AWS ECR anonymous proxy

Based on official nginx alpine.

The container will renew the aws token every 6 hours.

Variables required:

AWS_KEY
AWS_SECRET
REGION

Note: For AWS instances if the region is not declared it will be auto discovered from IAM as long as the instance supports that. pull request, commit. If the credentials are mounted as a volume or secret the REGION needs to be present in the config file.

Other variables:

RENEW_TOKEN - default 6h

or mount ~/.aws/config file with all the required configurations. (more details below)

Docker run:

Without ssl

This will require either to add insecure registry URL or a load balancer with valid ssl certificates. Check https://docs.docker.com/registry/insecure/ for more details.

docker run -e AWS_SECRET='YOUR_AWS_SECRET' \
-e AWS_KEY='YOUR_AWS_KEY' \
-e REGION='YOUR_AWS_REGION' \
-d catalinpan/aws-ecr-proxy

With your own certificate

docker run -e AWS_SECRET='YOUR_AWS_SECRET' \
-e AWS_KEY='YOUR_AWS_KEY' \
-e REGION='YOUR_AWS_REGION' \
-v `pwd`/YOUR_CERTIFICATE.key:/etc/nginx/ssl/default.key:ro \
-v `pwd`/YOUR_CERTIFICATE.crt:/etc/nginx/ssl/default.crt:ro \
-d catalinpan/aws-ecr-proxy

With a valid AWS CLI configuration file

The configuration should look like below example.

cat ~/.aws/config

[default]
# region example eu-west-1
region = REGION     
aws_access_key_id = YOUR_AWS_KEY
aws_secret_access_key = YOUR_AWS_SECRET

docker run -v ~/.aws:/root/.aws:ro
-v `pwd`/YOUR_CERTIFICATE.key:/etc/nginx/ssl/default.key:ro \
-v `pwd`/YOUR_CERTIFICATE.crt:/etc/nginx/ssl/default.crt:ro \
-d catalinpan/aws-ecr-proxy

SSL

The certificates included are just to get nginx started. Generate your own certificate, get valid ssl certificates or use the container behind a load balancer with valid SSL certificates.

Self signed certificates

openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout default.key -out default.crt

Kubernetes example

The configuration provided will require valid ssl certificates or to be behind a load balancer with valid ssl. The configuration can be changed to get aws_config and ssl certificates as secrets.

Kubernetes deployment contains also a health check.
