# Intro
- Background
- Docker refresher
- Coreos refresher

# UP architecture diagram

# The Cluster
- fleetctl list-units
- look at some logs
- look at some logs
- ssh to a node. ps -ef, etc.
---
# End to End publication
- show healthcheck endpoints
- mention NOT externally accessible at the moment
- force ingest content uuid (wordpress?) via curl and see it from the api-policy-component (demo owlim persist)
- force ingest content uuid (wordpress?) via curl and see it from the document-store-api (demo mongo persist)
- publish
```bash
curl -i -H "Content-Type : application/json" -H "Host: ingester-content" -H "X-Request-Id: bodor001" -X POST -d '{ "contentUri" : "http://whatever/content/f1332fc0-0f54-11e5-897e-00144feabdc0", "destination" : "methode-article-transformer", "relativeUrl" : "content/f1332fc0-0f54-11e5-897e-00144feabdc0"}' localhost:8080/ingest/
```
- verify:
```bash
curl -H "Host: document-store-api" -H "Content-Type : application/json" -X GET localhost:8080/content/f1332fc0-0f54-11e5-897e-00144feabdc0

# Operating a service in the cluster
- fleetctl stop/destroy/start xxx.service
- show a request not working.
---
# Logging & Monitoring
- show logging in cluster splunk
- show logging on server
- show accessing docker container
- monitoring prometheus http://ip-172-31-20-111.eu-west-1.compute.internal:9090
```bash
#Vulcan CPU usage
sum(rate(container_cpu_usage_seconds_total{name="vulcan"}[2m]) * 100) by (name, instance)

# Security
- access key storage - ansible encryption
- access through proxy - talk about
```bash
ssh -Nn -D 2323 core@$FLEETCTL_TUNNEL
```

# Adding a new service to the cluster “manually”
- create a simple Dockerfile
- create a dockerhub build trigger????
- build and push to Dockerhub
- creating a service file
- deploy with fleetctl
---
# Automating things
- Deployer
* adding service.yaml for deployment tool or fleetctl?
* demo new service deploying cluster
- Auto created metrics
* see metrics for the new service in graphite + logs?
---
# Taking down nodes and observing recovery?
kill mongo master?
---
# Building Docker images for current applications?
- jenkins jobs http://ftapp09665-lviw-uk-p.osb.ft.com:8080/
- images on dockerhub?
- talk about versioning
