Related Issue(s)

Fixes #8223

How to test

Step 1: Get the current installer:

docker create -ti --name installer eu.gcr.io/gitpod-core-dev/build/installer:main.2486
docker cp installer:/app/installer ./installer
docker rm -f installer
./installer init > gitpod.config.yaml

Step 2: Add

experimental:
  IDEConfig:

to the Gitpod config and run

$ ./installer render --danger-use-unsupported-config --config gitpod.config.yaml > gitpod.yaml

You get:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x1a3d056]

Step 3: Get the installer of this PR:

docker create -ti --name installer eu.gcr.io/gitpod-core-dev/build/installer:corneliusludmann-installer-fix-8223.0
docker cp installer:/app/installer ./installer
docker rm -f installer

run

$ ./installer render --danger-use-unsupported-config --config gitpod.config.yaml > gitpod.yaml

Should work without errors.

Bonus points for setting proper workspace CPULimits and testing if it still renders as it should.
