Step 3

This is the solution for the challenge in step 2.

1. Run docker ps -q | xargs docker stop to stop all running containers
2. Change directory to services/serializer
3. Run docker build -t serializer .
4. Run influxdb docker run -d -p 8083:8083 -p 8086:8086 --expose 8090 --expose 8099 tutum/influxdb
5. Run sh ./runContainer.sh
6. Run the curl command below, it will return null, run it a couple of times to add some dummy data
7. Open the influxdb console with docker exec -ti <containerID> /opt/influxdb/influx
8. Execute use temperature; select * from temperature; in the influx console to see the data

Data add curl:

curl -X POST -d "{\"role\": \"serialize\", \"cmd\": \"write\", \"sensorId\": \"1\", \"temperature\": 32}"

Challenge

Running multiple containers individually is error prone, your challenge is to use docker-compose. In this step you will create a docker compose yml file to launch all our containers with a single command.

A skeleton docker-compose.yml is provided for you, you just need to fill in the settings for the various containers.

Hint: You can see a completed docker-compose.yaml here
