            Terraform Override Provider for use with Localstack
            Asked 2022-Mar-16 at 19:04

            I have a Git Repository with Terraform code that is being deployed into AWS. I am adding Localstack to this repository so that I can do higher-level validation testing before a plan and apply into my real AWS account. In order to use Localstack I have to create a new provider with the custom endpoint:



            Answered 2021-Oct-27 at 01:05

            Unfortunately because the configuration structure is quite significantly different between these two cases it's not really possible to make this dynamically switchable without the resulting configuration looking quite complicated, but it is possible to use Terraform language expression operators and dynamic blocks to set all of the provider arguments conditionally, and thus have a single provider configuration with dynamic settings rather than two separate provider configurations.

            The first thing to decide would be how you'll decide between the two possibilities. Since your localstack pseudo-infrastructure will unavoidably be distinct from the "real" infrastructure I expect you'll want to use a separate state for it, and so this could be a reasonable situation to use a separate workspace for development/testing, and I'll write this example assuming that the localstack configuration should be active whenever the workspace dev is selected. If that isn't what you want then hopefully this should still be enough to adapt to match your needs.

            How to setup S3 connection using .env variables in Airflow using Docker?
            Asked 2022-Feb-15 at 15:00

            Previously, a similar question was asked how-to-programmatically-set-up-airflow-1-10-logging-with-localstack-s3-endpoint but it wasn't solved.

            I have Airflow running in Docker container which is setup using docker-compose, I followed this guide. Now I want to download some data from an S3 bucket but I need to setup the credentials to allow that. Everywhere this only seems to be done using the UI by manually setting the AWS_ACCESS_KEY_ID & AWS_SECRET_ACCESS_KEY which exposes these in the UI, I want to set this up in the code itself by reading in the ENV variables. In boto3 this would be done using:



            Answered 2021-Aug-18 at 08:38

            The S3Hook takes aws_conn_id as parameter. You simply need to define the connection once for your airflow installation and then you will be able to use that connection in your hook.

            Default name of the connection is aws_default (see https://airflow.apache.org/docs/apache-airflow-providers-amazon/stable/connections/aws.html#default-connection-ids). Simply create the connection first (or edit if it is already there) - either via Airflow UI or via environment variable or via Secret Backends

            Here is the documentation describing all the options you can use:


            As described in https://airflow.apache.org/docs/apache-airflow-providers-amazon/stable/connections/aws.html - login in the connection is used as AWS_ACCESS_KEY_ID and password is used as AWS_SECRET_ACCESS_KEY, but AWS connection in the UI of Airflow is customized and it shows hints and options via custom fields, so you can easily start with the UI.

            Once you have the connection defined, S3 Hook will read the credentials stored in the connection it uses (so by default: aws_default). You can also define multiple AWS connections with different IDs and pass those connection ids as aws_conn_id parameter when you create hoook.

            DynamoDB table created by Terraform in LocalStack not visible in NoSQL Workbench
            Asked 2022-Jan-26 at 18:42

            Summary: Code and configuration known to show up in NoSQL Workbench when using DynamoDB Local mysteriously don't work with LocalStack: though the connection works, the tables no longer show in NoSQL Workbench (but continue to show up when using the aws-cli).

            I created a table in DynamoDB Local running in Docker that worked in NoSQL Workbench. I wrote code to seed that database, and it all worked and showed up in NoSQL Workbench.

            I switched to LocalStack (so I can interact with other AWS services locally). I was able to create a table with Terraform and can seed it with my code (using the configuration given here). Using the aws-cli, I can see the table, etc.

            But inside NoSQL Workbench, I couldn't see the table I created and seeded when connecting as shown below. There weren't connection errors; the table just isn't there. It doesn't seem related to the bugginess issue described here, as restarting the application did not help. I didn't change any AWS account settings like region, keys, etc.



            Answered 2021-Oct-01 at 13:46

            Summary: To use NoSQL Workbench with LocalStack, set the region to localhost in your code and Terraform config, and fix the resulting validation error (saying there isn't a localhost region) by setting skip_region_validation to true in the aws provider block in the Terraform config.

            The problem is disclosed in the screenshot above:

            NoSQL Workbench uses the localhost region.

            When using DynamoDB Local, it appears the region is ignored, so this quirk is hidden (i.e. there is a mismatch between the region in the Terraform file and my code on the one hand and NoSQL Workbench on the other, but it doesn't matter with DyanmoDB Local).

            But with LocalStack region is not ignored, so the problem popped up.

            I wouldn't have written this up except for one more quirk that took a while to figure out. When I updated the Terraform configuration thus:

            Answered 2021-Nov-04 at 20:12

            By default, when you list objects in a bucket, S3 collapses any objects with the same prefix before the separator as one entry, and marks this collection as PRE in the output. This lets you treat the contents of S3 buckets as a traditional filesystem with directories and files in those directories.

            You can either use aws s3 ls --recursive to list all objects in a bucket, or query the object directly by doing something like aws s3 ls s3://bucket-name/path/to/object to view that single object, if it exists.
