Configure an Agent

Click on the desired cloud provider and follow the installation and configuration instructions:

AWS

Overview

Follow the steps below to install and configure an agent within your Amazon Web Services (AWS) environment.

Prerequisites

Step One - Create an Agent

Follow the Create an Agent guide to define an agent and generate the bootstrap config file that will be used in step two.

Step Two - Launch an agent in AWS

  1. Log in to the AWS Console.
  2. Click this link to be directed to the Control Plane Secure Communications Agent within the AWS Marketplace.
  3. Click the Continue to Subscribe button in the upper right corner.
  4. After reading the terms and conditions, click the Accept Terms.
  5. After the subscription has loaded, click the Continue to Configuration button in the upper right corner.
  6. Click the region pull-down and select the region where your AWS resources reside.
  7. Click the Continue to Launch button in the upper right corner.
  8. Click the Choose Action pull-down and select Launch through EC2. Click the Launch button.
  9. The Launch an instance wizard will be displayed.
  10. Under the Name and tag section, enter the agent's name. (e.g., cpln-agent).
  11. Under the Instance type section, select an applicable instance type.
TIP

Refer to the Agent Sizing Guidance page for additional details on which instance type to select.

  1. Optional: Under the Key pair(login) section, select or create a new key pair to enable SSH access to the agent. A key pair is necessary only for accessing the agent during troubleshooting.
TIP

If you do not have an AWS key-pair created, the console will help you to create one.

Since the agent instance will never need to be connected to (except for troubleshooting), you may proceed without a key-pair.

  1. Under the Network setting section, review the details and verify that the selected VPC is the same as the AWS resource you are trying to access.
TIP

For the agent to properly connect to the Control Plane servers, it requires outbound Internet access.

Verify that the Auto-assign Public IP option is set to Enable.

If your requirements do not allow the instance to have a public IP, please review the section How do instances without public IP addresses access the Internet in this AWS FAQ.

Either create or select an existing security group. The security groups belonging to the resources that the agent will need to have access to will require to have the security group belonging to the agent added to its list of allowed inbound traffic.

Initially, remove the checkbox for the "Allow SSH from" property. SSH access is only necessary for troubleshooting purposes. Control Plane will never need to connect directly to the agent.

  1. Under the Configure storage section, click the Advanced link and expand the volume property. Modify the Delete on termination dropdown to Yes. This will ensure the associated volume is removed if the agent is terminated, thereby preventing any orphaned volumes.

  2. Expand the Advanced details section. Scroll to the bottom and paste the contents of the JSON payload generated in step one within the User data textbox. Please review the other properties in this section to check if any default values need to be modified.

  3. Click Launch instance in the lower right corner.

  4. After a brief moment, the instance will launch and be ready to process requests.

Next Steps

Now that you have an agent configured and running, it can be used within an identity to allow your workload to connect to your internal AWS resources.

Next Steps

Now that you have an agent configured and running, it can be used within an identity to allow your workload to connect to your internal Azure resources.

GCP

Overview

Follow the steps below to install and configure an agent within your Google Cloud Platform (GCP) environment.

Prerequisites

Step One - Create an Agent

Follow the Create an Agent guide to define an agent and generate the bootstrap config file that will be used in step two.

Step Two - Launch agent in GCP

  • Using the Google Cloud SDK
  1. Install the latest SDK.
  2. If necessary, log in using gcloud init.
  3. Execute the command in the note below. Ensure that the instance will be deployed in the same VPC and region as your GCP resources. Use a unique INSTANCE_NAME and the bootstrap file (AGENT_NAME-bootstrapConfig.json) that was created in step one.
NOTE

gcloud compute instances create INSTANCE_NAME --image controlplane-agent-1398-958088785-43dce8055 --image-project cpln-build --metadata-from-file=user-data=AGENT_NAME-bootstrapConfig.json

TIP

Refer to the Agent Sizing Guidance page for additional details on which machine type to select.

Add the flag --machine-type=MACHINE_TYPE to the command above to select a different type. Otherwise, the default type is n1-standard-1.

  1. After a few moments, the command will return and show the status of the deployed instance.
  2. The agent will now be running, connecting to the Control Plane servers, and ready to process requests.

Step Three - Configure Firewall

By default, the GCP firewall rules open the common SSH, RDP, and ICMP ports to the world and allows all internal ports within the VPC. The agent does not need any of these ports open.

At a minimum, the agent needs to be able to connect to your GCP resources and the Internet.

Next Steps

Now that you have an agent configured and running, it can be used within an identity to allow your workload to connect to your internal GCP resources.

Private Network

Overview

Follow the steps below to install and configure an agent within your private network.

Prerequisites

Step One - Create an Agent

Follow the Create an Agent guide to define an agent and generate the bootstrap config file that will be used in step two.

Step Two - Launch agent locally

  1. Open a new shell and execute the following command. Use the bootstrap file that was created in step one.
copy
cpln agent up --bootstrap-file=PATH/AGENT_NAME-bootstrapConfig.json
TIP

If you are using Windows, follow these instructions:

  • Configure Docker to not use the WSL 2 based engine.
  • Run the cpln command above using a Windows command prompt and not using WSL.
  1. The agent will now be running, connecting to the Control Plane servers, and ready to process requests.

Next Steps

Now that you have an agent configured and running, it can be used within an identity to allow your workload to connect to your local resources.

TIP

When running an agent locally, it is running within a local Docker container. When configuring an identity network resource, you must use the IP of the network adapter that Docker installed on the local machine.

Kubernetes (k8s) Cluster

Overview

Follow the steps below to install and configure an agent within your k8s cluster.

Prerequisites

  • Review the Agent reference page.
  • Install the CLI.

Step One - Create an Agent

Follow the Create an Agent guide to define an agent and generate the bootstrap config file that will be used in step two.

Step Two - Launch agent within a k8s cluster

  1. Open a new shell and execute the following command. Update tokens as necessary. Use the bootstrap file that was created in step one.
copy
cpln agent manifest --bootstrap-file bootstrap.json --namespace NAMESPACE --replicas 2 --cluster CLUSTER_ID > manifest.yaml
# inspect/modify the manifest file manually, if needed.
kubectl apply -f manifest.yaml

cpln will generate the manifest.yaml file that will deploy two replicas of the agent to the namespace of your choice (NAMESPACE in the example). The parameter --cluster CLUSTER_ID will be added to the agent's status which is used as a hint to know which cluster an agent has been deploy to.

It is recommended to use --replicas=2 for high availability (HA).

On startup, the agent will generate a public/private key-pair which is persisted as a k8s secret. In this scenario, the agents run under a k8s service account, which can create/modify secrets in its own namespace. If this is a concern, the agent can be configured to run in a dedicated namespace.

  1. The agent will now be running, connecting to the Control Plane servers, and ready to process requests.

Next Steps

Now that you have an agent configured and running, it can be used within an identity to allow your workload to connect to your local resources.
