Packer (AMI) resource

Concourse resource for Packer that is very much based on this resource by the same name. A new resource was created because the old one has not been maintained in the last 12 months, and the old resource had a tendency to hang.

Source Configuration

• aws_access_key_id: Optional: Access key id if you are passing credentials.
• aws_secret_access_key: Optional: See above.
• aws_session_token: Optional: Use if your access/secret keys are temporary (assumed role/MFA authenticated).
• aws_region: Region where the images of interest live.

Behaviour

check

Not implemented (will just return whatever version was passed to check).

get

Fetches additional metadata about the AMI, in addition to two files:

• id: Plain text file with the AMI ID.
• packer.json: Packer friendly variable file: {"source_ami": "<ami-id>"}.

(I.e. it has the same functionality as the ami-resource.)

put

Build an image using packer after specifing the following parameters:

• template: Path to the Packer template.
• var_file: Optional: Path to external JSON variable file.
• variables: Optional: A map (name: value) of variables that will be passed to Packer.

Example

The following (incomplete) example would build a new AMI using Packer:

resource_types:
- name: packer
  type: docker-image
  source:
    repository: itsdalmo/packer-resource

resources:
- name: concourse-ami
  type: packer
  source:
    aws_access_key_id: ((aws-access-key))
    aws_secret_access_key: ((aws-secret-key))
    aws_session_token: ((aws-session-token))
    aws_region: eu-west-1

jobs:
- name: bake-concourse
  plan:
  - put: concourse-ami
    params:
      template: concourse.json
      var_file:
      - packer/variables.json
      variables:
        environment_tag: development
