[1.1.1] — 2026-03-29

Added

• Amazon EC2 (ministack/services/ec2.py) — full API-level emulation (no real VMs)
  • Instances: RunInstances, DescribeInstances, TerminateInstances, StopInstances, StartInstances, RebootInstances
  • Images: DescribeImages — returns 3 stub AMIs (Amazon Linux 2, Ubuntu 22.04, Windows Server 2022)
  • Security Groups: CreateSecurityGroup, DeleteSecurityGroup, DescribeSecurityGroups, AuthorizeSecurityGroupIngress, RevokeSecurityGroupIngress, AuthorizeSecurityGroupEgress, RevokeSecurityGroupEgress
  • Key Pairs: CreateKeyPair, DeleteKeyPair, DescribeKeyPairs, ImportKeyPair
  • VPC: CreateVpc, DeleteVpc, DescribeVpcs, ModifyVpcAttribute — default VPC pre-created
  • Subnets: CreateSubnet, DeleteSubnet, DescribeSubnets, ModifySubnetAttribute — default subnet pre-created
  • Internet Gateways: CreateInternetGateway, DeleteInternetGateway, DescribeInternetGateways, AttachInternetGateway, DetachInternetGateway
  • Route Tables: CreateRouteTable, DeleteRouteTable, DescribeRouteTables, AssociateRouteTable, DisassociateRouteTable, CreateRoute, ReplaceRoute, DeleteRoute — default route table pre-created for default VPC
  • Network Interfaces (ENI): CreateNetworkInterface, DeleteNetworkInterface, DescribeNetworkInterfaces, AttachNetworkInterface, DetachNetworkInterface — full botocore-compliant response shape (availabilityZone, sourceDestCheck, interfaceType, privateIpAddressesSet)
  • VPC Endpoints: CreateVpcEndpoint, DeleteVpcEndpoints, DescribeVpcEndpoints — Gateway and Interface types; routeTableIdSet / subnetIdSet serialized correctly
  • Availability Zones: DescribeAvailabilityZones
  • Elastic IPs: AllocateAddress, ReleaseAddress, AssociateAddress, DisassociateAddress, DescribeAddresses
  • Tags: CreateTags, DeleteTags, DescribeTags
  • Default VPC, subnet, security group, internet gateway, and route table always present
  • Rules stored but not enforced (matches LocalStack behaviour)
  • 26 integration tests
• Step Functions Activities — full worker-based activity task pattern
  • CreateActivity, DeleteActivity, DescribeActivity, ListActivities — full CRUD
  • GetActivityTask — async long-poll (up to 60 s) returning taskToken + input to worker; non-blocking (uses asyncio.sleep — does not stall the event loop)
  • Activity Task state execution — when a Task state's Resource is an activity ARN, the execution enqueues the task and waits for a worker to call SendTaskSuccess or SendTaskFailure
  • ActivityAlreadyExists raised on duplicate CreateActivity (matches AWS behaviour — not idempotent)
  • ActivityDoesNotExist raised on DeleteActivity, DescribeActivity, GetActivityTask for unknown ARN
  • Activity ARN format: arn:aws:states:{region}:{account}:activity:{name}
  • 5 integration tests: CRUD, list, duplicate-name error, worker success flow, worker failure flow

Tests

• 644 integration tests — all passing
