在ECS Fargate部署ArangoDB集群遇arangod缺失错误的求助

我尝试用默认的arangodb/arangodb-starter容器在ECS中创建ArangoDB集群，但启动Fargate类型的ECS任务时，日志报错/usr/sbin/arangod未找到。

操作流程：通过docker pull拉取该镜像，按ECR推送命令打标签后推送到ECR，创建Fargate任务并启动服务，容器启动后日志输出如下：

|INFO| Starting arangodb version 0.15.5, build 7832707 component=arangodb

[ERROR| Cannot find arangod (expected at /usr/sbin/arangod). component=arangodb

How to solve this:

1 - Install ArangoDB locally or run the ArangoDB starter in docker. (see README for details).

本地运行同标签容器一切正常，为何ECS中无法运行？

补充：ECS任务定义

• 镜像类型误用：arangodb/arangodb-starter是集群管理启动器，本身不含arangod二进制文件。它的作用是编排ArangoDB节点容器，而非直接运行数据库服务。本地运行可能因额外挂载或配置掩盖了问题，ECS中直接启动则暴露此核心问题。
• 替换为标准服务镜像：将任务定义中的镜像改为arangodb/arangodb（这是包含完整ArangoDB服务的镜像），即可正常启动单个数据库节点。
• 若需用starter搭建集群：需在容器command字段添加集群启动参数，例如：

  ["--starter.mode=cluster", "--starter.address=$(curl -s $ECS_CONTAINER_METADATA_URI_V4 | jq -r '.Networks[0].IPv4Addresses[0]')"]
  

  同时要注意：Fargate不支持host类型卷，需将存储替换为EFS卷；确保任务角色有权限访问ECS元数据服务（Fargate默认支持）。
• 验证镜像一致性：本地直接运行ECR中的镜像（不带任何额外参数）：docker run 123456789.dkr.ecr.eu-west-1.amazonaws.com/arangodb:latest，确认是否同样报错，排查镜像推送是否正确。
