spec.template.spec.containers.securityContext is not supported

[Dmitriy Gutman]

Hi, I found an issue in k2tf, version 0.2.5.
The spec.template.spec.containers.securityContext is not appears in a result file.

Example:

apiVersion: apps/v1beta1
kind: Deployment
metadata:
  name: metricbeat
  namespace: default
  labels:
    k8s-app: metricbeat
spec:
  template:
    metadata:
      labels:
        k8s-app: metricbeat
    spec:
      serviceAccountName: metricbeat
      containers:
        - name: metricbeat
          image: docker.elastic.co/beats/metricbeat:7.0.0-alpha2
          args: [
            "-c", "/etc/metricbeat.yml",
            "-e",
          ]
          env:
            - name: ELASTICSEARCH_HOST
              value: elastic-service
          securityContext:
            runAsUser: 0

Converting:

k2tf -F -f file.yaml -o output.tf

Result:

resource "kubernetes_deployment" "metricbeat" {
  metadata {
    name      = "metricbeat"
    namespace = "default"
    labels    = { k8s-app = "metricbeat" }
  }
  spec {
    template {
      metadata {
        labels = { k8s-app = "metricbeat" }
      }
      spec {
        container {
          name  = "metricbeat"
          image = "docker.elastic.co/beats/metricbeat:7.0.0-alpha2"
          args  = ["-c", "/etc/metricbeat.yml", "-e"]
          env {
            name  = "ELASTICSEARCH_HOST"
            value = "elastic-service"
          }
        }
        service_account_name = "metricbeat"
      }
    }
  }
}

There no securityContext in converted terraform file.
How it should be:

resource "kubernetes_deployment" "metricbeat" {
  metadata {
    name      = "metricbeat"
    namespace = "default"
    labels    = { k8s-app = "metricbeat" }
  }
  spec {
    template {
      metadata {
        labels = { k8s-app = "metricbeat" }
      }
      spec {
        container {
          name  = "metricbeat"
          image = "docker.elastic.co/beats/metricbeat:7.0.0-alpha2"
          args  = ["-c", "/etc/metricbeat.yml", "-e"]
          env {
            name  = "ELASTICSEARCH_HOST"
            value = "elastic-service"
          }
          security_context {
            run_as_user = 0
          }
        }
        service_account_name = "metricbeat"
      }
    }
  }
}

I also ran into this issue. Please fix.

The issue here is that k2tf skips outputting any attribute that appear to be unset (e.g. empty string or zero value).
In this case run_as_user is 0, so it's deliberately not included in the output. I'm exploring ways to fix this.

Any fix on the reported issue. Getting same error at my end.
