Concourse Pipeline Resource

Get and set concourse pipelines from concourse.

Installing

This resource is only compatible with Concourse versions 0.74.0 and higher as no BOSH release is provided. Use this resource by adding the following to the resource_types section of a pipeline config:

---
resource_types:
- name: concourse-pipeline
  type: docker-image
  source:
    repository: robdimsdale/concourse-pipeline-resource
    tag: latest-final

See concourse docs for more details on adding resource_types to a pipeline config.

Using tag: latest-final will pull the latest final release, which can be found on the releases page

To avoid automatically upgrading, use a fixed tag instead e.g. tag: v0.6.3

The docker image is robdimsdale/concourse-pipeline-resource; the images are available on dockerhub.

The rootfs of the docker image is available with each release on the releases page.

The docker image is semantically versioned; these versions correspond to the git tags in this repository.

Source configuration

Check returns the versions of all pipelines. Configure as follows:

---
resources:
- name: my-pipelines
  type: concourse-pipeline
  source:
    target: https://my-concourse.com
    insecure: "false"
    teams:
    - name: team-1
      username: some-user
      password: some-password
    - name: team-2
      username: other-user
      password: other-password

• target: Optional. URL of your concourse instance e.g. https://my-concourse.com. If not specified, the resource defaults to the ATC_EXTERNAL_URL environment variable, meaning it will always target the same concourse that created the container.

• insecure: Optional. Connect to Concourse insecurely - i.e. skip SSL validation. Must be a boolean-parseable string. Defaults to "false" if not provided.

• teams: Required. At least one team must be provided, with the following parameters:

  • name: Required. Name of team. Equivalent of -n team-name in fly login command.

  • username: Required. Basic auth username for logging in to the team. Basic Auth must be enabled for the team.

  • password: Required. Basic auth password for logging in to the team. Basic Auth must be enabled for the team.

in: Get the configuration of the pipelines

Get the config for each pipeline; write it to the local working directory (e.g. /tmp/build/get) with the filename derived from the pipeline name and team name.

For example, if there are two pipelines foo and bar belonging to team-1 and team-2 respectively, the config for the first will be written to team-1-foo.yml and the second to team-2-bar.yml.

resources:
- name: my-pipelines
  type: concourse-pipeline
  source: ...

jobs:
- name: download-my-pipelines
  plan:
  - get: my-pipelines

out: Set the configuration of the pipelines

Set the configuration for each pipeline provided in the params section.

Configuration can be either static or dynamic. Static configuration has the configuration fixed in the pipeline config file, whereas dynamic configuration reads the pipeline configuration from the provided file.

One of either static or dynamic configuration must be provided; using both is not allowed.

static

---
resources:
- name: my-pipelines
  type: concourse-pipeline
  source:
    teams:
    - name: team-1

jobs:
- name: set-my-pipelines
  plan:
  - put: my-pipelines
    params:
      pipelines:
      - name: my-pipeline
        team: team-1
        config_file: path/to/config/file
        vars_files:
        - path/to/optional/vars/file/1
        - path/to/optional/vars/file/2

• pipelines: Required. Array of pipelines to configure. Must be non-nil and non-empty. The structure of the pipeline object is as follows:

• name: Required. Name of pipeline to be configured. Equivalent of -p my-pipeline-name in fly set-pipeline command.

• team: Required. Name of the team to which the pipeline belongs. Equivalent of -n my-team in fly login command. Must match one of the teams provided in source.

• config_file: Required. Location of config file. Equivalent of -c some-config-file.yml in fly set-pipeline command.

• vars_files: Optional. Array of strings corresponding to files containing variables to be interpolated via {{ }} in config_file. Equivalent of -l some-vars-file.yml in fly set-pipeline command.

dynamic

Resource configuration as above for Check, with the following job configuration:

---
jobs:
- name: set-my-pipelines
  plan:
  - put: my-pipelines
    params:
      pipelines_file: path/to/pipelines/file

• pipelines_file: Required. Path to dynamic configuration file. The contents of this file should have the same structure as the static configuration above, but in a file.

Developing

Prerequisites

A valid install of golang >= 1.6 is required.

Dependencies

Dependencies are vendored in the vendor directory, according to the golang 1.5 vendor experiment.

Updating dependencies

Install gvt and make sure it is available in your $PATH, e.g.:

go get -u github.com/FiloSottile/gvt

To add a new dependency:

gvt fetch

To update an existing dependency to a specific version:

gvt delete <import_path>
gvt fetch -revision <revision_number> <import_path>

Running the tests

Install the ginkgo executable with:

go get -u github.com/onsi/ginkgo/ginkgo

The tests require a concourse API server to test against, and a valid basic auth username/password for that concourse deployment.

Run the tests with the following command:

TARGET=https://my-concourse.com \
USERNAME=my-basic-auth-user \
PASSWORD=my-basic-auth-password \
./bin/test

Contributing

Please make all pull requests to the develop branch, and ensure the tests pass locally.
