You can have a provider image with the following steps:

export DOCKER_REGISTRY=<YOUR_DOCKERHUB_USERNAME>
export PLATFORMS=linux_amd64

make build publish
# Command will finish as below
# ...
# 13:19:48 [ .. ] docker build build-5090d4e0/provider-jet-gcp-controller-amd64
# sha256:0744c8a22c60d65d0dfed56340d585829a7c1b62a0043761f2cdf8c5830fd438
# 13:20:00 [ OK ] docker build build-5090d4e0/provider-jet-gcp-controller-amd64
# 13:20:01 [ .. ] docker build <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp-amd64:v0.3.0-rc.14.gcc2574e
# 13:20:01 [ OK ] docker build <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp-amd64:v0.3.0-rc.14.gcc2574e
# 13:20:01 [ .. ] docker build <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp-controller-amd64:v0.3.0-rc.14.gcc2574e
# 13:20:12 [ OK ] docker build <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp-controller-amd64:v0.3.0-rc.14.gcc2574e

# Remove "-amd64" part from image names
docker tag <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp-amd64:v0.3.0-rc.14.gcc2574e <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp:v0.3.0-rc.14.gcc2574e
docker tag <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp-controller-amd64:v0.3.0-rc.14.gcc2574e <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp-controller:v0.3.0-rc.14.gcc2574e

docker push <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp:v0.3.0-rc.14.gcc2574e
docker push <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp-controller:v0.3.0-rc.14.gcc2574e

Now you can install the custom-built provider with:

kubectl crossplane install provider <YOUR_DOCKERHUB_USERNAME>/provider-jet-gcp:v0.3.0-rc.14.gcc2574e

Could you please also add an example manifest for folder resource?

Merging this since it is a configuration change that we need to do anyway and there seems to be no side effect.
