Lets Encrypt has removed their ACME V1 api in favor of ACME V2. The Rancher 1.6 catalog entry for Lets Encrypt certificates doesn't support this api. There is a forked version of the repo, however the service has to be created manually instead of from the catalog.

1. Create a new service, give it a name, use vxcontrol/rancher-letsencrypt:v1.0.0 for the image
2. In the "Volumes" tab, add a volume /var/lib/rancher:/var/lib/rancher
3. In the "Command" tab, set the "Console" option to none
4. Click to add an Environment Variable, and paste the following into the first "Variable" input field.

• All of the environment variables should auto-fill.
• Fill in the necessary values

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/

# Instruct the interpreter to create a network request and create an object representing the request state. This can be done using the urllib module.

import urllib.request
import tarfile
thetarfile = "http://file.tar.gz"
ftpstream = urllib.request.urlopen(thetarfile)
thetarfile = tarfile.open(fileobj=ftpstream, mode="r|gz")
thetarfile.extractall()

# The ftpstream object is a file-like that represents the connection to the ftp server. Then the tarfile module can access this stream. Since we do not pass the filename, we have to specify the compression in the mode parameter.
