    ulimits:
{% if container.ulimits.nproc is defined %}
      nproc: {{ container.ulimits.nproc }}
{% endif %}
{% if container.ulimits.nofile is defined %}
      nofile:
{% for param, value in container.ulimits.nofile.items() %}
        {{ param }}: {{ value }}
{% endfor %}
{% endif %}
{% endif %}
