itsdalmo/packer-resource repository overview

⁠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
