+### Using Craft Copy in Docker environments
+
+You may want to run Craft Copy with in a Docker container. You will need the following installed inside the container: 
+
+ - mysqldump
+ - mysql (client)
+ - ssh (client)
+ - Access to the SSH keys you saved with your fortrabbit Account - for example like [so](https://medium.com/trabe/use-your-local-ssh-keys-inside-a-docker-container-ea1d117515dc)
+
+
+
