### Synchronizing Archives from Docker Container

Starting from v0.5.3, it is supported to synchronize game server archives inside a container without the need for an agent (**temporarily only supports pst deployed in file deployment mode**).
Starting from v0.5.3, it is supported to synchronize game server archives inside a container without the need for an agent.

You only need to change the `SAVE__PATH` environment variable, in the following format:
#### File Deployment Usage

When your pst application is deployed through running a binary file, you just need to modify the `save.path` in `config.yaml`:

```yaml
save:
path: "docker://<container_name_or_id>:<game_save_directory>"
```

For example:

```yaml
save:
path: docker://palworld-server:/palworld/Pal/Saved
# or
save:
path: docker://04b0a9af4288:/palworld/Pal/Saved
```

#### Docker Deployment Usage

If the pst application is deployed as a Docker single container, then you need to modify the `SAVE__PATH` environment variable and mount the Docker daemon inside the pst container.

1. Mount the daemon

In the original `docker run` command, add the line `-v /var/run/docker.sock:/var/run/docker.sock`.

2. Modify the environment variable

Change the `SAVE__PATH` environment variable as follows:

```bash
SAVE__PATH="docker://<container_name_or_id>:<Game Archive Directory>"
SAVE__PATH="docker://<container_name_or_id>:<game_save_directory>"
```

For example:

> [!WARNING]
> If you see an error like `Error response from daemon: client version 1.44 is too new. Maximum supported API version is 1.43` after running, it is because the Docker API version used by your current docker engine is too low. In this case, please add another environment variable:
>
> -e DOCKER_API_VERSION="1.43" (your API version)

> Since the time and location (including HASH) of the Level.sav file created by the game server are uncertain at the first instance, you only need to point to the Saved directory level, and the program will automatically scan.

### 从 docker 容器同步存档

从 v0.5.3 开始,支持无需 agent 同步容器内游戏服务器存档(**暂时只支持以文件部署方式部署的 pst**)
从 v0.5.3 开始,支持无需 agent 同步容器内游戏服务器存档

只需要更改 `SAVE__PATH` 环境变量即可,格式如下:
#### 文件部署使用

当你的 pst 本体是通过运行二进制文件部署时,只需要修改 `config.yaml` 中的 `save.path` 即可:

```yaml
save:
path: "docker://<container_name_or_id>:<游戏存档目录>"
```

比如:

```yaml
save:
path: docker://palworld-server:/palworld/Pal/Saved
# or
save:
path: docker://04b0a9af4288:/palworld/Pal/Saved
```

#### Docker 部署使用

如果 pst 本体是通过 Docker 单体部署的,那么你需要修改 `SAVE__PATH` 环境变量,并且将 Docker 守护进程挂载至 pst 容器内

1. 挂载守护进程

在原来的 `docker run` 命令中,增加一行 `-v /var/run/docker.sock:/var/run/docker.sock`

2. 修改环境变量

更改 `SAVE__PATH` 环境变量,格式如下:

```bash
SAVE__PATH="docker://<container_name_or_id>:<游戏存档目录>"

> [!WARNING]
> 如果在运行后看到如 ` Error response from daemon: client version 1.44 is too new. Maximum supported API version is 1.43` 的报错,是因为你当前 docker engine 使用的 Docker API 版本较低,这时候请再增加一个环境变量:
>

> 由于游戏服务器创建 Level.sav 文件的时间、位置(包含 HASH)在初次都不确定,您只需要指向 Saved 目录级别即可,程序会自动扫描
