Cloud Builder Workflow

This workflow uses Google Cloud Builder to build a go application's source code that lives in Google Cloud Registry into a docker container.

The Steps

Build

The go application's source code is built into a binary using Google Cloud Builder's docker step (read more about steps).

- name: 'gcr.io/cloud-builders/docker'
  args: [ 'build', '-t', 'gcr.io/$PROJECT_ID/docker/test-go-build', '.' ]

Code

This Binary is then imported into a container that is built and pushed to Google Container Registry.

# Build the image
- name: 'gcr.io/cloud-builders/docker'
  args: [ 'build', '-t', 'gcr.io/$PROJECT_ID/docker/test-go', '.' ]
images:
- 'gcr.io/$PROJECT_ID/docker/test-go'

deploy

That image is then used in a deployment in GKE (Google Kubernetes Engine). The entire workflow relies on Google Cloud Builder

steps:
- name: 'gcr.io/cloud-builders/kubectl'
  args:
  - 'set'
  - 'image'
  - 'deployment'
  - 'test-go-cb'
  - 'test-go-cb=gcr.io/$PROJECT_ID/docker/test-go'

Steps

Setup repo

gcloud source repos create test-go
gcloud source repos list
git init
git config credential.helper gcloud.sh
git remote add google \
https://source.developers.google.com/p/[PROJECT_ID]/r/[CLOUD_SOURCE_REPOSITORY_NAME]
git push google master

setup artifacts locations

gsutil mb gs://artifacts-[PROJECT_ID]/

allow your cloud builder to push to GKE

gcloud iam service-accounts describe $PROJECT_ID@cloudbuild.gserviceaccount.com

PROJECT_ID="$(gcloud projects describe \
    $(gcloud config get-value core/project -q) --format='get(projectNumber)')"

gcloud projects add-iam-policy-binding $PROJECT_ID \
    --member=serviceAccount:$PROJECT_ID@cloudbuild.gserviceaccount.com \
    --role=roles/container.developer

run builds
