Maniftest File

Overview

The stackql_manifest.yml file is in the root of a project (or stack) directory. This yaml file defines all of the resources and their respective properties for all target deployment environments for your stack. Resources are processed in the order in which they are declared in this file, resources can include exports which are variables used for subsequent resources in your stack (for example a vpc_id needed to deploy a subnet). Global variables are configured here as well which can be sourced from external environment variables or secrets.

note

Secrets should not be saved in the stackql_manifest.yml file, use globals and externally sourced variables (using the -e or --env options) at deploy time.

Fields

the fields within the stackql_manifest.yml file are described in further detail here.

`name`

Type	`string`
Required	Yes

The name of the stack, by default this is derived by the init command from the stack directory name (replacing _ with - for resource and property name compliance). This name can be overridden, the value for name is exposed as a global variable called stack_name which is often used with resource or property values so ensure that this string conforms to any naming restrictions.

stackql_manifest.yml

name: kubernetes-the-hard-way

tip

Don't embed any environment symbols or designators in the name field, these are sourced at deploy time from the STACK_ENV argument to the build, test or teardown commands, and exposed for use in resource or property values as a global variable called stack_env.

`description`

Type	`string`
Required	No

Stack description, for documentation purposes only.

stackql_manifest.yml

description: stackql-deploy example for kubernetes-the-hard-way

`providers`

Type	`string[]`
Required	Yes

StackQL cloud or SaaS providers used in the stack. These are pulled from the stackql provider registry if they are not present at deploy time.

stackql_manifest.yml

providers:
  - google
  - aws

`globals`

Type	`global[]`
Required	Yes
Fields	`global.name`, `global.value`, `global.description`

Global variables used throughout the stack, can be an empty list if not required. Use the {{ YOUR_ENV_VAR }} notation in the value field of a globals list item to populate a global stack variable from an external environment variable or secret.

stackql_manifest.yml

globals:
- name: project
  description: google project name
  value: "{{ GOOGLE_PROJECT }}"
- name: region
  value: australia-southeast1
- name: default_zone
  value: australia-southeast1-a

`global.name`

Type	`string`
Required	Yes

Global variable name, this can be referred to in the resources section of the stackql_manifest.yml file or within queries using the {{ your_global_var_name }} syntax.

stackql_manifest.yml

globals:
- name: region
  value: ap-southeast-2

`global.value`

Type	`string`
Required	Yes

Global variable value, this can be a literal or sourced from an environment variable. The following example shows how to supply a string literal for the value:

stackql_manifest.yml

globals:
- name: region
  value: ap-southeast-2

The following example shows how to source value from an environment variable:

stackql_manifest.yml

globals:
- name: region
  value: {{ AWS_REGION }}

`global.description`

Type	`string`
Required	No

Global variable description, for documentation purposes only.

stackql_manifest.yml

globals:
- name: region
  description: default region  
  value: ap-southeast-2

`resources`

Type	`resource[]`
Required	Yes
Fields	`resource.name`, `resource.type`, `resource.file`, `resource.props`, `resource.exports`, `resource.protected`, `resource.description`

Defines resources in your stack, including the properties and their desired state values.

stackql_manifest.yml

resources:
- name: network
  description: vpc network for k8s-the-hard-way sample app
  props:
  - name: vpc_name
    description: name for the vpc
    value: "{{ stack_name }}-{{ stack_env }}-vpc"
  exports:
  - vpc_name    
  - vpc_link

note

A file with the name of the resource with an .iql extension is expected to exist in the resources subdirectory of your stack directory. You can reference a different file using the file field as shown here:

stackql_manifest.yml

- name: controller_instances
  file: instances.iql
  props:
  - name: num_instances
    value: 3
  - name: instance_name_prefix
    value: "{{ stack_name }}-{{ stack_env }}-controller"

`resource.name`

Type	`string`
Required	Yes

The name of the resource

stackql_manifest.yml

resources:
- name: network
...

`resource.type`

Type	`string`
Required	No

Resource type, values include : resource (default), query, script, multi

stackql_manifest.yml

resources:
- name: get_subnets
  type: query
...

info

resource will typically include create, update, delete, exists, statecheck and exports methods and is intended for provisioning or configuring a resource
query is designed to return data using an exports method
script is used to incorporate an external script in your stack definition (non StackQL query)
multi is used when resources are created in a loop (such as creating 3 vms)

`resource.file`

Type	`string`
Required	No

Query file for the resource (.iql file in the resources directory). Defaults to {resource.name}.iql

tip

Use file to reuse the same query template file for multiple different resources, as shown in the following example

stackql_manifest.yml

...
resources:
- name: internal_firewall
  file: firewalls.iql
  props:
  - name: fw_name
    value: "{{ stack_name }}-{{ stack_env }}-allow-internal-fw"
  - name: fw_direction
    value: INGRESS
  - name: fw_source_ranges
    values:
      dev:
        value: ["10.240.0.0/24", "10.200.0.0/16"]
  - name: fw_allowed
    value: [{IPProtocol: tcp}, {IPProtocol: udp}, {IPProtocol: icmp}]
- name: external_firewall
  file: firewalls.iql
  props:
  - name: fw_name
    value: "{{ stack_name }}-{{ stack_env }}-allow-external-fw"
  - name: fw_direction
    value: INGRESS
  - name: fw_source_ranges
    values:
      dev:
        value: ["0.0.0.0/0"]

  - vpc_link 

note

Variables listed as exports must be returned as columns in a exports query, for example:

/*+ exports */
SELECT 
'{{ vpc_name }}' as vpc_name,
selfLink as vpc_link
FROM google.compute.networks
WHERE name = '{{ vpc_name }}'
AND project = '{{ project }}'
