When using the UI to add hosts with the different cloud providers, the rancher/agent command is automatically launched for you with the host labels that are added in the UI. The value of this label will be used when programming rules for external DNS services. The host label can be added when registering the host or after the host has been added to Rancher, but it should be added to the host before the external DNS service starts. If you are planning to use an external DNS service and will require to program the DNS records using an IP other than the host IP, then you will need to include the label io._dns_ip= on the host. If you added two keys with different values, we’ll take the last inputted value to use as the key/value pair.īy adding labels to hosts, you can use these labels when schedule services/load balancers and create a whitelist or blacklist of hosts for your services to run on. The host label in the UI will be a key/value pair and the keys must be unique identifiers. The labels are added as an environment variable when launching the rancher/agent container. With each host, you have the ability to add labels to help you organize your hosts.
The agent version is tagged specifically to each Rancher server version. Rancher will automatically pull the correct image version tag for the rancher/agent and run the required version. When a host is added to Rancher, a rancher agent container is launched on the host. For cloud providers, we provision using docker-machine and support any images that docker-machine supports. We support adding hosts directly from cloud providers or adding a host that’s already been provisioned. After setting up your host registration, click on Save.

At any time, you can update the Host Registration. If you choose to change the address, please make sure to specify the port that should be used to connect to the Rancher API. By default, we have selected the management server IP and port 8080. This setup determines what DNS name or IP address, and port that your hosts will be connected to the Rancher API.

The first time that you add a host, you may be required to set up the Host Registration URL. The connections are point to point between hosts and AES encrypted, which is accelerated by most modern CPUs. It is generated on the server, stored in the database, and sent to the host as part of the agent registration with the API key pair. The registration token is per environment. There is not as much in the opposite direction for the agent to verify the host, so you can also set up TLS and the certificate will be verified. The agent accounts have access to only the resources they need in the API, replies to events are checked that the event was actually sent to that agent, etc. The design is that the agent is untrusted because it is running on the outside and potentially hostile (to the server) hardware. The key pair is then used for all subsequent communication using the same authentication and authorization logic as there is for other kinds of accounts, like environment API keys. Upon connection, it generates an agent account and API key pair in Rancher server.
The registration token, which is the long URL in the Add Host -> Custom screen, is used by the Rancher agent to connect to the server for the first time.
How do Hosts work?Ī host gets connected to Rancher server when the Rancher agent container is started on the host. Rancher also supports Docker Machine and allows you to add your host via any of its supported drivers.įrom the Infrastructure -> Hosts tab, click on Add Host. Ability to be routed to any other hosts under the same environment to leverage Rancher’s cross-host networking for Docker containers.Ability to communicate with a Rancher server via http or https through the pre-configured port.Includes when using release 7.3 or higher.

Please refer to the Docker documentation on how to change it. devicemapper using loopback, is not recommended by Docker. For RHEL/CentOS, the default storage driver, i.e.RancherOS, Ubuntu, RHEL/CentOS 7 are more heavily tested. Any modern Linux distribution that supports Docker 1.10.3+.Hosts are the most basic unit of resource within Rancher and is represented as any Linux server, virtual or physical, with the following minimum requirements: If you are looking for Rancher 2.x docs, see here. These docs are for Rancher v1.2, for the current 1.6 docs, see here.
