Vagrant files to stand up a Local Rancher install with 3 nodes
This runs RancherOS as the base OS for the nodes which doesn't have the guest tools for Virtualbox installed
Start the cluster and the Rancher UI will become accessible on http://172.22.101.100
To see the contents of the registry cache proxy, navigate to http://172.22.101.100:5000/v2/_catalog
The default file will bring up a cattle environment. You can change this by editing orchestrator in the config file.
To use this you must have vagrant installed, which can be obtained from www.vagrantup.com
clone the directory and then run vagrant up
This has been tested with vagrant 1.9.1 and VirtualBox 5.0.32. If you experience issues with the networking it is likely related to running an older version.
The config.yml contains any variables that you should need to change, below is a description of the variables and their values:
orchestrator - Possible values are cattle, kubernetes, mesos and swarm
This sets the orchestrator that will be used for the environment, as part of the process the Default environment is deleted and we create a new one with the name of the orchestrator.
network_mode - Possible values are isolated, airgap and normal
isolated set the Rancher Server and Rancher nodes to have no external internet access other than via a proxy server that runs on the master node. This is used to emulate environments where a proxy server is required to access the internet
airgap sets the Rancher Server and nodes to have no external access at all. All images required to stand up Rancher are downloaded to a private repo on master and pulled from there
sslenabled - Possible values are true and false
This uses a pre-generated certificate to terminate the connection to the Rancher server with SSL. This certificate is located in the /certs folder. If this is changed then the public key will need to be replaced in the configure_rancher_node.sh script otherwise the agent will error.
ssldns - Default value is server.rancher.vagrant
The setting for this needs to match the string that is stored in the SSL certificate that is used for termination.
version - Possible values latest, stable, v1.x.x where x.x is any release of Rancher Server
This is the version of Rancher Server that you want to be deployed into your environment
rancher_env_vars - Pass through additional environment variables to the Rancher server
agent_version - The version of the Rancher agent for the nodes to pull
ROS_version - The version of RancherOS for the nodes to run, possible values are 1.0.3 and 1.0.4
master - Settings for the master node that runs the proxy, registry mirror etc., this value should not be changed
cpus - Default 1 This is the number of vCPU's that the master node should have
memory - Default 1024 This is the amount of RAM to be allocated to the master node, if running on a machine with only 8GB this should be dropped to 512
server - Settings for the server node(s) that runs the Rancher Server, this value should not be changed
count - Default 1 This is the number of Rancher Servers to run, if you want to test HA then this should be set to 2 or above
cpus - Default 1 This is the number of vCPU's that each server node should have
memory - Default 2048 This is the amount of RAM to be allocated to each server node, if running on a machine with only 8GB this should be dropped to 1024
node - Settings for the rancher node(s) that run in the Rancher environment, this value should not be changed
count - Default 3 This is the number of nodes to run
cpus - Default 1 This is the number of vCPU's that each Rancher node should have
memory - Default 2048 This is the amount of RAM to be allocated to each Rancher node, if running on a machine with only 8GB this should be dropped to 1024
ip - This section defines the IP address ranges for the virtual machines
master - Default 172.22.101.100
server - Default 172.22.101.101
node - Default 172.22.101.111
linked_clones - Default value true Leave as this as it reduces disk footprint
net - Network Settings section, this should not be changed
private_nic_type - Default 82545EM this sometime needs to be changed to 82540EM This is the network card that is emulated in the virtual machine
network_type - Default private_network
If you want to expose the Virtual Machines directly to the network this can be set to public_network
keys - Subsection for defining keys to be used when enabling external_ssh. The public key will be placed onto all servers, the private key will be placed onto just the master node. You can then use the master node as a jump host to each of the remaining VM's, or access them directly with the ssh key
public_key - This should be set to the path of the public key that needs to be uploaded
private_key - This should be set to the path of the private key that needs to be uploaded
external_access - To expose the setup to an external network
enabled - Default value false, Change to true if you want to expose the master node to an external network`
ssh_port - Default value 2277, this is the port that the master node will be exposed on if you enabled external_ssh
http_port - set this value to the local port on the host to forward to port 80 on the master
https_port - set this value to the local port on the host to forward to port 443 on the master
VM's starting but not running any scripts - Try changing the private_nic_type
