# Deployment with Kubernetes
# KUBE_CA_PEM_FILE is the path of a certificate file. It automatically set by GitLab
# if you enable Kubernetes integration in a project.
#
# As of this writing, Kubernetes integration can not be set on a group level, so it has to
# be manually set in every project.
# Alternatively, we use a custom KUBE_CA_BUNDLE environment variable, which can be set at
# the group level. In this case, the variable contains the whole content of the certificate,
# which we dump to a temporary file
#
# Check if the KUBE_CA_PEM_FILE exists. Otherwise, create it from KUBE_CA_BUNDLE
