UPDATE (March 2020, thanks @ic): I don't know the exact AMI version but yum install docker now works on the latest Amazon Linux 2. The instructions below may still be relevant depending on the vintage AMI you are using.

Amazon changed the install in Linux 2. One no-longer using 'yum' See: https://aws.amazon.com/amazon-linux-2/release-notes/

Docker CE Install

sudo amazon-linux-extras install docker
sudo service docker start

Step 1 - Make a Discord Webhook

1. Find the Discord channel in which you would like to send commits and other updates

2. In the settings for that channel, find the Webhooks option and create a new webhook. Note: Do NOT give this URL out to the public. Anyone or service can post messages to this channel, without even needing to be in the server. Keep it safe!

Step 2 - Set up the webhook on Github

1. Navigate to your repository on Github, and open the Settings

rsync daemon mode over ssh

There are several common ways to do rsync backups of hosts over ssh:

1. As a non-root user. Upsides: very secure. Downside: cannot back up sensitive files.
2. As root, with a public key. Downsides: Whoever has the private key has full root access to the host being backed up.
3. As root, with a public key and a "forced command". Upsides: Restricts access to the server. Downsides: Requires either careful matching of rsync options (which might change over time), or "validator" scripts. Neither idea sounds very appealing to me.
4. Running rsync in daemon mode on the host being backed up. Upsides: Lots of useful options, like read-only mode, running as a different user if required, server-side excludes/includes, etc. Downsides: Opens up a TCP port that has full filesystem read access and is hard to secure (Ideally you could make the rsync daemon use a unix socket instead, that could be secured by filesystem permissions, but I haven't found a way to do that).

Here is another option t
