Amazon Elastic Container Registry (ECR)
How to store container images in Amazon ECR
The AWS container registry is a container registry flavor provided with the ZenML aws
integration and uses Amazon ECR to store container images.
When to use it
You should use the AWS container registry if:
-
one or more components of your stack need to pull or push container images.
-
you have access to AWS ECR. If you’re not using AWS, take a look at the other container registry flavors.
How to deploy it
The ECR registry is automatically activated once you create an AWS account. However, you’ll need to create a Repository
in order to push container images to it:
-
Go to the ECR website.
-
Make sure the correct region is selected on the top right.
-
Click on
Create repository
. -
Create a private repository. The name of the repository depends on the [orchestrator](../orchestrators/orchestrators.md or step operator you’re using in your stack.
URI format
The AWS container registry URI should have the following format:
To figure our the URI for your registry:
-
Go to the AWS console and click on your user account in the top right to see the
Account ID
. -
Go here and choose the region in which you would like to store your container images. Make sure to choose a nearby region for faster access.
-
Once you have both these values, fill in the values in this template
<ACCOUNT_ID>.dkr.ecr.<REGION>.amazonaws.com
to get your container registry URI.
How to use it
To use the AWS container registry, we need:
- The ZenML
aws
integration installed. If you haven’t done so, run
-
Docker installed and running.
-
The AWS CLI installed and authenticated.
-
The registry URI. Check out the previous section on the URI format and how to get the URI for your registry.
We can then register the container registry and use it in our active stack:
Additionally, we’ll need to log in to the container registry so Docker can pull and push images:
