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.

• In the search box type in and select VM Instances.

• Click on an existing node to see details page, then 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
ssh 123.123.123.123

Starting the Gradle Remote Cache Node

# Install some prerequisite packages
sudo apt update
sudo apt upgrade
sudo apt install openjdk-11-jdk tmux wget
# Create a folder `Workspace` in the home directory.
mkdir Workspace
cd Workspace
mkdir -p data/conf
# using the template in this checkout create config.yaml
vi data/conf/config.yaml
# using the template in this checkout create run_node, replace YOURUSERNAME with your username
vi run_node
chmod +x run_node
mkdir gradle-node
wget https://docs.gradle.com/build-cache-node/jar/build-cache-node-11.1.jar -P gradle-node
# Create a `tmux` session
tmux new -s gradle
sudo ./run_node &
# Detach from the tmux session ctrl+b then d
exit

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

• Open Instance groups in gcloud console
• Click on gradle-remote-cache-group and select Edit Group.
