Prerequisites

Before you begin the process of deploying Glasswall Halo, ensure that you have the following tools and resources installed and setup.

System requirements​

The following guide has been written assuming it is being run on a Linux shell. If running on a different shell, some of the commands may need to be modified to run.

If running on Windows, please ensure you are using Windows subsystem for Linux.

Required tools​

Required AWS resources​

1. EKS cluster​

  • Recommended total of at least 8 vCPU and 32 GB RAM.
  • Minimum node size is 4 vCPU and 16 GB RAM.
  • For production workloads a minimum of 2 nodes is recommended.
  • Make sure the EKS cluster has an IAM OIDC provider.
    • Please refer to AWS documentation to determine if the cluster has an IAM OIDC provider or if you need to create one.
  • In the steps below, the EKS cluster is referred to as: eksname

Note : Glasswall Halo does not support ARM64 node VMs.

For guidance on creating an EKS cluster please refer to:

2. EFS​

An AWS Elastic File System (EFS) is used to create persistent volumes in EKS.

  • Create the EFS in the same VPC where the EKS is created.

For guidance on creating EFS please refer to:

3. IAM roles for service accounts​

Two IAM roles need to be created for 2 Kubernetes service accounts deployed through the Helm charts. The Amazon Resource Names (ARN) of these roles are required during deployment of the Helm charts.

  • Role 1: role-cdrp-efs-csi-<suffix\>
  • Role 2: role-cdrp-ext-secrets-<suffix\>
  • This shell script can be used to create the IAM roles.
  • Pass AWS region, EKS cluster name, filesystem ID and suffix as 4 arguments to the script. for e.g.
bash create-aws-roles.sh eu-west-1 eks-cdrp-dev fs-582a03f3 dev

For guidance on creating IAM roles for service accounts, please refer to AWS documentation.

4. MongoDB database​

MongoDB stores Glasswall Halo content management policies and is used by the cdrplatform-policy-api service.

  • Deploy a DocumentDB instance that is compatible with the MongoDB API.
  • You can skip this step if you do not require the Policy Management API or the Asynchronous API.
  • If DocumentDB is not available in AWS GovCloud, use the MongoDB Kubernetes Operator to deploy MongoDB in the EKS cluster.

Note: alternatively, MongoDB can be deployed directly within your cluster using the MongoDB Helm charts, as described in Step 7.

Access to Glasswall Artifact Registry​

  • You are provided with a token & token ID to access Glasswall's Artifact Registry (glasswallhub.azurecr.io).
  • This allows you to directly pull container images and Helm charts from your AKS cluster.
  • In the steps below, the token and token ID will be referred to as: token and token_id.
