Rust Cloud Native Buildpack

docker.io/paketocommunity/rust

The Rust Cloud Native Buildpack provides a set of collaborating buildpacks that enable the building of a Rust-based application.

Included Buildpacks

• paketo-community/rustup
• paketo-community/rust-dist
• paketo-community/cargo
• paketo-buildpacks/procfile

tl;dr

You can build your app with two steps:

1. Run pack build <image-name> -b docker.io/paketocommunity/rust. An image will be generated that you can run.
2. Run the image with docker run -it <image-name>.

By default, the Rust buildpack will add process types for all of the binary projects in your workspace. You may optionally add a Procfile though if you need to customize the start command for your container.

What's Included

A Meta Buildpack

Included in this repo is a buildpack.toml that defines the Rust meta buildpack. It allows you to reference all of the Rust related CNBs in one convenient way & know that the order is set correctly.

This is available through a pre-built docker image on Docker Hub.

To use: pack build <image-name> -b docker.io/paketocommunity/rust

A Builder

In this repo is a sample example-builder.toml that you can use to create your own builder. We do not publish a builder, so if you'd like to use this route you must first create the builder.

To create the builder, just run pack builder create <published-to>/rust-builder --config example-builder.toml. For example, pack builder create paketocommunity/rust-builder --config example-builder.toml.

You can then build an app with it using pack build <image-name> --builder <published-to>/rust-builder.

The builder is configure to use the base build and run images, which is a reasonable mix of size and functionality. You may change the build and run images to use the full stack, which has a lot more libraries and tools installed but is quite a bit larger, or you can use the tiny build and run images which presents a very small container but doesn't even contain a shell, which can make debugging difficult.

To switch, swap the stack that you'd like to use in the builder file.

Example full stack:

[stack]
  id = "io.buildpacks.stacks.jammy"
  build-image = "docker.io/paketobuildpacks/build-jammy-base:latest"
  run-image = "docker.io/paketobuildpacks/run-jammy-base:latest"

Example tiny stack:

[stack]
  id = "io.buildpacks.stacks.jammy.tiny"
  build-image = "docker.io/paketobuildpacks/build-jammy-tiny"
  run-image = "docker.io/paketobuildpacks/run-jammy-tiny"

Tips

• When building for the Paketo Tiny stack, you must build with the target set to x86_64-unknown-linux-musl. This is because if you build with the glibc target, you will end up with a dependency for the libgcc_s.so.1 library that does not exist on the Paketo Tiny run image. If we target musl instead, you'll get a binary that is statically compiled against musl and does not have this requirement, thus it will run on the Tiny stack.

  When you run with the Tiny stack, the buildpacks will detect this and automatically adjust. This includes installing the additional target to cross-compile and modifying cargo commands cross-compile using the musl target.

• By default, the Rust buildpack will install tini, which is a very small process manager that handles the PID1 responsibilities (it's also the same running docker run --init), into your application image. Because your application will run as PID1, this ensures that your application will properly handle signals. If you are running your image with Docker, this is what makes CTRL+C function correctly. If you're running on Kubernetes, this is what makes graceful termination work correctly.

  It is generally recommended that you keep tini installed. It's extremely low-overhead. That said, if you really, really know what you're doing and your application is properly handling signals and reaping child processes then you may set $BP_CARGO_TINI_DISABLED=true and the buildpacks will skip installing tini..

• What's the difference between using a builder and using the composite buildpack (i.e. docker.io/paketocommunity/rust)? There's not a lot of difference, so feel free to use which one is more convenient for your use cases. The composite buildpack is published to Docker Hub so it's often easier to get started using it. We are not publishing a builder image at the moment, so you need to build that on your own. The builder does offer some additional customization options though. Plus, you can set a default builder with pack, so if you're building many different applications it can reduce the amount of flags you need to send to pack build. You do not need to use both the builder and composite buildpack.

• Can I specify multiple processes in my Procfile? Yes! To make this work, just add more lines to Procfile. One of the lines needs to be named web, which is the expected name for the default process. Alternatively, you may use different names but pass the --default-process argument to pack build to indicate the default process name in your Procfile. It is highly recommended that you have a default process. See here for more details on multiple process containers.

• Can I pass arguments to my application? Yes, you just append them to the end of your docker run command. See here for an example.

• How do I run a non-default process from my Procfile? Pass --entrypoint <process name> to docker run. See here for an example.

• How do I launch a shell in my container to debug? There are two ways to do this. First, docker run --rm --entrypoint launcher -it <image-name> bash. The first will set up the shell with the standard environment, the same as what your application will get when it launches. Second, docker run --rm --entrypoint bash -it <image-name>. The second will give you a blank environment without any buildpack specific environment variables set.

rust's Issues

Add support for `upx`

upx is a tool for compressing binary executables. It has some excellent compression ratios and very low runtime overhead. It would be helpful with Rust binaries. We should add support.

This also needs to be supported in Cargo: paketo-community/cargo#238

Mark step in tldr as optional

This step is not needed to get the application to run:
Add a [Procfile](https://paketo.io/docs/howto/configuration/#procfiles) with the command that should be executed to run your app.

Would mark it as optional or put it somewhere below for detailed setup but not in tldr section.

Dockerized rust applications not receiving signals from command line

I packaged a rocket server with this rust buildpack but then encountered a problem of not being able to kill it via command line.
This problem is also true for a rocket server with a standard Dockerfile.
But adding the tini command inbetween solves the signal handling problem here.
The tini buildpack could be added to improve the signal handling (eg. CTRL+C) for dockerized servers in rust.

Buildpacks produce quite big image

Hi,

I'm comparing image I'm building directly with Docker file like such with Rust static executable inside it:

FROM scratch
COPY target/x86_64-unknown-linux-gnu/release/function /function
CMD [ "/function" ]

where I'm getting as output - image of about 14MB in size:

$ podman image ls | grep sample
localhost/sample                                                   latest         9f76d50aaa01  8 minutes ago  13.9 MB

and layers:

$ podman history sample
ID            CREATED        CREATED BY                                     SIZE        COMMENT
8144b031a549  8 minutes ago  /bin/sh -c #(nop) CMD [ "/function" ]          0 B         FROM 8144b031a549
<missing>     8 minutes ago  /bin/sh -c #(nop) COPY file:3b28c741a95a71...  13.9 MB   

And then I have image for same Rust function produced via buildpacks - about 107MB:

$ podman image ls | grep buildpack-sample
localhost/buildpack-sample                                         latest         181d2f0215c3  43 years ago    107 MB

and layers in it:

$ podman history buildpack-sample
ID            CREATED       CREATED BY  SIZE        COMMENT

<missing>     43 years ago              3.07 kB     
<missing>     43 years ago              3.07 kB     
<missing>     43 years ago              65.5 MB     

What is the cause of such big difference? Any specific setting/config to tweak somewhere to make it smaller via buildpacks as well?

Wrong url for cargo-install in builder.toml

The builder process was filing because rust-cargo couldn't be found on the repository.
builder.toml defines

uri = "docker://paketocommunity/rust-cargo:0.0.6"

it should be

uri = "docker://paketocommunity/cargo-install:0.0.6"

draft-release isn't working after recent update

Investigate why draft-release isn't working: https://github.com/paketo-community/rust/runs/6084253653?check_suite_focus=true

Use Test Binary | Help Wanted

I would like to run integration tests for a library independently from my application bin. To do so I need it deployed to my cluster. Hence, I was interested in using rust-cnb to create test image from my library's rust test binary. Is this possible?

Add integration tests

We should add integration tests that test the overall functionality of the rust buildpack.

Rename to "rust" to better align with Paketo naming convention

The naming convention in Paketo is to name a top level family buildpack just the name of the language or framework (e.g. go, ruby, php, etc). We should change the name of this repository to align with that naming convention.

Exception: ERROR: failed to launch: determine start command: when there is no default process a command is required

Hi admin,

I have managed to run pack build northwind-rs -e SQLX_OFFLINE=true -b docker.io/paketocommunity/rust command to build up the docker image using buildpacks. My pack version is 0.18.0+git-e00ee4a.build-2328, and I run it on Windows 10 OS.

It could run successfully and I could have the Docker image with the name northwind-rs, but when I tried to run it by docker then it throws the exception ERROR: failed to launch: determine start command: when there is no default process a command is required.

Could you guys let me know how can we overcome this exception?

My sample code is at https://github.com/thangchung/northwind-rs

Getting hang around buildpacksio/lifecycle:cache.sbom layer

I'm on x86_64 architecture. Running podman on my box. Disk has enough space.

Anything to check or enable some extra debug somewhere to understand the cause?

Unable to launch after build

Hi,

I'm able to build the rust image using the paketobuildpacks/builder:full and --buildpack paketo-community/[email protected] but the container never starts. I tried to write my Procfile like that (among other tries) :

web: ROCKET_PORT=$PORT ROCKET_KEEP_ALIVE=0 ./layers/paketo-community_cargo/Cargo/bin/rust-buildpack-example-rocket

I've also tried ./workspace and all possible combinations. The code I'm trying to build is available here : https://github.com/emk/rust-buildpack-example-rocket

Do you know what I need to do to start the container after the build?

Thanks!

Alex

failed to build: Missing label

failed to build: invalid builder paketocommunity/rust: builder index.docker.io/paketocommunity/rust:latest missing label io.buildpacks.builder.metadata -- try recreating builder

New to this stuff, so not sure if this is the right place to start.

I get this error trying to use this builder with controlplane cli.

Any tips would be greatly appreciated

Unable to find process

Hey, I am trying out this rust buildpack, I followed the documentation and created a Builder image using example-builder.toml, and then I am running this command:

pack build docker.io/abc/rust-webserver-app -b docker.io/paketocommunity/rust -B docker.io/abc/rust-builder --network=host --trust-builder --publish

which is successfully creating an image but I see this in the command outpu:

===> EXPORTING
Adding 1/1 app layer(s)
Adding layer 'launcher'
Adding layer 'config'
Adding label 'io.buildpacks.lifecycle.metadata'
Adding label 'io.buildpacks.build.metadata'
Adding label 'io.buildpacks.project.metadata'
no default process type

and when I am trying to docker run the built image, its erroring out with this:

ERROR: failed to launch: determine start command: when there is no default process a command is required

Any ideas how I can solve this? I inspected the built image using pack inspect-image but I don't see any processes listed in the output. Also considering this is a composite buildpack, I had a brief look around and hoped that there would a process mentioned here: https://github.com/paketo-community/cargo/blob/main/scripts/build.sh but it isnt so.

Apologies if this is something silly, just starting out with buildpacks and a huge fan of the idea!

jam summarize no long works

Since rust-dist was moved off of packit and the buildpack.toml format changed in release v1.0.0, jam summarize no long plays nicely with the language family buildpack. Specifically, jam summarize fails in the create release workflow.. This is because there is some disconnect in the format of the buildpack.toml and what versions of packit expect since jam v0.14.1 and on.

The recourse here is either to roll back to an older version of packit/jam (the v0.14.0 or before). Eventually, a fix for this issue in packit should come out (there is an issue open for this already), but in order to get releases created with the current automation, rolling back might be necessary.

Move default branch from "master" to "main"

We should change out default branch to be "main". This will align us with the rest of the Paketo project.

Update builder workflows

The workflow that is updating the builder is a one-off workflow. This was done because at the time the standard pipeline-builder workflow for updating a builder was not capable of running in a repo that was both a composite buildpack and a builder. This has since been fixed and the standard workflow should be OK for both in the same repo.

In addition, we should remove the update-lifecycle workflow. This isn't needed because our builder is not specifying a lifecycle, it's using the default one provided by pack.

This issue is a reminder to move back to the standard workflows.

Update Package Dependency workflow failing

Update Package Dependency job is failing. It appears to be due to the Go 1.18 change. The workflow is selecting an old Go version. It needs to be bumped to 1.18.

Outdated docs info in the builder section

The builder section of README.md is outdated, the new syntax is:

pack builder create rust-builder --config builder.toml
