Developers can take advantage of the customization options available with RoadRunner to create a server optimized for their particular project.
This can include:
- Adding custom plugins.
- Forking existing ones to make changes.
- Building a lightweight server with only the necessary plugins.
We created a tool called Velox that lets developers build a RoadRunner server binary. It uses a configuration file to determine which plugins and repositories are required for building a RoadRunner server binary.
The configuration file is written in TOML format and contains a list of repositories to add to the build. For each repository, you can specify the owner and version. You can also add private repositories from GitHub or Gitlab, and authenticate with access tokens.
{% hint style="info" %} To download all the required plugins for RoadRunner, you need a GitHub token. If you try to download plugins without a token, anonymous access is limited to 50 requests per hour. You can read more about these limits on the Rate limits for GitHub Apps page. {% endhint %}
Here is an example of a configuration file:

{% hint style="info" %} You can find the latest version of the example configuration file in the official repository. {% endhint %}
{% hint style="warning" %}
When using official plugins for RoadRunner, it is recommended avoid using the master branch as it may contain
unstable code. Instead, use tags with the same major version (e.g., logger:v4.x.x + amqp:v4.x.x, but
not logger:v4.0.0 + amqp:v3.0.5). Please note that the currently supported plugin version is v5.x.x, and the
supported RoadRunner version is >=v2024.2.x.
Failure to follow these guidelines may result in compatibility issues and other problems. Please pay close attention to your configuration file to ensure proper use of plugins. {% endhint %}
You can use environment variables in the configuration file. This is useful when you want to keep the configuration file
in the repository, but you don't want to expose your tokens or just want to pass them as arguments to the vx command.
Here is the list of environment variables from the example above:
| Variable | Description |
|---|---|
${GL_TOKEN} |
GitLab token. |
${RT_TOKEN} |
GitHub token. |
${VERSION} |
RR version to write into the binary (will be shown with ./rr --version). |
${TIME} |
Build time (will be shown with ./rr --version). |
{% hint style="info" %}
Keep in mind to set the latest stable version in the ${VERSION} env variable. You may also use ${TIME} env
variable to write the build time in the output binary.
{% endhint %}
| Option | Description |
|---|---|
| ref | Tag, commit hash or branch name. |
| owner | Repository owner (might be the user or organization). |
| repository | Repository name. |
| folder | If the plugin is in some folder in your repository, you may specify it via this configuration option. For example: cache = { ref = "v1.6.18", owner = "darkweak", repository = "souin", folder="plugins/roadrunner" } |
| replace | Go.mod replace directive. |
{% hint style="info" %}
To replace the module with the local copy or some remote module, use the following velox.toml configuration:
{% code title="velox.toml" %}
your_module = { ref = "master", owner = "owner", repository = "repo", replace="github.com/owner2/repo2" }{% endcode %}
Or with your local copy:
{% code title="velox.toml" %}
your_module = { ref = "master", owner = "owner", repository = "repo", replace="../path/to/a/local/dir" }{% endcode %}
{% endhint %}
- Make sure the
ssh-agentis running and the ssh key has been added: link - Exclude your organization package prefix from the Go environment variables:
{% code %}
go env -w GOPRIVATE="github.com/<company_name>/*,gitlab.com/<company_name>/*"
go env -w GONOSUMDB="github.com/<company_name>/*,gitlab.com/<company_name>/*"{% endcode %}
{% tabs %}
{% tab title="Docker" %}
Using the Docker image simplifies the build process by automatically building the RoadRunner binary and storing it in
the /usr/bin/ folder. This eliminates the need to install Golang or other dependencies on your computer. Once the
build is complete, Docker will automatically start the RoadRunner server.
Here is an example of Dockerfile:
{% code title="Dockerfile" %}
# https://docs.docker.com/buildx/working-with-buildx/
# TARGETPLATFORM if not empty OR linux/amd64 by default
FROM --platform=${TARGETPLATFORM:-linux/amd64} ghcr.io/roadrunner-server/velox:latest as velox
# app version and build date must be passed during image building (version without any prefix).
# e.g.: `docker build --build-arg "APP_VERSION=1.2.3" --build-arg "BUILD_TIME=$(date +%FT%T%z)" .`
ARG APP_VERSION="undefined"
ARG BUILD_TIME="undefined"
# copy your configuration into the docker
COPY velox.toml .
# we don't need CGO
ENV CGO_ENABLED=0
# RUN build
RUN vx build -c velox.toml -o /usr/bin/
FROM --platform=${TARGETPLATFORM:-linux/amd64} php:8.3-cli
# copy required files from builder image
COPY --from=velox /usr/bin/rr /usr/bin/rr
# use roadrunner binary as image entrypoint
CMD ["/usr/bin/rr"]{% endcode %}
{% endtab %}
{% tab title="Go" %}
You can use the go install command to download Velox.
{% hint style="warning" %} To download Velox and build an application server you need Golang 1.22+ on you local server. {% endhint %}
{% code title="go install" %}
go install github.com/roadrunner-server/velox/v2024/cmd/vx@latest{% endcode %}
After the binary has been downloaded, you can build the application server:
{% code title="vx build" %}
vx build -c velox.toml -o ~/Downloads{% endcode %}
| Option | Description |
|---|---|
-c |
path to the configuration |
-o |
path where to put the RR binary |
{% endtab %}
{% tab title="Downloading Binary" %}
To build the application server, you need to download Velox binary
the GitHub releases page and unpack it to your PATH.
{% hint style="warning" %} To build an application server you need Golang 1.22+ on you local server. {% endhint %}
After the binary has been downloaded, you can build the application server:
{% code title="vx build" %}
vx build -c velox.toml -o ~/Downloads{% endcode %}
| Option | Description |
|---|---|
-c |
path to the configuration |
-o |
path where to put the RR binary |
