I am deploying containers via AWS Fargate but I am running into "No Space left on device". Is there a way I can specify the volume size in task_definitions:
task_size:
mem_limit: 2GB
cpu_limit: 256
As of Fargate platform 1.4, released on 04/2020, ephemeral storage is now 20 GB, instead of 10 GB. Additionally, you can now mount persistent EFS storage volumes in Fargate tasks.
For example:
{
"containerDefinitions": [
{
"name": "container-using-efs",
"image": "amazonlinux:2",
"entryPoint": [
"sh",
"-c"
],
"command": [
"ls -la /mount/efs"
],
"mountPoints": [
{
"sourceVolume": "myEfsVolume",
"containerPath": "/mount/efs",
"readOnly": true
}
]
}
],
"volumes": [
{
"name": "myEfsVolume",
"efsVolumeConfiguration": {
"fileSystemId": "fs-1234",
"rootDirectory": "/path/to/my/data",
"transitEncryption": "ENABLED",
"transitEncryptionPort": integer,
"authorizationConfig": {
"accessPointId": "fsap-1234",
"iam": "ENABLED"
}
}
}
]
}
Taken from: efs-volumes in Fargate
You can now increase your fargate ephemeral storage to 200GB in task definition. Therefore with this there is no need to attach the volume unless you need a storage of larger than 200GB.
"ephemeralStorage": {
"sizeInGiB": 200
}
