Go Docker images

Build Status

This repository contains the source for creating a source-to-image builder image, which be used to create reproducible Docker images from your Go project’s source code. The resulting image can be run using Docker.

For more information about using these images with OpenShift, please see the official OpenShift Documentation.

Versions

Go versions currently supported are:

  • Go 1.4.3

  • Go 1.5.3

  • Go 1.6

The following operating system base images are supported:

  • CentOS 7

Installation

To build a Go builder image, execute:

$ git clone https://github.com/openshift-s2i/s2i-go.git
$ cd s2i-go
$ make build VERSION=1.4

Alternatively, you can pull the CentOS image from Docker Hub via:

$ docker pull openshift/go-14-centos7

Notice: By omitting the VERSION parameter, the build/test action will be performed on all the supported versions of Go.

Usage

There are several sample Go applications included with this repository. To build a simple Go test application using the standalone

$ s2i build https://github.com/openshift-s2i/s2i-go.git \
    --context-dir=1.4/test/test-app openshift/go-14-centos7 go-test-app

The resulting image can be executed using docker:

$ docker run --rm -p 8080:8080 go-test-app

Once the container is running, it should be accessible using:

$ curl 127.0.0.1:8080

Test

This repository also provides a test suite to check functionality of simple Go applications built on top of the s2i-go image. It can be executed simply by running the make test command:

$ cd s2i-go
$ make test VERSION=1.4

Notice: By omitting the VERSION parameter, the build/test action will be performed on all the supported versions of Go.

Repository organization

  • <go-version>: Dockerfile to build container images from.

    • <go-version>/test/test-app: Sample Go application used for tests.

  • hack/: Folder containing scripts which are responsible for the build and test actions performed by the Makefile.

  • s2i/: Build scripts which will be injected into the builder image and executed during application source code builds.

Image name structure

Structure: openshift/1-2-3

  1. Platform name (lowercase) - go

  2. Platform version(without dots) - 14

  3. Base builder image - centos7/rhel7

Examples: openshift/go-14-centos7, openshift/go-14-rhel7
