Localstack installation

This repo will install and configure localstack and crossplane inside a kind cluster running locally on your machine.

If you have a professional license for localstack, it will install the pro version otherwise the opensource version will be installed.

Prerequisites

In order to use this repo, there are certain prerequisites that have to be met.

Tools

You need the following tools installed to work with this repo.

• yq
• curl
• docker
• kind

The script also relies on both helm and kustomize however if these are not discovered in your environment, the script will download them temporarily to a bin folder at the current location ./

/etc/hosts file entry

To ensure communication, you need to add a hostfile entry for your primary interface pointing to localhost.localstack.cloud

192.168.1.2 localhost.localstack.cloud

LOCALSTACK_AUTH_TOKEN

If you have a professional license, set your auth token into your environment

export LOCALSTACK_AUTH_TOKEN=<your-token>

GITHUB_TOKEN

This script relies on the github api for discovering crossplane provider and function versions. To prevent being rate limited by github, you may want to set your github PAT into your environment

export GITHUB_TOKEN=<your-token>

Execution

To run using the defaults:

./localstack-kind.sh

By default, the build script will install common AWS providers and composition functions for crossplane to enable you to get started quickly.

Providers

• dynamodb
• ec2
• iam
• kms
• lambda
• s3
• sqs
• sns

Functions

• function-patch-and-transform
• function-go-templating

If you are running the professional version, the following providers will also be installed:

• rds
• eks

Providers can be added to this set by passing them as args to the script.

Likewise, providers can be removed by adding the name prefixed with a -

./localstack-kind.sh kinesis cloudformation -ec2 -lambda

This installation will build a new kind cluster called localstack using the configuration file kind.yaml.

The kind installation mounts the docker socket file /var/run/docker.sock and exposes ports 80, 443 and 4566 which nginx will bind to.

Once the cluster has started, nginx is installed with the following flags enabled

• --enable-ssl-passthrough - This hands off SSL to localstack so you're not having to worry about certiticates
• --tcp-services-configmap=ingress-nginx/tcp-services instructs NGINX to look for additional TCP services inside the tcp-services configmap

Localstack is installed using the values found inside localstack-values.yaml

It will also create a ProviderConfig with a dummy credential used to connect to localstack. Localstack itself doesn't care about the values but simply requires that "something" exists for them.
