BastionHostLinux

class aws_cdk.aws_ec2.BastionHostLinux(scope, id, *, vpc, availability_zone=None, block_devices=None, instance_name=None, instance_type=None, machine_image=None, security_group=None, subnet_selection=None)

Bases: aws_cdk.core.Construct

This creates a linux bastion host you can use to connect to other instances or services in your VPC.

The recommended way to connect to the bastion host is by using AWS Systems Manager Session Manager.

The operating system is Amazon Linux 2 with the latest SSM agent installed

You can also configure this bastion host to allow connections via SSH

__init__(scope, id, *, vpc, availability_zone=None, block_devices=None, instance_name=None, instance_type=None, machine_image=None, security_group=None, subnet_selection=None)
Parameters
  • scope (Construct) –

  • id (str) –

  • vpc (IVpc) – VPC to launch the instance in.

  • availability_zone (Optional[str]) – In which AZ to place the instance within the VPC. Default: - Random zone.

  • block_devices (Optional[List[BlockDevice]]) – Specifies how block devices are exposed to the instance. You can specify virtual devices and EBS volumes. Each instance that is launched has an associated root device volume, either an Amazon EBS volume or an instance store volume. You can use block device mappings to specify additional EBS volumes or instance store volumes to attach to an instance when it is launched. Default: - Uses the block device mapping of the AMI

  • instance_name (Optional[str]) – The name of the instance. Default: ‘BastionHost’

  • instance_type (Optional[InstanceType]) – Type of instance to launch. Default: ‘t3.nano’

  • machine_image (Optional[IMachineImage]) – The machine image to use. Default: - An Amazon Linux 2 image which is kept up-to-date automatically (the instance may be replaced on every deployment).

  • security_group (Optional[ISecurityGroup]) – Security Group to assign to this instance. Default: - create new security group with no inbound and all outbound traffic allowed

  • subnet_selection (Optional[SubnetSelection]) – Select the subnets to run the bastion host in. Set this to PUBLIC if you need to connect to this instance via the internet and cannot use SSM. You have to allow port 22 manually by using the connections field Default: - private subnets of the supplied VPC
