Community Cloud Pods
LocalStack supports Community Cloud Pods to give our community users a limited Cloud Pods experience. Using Community Cloud Pods, you get two commands:
load to save the container state in a Cloud Pod and dump it into their running LocalStack container at any given time, respectively.
In this getting started guide, we will demonstrate how community users can leverage Community Cloud Pods to save the state of their running LocalStack instance permanently. To get started, you would only need
awscli installed. We intend this feature to be open to community users; hence no
LOCALSTACK_API_KEY is required.
Let us start by creating some AWS resources in LocalStack. Just a mere example, let us create a S3 bucket and a SQS queue:
$ awslocal s3 mb s3://test $ awslocal sqs create-queue --queue-name test-queue
Let us dump such a simple state into a Cloud Pod using the
save command. This command takes a file URI as an argument and creates a ZIP file in the specified directory. Assuming we want to create a pod named
awesome-pod in our Desktop folder, we will run the below commands to save an
awesome-pod in your Desktop directory:
$ localstack pod save file:///Users/<my_username>/Desktop/awesome-pod Cloud Pods file:///Users/<my_username>/Desktop/awesome-pod successfully exported
This exported ZIP file now contains the state we previously created, and we can restore it at any time with the inverse command, i.e.,
load. For instance, the following command will restore the same state of a fresh instance of LocalStack:
$ localstack pod load file:///Users/<my_username>/Desktop/awesome-pod Cloud Pods file:///Users/<my_username>/Desktop/awesome-pod successfully loaded
It is worth noting that the
load command also allows loading a Cloud Pod stored at a given URL. We also provide a short-hand option to load Cloud Pods saved in a public GitHub repository. To showcase this possibility, we opened a new public repository at localstack/cloud-pods, where we started storing several Cloud Pods for demonstration purposes.
For example, we uploaded a Cloud Pod named
s3-trigger-thumbnail based on an official AWS documentation tutorial. This Cloud Pod stores a simple application consisting of two S3 buckets and a Lambda function. For each
jpg image uploaded in one of the buckets, the Lamda function will create a thumbnail of it and store it in the other bucket.
To load this Cloud Pod, you can run the following command:
$ localstack pod load git://localstack/cloud-pods/s3-trigger-thumbnail
The above command is equivalent to:
$ localstack pod load https://raw.githubusercontent.com/localstack/cloud-pods/main/s3-trigger-thumbnail
To test the loaded pod, you can run the following command:
$ awslocal s3 cp <path_to_file>.jpg s3://img-bucket
To check the content of the destination bucket run the following command:
$ awslocal s3 ls s3://img-bucket-resized
Community Cloud Pods have some limitations:
- Only Community-available AWS services can be saved and loaded in a Community Cloud Pod.
- Users are responsible for storing their saved states. Pro users can use our Cloud Pods platform to make storing and sharing their saved states easier.
- Cloud Pods for Community users do not support versioning out of the box.
