The purpose of this weblog publish is to offer greatest practices on how you can use terraform to configure Rockset to ingest the information into two collections, and how you can setup a view and question lambdas which might be utilized in an software, plus to point out the workflow of later updating the question lambdas. This mimics how we use terraform at Rockset to handle Rockset assets.
Terraform is probably the most in style used DevOps software for infrastructure administration, that allows you to outline your infrastructure as code, after which the software will take the configuration and compute the steps wanted to take it from the present state to the specified state.
Final we’ll have a look at how you can use GitHub actions to routinely run terraform plan for pull requests, and as soon as the pull request are authorised and merged, it would run terraform apply to make the required adjustments.
The total terraform configuration used on this weblog publish is accessible right here.
Terraform
To comply with alongside by yourself, you will have:
and also you additionally have to set up terraform in your laptop, which is so simple as this on macOS.
$ brew faucet hashicorp/faucet
$ brew set up hashicorp/faucet/terraform
(directions for different working methods can be found within the hyperlink above)
Supplier setup
Step one to utilizing terraform is to configure the suppliers we might be utilizing, Rockset and AWS. Create a file referred to as _provider.tf with the contents.
terraform {
required_providers {
aws = {
supply = "hashicorp/aws"
model = "~> 4"
}
rockset = {
supply = "rockset/rockset"
model = "0.6.2"
}
}
}
supplier rockset {}
supplier aws {
area = "us-west-2"
}
Each suppliers use atmosphere variables to learn the credentials they require to entry the respective companies.
- Rockset:
ROCKSET_APIKEYandROCKSET_APISERVER - AWS:
AWS_ACCESS_KEY_IDandAWS_SECRET_ACCESS_KEY, orAWS_PROFILE
Backend configuration
Terraform saves details about the managed infrastructure and configuration in a state file. To share this state between native runs in your laptop, and automatic runs from GitHub actions, we use a so referred to as backend configuration, which shops the state in an AWS S3 bucket, so all invocations of terraform can use it.
backend "s3" {
bucket = "rockset-community-terraform"
key = "weblog/state"
area = "us-west-2"
}
⚠️ For a manufacturing deployment, ensure to configure state locking too.
AWS IAM Function
To permit Rockset to ingest the contents of an S3 bucket, we first should create an AWS IAM function which Rockset will use to entry the contents of the bucket. It makes use of a information supply to learn details about your Rockset group, so it might configure AWS appropriately.
information rockset_account present {}
useful resource "aws_iam_policy" "rockset-s3-integration" {
title = var.rockset_role_name
coverage = templatefile("${path.module}/information/coverage.json", {
bucket = var.bucket
prefix = var.bucket_prefix
})
}
useful resource "aws_iam_role" "rockset" {
title = var.rockset_role_name
assume_role_policy = information.aws_iam_policy_document.rockset-trust-policy.json
}
information "aws_iam_policy_document" "rockset-trust-policy" {
assertion {
sid = ""
impact = "Permit"
actions = [
"sts:AssumeRole"
]
principals {
identifiers = [
"arn:aws:iam::${data.rockset_account.current.account_id}:root"
]
kind = "AWS"
}
situation {
take a look at = "StringEquals"
values = [
data.rockset_account.current.external_id
]
variable = "sts:ExternalId"
}
}
}
useful resource "aws_iam_role_policy_attachment" "rockset_s3_integration" {
function = aws_iam_role.rockset.title
policy_arn = aws_iam_policy.rockset-s3-integration.arn
}
This creates an AWS IAM cross-account function which Rockset is allowed to make use of to ingest information.
Rockset S3 integration
Now we are able to create the combination that allows Rockset to ingest information from S3, utilizing the IAM function above.
useful resource "time_sleep" "wait_30s" {
depends_on = [aws_iam_role.rockset]
create_duration = "15s"
}
useful resource "rockset_s3_integration" "integration" {
title = var.bucket
aws_role_arn = aws_iam_role.rockset.arn
depends_on = [time_sleep.wait_30s]
}
⚠️ You will get an AWS cross-account function error if you happen to skip the time_sleep useful resource, as a result of it takes a number of seconds for the newly created AWS function to propagate, so this protects you from having to rerun terraform apply once more.
Rockset assortment
With the combination we are actually in a position to create a workspace to carry all assets we’ll add, after which setup a assortment which ingest information utilizing the above S3 integration.
useful resource rockset_workspace weblog {
title = "weblog"
}
useful resource "rockset_s3_collection" "assortment" {
title = var.assortment
workspace = rockset_workspace.weblog.title
retention_secs = var.retention_secs
supply {
format = "json"
integration_name = rockset_s3_integration.integration.title
bucket = var.bucket
sample = "public/motion pictures/*.json"
}
}
Kafka Assortment
Subsequent we’ll setup a group from a Confluent Cloud supply, and add an ingest transformation that summarizes the information.
useful resource "rockset_kafka_integration" "confluent" {
title = var.bucket
aws_role_arn = aws_iam_role.rockset.arn
use_v3 = true
bootstrap_servers = var.KAFKA_REST_ENDPOINT
security_config = {
api_key = var.KAFKA_API_KEY
secret = var.KAFKA_API_SECRET
}
}
useful resource "rockset_kafka_collection" "orders" {
title = "orders"
workspace = rockset_workspace.weblog.title
retention_secs = var.retention_secs
supply {
integration_name = rockset_kafka_integration.confluent.title
}
field_mapping_query = file("information/transformation.sql")
}
The SQL for the ingest transformation is saved in a separate file, which terraform injects into the configuration.
SELECT
COUNT(i.orderid) AS orders,
SUM(i.orderunits) AS items,
i.deal with.zipcode,
i.deal with.state,
-- bucket information in 5 minute buckets
TIME_BUCKET(MINUTES(5), TIMESTAMP_MILLIS(i.ordertime)) AS _event_time
FROM
_input AS i
WHERE
-- drop all data with an incorrect state
i.deal with.state != 'State_'
GROUP BY
_event_time,
i.deal with.zipcode,
i.deal with.state
View
With the information ingested into a group we are able to create a view, which limits which paperwork in a group may be accessed by means of that view.
useful resource rockset_view english-movies {
title = "english-movies"
question = file("information/view.sql")
workspace = rockset_workspace.weblog.title
depends_on = [rockset_alias.movies]
}
The view wants an specific depends_on meta-argument as terraform doesn’t interpret the SQL for the view which resides in a separate file.
Alias
An alias is a technique to discuss with an present assortment by a special title. This can be a handy manner to have the ability to change the which assortment a set of queries use, with out having to replace the SQL for all of them.
useful resource rockset_alias motion pictures {
collections = ["${rockset_workspace.blog.name}.${rockset_s3_collection.movies.name}"]
title = "motion pictures"
workspace = rockset_workspace.weblog.title
}
As an example, if we began to ingest motion pictures from a Kafka stream, we are able to replace the alias to reference the brand new assortment and all queries begin utilizing it instantly.
Function
We create a task which is restricted to solely executing question lambdas solely within the weblog workspace, after which save the API key within the AWS Programs Supervisor Parameter Retailer for later retrieval by the code which can execute the lambda. This fashion the credentials won’t ever should be uncovered to a human.
useful resource rockset_role read-only {
title = "blog-read-only"
privilege {
motion = "EXECUTE_QUERY_LAMBDA_WS"
cluster = "*ALL*"
resource_name = rockset_workspace.weblog.title
}
}
useful resource "rockset_api_key" "ql-only" {
title = "blog-ql-only"
function = rockset_role.read-only.title
}
useful resource "aws_ssm_parameter" "api-key" {
title = "/rockset/weblog/apikey"
kind = "SecureString"
worth = rockset_api_key.ql-only.key
}
Question Lambda
The question lambda shops the SQL in a separate file, and has a tag that makes use of the terraform variable stable_version which when set, is used to pin the secure tag to that model of the question lambda, and if not set it would level to the most recent model.
Putting the SQL in a separate file isn’t a requirement, nevertheless it makes for simpler studying and you may copy/paste the SQL into the Rockset console to manually strive the adjustments. One other profit is that reviewing adjustments to the SQL is less complicated when it isn’t intermingled with different adjustments, like it might if it was positioned in-line with the terraform configuration.

query_lambda = rockset_query_lambda.top-rated.title
model = var.stable_version == "" ? rockset_query_lambda.top-rated.model : var.stable_version
workspace = rockset_workspace.weblog.title
}
Making use of the configuration
With all configuration information in place, it’s time to “apply” the adjustments, which signifies that terraform will learn the configuration information, and interrogate Rockset and AWS for the present configuration, after which calculate what steps it must take to get to the tip state.
Step one is to run terraform init, which can obtain all required terraform suppliers and configure the S3 backend.
$ terraform init
Initializing the backend...
Efficiently configured the backend "s3"! Terraform will routinely
use this backend until the backend configuration adjustments.
Initializing supplier plugins...
- Discovering hashicorp/aws variations matching "~> 4.0"...
- Discovering rockset/rockset variations matching "~> 0.6.2"...
- Putting in hashicorp/aws v4.39.0...
- Put in hashicorp/aws v4.39.0 (signed by HashiCorp)
- Putting in hashicorp/time v0.9.1...

- Put in rockset/rockset v0.6.2 (signed by a HashiCorp associate, key ID DB47D0C3DF97C936)
Associate and group suppliers are signed by their builders.
If you would like to know extra about supplier signing, you may examine it right here:
https://www.terraform.io/docs/cli/plugins/signing.html
Terraform has created a lock file .terraform.lock.hcl to document the supplier
alternatives it made above. Embrace this file in your model management repository
in order that Terraform can assure to make the identical alternatives by default when
you run "terraform init" sooner or later.
Terraform has been efficiently initialized!
Chances are you'll now start working with Terraform. Attempt operating "terraform plan" to see
any adjustments which might be required to your infrastructure. All Terraform instructions
ought to now work.
When you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working listing. When you neglect, different
instructions will detect it and remind you to take action if mandatory.
Subsequent we run terraform plan to get an inventory of which assets terraform goes to create, and to see the order during which it would create it.

So in about 1 minute it created all required assets (and 30 seconds had been spent ready for the AWS IAM function to propagate).
Updating assets
As soon as the preliminary configuration has been utilized, we would should make modifications to a number of assets, e.g. replace the SQL for a question lambda. Terraform will assist us plan these adjustments, and solely apply what has modified.
SELECT

We’ll additionally replace the variables.tf file to pin the secure tag to the present model, in order that the secure doesn’t change till we now have correctly examined it.
variable "stable_version" {

As you may see it up to date the question lambda model because the SQL modified.
Executing the Question Lambda
You may execute the question lambda from the command line utilizing curl. This reads the apikey from the AWS SSM Parameter Retailer, after which executes the lambda utilizing the newest tag.
$ curl --request POST
--url https://api.usw2a1.rockset.com/v1/orgs/self/ws/weblog/lambdas/top-rated-movies/tags/newest

GitHub Motion
To utilize Infrastructure as Code, we’re going to place all terraform configurations in a git repository hosted by GitHub, and make the most of the pull request workflow for terraform adjustments.
We are going to setup a GitHub motion to routinely run terraform plan for every pull request, and publish a touch upon the PR displaying the deliberate adjustments.
As soon as the pull request is authorised and merged, it would run terraform apply to make the adjustments in your pull request to Rockset.
