This operation installs a Gateway Node on endpoints configured with the resource 'Oracle API Platform Node Server' on the environment instance. The operation requires a gateway-props.json file for configuration. See the special considerations below for more information on the gateway-props.json file.

Environment/Instance Properties

Property Name	Property Code	Required	Description
Oracle API Platform Account	FDOAP_CLOUD_ACCOUNT_CODE	Y	The Oracle API Platform cloud account to use for this operation.
Oracle Gateway Install Home	FDOAP_GATEWAY_INSTALL_HOME	Y	Absolute location of where to install the gateway node configuration. This is where the executable and libraries will be located. This should be empty prior to running this operation. Note that this is different compared to the '*nodeInstallDir*' property in the gateway-props.json
Node Weblogic User	FDOAP_NODE_WL_ADMIN_USER	Y	Weblogic admin user to configure when creating the node. Oracle API Platform Nodes are weblogic servers and this is your admin user.
Node Weblogic Password	FDOAP_NODE_WL_ADMIN_PASSWORD	Y	Weblogic admin password to configure when creating the node.

Inputs

Input Name	Input Code	Required	Description
Gateway File	FDOAP_INP_GATEWAY_NODEPROPS_FILE	Y	Json node properties file to use for creation. Can be absolute path or relative to artifacts directory. See Special Considerations below for more information.
Copy Node Properties	FDOAP_INP_COPY_NODE_PROPS	N	If true, the 'Gateway File' input specified will be copied to the Node Install home. This will allow you to reuse this node properties file in other workflow steps, like 'executeNodeAction'.
Auto Approve Registration	FDOAP_INP_APPROVE_NODE_REG	N	By default, when a Node is installed a request is sent to the Logical Gateway for Approval to join the Logical Gateway. If this is true, the request will be auto approved. In order for this to work the Oracle API Platform user must have 'NodeServiceAccount' grant on the Gateway. This can be automatically added if using the 'ImportGateway' operation.
Install Action Override	FDOAP_INP_INSTALL_ACTION_OVERRIDE	N	By default, 'install-configure-start-join' is used when installing the Node. This means it expects the Logical Gateway to be existing ahead of time. You can override this to 'install-configure-start-create-join' which will create the Logical Gateway and Gateway Node in one shot. Depending on the action chosen, different or additional properties may be required in the Gateway File.

Outputs

Output Name	Description
FDOAP_OUT_GATEWAY_ID	Logical Gateway Id after installation. Useful if your install action is overridden to create and join
FDOAP_OUT_NODE_ID	Gateway Node Id that was installed.

Artifacts

This operation consumes artifacts from the artifacts repository.

Endpoint Selection

This operation will select all available endpoints associated to the environment instance which have resource type of Oracle API Platform Node Server.

Endpoint Execution

This operation will select all available endpoints associated to the environment instance which have resource type of Oracle API Platform Node Server.

Special Considerations

Gateway File (gateway-props.json)

The gateway-props.json file provided is the same file required by Oracle for Node installation: https://docs.oracle.com/en/cloud/paas/api-platform-cloud/apfad/install-gateway-node.html#GUID-A02059C9-37B4-40F0-9FEA-C648804BB98F

FlexDeploy however derives certain properties to help make the configuration easier. Below are the required properties for installation through FlexDeploy.

Required Properties

Property Key	Description	Required	Example Value	Recommendation
logicalGatewayId	Logical Gateway Id to join the Node to. Only required if using the default Node install action.	Sometimes	117	FlexDeploy property ${{FDOAP_GATEWAY_ID}}.
logicalGateway	Logical Gateway Name to create during installation. Only required when running 'install-configure-start-create-join'	Sometimes	Development	Either create your own FD property or some variation on FD_ENVIRONMENT_NAME
gatewayNodeName	The name of the Gateway Node to create.	Yes	Node MyDevServer	Node ${{FD_ENDPOINT_NAME}}
gatewayNodeDescription	The description you see when inspecting the node.	Yes	Created through FlexDeploy	Include ${{FD_PROJECT_VERSION}} somewhere
listenIpAddress	The internal IP used for configuration	Yes	yourinternalhost	Could potentially use ${{FD_ENDPOINT_ADDRESS}}
publishAddress	The public IP used for configuration	Yes	yourhost	Could potentially use ${{FD_ENDPOINT_ADDRESS}}
nodeInstallDir	Directory where to install the node. This is different than 'Oracle Gateway Install Home' above.	Yes	/opt/apiplatform/node	Keep this the same across Nodes for consistency.
gatewayExecutionMode	Development\|Production. Development has certain networking security disabled.	Yes	Development	Create a user defined input

Derived Properties

The following fields are dynamically added and removed from the file. If you do not wish to change the values then you can safely ignore this section. If you want to set custom values for any of the below fields you can simply set them in your gateway-props.json file and they will take precedence.

Property Key	Derived Value
gatewayadminName	Node Weblogic User Environment Instance Property
gatewayadminPassword	Node Weblogic Password Environment Instance Property
gatewayManagerUser	Oracle API Username Cloud Account Property
gatewayManagerPassword	Oracle API Password Cloud Account Property
clientId	Oracle API Client Id Cloud Account Property
clientSecret	Oracle API Client Secret Cloud Account Property
gatewayRuntimeUser	Oracle API Username Cloud Account Property
gatewayRuntimePassword	Oracle API Password Cloud Account Property
managementServiceUrl	Oracle API Platform Url Cloud Account Property
idcsUrl	Oracle Identity Url Cloud Account Property
requestScope	Combination of Audience and Scope Cloud Account Properties. Also adds 'offline_access'.

One file with FlexDeploy Properties or one file per environment

If you do not want to use FlexDeploy properties in your file then I would suggest creating one file per environment and using an expression to resolve the Gateway File input.

For example you could have the following files in source control:

gateway-props-dev.json
gateway-props-test.json
gateway-props-prod.json

Your input would then be the following expression: "gateway-props-"+FD_ENVIRONMENT_CODE.toLowerCase()+".json"

There are several additional optional fields that can be specified in the gateway-props.json. Any field in the Oracle documentation is allowed.

Sample gateway-props.json file

{
    "logicalGatewayId" : "${{FDOAP_GATEWAY_ID}}",
    "gatewayNodeName" : "Node ${{FD_ENDPOINT_NAME}}",
    "gatewayNodeDescription" : "Installed through FlexDeploy.  Version: ${{FD_PROJECT_VERSION}}",
    "listenIpAddress" : "${{FD_ENDPOINT_ADDRESS}}",
    "publishAddress" : "${{FD_ENDPOINT_ADDRESS}}",
    "nodeInstallDir" : "/opt/apiplatform/node",
    "gatewayExecutionMode" : "Development"
}
