Tensorflow Build Pipeline

Tensorflow build pipeline is developed with tekton and openshift pipelines.
These build pipeline executes source build process of tensorflow with different CPU and GPU build parameters.

Setup Environment

The Build environment is currently setup on OpenShift 3.11 cluster.
[tekton-trigger](https://github.com/tektoncd/pipeline/tree/v0.10.2): v0.10.2 is being used for pipelines.

Following commands can be executed to setup similar pipeline of openshift 3.11 cluster:

oc new-project tekton-pipelines
oc adm policy add-scc-to-user anyuid -z tekton-pipelines-controller
oc apply --filename https://storage.googleapis.com/tekton-releases/pipeline/previous/v0.10.2/release.yaml

Additional details for tekton pipeline setup can be found here

Build environment is also setup with tekton trigger.
[tekton-trigger](https://github.com/tektoncd/triggers/tree/v0.3.1): v0.3.1

oc apply --filename https://storage.googleapis.com/tekton-releases/triggers/previous/v0.3.0/release.yaml

Additional details for tekton trigger setup can be found here

Local Testing

1. Setup Tekton Pipeline and Tekton Trigger in cluster. Follow Tekton Pipeline Documentation and Tekton Trigger Documentation

2. Create the resources for the example:

oc apply -f trigger/serviceaccount.yaml
oc apply -f trigger/role.yaml
oc apply -f trigger/binding.yaml
oc apply -f trigger/triggertemplate.yaml
oc apply -f trigger/triggerbinding.yaml
oc apply -f trigger/eventlistener.yaml
oc apply -f trigger/task.yaml
oc apply -f task/buildah.yaml
oc apply -f trigger/pipeline.yaml

3. Send a payload to the listener at port 8080
   port-forwarded with oc port-forward $(oc get pod -o=name -l eventlistener=listener) 8080

curl -X POST \
  http://localhost:8080 \
  -H 'Content-Type: application/json' \
  -H 'X-Hub-Signature: sha1=2da37dcb9404ff17b714ee7a505c384758ddeb7b' \
  -d '{
    "head_commit":
    {
        "id": "r1.14"
    },
    "repository":
    {
        "url": "https://github.com/tensorflow/tensorflow.git",
        "branch": "r1.14"
    }
}'
