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.
#DOCKER LOOPBACK ADDRESS INSTALL#
In the Advanced Options section, there is a Docker Install URL. Note: If you are launching a host from the UI, you can select which version of Docker you’d like to install on the host. Exact patch releases are also available as 1.sh, e.g. These are a slightly modified version of the standard script and pin the installation to a specific Docker engine version. Instead, we recommend you use the scripts above to install a specific version. The standard curl | sh always installs the latest Docker release available at that time and may not be supported by your installed Rancher version. Note: We will not support the test/nightly/edge releases of Docker, but will support the stable releases of Docker. 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. For RHEL/CentOS, if you want to enable SELinux, you will need to install an additional SELinux module.
#DOCKER LOOPBACK ADDRESS HOW TO#
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 with a supported version of Docker.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: These docs are for Rancher 1.6, if you are looking for Rancher 2.x docs, see here.
