sourceStrategy

env

Represents the environment that will be injected into the build pod.

Configuration

Turn Off SSL Certificate Verification for Git

Add GIT_SSL_NO_VERIFY=true to the environment that will be injected into the build pod:

apiVersion: v1
kind: BuildConfig
spec: 
  ...
  strategy:
     sourceStrategy:
       env:
          - name: GIT_SSL_NO_VERIFY
            value: "true"

Enable a Generic Webhook Trigger

A default build configuration already has a webhook trigger enabled, it is enabled by default when the configuration is created:

apiVersion: v1
kind: BuildConfig
spec:
  triggers:
  - type: Generic
    generic:
      secret: Euf3bjjw

OpenShift will listen for invocations at the following URL: https://openshift.default.svc.cluster.local/oapi/v1/namespaces/<project-name>/buildconfigs/<build-configuration-name>/webhooks/<generic-secret-value>/generic
