Windows and Mac OS platforms.

Optional parameters:

• postgisVersion
  • default value: unset
  • supported values: a postgis version number (only 2.5.2+, 2.4.7+, 2.3.9+ versions are supported)
• archName
  • default value: amd64
  • supported values: amd64, i386, arm32v6, arm32v7, arm64v8, ppc64le
• distName
  • default value: debian-like distribution
  • supported values: the default value or alpine
• dockerImage
  • default value: resolved based on the platform
  • supported values: any supported docker image
• qemuPath
  • default value: executables are resolved from /usr/bin directory or downloaded from https://github.com/multiarch/qemu-user-static/releases/download/v2.12.0
  • supported values: a path to a directory containing qemu executables
