几天来，我一直在 Red Hat Enterprise Linux 8.2 (LVM) - Gen2 上使用 podman 作为 Docker 替代方案。
我正在尝试安装 LogStash、OpenSearch 和 OpenSearch Dashboards，过去我在 Docker 桌面（操作系统：Win10/WSL2：Kali Linux）上成功安装了它。
看来我无法通过 RHEL 8.2 上的 dockerfile，在那里我提取了以下图像：

我安装了 python 3 库podman-compose，但是当我运行它时遇到了很多错误podman compose up，我最终认为我必须这样做export PATH="$PATH:~/.local/bin:/usr/local/bin"才能使用podman-compose。
这样做之后，我跑了 podman-compose up，结果如下：
['podman', '--version', '']
using podman version: 1.6.4
Traceback (most recent call last):

所以我用 定义了一个项目名称opensearch-dashboards，podman-compose -p opensearch-dashboards up但我得到了另一个错误堆栈跟踪：

老实说，我不知道。
