Dockerでホストと同じタイムゾーンをコンテナ起動時に設定する - Qiita

のECS版です。

{
  "family": "test-volumes-from",
  "volumes": [
    {
      "name": "localtime",
      "host": {
        "sourcePath": "/etc/localtime"
      }
    }
  ],
  ...
  "containerDefinitions": [
    {
      ...
      "mountPoints": [
        {
          "sourceVolume": "localtime",
          "containerPath": "/etc/localtime",
          "readOnly": true
        }
      ],
      ...

Task Definitionの volumes でCluster Instance側のパスを指定し、 containerDefinitions 内の各コンテナーの設定の mountPoints でコンテナー側の /etc/localtime に読み取り専用でマウントします。以上。

cp -f -p /usr/share/zoneinfo/Japan /etc/localtime

cat << _EOT_ > /etc/sysconfig/clock

_EOT_

yum install -y ecs-init
echo ECS_CLUSTER=test >> /etc/ecs/ecs.config
sudo service docker start
sudo start ecs
