How to configure

This is needed for first the usage only.

1. Configure AWS CLI if not done already
2. Install terraform (https://developer.hashicorp.com/terraform/downloads?product_intent=terraform)
3. Run terraform init in repository root directory
4. Install golang
5. Run git submodule update in repository root directory to fetch scylla terraform provider
6. Run go build in terraform-provider-scylladbcloud submodule directory to build it
7. Run ./create-tf-rc-file.sh in repository root directory, adjust local_scylla_provider_directory path inside the script first! (TODO: automate this)
8. Get API auth token for your account from Scylla Cloud support team.

How to provision

1. Run terraform apply -auto-approve in repository root directory
2. Do benchmarking
3. Run terraform destroy -auto-approve when you're done with the instances and table

Benchmarking

Benchmarking is not fully automated yet. You'd need to adjust some things but in general ./bench.sh can run on:

• DynamoDB
• Alternator
• Scylla CQL

Tips

• Run terraform output -json loader_public_ips anytime to get loader IPs
• Use ssh -v -o "StrictHostKeyChecking no" -i ./private_key ubuntu@{IP} to login into any instance
• In case something fails during apply you can safely retry it to continue and reconcile the state
• Create variables files named for instance defaults.tfvars with following content: dynamo_testing = false scylla_cloud_token = "YOUR_TOKEN_HERE" and use terraform commands with -var-file="defaults.tfvars" to avoid typing them every time.
