Terraform setup

Create service account credentials for running terraform locally. Then

export GOOGLE_CREDENTIALS=<PATH TO SERVICE ACCOUNT JSON CREDS>
gcloud auth activate-service-account --key-file $GOOGLE_CREDENTIALS
terraform init

Terraform service account, Editor role was not enough

• to set cloud run service to noauth, had to add Security Admin on camunda cloud run resource (NOT PROJECT level)

Docker / gcloud Setup

For mac I needed to expose the docker deamon on a tcp port:-

docker run -d -v /var/run/docker.sock:/var/run/docker.sock -p 127.0.0.1:1234:1234 bobrik/socat TCP-LISTEN:1234,fork UNIX-CONNECT:/var/run/docker.sock

Then in bash_profile:

export DOCKER_HOST=tcp://localhost:1234

Also needed to setup GCR creds in docker

gcloud auth configure-docker
