Cloud Run v2 module creating port for second container resulting in error
When deploying multiple containers in a cloud Run service using the resource, the ports assignment assigns a port to the second container.
Deploying a CloudRun service using the TF resource directly
resource "google_cloud_run_v2_service" "default" {
name = "cloudrun-service"
project = "XXXXXXX"
location = "us-central1"
deletion_protection = false
ingress = "INGRESS_TRAFFIC_ALL"
template {
containers {
name = "hello-1"
ports {
container_port = 8080
}
image = "us-docker.pkg.dev/cloudrun/container/hello"
depends_on = ["hello-2"]
}
containers {
name = "hello-2"
image = "us-docker.pkg.dev/cloudrun/container/hello"
env {
name = "PORT"
value = "8081"
}
startup_probe {
http_get {
port = 8081
}
}
}
}
}
The plan in this case is
