ibm-container-resource

A concourse resource for managing IBM Container Service version number.

Source Configuration

• uri: Optional. The IBM Container Service versions URI. If not specified, the resource will use https://containers.bluemix.net/v1/kube-versions. If specified, it overwrites environment setting.

• environment: Optional. The environment of IBM Container Service. If not specified, the resource will check version of production environment.

• type: Optional. Default default. If not specified, the resource will check default version.

• version: Optional. The version number to check. If specified, the resource will only detect version that greater than or equal this version.

Example

Resource configuration for a staging environment of IBM Container Service:

resource_types:
- name: ibm-container
  type: docker-image
  source:
    repository: bluebosh/ibm-container-resource
    tag: latest

resources:
- name: ibm-container-stage
  type: ibm-container
  source:
    environment: stage1
    version: 1.7.16

jobs:
- name: check-ibm-container-version
  plan:
  - aggregate:
    - get: ibm-container-stage
      trigger: true
  - task: get-ibm-container-version
    config:
      platform: linux
      image_resource: { type: docker-image, source: { repository: bluebosh/ibm-container-resource, tag: latest } }
      inputs:
      - name: ibm-container-stage
      run:
        path: /bin/bash
        args:
        - -c
        - |
          #!/bin/bash
          cat ibm-container-stage/number

Behavior

check: Report the current version number.

Detects new version by fetching from the container service endpoint. If the type is latest, it returns latest version. If the type is oldest, it returns oldest version. If the type is other value, it returns default version. And this version should be equal to or greater than the version, otherwise it returns no version.

in: Provide the version as a file.

Provides the version number to the build as a version file in the destination.

Can be configured to bump the version locally, which can be useful for getting the final version ahead of time when building artifacts.
