gke-gcs-app

This is a 2 part demo. The 1st part, gke-app, shows how to use the kubernetes python client to create a job. The 2nd part, gcs-app, is a simple script to create and upload a file to GCS bucket.

This demo is deployed here

gke-app

The app is a small Flask API with 3 routes:

• /jobs : this is a POST. It takes in one variable number_of_jobs which specifies how many jos to create.

curl -XPOST -d "num_of_jobs=5" https://www.gke-app.gcp.dev.cloudkite.io/jobs
{
  "job_name": "gcs-uploader-140a",
  "message": "Inserted 5 job(s)"
}

• /jobs?job_name=<JOB NAME>: This is a GET. It returns the specified job and it's status.

curl "https://www.gke-app.gcp.dev.cloudkite.io/jobs?job_name=gcs-uploader-f220"
{
  "job_name": "gcs-uploader-f220",
  "job_status": {
    "active": null,
    "completion_time": "Tue, 08 Dec 2020 21:37:31 GMT",
    "failed": null,
    "start_time": "Tue, 08 Dec 2020 21:37:07 GMT",
    "succeeded": 5
  }
}

• /jobs/<NAMESPACE> : This is a GET. It returns a list of all the jobs in a namespace and their status.

curl "https://www.gke-app.gcp.dev.cloudkite.io/jobs/test"
[
  {
    "job_name": "gcs-uploader-7a92",
    "status": "Complete"
  },
  {
    "job_name": "gcs-uploader-7b2b",
    "status": "Complete"
  }
]

gcs-app

The POST method in the gke-app creates a job with the image of the gcs-app. This app creates a file and uploads this file to a GCS bucket.
