When a plugin is installed we may want to check the license and make users agree. We may also want to unpack the given plugin in a particular location.

    int size = thisList.size();
    if (size != otherList.size()) {
      return false;
    }
    if (thisList instanceof RandomAccess && otherList instanceof RandomAccess) {
      // avoid allocation and use the faster loop
      for (int i = 0; i < size; i++) {
        if (!Objects.equals(thisList.get(i), otherList.get(i))) {
          return false;
        }
      }
      return true;

它可以是直接的 **Docker**、**Docker Compose**、**Kubernetes**、某个**云服务**等。

在大多数（或全部）情况下，都有简单选项可以在开机时运行容器并在失败时启用重启。例如，在 Docker 中是命令行选项 `--restart`。

如果不使用容器，要让应用开机自启并带重启可能繁琐且困难。但在**容器**场景下，这种功能通常默认就包含了。✨

## 复制 - 进程数 { #replication-number-of-processes }

如果你有一个由 **Kubernetes**、Docker Swarm Mode、Nomad 或其他类似的复杂系统管理的、在多台机器上运行的分布式容器<dfn title="被配置为以某种方式连接并协同工作的多台机器">集群</dfn>，那么你很可能会希望在**集群层面**来**处理复制**，而不是在每个容器中使用**进程管理**（比如让 Uvicorn 运行多个 workers）。
