S3 Express Hot Lookup Walkthrough

Tear down

Progress checklist

Overview

Section titled “Overview”

Tear down means remove everything this walkthrough created. Two confirms, in order:

Terminal window
export AWS_PROFILE=sandbox
export AWS_REGION=ap-southeast-2
export S3X_LAB_ALLOW_AWS=1
./scripts/demo.sh down    # type LAB_SUFFIX
./scripts/image.sh down   # type s3x-hotlookup-harness
StepWrapperDeletes
1demo.sh downEC2, Standard + directory buckets, VPC / endpoints / SG, lab IAM, .lab-state.json
2image.sh downECR repo + images, CodeBuild project, source bucket, CodeBuild role, .image-state.json

Skipping step 2 leaves billable ECR storage and the CodeBuild source bucket.

demo.sh down
  terminate EC2 → empty + delete both buckets
  → VPC endpoints → subnet / routes / IGW → VPC → lab IAM


image.sh down
  → CodeBuild project → source bucket → ECR images + repo → CodeBuild role

Steps

Section titled “Steps”

  1. Remove the lab (demo.sh down).

    Terminal window
    export AWS_PROFILE=sandbox
    export AWS_REGION=ap-southeast-2
    export S3X_LAB_ALLOW_AWS=1
    ./scripts/demo.sh down

    Looks like (verified; type your stored LAB_SUFFIX when prompted — IDs are yours):

    This will delete VPC vpc-…, buckets, instance, and IAM for LAB_SUFFIX=20260920120148
    Type the LAB_SUFFIX to confirm: 20260920120148

    + aws … ec2 delete-internet-gateway …
    + aws … ec2 delete-vpc --vpc-id vpc-…
    Teardown complete. Removed …/.lab-state.json

  2. Remove the image pipeline (image.sh down).

    Required for a clean account. Type s3x-hotlookup-harness to confirm.

    Terminal window
    export AWS_PROFILE=sandbox
    export AWS_REGION=ap-southeast-2
    export S3X_LAB_ALLOW_AWS=1
    ./scripts/image.sh down

    Looks like (verified):

    This deletes ECR repo s3x-hotlookup-harness, CodeBuild s3x-hotlookup-harness,
    bucket s3x-hotlookup-cb-123456789012, and role s3x-hotlookup-codebuild
    Type the ECR repository name to confirm: s3x-hotlookup-harness
    + aws … ecr batch-delete-image …
    + aws … ecr delete-repository --repository-name s3x-hotlookup-harness …
    Image pipeline teardown complete.

  3. Manual lab order (only if you cannot use the wrappers).

    Terminal window
    # stop harness container on the instance, then:
    aws ec2 terminate-instances --instance-ids "$INSTANCE_ID"
    aws ec2 wait instance-terminated --instance-ids "$INSTANCE_ID"
    

    aws s3 rm "s3://${STD_BUCKET}" --recursive
    aws s3api delete-bucket --bucket "$STD_BUCKET"
    aws s3 rm "s3://${DIR_BUCKET}" --recursive
    aws s3api delete-bucket --bucket "$DIR_BUCKET"
    

    # delete vpc endpoints, then subnet/route/igw/vpc
    # remove role from instance profile, delete profile, delete-role-policy, delete-role
    # then still run: ./scripts/image.sh down

Verify

Section titled “Verify”

Sweep with the cleanup checklist. Nothing with the s3x-hotlookup- prefix should remain.

Next

Section titled “Next”

After the lab, read Where Express fits — single-AZ latency is not multi-AZ durability; do not keep the only copy of important data on Express.
