Addons

Prerequisites

  • terraform >= 1.0.0
  • AWS role configured and assumed(Route53 is used for TSB MP FQDN)
  • (optional) Azure role configured and assumed
  • (optional) GCP role configured and assumed gcloud auth application-default login

ArgoCD

Deploys Argo CD for gitops demo

# Deploys Argocd on all Clusters
make argocd

argocd is exposed using LoadBalancer type kubectl get svc -n argocd argo-cd-argocd-server, the username is admin and the password can be found in the outputs/terraform_outputs/terraform-argocd-<cloud>-<cluster_id>.json file (defaults to the tsb_password if set).

For details about the deployed applications, take a look at the manifests in the applications folder.

FluxCD

Deploys Flux CD for gitops demo

# Deploys Argocd on all Clusters
make fluxcd

For details about the deployed applications, take a look at the manifests in the applications folder.

TSB monitoring stack

Deploys the TSB monitoring stack to have metrics and dashboards showing the operational status of the different TSB components.

# Deploys the TSB monitoring stack in the management plane cluster
make tsb-monitoring

grafana is exposed using ClusterIP type. It can be accessed by port-forwarding port 3000 to the grafana pod in the tsb-monitoring namespace. The username is admin and the password can be found in the outputs/terraform_outputs/terraform-tsb-monitoring.json file (defaults to the tsb_password if set).

external-dns

Deploys external-dns per k8s cluster, where the DNS domain equals to $var.cluster_name.$var.external_dns_$cloud_dns_zone. For example, where the cluster name is gke-r161rc1p1-us-east1-0 and var.external_dns_gcp_dns_zone is set to gcp.sandbox.tetrate.io - the DNS domain will equal to gke-r161rc1p1-us-east1-0.gcp.sandbox.tetrate.io, and the sample DNS record will equal to test3.gke-r161rc1p1-us-east1-0.gcp.sandbox.tetrate.io.

General Defaults

variable "external_dns_annotation_filter" {
  default = ""
}

variable "external_dns_label_filter" {
  default = ""
}

variable "external_dns_sources" {
  default = "service"
}

variable "external_dns_interval" {
  default = "5s"
}

GCP Defaults

variable "external_dns_gcp_dns_zone" {
  default = "gcp.sandbox.tetrate.io"
}

Azure Defaults

variable "external_dns_azure_dns_zone" {
  default = "azure.sandbox.tetrate.io"
}

Deploy

Based on the cloud external_dns_$cloud_dns_zone variable have to be set or overwritten in terraform.tfvars file.

NOTE: AWS does not have a default external-dns zone set.

terraform.tfvars.json:

...
"external_dns_aws_dns_zone": "aws.sandbox.tetrate.io"
...
make external_dns

or per cloud, for example GCP:

make external_dns_gcp

Destroy

make destroy_external_dns

or per cloud, for example GCP:

make destroy_external_dns_gcp
