Rust source-to-image

This repository contains the source for building Rust applications as reproducible Docker images using source-to-image.

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

Installation

You will either need to pre-install docker-squash that is used for squashing docker layers or you can skip squashing with export SKIP_SQUASH=1.

To prepare the builder image:

$ git clone https://github.com/openshift-s2i/s2i-rust.git
$ cd s2i-rust
$ make build

Use

Use the s2i tool to build the final image that contains your application code:

$ s2i build ./examples/test-app/ openshift/rust-120-centos7 rust-test-app

• ./1.20/test/test-app/ is the top directory of your source code.
• openshift/rust-120-centos7 is the name of the builder image created by make build above.
• rust-test-app is the name of the new image that contains your application code.

Finally, run the image:

$ docker run rust-test-app

Environment variables

Application developers can use the following environment variables to configure the runtime behavior of this image:
