amazon-web-services - 在AWS-ECS Docker容器上扩展根分区

Question

默认情况下，如何扩展某个任务定义的所有容器的根分区？如果它扩展了实例或群集中的所有容器(包括ECS Agent)，那仍然可以。

阅读https://docs.aws.amazon.com/AmazonECS/latest/developerguide/bootstrap_container_instance.html之后，我尝试添加#cloud-boothook
cloud-init-per once docker_options echo 'OPTIONS="${OPTIONS} --storage-opt dm.basesize=25G"' >> /etc/sysconfig/docker到自动缩放组的高级详细信息，但无济于事。

我还尝试了以下所有尝试(均未成功)(在同一位置):
sed -i '/^EXTRA_DOCKER_STORAGE_OPTIONS/s/"$/ --storage-opt dm.basesize=25G"/' /etc/sysconfig/docker-storage-setupsed -i '/^DOCKER_STORAGE_OPTIONS/s/"$/ --storage-opt dm.basesize=25G"/' /etc/sysconfig/docker-storage
和sed -i '/^OPTIONS/s/"$/ --storage-opt dm.basesize=25G"/' /etc/sysconfig/docker
他们都没有工作。

我尝试将ECS-Agent从1.18更新到1.23。
这些解决方案在两个版本上均失败。

Answer 1

原来我与之前的一些尝试很接近:

我犯了一个错误，没有在 #cloud-boothook上方添加#! /bin/bash行。

然后我在sed -i '/^OPTIONS/s/"$/ --storage-opt dm.basesize=25G"/' /etc/sysconfig/docker之后添加了cloud-init-per once docker_options行

所以最终看起来像:
#cloud-boothook#! /bin/bashcloud-init-per once docker_options sed -i '/^OPTIONS/s/"$/ --storage-opt dm.basesize=25G"/' /etc/sysconfig/docker
那行得通。
