## Compose sample application
|
||||||
|
|
||||||
|
### Python/Flask application
|
||||||
|
|
||||||
|
```
|
||||||
|
+--------------------+ +------------------+
|
||||||
|
| | | |
|
||||||
|
| Python Flask | timestamps | Redis |
|
||||||
|
| Application |------------->| |
|
||||||
|
| | | |
|
||||||
|
+--------------------+ +------------------+
|
||||||
|
```
|
||||||
|
|
||||||
|
### Things you'll need to do.
|
||||||
|
|
||||||
|
There are a number of places you'll need to fill in information. You can find them with:
|
||||||
|
|
||||||
|
```
|
||||||
|
grep -r '<<<' ./*
|
||||||
|
./docker-compose.yml: x-aws-pull_credentials: <<<your arn for your secret you can get with docker ecs secret list>>>
|
||||||
|
./docker-compose.yml: image: <<<yourhubname>>>/timestamper
|
||||||
|
## Walk through
|
||||||
|
```
|
||||||
|
|
||||||
|
### Setup pull credentials for private Docker Hub repositories
|
||||||
|
|
||||||
|
You should use a Personal Access Token (PAT) vs your default password. If you have 2FA enabled on your Hub account you will have to create a PAT. You can read more about managing access tokens here: https://docs.docker.com/docker-hub/access-tokens/
|
||||||
|
|
||||||
|
```
|
||||||
|
docker ecs secret create -d MyKey -u myhubusername -p myhubpat
|
||||||
|
```
|
||||||
|
|
||||||
|
### Create an AWS Docker context and list available contexts
|
||||||
|
|
||||||
|
```
|
||||||
|
docker ecs setup
|
||||||
|
Enter context name: aws
|
||||||
|
✔ sandbox.devtools.developer
|
||||||
|
Enter cluster name:
|
||||||
|
Enter region: us-west-2
|
||||||
|
✗ Enter credentials:
|
||||||
|
|
||||||
|
docker context ls
|
||||||
|
NAME DESCRIPTION DOCKER ENDPOINT KUBERNETES ENDPOINT ORCHESTRATOR
|
||||||
|
aws
|
||||||
|
default * Current DOCKER_HOST based configuration unix:///var/run/docker.sock swarm
|
||||||
|
```
|
||||||
|
|
||||||
|
### Test locally
|
||||||
|
|
||||||
|
```
|
||||||
|
docker context use default
|
||||||
|
docker-compose up
|
||||||
|
open http://localhost:5000
|
||||||
|
```
|
||||||
|
|
||||||
|
### Push images to hub for ecs (ecs cannot see your local image cache)
|
||||||
|
|
||||||
|
```
|
||||||
|
docker-compose push
|
||||||
|
```
|
||||||
|
|
||||||
|
### Switch to ECS context and launch the app
|
||||||
|
|
||||||
|
```
|
||||||
|
docker context use aws
|
||||||
|
docker ecs compose up
|
||||||
|
```
|
||||||
|
|
||||||
|
### Check out the CLI
|
||||||
|
|
||||||
|
```
|
||||||
|
docker ecs compose ps
|
||||||
|
docker ecs compose logs
|
||||||
|
```
|
||||||
|
|
||||||
|
### Check out the aws console
|
||||||
|
|
||||||
|
- cloud formation
|
||||||
|
- cloud watch
|
||||||
|
- security groups
|
||||||
|
- Load balancers (ELB for this example / ALB if your app only uses 80/443)
|
||||||
|
|
||||||
|
### Checkout cloudformation
|
||||||
|
|
||||||
|
```
|
||||||
|
docker ecs compose convert
|
||||||
|
```
|
||||||
|
|
||||||
|
### Stop the meters
|
||||||
|
|
||||||
|
```
|
||||||
|
docker ecs compose down
|
||||||
|
|
||||||
|
```
|
||||||
|
|
||||||
|
## Using Amazon ECR instead of Docker Hub
|
||||||
|
|
||||||
|
[Makefile](Makefile) has an example setup for creating an ECR repository and pushing to it. You'll need to have the AWS CLI installed and your AWS credentials available.
|
||||||
|
|
||||||
|
```
|
||||||
|
make create-ecr
|
||||||
|
REGISTRY_ID=<from the create above> make build-image
|
||||||
|
REGISTRY_ID=<from the create above> make push-image-ecr
|
||||||
|
```
|
||||||
|
|
||||||
|
If you want to use this often, you'll likely want to replace `PUT_ECR_REGISTRY_ID_HERE` with the value from above.
