Right this moment we’re asserting that Amazon Elastic Container Service (Amazon ECS) helps an integration with Amazon Elastic Block Retailer (Amazon EBS), making it simpler to run a wider vary of information processing workloads. You possibly can provision Amazon EBS storage in your ECS duties working on AWS Fargate and Amazon Elastic Compute Cloud (Amazon EC2) without having to handle storage or compute.
Many organizations select to deploy their functions as containerized packages, and with the introduction of Amazon ECS integration with Amazon EBS, organizations can now run extra sorts of workloads than earlier than.
You possibly can run information workloads requiring storage that helps excessive transaction volumes and throughput, equivalent to extract, remodel, and cargo (ETL) jobs for large information, which have to fetch current information, carry out processing, and retailer this processed information for downstream use. As a result of the storage lifecycle is totally managed by Amazon ECS, you don’t have to construct any further scaffolding to handle infrastructure updates, and in consequence, your information processing workloads are actually extra resilient whereas concurrently requiring much less effort to handle.
Now you possibly can select from a wide range of storage choices in your containerized functions working on Amazon ECS:
- Your Fargate duties get 20 GiB of ephemeral storage by default. For functions that want further space for storing to obtain giant container pictures or for scratch work, you possibly can configure as much as 200 GiB of ephemeral storage in your Fargate duties.
- For functions that span many duties that want concurrent entry to a shared dataset, you possibly can configure Amazon ECS to mount the Amazon Elastic File System (Amazon EFS) file system to your ECS duties working on each EC2 and Fargate. Widespread examples of such workloads embrace internet functions equivalent to content material administration techniques, inside DevOps instruments, and machine studying (ML) frameworks. Amazon EFS is designed to be accessible throughout a Area and could be concurrently connected to many duties.
- For functions that want high-performance, low-cost storage that doesn’t must be shared throughout duties, you possibly can configure Amazon ECS to provision and fasten Amazon EBS storage to your duties working on each Amazon EC2 and Fargate. Amazon EBS is designed to offer block storage with low latency and excessive efficiency inside an Availability Zone.
To study extra, see Utilizing information volumes in Amazon ECS duties and protracted storage finest practices within the AWS documentation.
Getting began with EBS quantity integration to your ECS duties
You possibly can configure the quantity mount level in your container within the activity definition and cross Amazon EBS storage necessities in your Amazon ECS activity at runtime. For many use circumstances, you will get began by merely offering the dimensions of the quantity wanted for the duty. Optionally, you possibly can configure all EBS quantity attributes and the file system you need the quantity formatted with.
1. Create a activity definition
Go to the Amazon ECS console, navigate to Activity definitions, and select Create new activity definition.
Within the Storage part, select Configure at deployment to set EBS quantity as a brand new configuration kind. You possibly can provision and fasten one quantity per activity for Linux file techniques.
While you select Configure at activity definition creation, you possibly can configure current storage choices equivalent to bind mounts, Docker volumes, EFS volumes, Amazon FSx for Home windows File Server volumes, or Fargate ephemeral storage.
Now you possibly can choose a container within the activity definition, the supply EBS quantity, and supply a mount path the place the quantity shall be mounted within the activity.
You can too use $aws ecs register-task-definition --cli-input-json file://instance.json command line to register a activity definition so as to add an EBS quantity. The next snippet is a pattern, and activity definitions are saved in JSON format.
"household": "nginx"
...
"containerDefinitions": [
],
"volumes": [
"name": "/foo",
"configuredAtRuntime": true
]
2. Deploy and run your activity with EBS quantity
Now you possibly can run a activity by choosing your activity in your ECS cluster. Go to your ECS cluster and select Run new activity. Notice you could choose the compute choices, the launch kind, and your activity definition.
Notice: Whereas this instance goes by means of deploying a standalone activity with an connected EBS quantity, it’s also possible to configure a brand new or current ECS service to make use of EBS volumes with the specified configuration.
You’ve gotten a brand new Quantity part the place you possibly can configure the extra storage. The quantity identify, kind, and mount factors are those who you outlined in your activity definition. Select your EBS quantity sorts, sizes (GiB), IOPs, and the specified throughput.
You can not connect an current EBS quantity to an ECS activity. However if you wish to create a quantity from an current snapshot, you might have the choice to decide on your snapshot ID. If you wish to create a brand new quantity, then you possibly can go away this area empty. You possibly can select the file system kind, both ext3 or ext4 file techniques on Linux.
By default, when a activity is terminated, Amazon ECS deletes the connected quantity. Should you want the information within the EBS quantity to be retained after the duty exits, verify Delete on termination. Additionally, you might want to create an AWS Id and Entry Administration (IAM) function for quantity administration that accommodates the related permissions to permit Amazon ECS to make API calls in your behalf. For extra info on this coverage, see infrastructure function within the AWS documentation.
You can too configure encryption in your EBS volumes utilizing both Amazon managed keys and buyer managed keys. To study extra in regards to the choices, see our Amazon EBS encryption within the AWS documentation.
After configuring all activity settings, select Create to start out your activity.
three. Deploy and run your activity with EBS quantity
As soon as your activity has began, you possibly can see the quantity info on the duty definition particulars web page. Select a activity and choose the Volumes tab to seek out your created EBS quantity particulars.
Your staff can set up the event and operations of EBS volumes extra effectively. For instance, utility builders can configure the trail the place your utility expects storage to be accessible within the activity definition, and DevOps engineers can configure the precise EBS quantity attributes at runtime when the applying is deployed.
This enables DevOps engineers to deploy the identical activity definition to completely different environments with differing EBS quantity configurations, for instance, gp3 volumes within the improvement environments and io2 volumes in manufacturing.
Now accessible
Amazon ECS integration with Amazon EBS is offered in 9 AWS Areas: US East (Ohio), US East (N. Virginia), US West (Oregon), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Europe (Frankfurt), Europe (Eire), and Europe (Stockholm). You solely pay for what you employ, together with EBS volumes and snapshots. To study extra, see the Amazon EBS pricing web page and Amazon EBS volumes in ECS within the AWS documentation.
Give it a strive now and ship suggestions to our public roadmap, AWS re:Submit for Amazon ECS, or by means of your common AWS Help contacts.
