go get



This is a package with simple support for writing Drone plugins in Go.


Plugins are executable files run by Drone to customize the build lifecycle. Plugins receive input data from stdin (or arg[1]) and write the results to stdout

./slack-plugin <<EOF
    "repo" : {
        "owner": "foo",
        "name": "bar",
        "full_name": "foo/bar"
    "build" : {
        "number": 1
        "status": "success",
        "started_at": 1421029603,
        "finished_at": 1421029813,
        "head_commit" : {
            "sha": "9f2849d5",
            "ref": "refs/heads/master"
            "branch": "master",
            "message": "Update the Readme",
            "author": {
                "login": "johnsmith"
                "email": "",
    "job" : {
        "number": 1,
        "status": "success",
        "started_at": 1421029603,
        "finished_at": 1421029813,
        "exit_code": 0,
        "environment": { "GO_VERSION": "1.4" }
    "clone" : {
        "branch": "master",
        "remote": "git://",
        "dir": "/drone/src/",
        "ref": "refs/heads/master",
        "sha": "436b7a6e2abaddfd35740527353e78a227ddcb2c"
    "vargs": {
        "webhook_url": "",
        "username": "drone",
        "channel": "#dev"

Use this plugin package to retrieve and parse input parameters:

var repo = plugin.Repo{}
var build = plugin.Build{}
var slack = struct {
    URL      string `json:"webhook_url"`
    Username string `json:"username"`
    Channel  string `json:"channel"`

plugin.Param("repo", &repo)
plugin.Param("build", &build)
plugin.Param("vargs", &slack)

Note that your plugin configuration data (declared in the .drone.yml file) will be provided in the vargs section of the JSON input.

Shared Volumes

The repository clone directory (specified in the clone.dir input parameter) will be shared across all plugins as a container volume. This means that any files in your repository directory or subdirectories are accessible to plugins. This is useful for plugins that analyze or archive files, such as an S3 plugin.


Drone plugins are distributed as Docker images. We therefore recommend publishing your plugins to Docker Hub.

The ENTRYPOINT must be defined and must point to your executable file. The CMD section will be overridden by Drone and will be used to send the JSON encoded data in arg[1]. An example Dockerfile for your plugin might look like this:

# Docker image for Drone's git-clone plugin
#     docker build -t drone/drone-clone-git .

FROM library/golang:1.4

# copy the local src files to the container's workspace.
ADD . /go/src/

# build the git-clone plugin inside the container.
RUN go get && \
    go install

# run the git-clone plugin when the container starts
ENTRYPOINT ["/go/bin/drone-clone-git"]
