Run script

python3 iServer.py localhost 8086 xxxx
where xxxx is the iServer's address you want to access

Build Docker container

• Install Docker
  Follow the first two sections of the excellent guide Getting Started with Docker if you are not familiar with Docker.

• Running InfluxDB in Docker
  Pull official influxdb image and list images locally installed on your computer. (Note please use version 1.8)

docker pull influxdb:1.8
docker image ls

You should see influxdb listed.

Now create a container from this image and run it:

docker run -d -p 8086:8086 -v influxdb:/var/lib/influxdb --name influxdb influxdb:1.8

You can stop and restart the container by doing:

docker container stop influxdb
docker container start influxdb

• Grafana
  Use official grafana image by doing:

docker pull grafana/grafana
docker run -p 3000:3000 -v grafana:/var/lib/grafana grafana/grafana

Port 3000 on the local host is redirected to port 3000 in the grafana container.
Log in to grafana by pointing your web browser to http://localhost:3000. Use the default user and password: admin / admin .

• Build iserver container
  clone this repo and build container:

git clone https://github.com/bdongmd/iServer-docker.git
cd iServer-docker
docker build . -t iserver

• Network setting
  The sensor scrip will be running in a container based on the sensor image. So in this container, localhost points to the container itself. Since this container does not run the InfluxDB server, so the script won't find http://localhost:8086 .

Docker containers can see each other only if they share the same network. So the solution is to connect the containers to the same network.
So let's create a network:

docker network create mynet

Add the influxdb container to this network:

docker network connect mynet influxdb

• Run container At last, run iserver container on the same network:

docker run --network mynet iserver

If you would like to run the container over a different iServer than the default one used here, run:

docker run --network mynet iserver python -u influxdb 8086 ip_addr

where ip_addr is the ip adress of the iServer you would like to access.
