Creating Infrastructure Templates

See also:
[exec] [INSERT] [SHOW] [ Using Variables ]

Cloud resources are deployed with StackQL using INSERT statements. INSERT templates for different cloud resources using the SHOW INSERT command.

Generating an INSERT template using the SHOW INSERT command​

An example of generating a template is shown here:

SHOW INSERT INTO google.compute.addresses;

This can be run through the shell or using an exec command as shown here:

./stackql exec 'show insert into google.compute.addresses' --output text --hideheaders

Returns : 

INSERT INTO google.compute.addresses(
  project,
  region,
  data__address,
  data__addressType,
  data__description,
  data__ipVersion,
  data__name,
  data__network,
  data__networkTier,
  data__prefixLength,
  data__purpose,
  data__subnetwork
)
SELECT
  '{{ .values.project }}',
  '{{ .values.region }}',
  '{{ .values.data__address }}',
  '{{ .values.data__addressType }}',
  '{{ .values.data__description }}',
  '{{ .values.data__ipVersion }}',
  '{{ .values.data__name }}',
  '{{ .values.data__network }}',
  '{{ .values.data__networkTier }}',
   {{ .values.data__prefixLength }},
  '{{ .values.data__purpose }}',
  '{{ .values.data__subnetwork }}'

This template can then be used along with a json or jsonnet data file to supply values at run time,for more information see Using Variables.

Generating an INSERT template with only required parameters​

To generate an StackQL INSERT template with only mandatory attributes use the /*+ REQUIRED */ query hint as shown here:

SHOW INSERT /*+ REQUIRED */ INTO google.compute.instances;

This can be run through the shell or using an exec command as shown here:

./stackql exec 'show insert /*+ REQUIRED */ into compute.instances' --output text -H

Returns : 

INSERT INTO google.compute.instances(
  project,
  zone,
  data__machineType,
  data__name
)
SELECT
  '{{ .values.project }}',
  '{{ .values.zone }}',
  '{{ .values.data__machineType }}',
  '{{ .values.data__name }}'
;
