Overview

Helps manage policies assigned to backend server instnace ports.

Creating a Backend Server Policy

Creating a backend server policy can be a bit tricky. A BackendServerAuthenticationPolicyType policy only has one attribute, a list of public key policies.

Before you can assign a policy to a backend server instance port you must create on of the appropriate type:

# step 1, create one (or more) PublicKeyPolicyType policies

public_key1 = "-----BEGIN CERTIFICATE-----\nMIICaTCCAdICCQDuvCF4erLGSjANBgkqhkiG9w0BAQUFADB5MQswCQYDVQQGEwJa\nWjENMAsGA1UECBMERkFLRTENMAsGA1UEBxMERkFLRTENMAsGA1UEChMERkFLRTEN\nMAsGA1UECxMERkFLRTENMAsGA1UEAxMERkFLRTEfMB0GCSqGSIb3DQEJARYQZmFr\nZUBleGFtcGxlLmNvbTAeFw0xMTA4MTAyMjE0NDVaFw0xMjA4MDkyMjE0NDVaMHkx\nCzAJBgNVBAYTAlpaMQ0wCwYDVQQIEwRGQUtFMQ0wCwYDVQQHEwRGQUtFMQ0wCwYD\nVQQKEwRGQUtFMQ0wCwYDVQQLEwRGQUtFMQ0wCwYDVQQDEwRGQUtFMR8wHQYJKoZI\nhvcNAQkBFhBmYWtlQGV4YW1wbGUuY29tMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCB\niQKBgQC4vy7K2LCgYJs7AbxdanPEwL4KLC9gi1LqzkRWShEaz8COUZswcOkevLQy\nSMFTXAvmH1FVqNO97wVG6ydxi+LNE7Jub62QQnsK420y+nXRTytxrboH1eAiAIEt\nZoUKaOymfAN8l/MJbcPH0rTYNdni99B+UMPWmFeRg/BeWiy2hwIDAQABMA0GCSqG\nSIb3DQEBBQUAA4GBAD+VNA6ia8TXa2lJgvmoGYCLGcCaccz7Nv/u4/oqv8qMPvdZ\n5DZxDLIExOSHiFGwWg5m8NgcirH2diveyRBgNhgC6S6DntkEMvAV0yvaQgHtUO53\no50MymfqtoVcebZcXbiDVAXW1cPEHKLBXecX6/LZ+GOzEsUOxgt7Xs9uabqp\n-----END CERTIFICATE-----\n"

public_key_policy = load_balancer.policies.create("pkp",
  'PublicKeyPolicyType', 'PublicKey' => public_key.strip)  

# step 2, create the backend server policy, passing the public key policy

name = 'backend-policy'
type = 'BackendServerAuthenticationPolicyType'
attributes = {
  # note: you can pass more than one public key policy here
  'PublicKeyPolicyName' => [public_key_policy]
}

backend_policy = @load_balancer.policies.create(name, type, attributes)
  'BackendServerAuthenticationPolicyType', attributes)

Once you have created a backend server authentication policy, you can assign it to a backend instance port:

load_balancer.backend_server_policies[80] = backend_policy

If you want to remove the policy you can pass nil instead.

# removes the policy from instance port 80
load_balancer.backend_server_policies[80] = nil

You can also get the current policy:

load_balancer.backend_server_policies[80] # returns a policy or nil
