This OS knows about Docker, and so we use "docker run rancher/server" to create and run the rancher (server?) container, which has a UI that we can access via port 8080.This host installs RancherOS (makes sense.after all, every host needs an OS). Sudo docker run rancher/agent:v1.2.9), it turns out that on it are a number of containers running, one of which is named "dazzling_visvesvaraya", which seems to be the Rancher Server?!? After creating the host (which itself is created with the following docker command Is the host not the DockerVM that got created in my FreeNAS ui? That host which is running RancherOS, and is already hosting the RancherServer container just created by the earlier "docker run rancher/server" command?Įvidently not. It seems to me that what I am seeing here is the difference between RancherOS, and Rancher Server? Is RancherOS what got installed when I first ran the DockerVM, what the guide refers to as "it downloads the Rancher disk image file"? That is RancherOS(?).Īnyway, so after "rancher/server" is complete, you give it a minute or so to start up, and then you can access it's web UI by navigating your browser to :8080. Once logged in to rancher, you must "Download and install the rancher server with this command: docker run rancher/server"īut what is the difference between the "Rancher disk image file" that got downloaded when I first started the VM, and this 'rancher/server' image that is now being downloaded? The fact that I just did a Rancher login in order to even run this command tells me Rancher is already installed? Then once it is started, you use the terminal to execute the "cu" command to get to the rancher login. What is the role of Rancher or RancherOS in this? what is the role of Docker in this? What is the role of the host in rancher?įor example, the FreeNAS guide says that when the DockerVM is started the first time, "it downloads the Rancher disk image file". I have followed the FreeNAS 11.1 Guide and created a DockerVM, and then eventually got a Crashplan container running successfully to backup data in my FreeNAS zvol.īut I must be honest, and confess that I don't quite understand how all this hangs together. (Disclaimer: this is just me penning my thoughts and questions about the installation process, but also as a reference for me to come back to in a year or two or three from now when my server has died (or I have outgrown it and it needs replacement) and I need to go through this again)
