![]() ![]() To create SOCI indexes, you can use the soci CLI provided by the soci-snapshotter project. Create SOCI indexes manually – This approach provides more flexibility on in how the SOCI indexes are created, including for existing container images in Amazon ECR repositories.Then, another AWS Lambda function generates and pushes SOCI indexes to repositories in the Amazon ECR registry. This AWS CloudFormation stack deploys an Amazon EventBridge rule to identify Amazon ECR action events and invoke an AWS Lambda function to match the defined filter. Use AWS SOCI Index Builder – AWS SOCI Index Builder is a serverless solution for indexing container images in the AWS Cloud.There are two ways to create SOCI indexes for container images. This also means that AWS Fargate will still continue to run container images that don’t have SOCI indexes. When you use Amazon ECS with AWS Fargate to run your SOCI-indexed containerized images, AWS Fargate automatically detects if a SOCI index for the image exists and starts the container without waiting for the entire image to be pulled. At release, AWS Fargate support for SOCI works with Amazon Elastic Container Registry (Amazon ECR). The index is then stored in the registry alongside the container image. This means that your container images don’t need to be converted to use SOCI, therefore not breaking secure hash algorithm (SHA)-based security, such as container image signing. This allows you to deploy and scale out applications more quickly and reduce the rollout time for application updates.Ī SOCI index is generated and stored separately from the container images. Your applications no longer need to wait to complete pulling and unpacking a container image before your applications start running. This index is a key enabler to launching containers faster, providing the capability to extract an individual file from a container image without having to download the entire image. SOCI works by creating an index (SOCI index) of the files within an existing container image. Here’s a quick look to show how AWS Fargate support for SOCI works: At launch, this new capability is available for Amazon Elastic Container Service (Amazon ECS) applications running on AWS Fargate. Today, I’m excited to share that AWS Fargate now supports Seekable OCI (SOCI), which helps applications deploy and scale out faster by enabling containers to start without waiting to download the entire container image. As part of that effort, we open sourced SOCI Snapshotter, a snapshotter plugin that enables lazy loading with SOCI in containerd. Last year, we introduced Seekable OCI (SOCI), a technology open sourced by Amazon Web Services (AWS) that enables container runtimes to implement lazy loading the container image to start applications faster without modifying the container images. This approach downloads data from the container registry in parallel with the application startup, such as stargz-snapshotter, a project that aims to improve the overall container start time. One solution to this problem is lazy loading (also known as asynchronous loading) container images. This may introduce a non-trivial latency, as the entire image must be downloaded and unpacked before the applications can be started. Starting and scaling out containerized applications requires downloading container images from a remote container registry. This issue can have a negative impact on the customer experience, for example when a website needs to scale out to serve additional traffic.Ī research paper shows that container image downloads account for 76 percent of container startup time, but on average only 6.4 percent of the data is needed for the container to start doing useful work. One of the main issues with scaling containerized applications is the long startup time, especially during scale up when newer instances need to be added. ![]() ![]() While developing with containers is becoming an increasingly popular way for deploying and scaling applications, there are still areas where improvements can be made. ![]()
