Unable to start a new host / Misunderstanding what rancheros is maybe?

Archive RancherOS

I followed this video to set up a new host.

After installing the OS, I ran docker run -d --restart=always -p 8080:8080 --name rancher_admin rancher/server and get the web UI working.

When I try to add a custom host, the image is pulled and starts, but then stops and nothing happens apart for seeing my rancher.home host with the rancher/server container. I can successfully start an Nginx container within the same host with no issues.

I am learning RancherOS and Docker at the same time as I want to get familiar with containers so I can start learning DevOps skills for my job. I am trying to set up a server for home with an OwnCloud instance and then a simple storage dump for family/hobby photos and would like them both on their own host with a separate hostname which will be accessible outside of my home.

I am using a HP MicroServer Gen8 (which I believe is Baremetal?).

Any ideas? I have been spending a week on this on and off and starting to get frustrated. :frowning:

Can you do a docker ps and a docker ps -a?

Can you do a docker logs on whatever containers are for rancher/agent?

Have you looked here to see if any of this applies to you?

Hi @denise, thank you for a quick response.

Please see here for logs and docker ps ... output.

As there is nothing on there at the moment, I am more that happy for you to logon as it is a throw away install at the moment until I get to learn it more thoroughly; providing you require to of course :slight_smile:

I think I might be being stupid/misunderstanding something…?

What I want to do is use my home server, with RancherOS, to allow me to run an instance of OwnCloud + a back up server for my family photos/videos with the added extra of being able to spin up dev boxes for my personal projects and work stuff.

I am thinking a host is something where I can have multiple, for example:

owncloud.mydomain.co.uk
storage.mydomain.co.uk
some.project.mydomain.co.uk
some-other.project.mydomain.co.uk

I can then have the owncloud & storage instances to persist data on my raid array and have the dev boxes to have there own persistence on the OS drive.

Is this possible?

Am I misunderstanding something?

Most likely your rancher agents are unable to communicate with rancher/server instance.

What is the custom command that you run to add your host?

It was the command that was suggested by the UI. However, I didn’t set up a cloud-config.yml when I installed it? Could that have anything to do with this?

7

It has nothing to do with your OS.

Does your host registration say localhost?

8

No, currently it is the public IP of my machine.

Please ignore/close this. I was being stupid and using RancherOS + rancher/server incorrectly. As I am a web developer trying to get into DevOps/sys admin skill sets, I was thinking about hosts as virtual hosts and not actual hosts where you set up the server/agent on the server you are wanting to provision/monitor.

Apologies for any time wasted.
