Packer plugins to manage existing digitalocean images

Digitalocean image lifecycle

A multi-component packer plugin to manage the lifescycle of existing digitialocean images.

Define your sources, typically you would be using the digitalocean builder then in the build block define the digitalocean-image-lifecycle post-processor:

build {
  sources = ["sources.null.basic-example"]

  post-processor "digitalocean-image-lifecycle" {
    name_prefix = "example-image"
    days_older_than = 9
  }
}

TLDR:

Its worth noting we need to generate the HCL2 of the plugin with a helper. See https://developer.hashicorp.com/packer/guides/hcl/component-object-spec

go install
go generate ./lifecycle/lifecycle.go 
go build
cp packer-plugin-digitalocean-image-lifecycle example

comment out the required_plugins block in example/main.pkr.hcl

cd example
packer init .
packer build .
