Authenticate docker to Amazon ECR

aws ecr get-login-password --region us-east-1 [--profile prod|dev] | docker login --username AWS --password-stdin {$aws_account_id}.dkr.ecr.us-east-1.amazonaws.com

Use

To make use of this image, include the following in the task definition, changing the config-file-value as needed for your application

"firelensConfiguration": {
    "type": "fluentbit",
    "options": {
    "config-file-type": "file",
    "config-file-value": "/elastic.conf"
    }
},

Configs

• base.conf: configures baseline options
• elastic.conf: ships logs to a cloudwatch log stream and elastic cloud endpoint with env vars to config host, username, password and index.

Github Actions

There are two primary workflows here:

• dockerhub-publish.yml
• public-ecr-publish.yml

dockerhub-publish

Self-explanatory: publishes a container to our public Docker Hub repo based on a git tag.

There are limits on pulls, so we have migrated away from this as the primary endpoint.

public-ecr-publish

This workflow leverages AWS IAM roles and policies to publish a SHA-tagged and latest-tagged image to public repos within AWS ECR.

There is a build matrix for aws-region that will allow for pushing to other regions as we expand the AWS infrastructure to those regions.
