Node Cluster Integration
The Node Cluster Integration is used to connect Shippable DevOps Assembly Lines platform to a cluster of VMs and deploy apps to the entire cluster.
Creating an Integration
You can add this integration by following steps on the Adding an integration page.
Here is the information you need to create this integration:
- Integration type -- Node Cluster
- Name -- choose a friendly name for the integration
- Nodes -- The IP addresses of the nodes in the cluster
Usage in Assembly Lines
The Node Cluster integration can be used in the following resources:
Default Environment Variables
When you create a resource with this integration, and use it as an
OUT for a
runCI job, a set of environment variables is automatically made available that you can use in your scripts.
<NAME> is the the friendly name of the resource with all letters capitalized and all characters that are not letters, numbers or underscores removed. Any numbers at the beginning of the name are also removed to create a valid variable. For example,
my-key-1 will be converted to
my_key_1 will be converted to
||Name supplied in the integration|
||List of Nodes 0 to N supplied in the integration|
||Private key used to access VMs|
||Public key used to access VMs|
Shippable Utility Functions
The platform also provides a command line utility called
shipctl that can be used to retrieve the values of these environment variables.
The specific function that can be used in the jobs yml is:
shipctl get_integration_resource_field <resource name> <field name>.
Here is a table that provides the mapping from the environment variable to the field name.
|Environment variable||Field Name|
