If you followed the last posts (Rancher, up and running, on EC2 \u2013 1 \u2013 One node<\/a>, Rancher, up and running, on EC2 \u2013 2 \u2013 Three nodes <\/a> and Rancher, up and running, on EC2 \u2013 3 \u2013 Rancher setup<\/a>) about Rancher, you know how to setup Rancher in a highly available RKE cluster. While this is the way to go for a production clusters, you might want to play with Rancher on a local VM and there is a solution for this as well. In the previous posts I’ve used Debian<\/a> as the operating system, but as Rancher Labs was recently acquired by SUSE<\/a> we’ll be using SLES 15<\/a> for the scope of this post: Bring up a Rancher playground on a single VM using SLES 15.<\/p>\n

<\/p>\n

As this is intended to be a step by step guide, we’ll start from the very beginning: Download the SLES 15 ISO from here<\/a> (you’ll need to create a free SUSE account for this). I’ve downloaded “SLE-15-SP2-Online-x86_64-GM-Media1.iso”, this is a minimal ISO which fetches all required packages from the SUSE repository. I prefer to do it like this, instead of downloading the full blown ISO. No matter which virtualization product you use, go through the standard setup and opt for a minimal installation:<\/p>\n

\"\"<\/a>

\n\"\"<\/a>
\n\"\"<\/a>
\n\"\"<\/a>
\n\"\"<\/a>
\n\"\"<\/a>
\n\"\"<\/a><\/p>\n

You should have received a registration code after you created your SUSE account and downloaded the ISO. This on needs to go here:

\n\"\"<\/a>

\n\"\"<\/a>
\n\"\"<\/a><\/p>\n

Once the installation completed login, set a host name and update the system (which actually already is up to do as we fetched all sources from the SUSE repository):<\/p>\n

\nlocalhost:~ $ hostnamectl set-hostname sles15ranger\nlocalhost:~ $ zypper update\nRefreshing service 'Basesystem_Module_15_SP2_x86_64'.\n...\nReading installed packages...\nNothing to do.\nlocalhost:~ $ \n<\/pre>\n
Very much the same as in the previous posts, install a supported version of Docker:<\/p>\n
\nsles15ranger:~ $ curl https:\/\/releases.rancher.com\/install-docker\/19.03.sh | sh\n  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current\n                                 Dload  Upload   Total   Spent    Left  Speed\n100 17251  100 17251    0     0  84151      0 --:--:-- --:--:-- --:--:-- 84151\n\nEither your platform is not easily detectable or is not supported by this\ninstaller script.\nPlease visit the following URL for more detailed installation instructions:\n\nhttps:\/\/docs.docker.com\/engine\/installation\/\n<\/pre>\n
Ok, the official script from Rancher to install Docker is not working on SLES 15. Let’s try to find Docker in the official SUSE repositories:<\/p>\n
