Google Cloud Build: How to increase RAM memory?

Question

How do I increase RAM memory on Google Cloud Build?

I'm getting this error:

Step #1: FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

I'm using the REST API.

I'm trying to find the RAM memory config, but I only found a property called diskSizeInGb. The default for diskSizeInGbis 100GB, and it's just a React app I'm compiling, so I don't think that's the case.

The RAM of the instance is dependant on the machine type you are using, if you need more RAM in your build, you will need to use a different value for machineType.

By default, Cloud Build uses a "n1-standard-1" instance to run the build which has 3.75 GB of memory, however, you can change it to a "n1-highcpu-8" which has double that. You can find the information regarding the instance types over here.

Keep in mind that Cloud Build only accepts "n1-standard-1", "n1-highcpu-8" and "n1-highcpu-32" machines as mentioned in the documentation, and that each has a different billing.

Hope you find this useful!
