Dune binaries distribution

This is a webpage for dune binaries distribution of Dune developer Preview. The page is automatically generated from file metadata.json. Apart from the YAML part, the code is written in OCaml.

The GitHub Actions pipeline regularly creates commit on the main branch where it:

• updates the content of metadata.json
• updates the content of index.html
• generates new artifacts and pushes them to their SSH storage using RClone

The web page is deployed on dune.ci.dev.

⌛ The pipeline is triggered every day at 01:00 UTC.

Installation & configuration

Requirement

You need to have opam available to install and build the project.

Install

The OCaml code is stored in the sandworm directory. Install the dependencies with the following commands:

$ cd sandworm/
$ opam install . --deps-only --with-dev-setup

Please note that --with-dev-setup should only be used for a development purpose.

Configure

The configuration is in sandworm/bin/config.ml file. When running in the pipeline, the sandworm binary is generated before its execution. As a result, the path taken is the root of this repository. If you want to run it locally, make sure the files artifacts and rclone.conf are available in the directory where sandworm binary is executed.

The export relies on an SSH key to the server. If you want to run your own tests, you need to have a server available by SSH with an SSH key. Then, you have to create a rclone.conf file as follows:

[dune-binary-distribution]
type = sftp
user = <username>
host = <replace.myhost.com>
key_file = </path/to/your/ssh/private/key>
shell_type = unix

If you don't have a /dune directory on your server, you might want to change the s3_bucket_ref variable. It could be:

let s3_bucket_ref = "dune-binary-distribution:/path/to/your/server/dir"

Tip

For our use case, the RClone configuration works with SFTP but, it is compatible with any RClone provider.

Running

Now your setup is ready, you can execute this list of commands to generate or update the files:

$ cd sandworm
$ dune build
$ cd ../
$ ls
artifacts rclone.conf
$ ./sandworm/_build/install/default/bin/sandworm

Deploying

The deployment are automatically done through GitHub Actions. No need to add extra work to deploy it.
