|
|
- `spot_instance_types` (array of strings) - a list of acceptable instance
|
|
|
|
|
types to run your build on. We will request a spot instance using the max
|
|
|
|
|
price of `spot_price` and the allocation strategy of "lowest price".
|
|
|
|
|
Your instance will be launched on an instance type of the lowest available
|
|
|
|
|
price that you have in your list. This is used in place of instance_type.
|
|
|
|
|
You may only set either spot_instance_types or instance_type, not both.
|
|
|
|
|
This feature exists to help prevent situations where a Packer build fails
|
|
|
|
|
because a particular availability zone does not have capacity for the
|
|
|
|
|
specific instance_type requested in instance_type.
|
|
|
|
|
|
|
|
|
|
- `spot_price` (string) - The maximum hourly price to pay for a spot instance
|
|
|
|
|
to create the AMI. Spot instances are a type of instance that EC2 starts
|
|
|
|
|
when the current spot price is less than the maximum price you specify.
|
|
|
|
|
Spot price will be updated based on available spot instance capacity and
|
|
|
|
|
current spot instance requests. It may save you some costs. You can set
|
|
|
|
|
this to `auto` for Packer to automatically discover the best spot price or
|
|
|
|
|
to "0" to use an on demand instance (default).

|
|
|
- `spot_price_auto_product` (string) - Deprecated. Prior to v1.4.3, was
|
|
|
|
|
required if `spot_price` is set to `auto`.
|
|
|
|
|
|
|
|
|
|
If you are using Packer v1.4.3 or later, simply remove this from your
|
|
|
|
|
template; it is no longer necessary based on recent changes to how Amazon
|
|
|
|
|
calculates spot prices.
|
|
|
|
|
|
|
|
|
|
Prior to version 1.4.3, This told Packer what sort of AMI you're launching
|
|
|
|
|
to find the best spot price. This must be one of: `Linux/UNIX`, `SUSE Linux`,

|
|
|
`Windows`, `Linux/UNIX (Amazon VPC)`, `SUSE Linux (Amazon VPC)`,
|
|
|
|
|
`Windows (Amazon VPC)`
|
|
|
|
|
|
|
|
|
|
- `spot_tags` (object of key/value strings) - Requires `spot_price` to be
|
|
|
|
|
set. This tells Packer to apply tags to the spot request that is issued.
