# drone-ssh
Drone plugin for executing remote ssh commands
[![Build Status](http://beta.drone.io/api/badges/drone-plugins/drone-ssh/status.svg)](http://beta.drone.io/drone-plugins/drone-ssh)
[![](https://badge.imagelayers.io/plugins/drone-ssh:latest.svg)](https://imagelayers.io/?images=plugins/drone-ssh:latest 'Get your own badge on imagelayers.io')
Drone plugin for executing commands on a remote host through SSH
## Usage
```
./drone-ssh <<EOF
{
"repo" : {
"owner": "foo",
"name": "bar",
"full_name": "foo/bar"
},
"build" : {
"number": 22,
"status": "success",
"started_at": 1421029603,
"finished_at": 1421029813,
"commit": "9f2849d5",
"branch": "master",
"message": "Update the Readme",
"author": "johnsmith",
"author_email": "john.smith@gmail.com"
},
"vargs": {
"host": "foo.com",
"user": "root",
"port": 22,
"commands": [
"echo hello",
"echo world"
]
}
}
EOF
```
## Docker
Build the Docker container using `make`:
```
make deps build docker
```
### Example
```sh
docker run -i plugins/drone-ssh <<EOF
{
"repo" : {
"owner": "foo",
"name": "bar",
"full_name": "foo/bar"
},
"build" : {
"number": 22,
"status": "success",
"started_at": 1421029603,
"finished_at": 1421029813,
"commit": "9f2849d5",
"branch": "master",
"message": "Update the Readme",
"author": "johnsmith",
"author_email": "john.smith@gmail.com"
},
"vargs": {
"host": "foo.com",
"user": "root",
"port": 22,
"commands": [
"echo hello",
"echo world"
]
}
}
EOF
```
