heat-templates

The heat-templates repository contains various examples of heat templates that will work with the CloudVPS OpenStack cloud.

All heat templates here are examples, and must be treated as such. There will be default values defined in order to make all templates work out-of-the box, that are not usable for production purposes without customisation.

All heat templats can be used via horizon however you will find the commandline client a lot friendlier. See our getting started guide on how to use the commandline client.

separate_examples

Separate examples can also be used via the horizon interface. Under "Orchestration" you will find "Stacks" where you can launch new stacks by referring to files or the gitlab raw url's.

Default_networking.yml: Create a basic internal network, router and a allow-all securitygroup.

Use as: openstack stack create -t Default_networking.yml <STACK_NAME>

webservers.yml: Add servers to existing internal network and install apache2 via userdata. Requires the presence of an internal network, by default named net-private like in "Default_networking.yml".

Use as: ```openstack stack create -t webservers.yml --parameter key_name=<KEY_NAME> <STACK_NAME>

LBaaS.yml: Create a LBaaS Loadbalancer for existing servers in a internal network.

WIP: Needs to have ports attached to the LB for the security group to work

WIP: %index% does not work, use LBaaS_2servers.yml instead.

LBaaS_2servers.yml: Create a LBaaS Loadbalancer for existing servers in a internal network.

WIP: Needs to have ports attached to the LB for the security group to work

VRRP_2servers.yml: Create 2 instances with a additional port for VRRP in a existing internal network and setup a basic haproxy configuration.

Use as: openstack stack create -t VRRP_2instances.yml --parameter key_name=<KEY_NAME> --parameter floating_ips=<FLOATING_IP> <STACK_NAME>

The more comprehensive examples require the use of multiple environment files and are only supported via the commandline.

LBaaS_with_env_file

Examples to create LBaaS with a environment file.

Use as;

openstack stack create -t LBaaS.yml -e LBaaS_env.yml <STACK_NAME>

LBaaS_resource.yaml is included by the environment file.

autscale_rtmp_example

Example on how to create an autoscaling rtmp cluster.

keepalived_vrrp_example

Example on how to create a VRRP setup with the required components. For more information on VRRP setup check out our blog post

new network
new router
reserved port on the new network
two ubuntu instances
install and configure keepalived
create a security group that allows vrrp and icmp
configure the correct metadata keys to allow VRRP

cluster_example_basic

Examples to create a keepalived cluster with LBaaS or two or more keepalived servers in front of 4 or more appservers.

Use as:

openstack stack create -t 01_create_cluster.yml -e 00_params.yaml -e 00_registry.yaml <STACK_NAME>

cluster_example

More detailed examples to create a keepalived cluster with LBaaS or two or more keepalived servers in front of 2 or more appservers.

Also includes internal dbservers with a keepalived ip and installs wordpress. This is for demo, getting started or P.O.C. purposes only. Failover does work however (sql) replication is not set up.
