Use AllocateHosts with a CLI

The following code examples show how to use AllocateHosts.

CLI
Amazon CLI

Example 1: To allocate a Dedicated Host

The following allocate-hosts example allocates a single Dedicated Host in the eu-west-1a Availability Zone, onto which you can launch m5.large instances. By default, the Dedicated Host accepts only target instance launches, and does not support host recovery.

aws ec2 allocate-hosts \ --instance-type m5.large \ --availability-zone eu-west-1a \ --quantity 1

Output:

{ "HostIds": [ "h-07879acf49EXAMPLE" ] }

Example 2: To allocate a Dedicated Host with auto-placement and host recovery enabled

The following allocate-hosts example allocates a single Dedicated Host in the eu-west-1a Availability Zone with auto-placement and host recovery enabled.

aws ec2 allocate-hosts \ --instance-type m5.large \ --availability-zone eu-west-1a \ --auto-placement on \ --host-recovery on \ --quantity 1

Output:

{ "HostIds": [ "h-07879acf49EXAMPLE" ] }

Example 3: To allocate a Dedicated Host with tags

The following allocate-hosts example allocates a single Dedicated Host and applies a tag with a key named purpose and a value of production.

aws ec2 allocate-hosts \ --instance-type m5.large \ --availability-zone eu-west-1a \ --quantity 1 \ --tag-specifications 'ResourceType=dedicated-host,Tags={Key=purpose,Value=production}'

Output:

{ "HostIds": [ "h-07879acf49EXAMPLE" ] }
