Basics

ECR is the Elastic Container Registry. It’s for storing something like Docker images.

To use an image that’s stored in ECR, select a repository, click “View Push Commands” to get the login command, then simply do something like:

docker run -it 212785478310.dkr.ecr.us-west-2.amazonaws.com/botland/overseer:latest

Remember, this requires the environment variables to be set, which you can typically do by using —env-file .env.development

Here are the steps that I went through for all of this from the beginning:

I already had an IAM, so I didn’t need to do anything there.
Install the newest AWS CLI (reference)
- Install pip
- $ pip install awscli —upgrade —user
- Test to make sure it’s installed: $ aws —version
Go to ECR in the AWS console (i.e. the UI online)
ECR → Repositories → Get started
For “Repository name”, keep in mind that each semantic image is going to go into its own repository, so I came up with “botland/verdaccio”, “botland/overseer”, etc.
Click “next step”
Follow the instructions on the page, making sure to copy the ”$” in the first command.

AWS console → ECS → Repositories → Your repository → View Push Commands
Follow the steps in there
Typically, after doing this in production, you’d want to also update any related task definitions (if you didn’t just refer to the ":latest" one, in which case just update services as follows) and then any services based on those definitions.
