Aqua Security Gateway Helm Chart

Helm chart for installation and maintenance of Aqua Container Security Platform Gateway component to support multi-cluster use-case.

Contents

Prerequisites

Container Registry Credentials

Link

Installing the Chart

Follow the steps in this section for production grade deployments. You can either clone aqua-helm git repo or you can add our helm private repository (https://helm.aquasec.com)

Installing Aqua Gateway from GitHub Repo

  1. Clone the GitHub repository with the charts 
    git clone -b 2022.4 https://github.com/aquasecurity/aqua-helm.git
cd aqua-helm/
Edit values.yaml file in gateway directory with following details as prerequisite
  1. global.db.external.name - External database name
  2. global.db.external.host - External database public IP or endpoint URL
  3. global.db.external.port - External database port
  4. global.db.external.user - External database username
  5. global.db.external.password - External database password
  6. global.db.external.auditName - External audit database name
  7. global.db.external.auditHost - External audit database public IP or endpoint URL
  8. global.db.external.auditPort - External audit database port
  9. global.db.external.auditUser - External audit database username
  10. global.db.external.auditPassword - External audit database password
  11. console.publicIP - Aqua CSP console public IP or endpoint URL
  12. console.publicPort - Aqua CSP console public port
  // To load DB passswords from secrets:
  // change passwordFromSecret.enable to true
  // for loading DB password from secret edit passwordFromSecret.dbPasswordName  passwordFromSecret.dbPasswordName with secret name and secret key
  // for loading Audit-DB password from secret edit passwordFromSecret.dbAuditPasswordName  passwordFromSecret.dbAuditPasswordName with secret name and secret key
  // for loading PubSub DB password from secret edit passwordFromSecret.dbPubsubPasswordName  passwordFromSecret.dbPubsubPasswordName with secret name and secret key

  1. Create aqua namespace if gateway is being deployed to a new cluster.

    kubectl create namespace aqua

  2. Install Aqua

    helm upgrade --install --namespace aqua gateway ./gateway --set imageCredentials.username=<>,imageCredentials.password=<>,platform=<>

Installing Aqua Gateway from Helm Private Repository

  1. Add Aqua Helm Repository

    helm repo add aqua-helm https://helm.aquasec.com

  2. Check for available chart versions either from Changelog or by running the below command

    helm search repo aqua-helm/gateway --versions

  3. Create aqua namespace if gateway is being deployed to a new cluster.

    kubectl create namespace aqua

  4. copy the values.yaml content from Values.yaml to a file and make the respective changes values then run the following command:

    helm upgrade --install --namespace aqua gateway aqua-helm/gateway --values values.yaml --version <>

Configure mTLS between server/gateway and external DB

  1. Add the external DB values under global.db.external section
  2. Change global.db.ssl and global.db.auditssl to true
  3. Create secret with external DB public certificate 
    kubectl create secret generic <<dbcert_secret_name>> --from-file <<db_certificate.pem_file_path>> -n aqua
  4. Set the following variables 
    global.db.externalDBCerts.enable: true
global.db.externalDBCerts.certSecretName: <<dbcert_secret_name>>
  5. Select ssl mode for external databases 
    sslmode: require          # accepts: allow | prefer | require | verify-ca | verify-full (Default: Require)
auditsslmode: require     # accepts: allow | prefer | require | verify-ca | verify-full (Default: Require)
  6. Note: In Active-Active mode set respective values to pubsub variables
