Docker-CE on Oracle Enterprise Linux 7

Here is how I install the latest Docker version on Oracle Linux 7. You find several blog posts about it which all install ‘docker-engine’. But things move fast in this agile world and docker package name has changed. The Community Edition is now ‘docker-ce’ and you want this one to run the latest version.

I’m on OEL 7.4 but should also wotj on RHEL 7:
[root@VM188 yum]# cat /etc/oracle-release

How to rename NIC in OEL 6.X

This is a quick note about host cloning and network interface (ethX) renaming.
As I wrote in my last post I have ESX lab now and I create a template of OEL 6.3 with all my settings and I would like use it for adding new VM (including RAC nodes). It is easy but there is one small issue – every time you clone VM network devices are renamed. Well MAC address is unique so it doesn’t surprise me but I would like to keep interface names like eth0, eth1 and eth2 and I got eth0, eth3, eth4 instead. Since OEL 5 (Redhat 5) all device name are generated by udev mechanism so I start my research there.
Well it was easier than I thought – there is a file in "/udev/rules.d" directory called "70-persistent-net.rules".
