#Build-only Overrides

Some settings should differ between building a module and running clones of it. The build phase often needs:

  • Internet access (to install packages from upstream repos).
  • More CPU / RAM (to compile or process faster).

But the resulting clones probably shouldn't:

  • Have internet.
  • Reserve those large resources permanently.

Use buildOverrides to scope settings to the build only:

network:
    vpcs:
        - name: vpc
          internet: false # clones get NO internet
    subnets:
        - name: lan
          vpc: vpc
          cidr: '10.0.0.0/24'

buildOverrides:
    vpcs:
        - name: vpc
          internet: true # build phase only — flip on to install packages
    vms:
        - name: builder
          resources:
              cpu: 8 # build with 8 CPUs
              memory: '16Gi' # and 16Gi memory

vms:
    - name: builder
      source: { url: '...' }
      resources:
          cpu: 2 # clones get 2 CPUs
          memory: '4Gi' # and 4Gi memory
      # ...

The base values in network and vms[].resources are what gets recorded into the module and inherited by clones. buildOverrides only affects this build's own VMs.
