OCI runtime exec failed: exec failed: unable to start container process: exec: "mongosh": executable file not found in $PATH: unknown

OCI (Open Container Initiative) runtime error occurs when a system is trying to execute a command within a container but encounters an issue. In this case, the error specifically says "exec: 'mongosh': executable file not found in $PATH". This means that the command `mongosh`, which is part of MongoDB's shell utility for interacting with a cluster, cannot be found in the directory search path (`$PATH`) of the container.

To resolve this problem:

1. **确认安装**: 确保`mongosh`已经安装在容器镜像内。如果是基础镜像里没有包含这个工具，需要从MongoDB官方仓库拉取包含`mongosh`的镜像。

2. **设置环境变量**: 在Dockerfile或container configuration中添加路径信息，指定`mongosh`的位置，如`ENV PATH /path/to/mongosh:$PATH`。

3. **运行命令时提供完整路径**: 如果镜像确实有`mongosh`但不在默认路径下，可以尝试通过绝对路径来运行它，例如 `docker exec -it <container_id> /path/to/mongosh`.

4. **检查权限**: 确保运行该命令的用户在容器中拥有执行`mongosh`的权限。
