|
||
<p>This explains the requirements to use youki as a low-level container runtime, or to depend once of its crates as dependency for your own project.</p>
|
||
<p>Youki currently only supports Linux Platform, and to use it on other platform you will need to use some kind of virtualization.</p>
|
||
<p>Also note that youki currently only supports and expects systemd as init system, and would not work on other systems. There is currently work on-going to put systemd dependent features behind a feature flag, but till then you will need a systemd enabled system to work with youki.</p>

<h3 id="runtime-requirements"><a class="header" href="#runtime-requirements">Runtime requirements</a></h3>
|
||
<p>The static binary (musl) builds of youki have no additional runtime requirements. Otherwise you need to install the runtime requirements using your distribution’s package manager:</p>

<pre><code class="language-console"># curl -sSfL https://github.com/youki-dev/youki/releases/download/v0.5.7/youki-0.5.7-$(uname -m)-musl.tar.gz | tar -xzvC /usr/bin/ youki

<!--youki release end-->
|
||
<h3 id="running-youki"><a class="header" href="#running-youki">Running youki</a></h3>
|
||
<p>You can use youki by itself to start and run containers, but it can be a little tedious, as it is a low-level container runtime. You can use a High-level container runtime, with its runtime set to youki, so that it will be easier to use.</p>
|
||
<p>This documentation uses Docker in its examples, which can be installed from <a href="https://docs.docker.com/engine/install">here</a>.
|
||
After installing Docker, configure youki as a Docker runtime as follows:</p>
|
||
<pre><code class="language-console">sudo cat > /etc/docker/daemon.json <<EOF
|
||
{
|
||
"runtimes": {
|
||
"youki": {
|
||
"path": "/usr/bin/youki"
|
||
}
|
||
}
|
||
}
|
||
EOF
|
||
|
||
sudo systemctl reload docker
|
||
</code></pre>
|
||
<p>Once configured, you can run a container using youki like this:</p>
|
||
<pre><code class="language-console">docker run --rm --runtime youki hello-world
|
||
</code></pre>
|
||

|
||
<h3 id="build-requirements"><a class="header" href="#build-requirements">Build Requirements</a></h3>
|
||
<p>As youki is written in Rust, you will need to install and setup Rust toolchain to compile it. The instructions for that can be found on Rust’s official site <a href="https://www.rust-lang.org/tools/install">here</a>.
|
||
If you installed it using rustup, the correct compiler version will be setup automatically from <code>rust-toolchain.toml</code> in the repo root.</p>
|
||
<h3 id="build-with-cross-rs"><a class="header" href="#build-with-cross-rs">Build with cross-rs</a></h3>
|
||
<p>You can compile youki using <a href="https://github.com/cross-rs/cross">cross-rs</a>, which provides:</p>
|
||
<ul>
|
||
<li>Seamless compilation for different architectures (see <code>Cross.toml</code> in the repo root for the list of supported targets)</li>
|
||
<li>No build time dependencies (compilation runs in a container)</li>
|
||
<li>No runtime dependencies when building static binaries (musl targets)</li>
|
||
</ul>
|
||
<p>The only build dependency is <a href="https://github.com/cross-rs/cross?tab=readme-ov-file#installation">cross-rs</a> and its <a href="https://github.com/cross-rs/cross?tab=readme-ov-file#dependencies">dependencies</a> (rustup and docker or podman).</p>

<h3 id="getting-the-source"><a class="header" href="#getting-the-source">Getting the source</a></h3>
|
||
<p>Currently youki can only be installed from the source code itself, so you will need to clone the youki GitHub repository to get the source code for using it as a runtime. If you are using any crates of youki as dependency you need to do this step, as Cargo will automatically clone the repository for you.</p>
|
||
<p>To clone the repository, run</p>
|
||
<pre><code class="language-console">git clone https://github.com/youki-dev/youki.git
|
||
</code></pre>
|
||
<p>This will create a directory named youki in the directory you ran the command in. This youki directory will be referred to as root directory throughout the documentation.</p>

|
||
<p>Once you have cloned the source, you can build it with <a href="https://github.com/casey/just#installation">just</a> :</p>
|
||
<pre><code class="language-console"># go into the cloned directory
|
||
cd youki
|
||
just youki-dev # or youki-release
|
||
./youki -h # get information about youki command
|
||
</code></pre>
|
||
<p>This will build the youki binary, and put it at the root level of the cloned directory, that is in the youki/ .</p>

<h3 id="using-sub-crates-as-dependency"><a class="header" href="#using-sub-crates-as-dependency">Using sub-crates as dependency</a></h3>
|
||
<p>To use any of the sub-crate as a dependency in your own project, you can specify the dependency as follows,</p>
|
||
<pre><code class="language-toml">[dependencies]
|
||
...
|
||
liboci-cli = { git = "https://github.com/youki-dev/youki.git" }
|
||
...
|
||
</code></pre>
|
||
<p>Here we use <code>liboci-cli</code> as an example, which can be replaced by the sub-crate that you need.</p>
|
||
<p>Then you can use it in your source as</p>
|
||
<pre><code>use liboci_cli::{...}
|

</code></pre>

<h3 id="using-vagrant-to-run-youki-on-non-linux-platform"><a class="header" href="#using-vagrant-to-run-youki-on-non-linux-platform">Using Vagrant to run youki on non-Linux Platform</a></h3>
|
||
<p>As explained before, youki only support Linux, and to build/use it on non-Linux Platforms, you will need to use some kind of virtualization. The repo provides a Vagrantfile to do the required VM setup using Vagrant, which can be installed from <a href="https://www.vagrantup.com/docs/installation">here</a>.</p>
|
||
<p>Once installed and setup, you can run vagrant commands in the cloned directory to run youki inside the VM created by vagrant :</p>
|
||
<pre><code class="language-console"># in the youki directory
|
||
|
||
# for rootless mode, which is default
|
||
vagrant up default
|
||
vagrant ssh default
|
||
|
||
# or if you want to develop in rootful mode
|
||
vagrant up rootful
|
||
vagrant ssh rootful
|
||
|
||
# in virtual machine
|
||
cd youki
|
||
just youki-dev # or youki-release
|

</code></pre>
