# Qwiklabs GCP Architecture Challenge

# Build and Deploy a Docker Image to a Kubernetes Cluster
# https://google.qwiklabs.com/focuses/1738?parent=catalog

# In this hands-on lab you will build a Docker container image 
# using a tag that allows it to be stored on the Google Container 
# Registry (GCR), then push it out to GCR before deploying. 
# Create a Kubernetes cluster and deploy the sample app to the cluster.

# Set ID=[ID_PROJECT]

# Dowload the package
# Alternative can copy the resources from the bucket
# gsutil cp gs://[BUCKET_NAME]/[FILE_NAME] [TARGET_PATH]
gsutil cp gs://$ID/resources-echo-web.tar.gz .

# Go to Cloud Shell

# Upload resource

# Extract resources 
# tar xzvf [FILE_NAME]
tar xzvf resources-echo-web.tar.gz

# Build & push image
# docker build  ------------ build image
# -t [TAG_NAME] ------------ set Tag for image
# [DOCKERFILE_PATH] -------- select Docker file
