You can configure Eureka as a health provider for your account with the following basic configuration in clouddriver:

eureka:
  provider:
    enabled: true
    accounts:
      - name: my-aws-account
        regions:
          - us-west-2
        readOnlyUrl: "http://10.0.0.1:8080/eureka/v2"

The provider also supports a region placeholder:

eureka:
  provider:
    enabled: true
    accounts:
      - name: my-aws-account
        regions:
          - us-west-2
          - us-east-1
        readOnlyUrl: "http://myhostname.{{region}}.mycompany.com:8080/eureka/v2"
      - name: my-second-aws-account
        regions:
          - us-west-1
        readOnlyUrl: "http://myhostname.{{region}}.mycompany.com:8080/eureka/v2"

Each account definition in AWS must also define a discovery field that denotes the URL for the writeable eureka.

- name: test
      environment: test
      accountType: main
      discovery: "http://mywriteableeureka.{{region}}.mycompany:8080/eureka/v2"
      accountId: 1234567899999
      regions:
        - name: us-east-1

By default, only one Eureka is supported per AWS account. If you have multiple aws.accounts configured in clouddriver which share an accountId, and wish to use a separate Eureka for each, then you can enable support by setting eureka.provider.allowMultipleEurekaPerAccount to true. For example:

    eureka:
      provider:
        allowMultipleEurekaPerAccount: true
        enabled: true
        accounts:
          - name: my-ci-account
            regions:
              - us-west-2
            readOnlyUrl: "http://10.0.0.1:8080/eureka/v2"
          - name: my-qa-account
            regions:
              - us-west-2
            readOnlyUrl: "http://10.0.0.2:8080/eureka/v2"

    aws:
      enabled: true
      accounts:
        - name: my-ci-account
          accountId: 1234567899999
          defaultKeyPair: 'my-keypair'
          environment: ci
          discovery: "http://10.0.0.1:8080/eureka/v2"
          regions:
            - name: us-west-2
        - name: my-qa-account
          accountId: 1234567899999
          defaultKeyPair: 'my-keypair'
          environment: qa
          discovery: "http://10.0.0.2:8080/eureka/v2"
          regions:
            - name: us-west-2

The eureka account name (eureka.provider.accounts[].name) must match the name of the AWS account (aws.enabled.accounts[].name) with which it shares the same Eureka. Please note that eureka.provider.allowMultipleEurekaPerAccount only works with AWS as the cloud provider. Additionally, this feature is not supported in the titus integration.
