Simple S3 Resource for Concourse CI

Resource to upload files to S3. Unlike the the official S3 Resource, this Resource can upload or download multiple files.

Usage

Include the following in your Pipeline YAML file, replacing the values in the angle brackets (< >):

resource_types:
- name: <resource type name>
  type: docker-image
  source:
    repository: 18fgsa/s3-resource-simple
resources:
- name: <resource name>
  type: <resource type name>
  source:
    access_key_id: {{aws-access-key}}
    secret_access_key: {{aws-secret-key}}
    bucket: {{aws-bucket}}
    path: [<optional>, use to sync to a specific path of the bucket instead of root of bucket]
    change_dir_to: [<optional, see note below>]
    options: [<optional, see note below>]
    region: <optional, see below>
jobs:
- name: <job name>
  plan:
  - <some Resource or Task that outputs files>
  - put: <resource name>

AWS Credentials

The access_key_id and secret_access_key are optional and if not provided the EC2 Metadata service will be queried for role based credentials.

change_dir_to

The change_dir_to flag lets you upload the contents of a sub-directory without including the directory name as a prefix in your bucket. Given the following directory test:

test
├── 1.json
└── 2.json

and the config:

- name: test
  type: s3-resource-simple
  source:
    change_dir_to: test
    bucket: my-bucket
    [...other settings...]

put will upload 1.json and 2.json to the root of the bucket. By contrast, with change_dir_to set to false (the default), 1.json and 2.json will be uploaded as test/1.json and test/2.json, respectively. This flag has no effect on get or check.

Options

The options parameter is synonymous with the options that aws cli accepts for sync. Please see S3 Sync Options and pay special attention to the Use of Exclude and Include Filters.

Given the following directory test:

test
├── results
│   ├── 1.json
│   └── 2.json
└── scripts
    └── bad.sh

we can upload only the results subdirectory by using the following options in our task configuration:

options:
- "--exclude '*'"
- "--include 'results/*'"

Region

Interacting with some AWS regions (like London) requires AWS Signature Version 4. This options allows you to explicitly specify region where your bucket is located (if this is set, AWS_DEFAULT_REGION env variable will be set accordingly).

region: eu-west-2
