Install CloudStor plugin on Amazon ECS Optimized AMI Instance

ecs-cloudstor-install.sh

#!/bin/bash

set -ex

if [ $# -ne 2 ]; then
        echo "Usage: $0 EFS_ID_REGULAR EFS_ID_MAXIO"
        exit 1
fi

EFS_ID_REGULAR=$1
EFS_ID_MAXIO=$2

AWS_REGION="$(cat /etc/yum/vars/awsregion)"
DOCKER_VERSION=$(docker version | awk '/^Server/{f=1} $1 ~ /Version:/ {if(f) {print $2}}')
CLOUDSTOR_REPO="docker4x/cloudstor"
CLOUDSTOR_TAG="${DOCKER_VERSION}-aws1"

docker plugin install \
        --alias cloudstor:aws \
        --grant-all-permissions\
        ${CLOUDSTOR_REPO}:${CLOUDSTOR_TAG} \
        CLOUD_PLATFORM=AWS EFS_ID_REGULAR=${EFS_ID_REGULAR} EFS_ID_MAXIO=${EFS_ID_MAXIO} AWS_REGION=${AWS_REGION} EFS_SUPPORTED=1 DEBUG=1

service docker restart might be needed afterwards... not entirely sure though.

Useful tools for EFS, but not necessary for this purpose is in the package amazon-efs-utils. It contains a watchdog agent though that may be useful.

backing	Use “shared” for EFS volumes, “relocatable” for EBS volumes.
