在 AWS ECS 容器上挂载 S3 存储桶作为文件系统 [英] Mount S3 bucket as filesystem on AWS ECS container

问题描述

我正在尝试使用 rexray/s3fs 驱动程序将 S3 作为卷挂载到 AWS ECS docker 容器上.

I am trying to mount S3 as a volume on AWS ECS docker container using rexray/s3fs driver.

我可以在我安装了插件的本地机器上执行此操作

I am able to do this on my local machine, where I installed plugin

$docker plugin install rexray/s3fs

并在 docker 容器上安装 S3 存储桶.

and mounted S3 bucket on docker container.

$docker plugin ls

ID                  NAME                 DESCRIPTION                                   ENABLED

3a0e14cadc17        rexray/s3fs:latest   REX-Ray FUSE Driver for Amazon Simple Storage   true 

$docker run -ti --volume-driver=rexray/s3fs -v s3-bucket:/data img

我正在尝试在 AWS ECS 上复制它.

I am trying replicate this on AWS ECS.

尝试遵循以下文档:https://docs.aws.amazon.com/AmazonECS/latest/developerguide/docker-volumes.html

如果我给 Driver 值，那么任务将无法运行并给出无法放置任务，因为没有容器实例满足其所有要求."错误.

If I give Driver value then task is not able to run and giving "was unable to place a task because no container instance met all of its requirements." error.

我正在使用 t2.medium 实例并为其提供任务要求，因此它不应该是硬件要求问题.

I am using t2.medium instance and giving of it requirement for task so it should not be H/W requirement issue.

如果我从作业定义中删除驱动程序配置，任务将被执行.

If I remove the Driver config from Job definition task gets executed.

似乎我错过了配置某些东西.

It seems I am miss configuring something.

有没有人尝试/尝试过同样的事情，请分享知识.

Is anyone trying/tried same thing, please share the knowledge.

谢谢！！

推荐答案

您使用 rexray/s3fs 驱动程序的方法是正确的.

Your approach of using the rexray/s3fs driver is correct.

这些是我在 Amazon Linux 1 上运行的步骤.

These are the steps I followed to get things working on Amazon Linux 1.

首先您需要安装 s3fs.

First you will need to install s3fs.

yum install -y gcc libstdc+-devel gcc-c+ fuse fuse-devel curl-devel libxml2-devel mailcap automake openssl-devel git gcc-c++
git clone https://github.com/s3fs-fuse/s3fs-fuse
cd s3fs-fuse/
./autogen.sh
./configure --prefix=/usr --with-openssl
make
make install

现在安装驱动程序.这里有一些您可能想要修改的选项，例如使用 IAM 角色而不是访问密钥和 AWS 区域.

Now install the driver. There are some options here you might want to modify such as using an IAM role instead of Access Key and AWS region.

docker plugin install rexray/s3fs:latest S3FS_REGION=ap-southeast-2 S3FS_OPTIONS="allow_other,iam_role=auto,umask=000" LIBSTORAGE_INTEGRATION_VOLUME_OPERATIONS_MOUNT_ROOTPATH=/ --grant-all-permissions

现在是重启ECS代理非常重要的一步.我也会更新以进行良好的衡量.

Now the very important step of restarting the ECS agent. I also update for good measure.

yum update -y ecs-init
service docker restart && start ecs

您现在应该可以创建您的任务定义了.重要的部分是您的音量配置，如下所示.

You should now be ready to create your task definition. The important part is your volume configuration which is shown below.

"volumes": [
  {
    "name": "name-of-your-s3-bucket",
    "host": null,
    "dockerVolumeConfiguration": {
      "autoprovision": false,
      "labels": null,
      "scope": "shared",
      "driver": "rexray/s3fs",
      "driverOpts": null
    }
  }
]

现在你只需要在容器定义中指定挂载点:

Now you just need to specify the mount point in the container definition:

"mountPoints": [
  {
    "readOnly": null,
    "containerPath": "/where/ever/you/want",
    "sourceVolume": "name-of-your-s3-bucket"
  }
]

现在，只要您拥有访问 s3 存储桶的适当 IAM 权限，您的容器就应该启动，并且您可以继续使用 s3 作为卷.

Now as long as you have appropriate IAM permissions for accessing the s3 bucket your container should start and you can get on with using s3 as a volume.

如果您在运行ATTRIBUTE"任务时遇到错误，请仔细检查插件是否已成功安装在 ec2 实例上并且 ecs 代理已重新启动.还要仔细检查您的驱动程序名称是rexray/s3fs".

If you get an error running the task that says "ATTRIBUTE" double check that the plugin has been successfully installed on the ec2 instance and the ecs agent has been restarted. Also double check your driver name is "rexray/s3fs".
