Concourse Pipeline Resource

Get and set concourse pipelines from concourse.

Installing

Use this resource by adding the following to the resource_types section of a pipeline config:

urce_types:
me: concourse-pipeline
pe: docker-image
urce:
repository: concourse/concourse-pipeline-resource

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

Source configuration

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

urces:
me: my-pipelines
pe: concourse-pipeline
urce:
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: Basic auth username for logging in to the team. If this and password are blank, team must have no authentication configured.

• password: Basic auth password for logging in to the team. If this and username are blank, team must have no authentication configured.

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.

urces:
me: my-pipelines
pe: concourse-pipeline
urce: ...

:
me: download-my-pipelines
an:
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

urces:
me: my-pipelines
pe: concourse-pipeline
urce:
teams:
- name: team-1

:
me: set-my-pipelines
an:
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.

• unpaused: Optional. Boolean specifying if the pipeline should be unpaused after the creation. If it is set to true, the command unpause-pipeline will be executed for the specific pipeline.

dynamic

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

:
me: set-my-pipelines
an:
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

• golang is required - version 1.9.x is tested; earlier versions may also work.
• docker is required - version 17.06.x is tested; earlier versions may also work.

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.:

et -u github.com/FiloSottile/gvt

To add a new dependency:

fetch

To update an existing dependency to a specific version:

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

Running the tests

Install the ginkgo executable with:

et -u github.com/onsi/ginkgo/ginkgo

The tests require a running Concourse configured with basic auth to test against.

Run the tests with the following command (optionally also setting INSECURE=true):

LOCATION=path/to/fly \
ET=https://my-concourse.com \
NAME=my-basic-auth-user \
WORD=my-basic-auth-password \
n/test

or with the Dockerfile…

The tests have been embedded with the Dockerfile; ensuring that the testing environment is consistent across any docker enabled platform. When the docker image builds, the test are run inside the docker container, on failure they will stop the build.

Run the tests with the following command:

er build -t concourse-pipeline-resource .

Contributing

Please ensure the tests pass locally.
