loadBalancer

loadBalancer resource is used to represent a loadbalancer as the name suggests.

You can create a loadBalancer resource by adding it to shippable.resources.yml

resources:
  - name:           <string>
    type:           loadBalancer
    integration:    <string>
    pointer:        <object>
  • name -- should be an easy to remember text string

  • type -- is set to loadBalancer

  • integration -- name of the subscription integration. The integration is only used when this resource is an input for a provision job. Currently supported integration types are:

  • pointer -- is an object that contains provider specific properties

    • For AWS Classic Load Balancers,

      pointer:
        sourceName:   <name of the Classic Load Balancer>
        method:       classic
        role:         <AWS IAM role used to update the Load Balancer>
      

      Note: role is and optional setting and if set, the role should have trust relationship allowing "ecs.amazonaws.com", if this is left blank, Shippable will search for one that has the right level of trust automatically. If none is found, the job where this resource is used will fail.

    • For AWS Application Load Balancers,

      pointer:
        sourceName:   <name of the target group ARN>
        method:       application
        role:         <AWS IAM role used to update the Load Balancer>
      

      Note: role is and optional setting and if set, the role should have trust relationship allowing "ecs.amazonaws.com", if this is left blank, Shippable will search for one that has the right level of trust automatically. If none is found, the job where this resource is used will fail.

    • For GKE Load Balancers used in provision jobs,

      pointer:
        sourceName:           <lowercase alphanumeric name only>
        method:               clusterIP | ExternalName | LoadBalancer | NodePort  #default is clusterIP
        namespace:            <name of the namespace where pod is deployed>       #optional
        clusterName:          <name of the GKE cluster>
        region:               <name of the region>
      version:
        ports:
          - name:             <string>
            protocol:         TCP | UDP #default TCP
            port:             <integer>
            targetPort:       <string>
            nodePort:         <integer>
        selector:
          <string> : <string>
        clusterIP:            None | "" | <string>
        externalIPs:
          - <string>
        sessionAffinity:      ClientIP | None
        loadBalancerIP:       <string>
        loadBalancerSourceRanges:
          - <string>
        externalName:         <string>
      

Used in Jobs

This resource is used as an IN for the following jobs:

Default Environment Variables

Whenever loadBalancer is used as an IN or OUT for a job that can execute user defined scripts, a set of environment variables are configured by the platform that may be useful to set the context before user defined scripts execute as part of the job. These variables are available when this resource is used.

<NAME> is the the friendly name of the resource.

Environment variable Description
<NAME>_NAME The name of the resource.
<NAME>_ID The ID of the resource.
<NAME>_TYPE The type of the resource. In this case loadBalancer.
<NAME>_INTEGRATION_<FIELDNAME> Values from the integration that was used. More info on the specific integration page.
<NAME>_OPERATION The operation of the resource; either IN or OUT.
<NAME>_PATH The directory containing files for the resource.
<NAME>_POINTER_METHOD Region defined in the pointer. Available if the integration is AWS or Google.
<NAME>_POINTER_ROLE ClusterName defined in the pointer. Available if the integration is AWS.
<NAME>_POINTER_NAMESPACE Namespace defined in the pointer. Available if the integration is Google.
<NAME>_SOURCENAME SourceName defined in the pointer.
<NAME>_VERSIONID The ID of the version of the resource being used.
<NAME>_VERSIONNAME The versionName of the version of the resource being used.
<NAME>_VERSIONNUMBER The number of the version of the resource being used.

Shippable Utility Functions

To make it easy to use these environment variables, the platform provides a command line utility that can be used to work with these values.

How to use these utility functions is documented here.
