IBM Cloud Private - My personal success ...

I've spent much of the past few days attempting to get IBM Cloud Private (ICP) 2.1.0 deployed onto my own set of Linux VMs.

This follows on from an internal enablement session last week, where I was able to get ICP up and running without huge problems.

So this time around, I created three VMs ( one for the boot/master/management node, one for a worker node and one for the proxy node ), which is probably a minimally viable configuration ( one would typically have 2-3 worker nodes, for scalability ).

I downloaded the latest Ubuntu Linux ( 17.10 aka Artful ), and then installed the latest version of Docker CE17.11.0-ce ).

Having followed the installation guide ( well, an edited version from the enablement ), I was disappointed to find that the installation failed with: -

At the suggestion of a friend, I checked my /etc/hosts file: -

and the ICP cluster hosts file: -

I'd previously ensured that I had sufficient disk ( 150 GB per VM ) and RAM ( 8 GB per VM ).

Overnight, I had an inspiration … and checked the System Requirements pages: -

Note that Ubuntu 17.10 is NOT listed.

For all supported operating systems, Docker Enterprise Edition and Docker Community Edition versions 1.12 to 1.13.1 are supported. Docker Community Edition versions 17.03, 17.05, and 17.06 and Docker Enterprise Edition version 17.03 are also supported.

Note that Docker 17.11 is NOT listed.

Once I switched to supported versions of Ubuntu: -

lsb_release -a

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 16.04.3 LTS
Release: 16.04
Codename: xenial

and a lower version of Docker: -

Yay, VMware Fusion and macOS Big Sur - no longer "NAT good friends" - forgive the double negative and the terrible pun ...

After macOS 11 Big Sur was released in 2020, VMware updated their Fusion product to v12 and, sadly, managed to break Network Address Trans...
