Recently I got to know about RancherOS, which is an OS that provides pretty much only Docker host environment so that you can launch Docker containers.
My test environment is Mac OS Sierra with VMWare Fusion 8.5. What I did was as follows:
- Download ISO file for RancherOS
- Launch ISO via VMWare Fusion with 1GB ram and 10GB disk space (That’s normally what I use for linux distribution guest environment)
- Once I was on RancherOS terminal, I created cloud-config.yml file with ssh publick key in it. (Refer to the instruction)
- I made a note of IP address for the step #5
- After installing to the disk, I chose to reboot. From Mac terminal, I ssh’ed to the IP address of the RancherOS guest after RancherOS guest became available.
Pretty straightforward to install RancherOS on my mac.
RancherOS provides its own command line tool called ‘ros’ and this is the tool to configure the system, docker, etc.
