CannotPullContainerError: no space left on device

Question

Since today I have been seeing several failures on batch jobs due to the following error:

```
CannotPullContainerError: failed to register layer: Error processing tar file(exit status 1): write /opt/conda/lib/libmkl_avx512.so: no space left on device
```

I am using the standard AWS ECS AMI, and my compute environment is set up to use 'm4 family' so I would expect it to choose an instance that has enough resources.  
  
Is there anything I can do to prevent this?

Answer

Thanks Anish, that helped.  For anyone also having trouble with this, you need to  
1) increase the size of the disk available to docker (/dev/xvdcz) in the launch template  
2) increase the disk quota available to each container in the launch template, I used:

```
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="==BOUNDARY=="

--==BOUNDARY==
Content-Type: text/cloud-boothook; charset="us-ascii"
#cloud-boothook
#!/bin/bash
cloud-init-per once docker_options echo 'OPTIONS="${OPTIONS} --storage-opt dm.basesize=30G"' >> /etc/sysconfig/docker

--==BOUNDARY==
Content-Type: text/x-shellscript; charset="us-ascii"

#!/bin/bash
# more aggressive settings for cleaning up old tasks
echo ECS_ENGINE_TASK_CLEANUP_WAIT_DURATION=1m >> /etc/ecs/ecs.config
echo ECS_IMAGE_CLEANUP_INTERVAL=1m >> /etc/ecs/ecs.config
echo ECS_IMAGE_MINIMUM_CLEANUP_AGE=1m >> /etc/ecs/ecs.config

--==BOUNDARY==--
```

Answer

Hello,  
  
In order to fix this issue, you need to update the dm.base value in the docker configuration. Please refer this article to achieve the same.
