+Drone 插件，可通过 SSH 在远程主机执行命令。使用方法和可用选项请参考[官方文档](http://plugins.drone.io/appleboy/drone-ssh/)。
+
+**注意：请将 Drone 的 image config 路径更新为 `appleboy/drone-ssh`。`plugins/ssh` 已不再维护。**
+

+
+<!-- 图片说明：SSH 命令执行演示动画，内容与原文一致 -->
+
+## 重大变更
+
+`v1.5.0`：将命令超时参数更改为 `Duration` 格式。设置示例如下：
+
+```diff
+pipeline:
+  scp:
+    image: ghcr.io/appleboy/drone-ssh
+    settings:
+      host:
+        - example1.com
+        - example2.com
+      username: ubuntu
+      password:
+        from_secret: ssh_password
+      port: 22
+-     command_timeout: 120
++     command_timeout: 2m
+      script:
+        - echo "Hello World"
+```
+
+## 构建或下载二进制文件
+
+可在[发布页面](https://github.com/appleboy/drone-ssh/releases)下载预编译的二进制文件，支持以下操作系统：
+
+- Windows amd64/386
+- Linux arm/amd64/386
+- macOS (Darwin) amd64/386
+
+如已安装 `Go`，可执行：
+
+```sh
+go install github.com/appleboy/drone-ssh@latest
+```
+
+或使用以下命令自行构建二进制文件：
+
+```sh
+export GOOS=linux
+export GOARCH=amd64
+export CGO_ENABLED=0
+export GO111MODULE=on
+
+go test -cover ./...
+
+go build -v -a -tags netgo -o release/linux/amd64/drone-ssh .
+```
+
+## Docker
+
+可使用以下命令构建 Docker 镜像：
+
+```sh
+make docker
+```
+
+## 使用方法
+
+在工作目录下执行：
+
+```sh
+docker run --rm \
+  -e PLUGIN_HOST=foo.com \
+  -e PLUGIN_USERNAME=root \
+  -e PLUGIN_KEY="$(cat ${HOME}/.ssh/id_rsa)" \
+  -e PLUGIN_SCRIPT=whoami \
+  -v $(pwd):$(pwd) \
+  -w $(pwd) \
+  ghcr.io/appleboy/drone-ssh
+```
+
+## 通过文件路径挂载密钥
+
+请确保已在项目设置中启用 `trusted` 模式（适用于 [drone 0.8 版本](https://0-8-0.docs.drone.io/)）。
+
+![trusted mode](./images/trust.png)
+
+<!-- 图片说明：Drone 项目 trusted 模式设置界面 -->
+
+在 `.drone.yml` 配置文件的 `volumes` 部分挂载私钥：
+
+```diff
+pipeline:
+  ssh:
+    image: ghcr.io/appleboy/drone-ssh
+    host: xxxxx.com
+    username: deploy
++   volumes:
++     - /root/drone_rsa:/root/ssh/drone_rsa
+    key_path: /root/ssh/drone_rsa
+    script:
+      - echo "test ssh"
+```
+
+详情请参考 [issue comment](https://github.com/appleboy/drone-ssh/issues/51#issuecomment-336732928)。
+
+## 配置说明
+
+更多示例和完整配置选项请参考 [DOCS.md](./DOCS.md)
+
+配置选项来源如下：
+
+0. 内置 drone-ssh 默认值。详见 [main.go CLI Flags](https://github.com/appleboy/drone-ssh/blob/6d9d6acc6aef1f9166118c6ba8bd214d3a582bdb/main.go#L39)。
+1. 由 `PLUGIN_ENV_FILE` 环境变量指定的 dotenv 文件。
+2. `.drone.yml` Drone 配置文件。
+
+后面的来源会覆盖前面的设置，例如 `.env` 文件中的 `PORT` 会覆盖 main.go 的默认值。

+
+## 以檔案路徑掛載金鑰
+
+請確認已於專案設定中啟用 `trusted` 模式（適用於 [drone 0.8 版本](https://0-8-0.docs.drone.io/)）。
+
+![trusted mode](./images/trust.png)

+    image: ghcr.io/appleboy/drone-ssh
+    host: xxxxx.com
+    username: deploy
