天坑啊！

把手里的盒子升级到debian 13，然后lxc创建了debian 13的容器，安装docker一切都正常

然后部署 portainer ，发现运行正常，但是点击 local 失败 ，“加载失败环境，本地的环境无法访问”

遂复查docker run命令行，发现没问题

之后询问grok及chatgpt

给出的方案不是宿主机lxc权限问题，就是部署命令行的问题。

最后还是查看github找到了答案：加载失败的环境 名为本地的环境无法访问。·波尔泰纳·讨论#12926

Hello everyone, this is a RC release from Docker. We are aware of breaking changes for Docker 29 but please stick to the tested versions of Docker found here -https://docs.portainer.io/start/requirements-and-prerequisites

最终解决方案：

DEFINITIVE SOLUTION: Portainer + Docker Engine v29

🎯 PROBLEM IDENTIFIED

Docker Engine v29 introduced incompatibility with Portainer v2.33.4 due to the minimum API increase from 1.41 to 1.44.

Symptoms:

• ✅ Portainer starts normally
• ❌ Environment "primary" appears as "Down" and "Disconnected"
• ❌ Error: "Failed loading environment - The environment named primary is unreachable"
• 🔍 This can happen on some Cloud VMs: Hetzner, Digital Ocean, AWS EC2, etc.

🔧 IMPLEMENTED SOLUTION

1. Docker Daemon Configuration

Created :/etc/docker/daemon.json

{
  "min-api-version": "1.24",
  "log-driver": "json-file", 
  "log-opts": {
    "max-size": "10m",
    "max-file": "3"
  },
  "features": {
    "containerd-snapshotter": false
  }
}

2. Restart Docker

sudo systemctl restart docker

3. Verify Compatibility

docker version
# Should show: API version 1.52 (minimum version 1.24)
