Terraform Custom Provider for Citrix NetScaler

Description

This project is a terraform custom provider for Citrix NetScaler. It uses the [Nitro API] (https://docs.citrix.com/en-us/netscaler/11/nitro-api.html) to create/configure LB configurations.

Requirement

• hashicorp/terraform

Usage

Provider Configuration

netscaler

provider "netscaler" {
    username = "${var.ns_user}"
    password = "${var.ns_password}"
    endpoint = "http://10.71.136.250/"
}

Argument Reference

The following arguments are supported.

• username - This is the user name to access to NetScaler. Defaults to nsroot unless environment variable NS_LOGIN has been set
• password - This is the password to access to NetScaler. Defaults to nsroot unless environment variable NS_PASSWORD has been set
• endpoint - (Required) Nitro API endpoint in the form http://<NS_IP>/. Can be specified in environment variable NS_URL

The username, password and endpoint can be provided in environment variables NS_LOGIN, NS_PASSWORD and NS_URL.

Resource Configuration

netscaler_lbvserver

resource "netscaler_lbvserver" "foo" {
  name = "sample_lb"
  ipv46 = "10.71.136.150"
  port = 443
  servicetype = "SSL"
  lbmethod = "ROUNDROBIN"
  persistencetype = "COOKIEINSERT"
  sslcertkey = "${netscaler_sslcertkey.foo.certkey}"
}

Argument Reference

See https://docs.citrix.com/en-us/netscaler/11-1/nitro-api/nitro-rest/api-reference/configuration/load-balancing/lbvserver.html for possible values for these arguments and for an exhaustive list of arguments. Additionally, you can specify the SSL certkey to be bound to this lbvserver using the sslcertkey parameter

netscaler_service

resource "netscaler_service" "backend_1" {
  ip = "10.33.44.55"
  port = 80
  servicetype = "HTTP"
  lbvserver = "${netscaler_lbvserver.foo.name}"
  lbmonitor = "${netscaler_lbmonitor.foo.name}"
}

Argument Reference

See https://docs.citrix.com/en-us/netscaler/11-1/nitro-api/nitro-rest/api-reference/configuration/basic/service.html for possible values for these arguments and for an exhaustive list of arguments. Additionally, you can specify the LB vserver to be bound to this service using thelbvserverparameter, and thelbmonitor` parameter specifies the LB monitor to be bound.

netscaler_csvserver

resource "netscaler_csvserver" "foo" {
  name = "sample_cs"
  ipv46 = "10.71.139.151"
  servicetype = "SSL"
  port = 443
}

Argument Reference

See https://docs.citrix.com/en-us/netscaler/11-1/nitro-api/nitro-rest/api-reference/configuration/content-switching/csvserver.html for possible values for these arguments and for an exhaustive list of arguments. Additionally, you can specify the SSL cert to be bound using the sslcertkey parameter

netscaler_sslcertkey

resource "netscaler_sslcertkey" "foo" {
  certkey = "sample_ssl_cert"
  cert = "/var/certs/server.crt"
  key = "/var/certs/server.key"
  expirymonitor = "ENABLED"
  notificationperiod = 90
}

Argument Reference

See https://docs.citrix.com/en-us/netscaler/11-1/nitro-api/nitro-rest/api-reference/configuration/ssl/sslcertkey.html for possible values for these arguments and for an exhaustive list of arguments.

netscaler_cspolicy

resource "netscaler_cspolicy" "foo" {
  policyname = "sample_cspolicy"
  url = "/cart/*"
  csvserver = "${netscaler_csvserver.foo.name}"
  targetlbvserver = "${netscaler_lbvserver.foo.name}"
}

Argument Reference

See https://docs.citrix.com/en-us/netscaler/11-1/nitro-api/nitro-rest/api-reference/configuration/content-switching/cspolicy.html for possible values for these arguments and for an exhaustive list of arguments.

netscaler_lbmonitor

resource "netscaler_lbmonitor" "foo" {
  monitorname = "sample_lb_monitor"
  type = "HTTP"
  interval = 350
  resptimeout = 250
}

Argument Reference

Building

Assumption

• You have (some) experience with Terraform, the different provisioners and providers that come out of the box, its configuration files, tfstate files, etc.
• You are comfortable with the Go language and its code organization.

1. Install terraform from https://www.terraform.io/downloads.html
2. go get -u github.com/hashicorp/terraform
3. Install godep (https://github.com/tools/godep)
4. Check out this code: git clone https://<>
5. Build this code using make build

Running

1. Copy the binary (either from the build or from the releases page) terraform-provider-netscaler to an appropriate location. Configure .terraformrc to use the netscaler provider. An example .terraformrc:

providers {
    netscaler = "<path-to-custom-providers>/terraform-provider-netscaler"
}

2. Run terraform as usual

Samples

See the examples directory for various LB topologies that can be driven from this terraform provider.
