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

#In early development, sometimes you've got a hand-built instance, but you also don't want to leave it up all the time
# We've got an m4xl instance running Spinnaker (http://spinnaker.io) but we only really need it during the day
# As a cost-saving measure, we shut it down overnight.  However, we want it to be consistently accessible
# So this script is in a Jenkins job that runs every morning, 
# starting up the instance then updating its DNS record to the new IP.

#If you have multiple DNS records for a single instance, 
# you can safely run a second copy of the script with the ZONEID and RECORDSET updated appropriately.

# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName
