Elastic Container Service (ECS) (Docker)

Elastic Container Service; Docker => EC2;
Elastic Container Registry (ECR); handles ELB;
Run/manage containers across a cluster of EC2 instances.
DevGuide https://docs.aws.amazon.com/AmazonECS/latest/developerguide/docker-basics.html
CLI Ref https://docs.aws.amazon.com/cli/latest/reference/ecs/index.html

Workflow
CodeCommit (Git) => Docker CLI => ECR => ECS => EC2 Instance(s)

Two Launch Types
Fargate
Host a cluster on a serverless infra managed by ECS
Register Task Definition, and Fargate launches it.
- Bind Mounts
- Fargate Task Storage (10GB; ephemeral)
EC2
Host tasks on a cluster of EC2 instances
- Bind Mounts
- Docker Volumes (EBS:/var/lib/docker/volumes)
- Task Networking @ awsvpc Network Mode
  - So ECS tasks get same network properties as EC2 instances.

ECS/ECR (Elastic Container Registry; Repo)
ECS > Repositories > Create new repo
View Push Commands > (button; lists relevant aws & docker CLI commands)

# Login to AWS  
aws ecr get-login --no-include-email --region 'us-east-1'
# Returns login command w/ passord-key-string  ...
docker login -u AWS -p eyjwXYl4765elwrj8selrle77jq ... https://${AWS_ECR_REPO}.dkr.ecr.us-east-1.amazonaws.com
# ... copy/paste it back into terminal

Push to AWS

# Push Image to AWS
docker push "${AWS_ECR_REPO}.dkr.ecr.us-east-1.amazonaws.com/${NAME}:${TAG}"

Managed Kubernetes; service that handles scaling, upgrades and all of the management of the Kubernetes service and its clusters. https://aws.amazon.com/eks/
