RancherOS hosting Kontena


#1

Greetings All,

Hope that your day is going well.

I have been researching and playing around with may container related systems lately and must say that I TRULY like that RancherOS is completely containerized even to the system level and also that its footprint is extremely small. This makes for an amazing system.

In the past I have installed RancherOS as well as the Rancher Server onto a few nodes for testing and it seems to work pretty well, but have wanted to find out about the possibility of doing something a bit different, mostly as a test but with a strong curiosity as well.

In my travels, I have come across Kontena (https://github.com/kontena/kontena and https://www.kontena.io/docs/) which is also a very interesting container orchestration framework much like Rancher Server, but mostly a CLI approach.

I would like to see about installing Kontena on RancherOS.

From what I can see in the docs (https://www.kontena.io/docs/slow-start.html) and for the Linux installation, it seems to need “Ruby version 2.1 or later installed on your system” and I am not sure how to go about installing this on RancherOS.

So then my questions would be:

  1. Has anyone tried to install Kontena on RancherOS.

  2. Does anyone have any ideas on how to install Ruby on RancherOS?

Any assistance would be greatly appreciated.

Thanks in advance and have a great day,
Lonnie

Kontena components can be run as Docker containers. I think the easiest way is to use Docker Compose:

  1. Installing Kontena Master: https://kontena.io/docs/advanced/install-master/docker-compose.html
  2. Installing Kontena Nodes: https://kontena.io/docs/using-kontena/install-nodes/docker-compose.html#create-kontena-node

Ruby is required for using Kontena CLI so you don’t need to install it into RancherOS.

Thanks for the update on Kontena.

I had actually ran across those links on their website and then
subsequently found:

https://hub.docker.com/u/kontena/

https://hub.docker.com/r/kontena/server/
https://hub.docker.com/r/kontena/agent/
https://hub.docker.com/r/kontena/lb/
https://hub.docker.com/r/kontena/cli/

but have not tried them yet…

I have also just found that SoftEther in a container works well with
RancherOS also.

Thanks again,
Lonnie :slight_smile:
