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.

# Note: To switch projects use `gcloud config set project fetch-licenses`
# Will show the newly created instance
gcloud compute instances list
# Will setup ssh configurations
gcloud compute config-ssh

Starting the Gradle Remote Cache Node

• 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 11 using sudo apt install openjdk-11-jdk.
• Finally run the run_node script using sudo ./run_node from inside the tmux session.
• Detach from the tmux session.

Update the gradle-remote-cache-group instance group.

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