Setting up the Gradle Build Cache Node on Google Cloud Platform.

To setup the Gradle Remote Cache you need to do the following:

Create a new Instance

Open the Cloud Platform console.
Select Compute Engine Instances.
Click on an existing node, and use Create Similar to create a new node. Note: This node has to be tagged with a network tag called gradle-remote-cache-node for it to be picked up by the load balancer. Make sure you create the node in the zone us-east-1-b.
Click Allow HTTP Traffic and Allow HTTPs Traffic. By doing do, you are allowing UberProxy access to the remote cache. The load balancer is only available when you are on a corp network.
Connect to the newly created node using an SSH session. You can use the gcloud CLI for this. Note: Use the external IP of the newly created node to SSH.

# Will show the newly created instance
gcloud compute instances list
# Will setup ssh configurations
gcloud compute config-ssh

Create a folder Workspace in the home directory.
Copy the contents of this folder, into the Workspace folder. Remove the .empty file from the data folder.
Download the build cache jar and copy it into the gradle-node folder.
Create a tmux session using tmux new -s gradle.
Run chmod +x ~/Workspace/run_node.
Install JDK 8 using sudo apt install openjdk-8-jdk.
Finally run the run_node script using sudo ./run_node from inside the tmux session.
Detach from the tmux session.

Add the newly created node, to the instance group by using Edit instance group.
Select the node, from the drop-down list.
Click Save.
