      "services:\n  <service>:\n    healthcheck:\n      test: [\"CMD\", \"curl\", \"-f\", \"http://localhost\"]\n      interval: 1m30s\n      timeout: 10s\n      retries: 3\n      start_period: 40s"

      "Version: v2.3.1",
      "healthcheck.test: Command used to check health; a string or list. A list begins with `NONE`, `CMD`, or `CMD-SHELL`; a string is equivalent to `CMD-SHELL` followed by that string.",
      "healthcheck.interval: Duration between checks.",
      "healthcheck.timeout: Duration before a check is considered failed.",
      "healthcheck.retries: Number of consecutive failures needed to report the container unhealthy.",
      "healthcheck.start_period: Duration to wait during container initialization before counting failures toward the retry threshold.",
      "healthcheck.start_interval: Duration between checks during the start period. nerdctl v2.3.1 lists this field as unimplemented.",
