Storing your docker images

Modified on Fri, 7 Apr, 2023 at 12:59 PM

There are many options available for storing docker images.

Storage in a public repository

For pipelines that are publicly available, dockerhub is the simplest option.

Dockerhub allows unlimited public repositories with a free account, where anyone can pull your images.

An existing image can be copied and renamed using your dockerhub user ID with:

docker tag image_name:0.0.1 userID/image_name:0.0.1

And then pushed to you dockerhub repository with:

docker push userID/image_name:0.0.1

Storage in a private repository

To store your docker images privately, we recommend amazon's elastic container registry (ECR).

With ECR, you have two options:

Option 1:

Store the image under your own aws account and setup the proper IAM policy to allow Basepair to pull images from your repository

Option 2:

Store the image in Basepair's ECR:
We will setup the proper IAM policy allowing you to push images to a private repository in our ECR.

- to do this, first contact a Basepair team member in order to share the necessary aws credentials

- once Basepair has created the repository, we will share the information needed for you to push images

*in the example code below, you will need to change values in brackets [] for your use:

Step 1: build the image using a tag that contains the repositoryUri we shared with you, the image name you want to use, and version ("v0.0.1")

cd /path/to/your/project # this is where the Dockerfile is present
docker build -f Dockerfile -t [repositoryUri]:[image_name]-[v0.0.1] .

check to make sure the image was created by listing existing images on your machine:

docker image ls

Step 2: get a temporary docker credential from ECR for use with docker login

aws ecr get-login-password \
--region [region]  \
| docker login --username AWS \
--password-stdin [aws_id].dkr.ecr.[region].amazonaws.com

Step 3: push the image to Basepair's ECR using the repositoryUri we shared with you

docker push [repositoryUri]:[image_name]-[v0.0.1]
