+# drone-rsync-ssh
+
+A Dockerfile for rsync+ssh deploys using [Drone](https://drone.io/).
+
+* In Drone, add repository secrets for `ssh_private_key` and `ssh_host_key`
+* In your `.drone.yml`, run `drone-ssh-keys` to inject SSH secrets into `~/.ssh`
+
+## Sample .drone.yml
+
+Here's a sample `.drone.yml` that injects the SSH keys, rsyncs files to a host,
+then triggers a command on the host.
+
+    pipeline:
+      deploy:
+        image: images.abackstrom.com/rsync-ssh
+        secrets: [ ssh_private_key, ssh_host_key ]
+        commands:
+          - drone-ssh-keys
+          - rsync -Chrz -e ssh ./public user@host:/var/www/html
+          - ssh user@host 'sudo systemctl reload nginx'
+
+## Building the image
+
+    make image IMAGE_NAME=your_name_here
+
