Kapacitor integration¶

If you selected Kapacitor in the menu and want Chronograf to be able to interact with it, you need to edit docker-compose.yml to un-comment the lines which are commented-out in the following:

chronograf:
  …
  environment:
  …
  # - KAPACITOR_URL=http://kapacitor:9092
  depends_on:
  …
  # - kapacitor

If the Chronograf container is already running when you make this change, run:

$ cd ~IOTstack
$ docker-compose up -d chronograf

Upgrading Chronograf¶

You can update the container via:

$ cd ~/IOTstack
$ docker-compose pull
$ docker-compose up -d
$ docker system prune

In words:

docker-compose pull downloads any newer images;
docker-compose up -d causes any newly-downloaded images to be instantiated as containers (replacing the old containers); and
the prune gets rid of the outdated images.

Chronograf version pinning¶

If you need to pin to a particular version:

Use your favourite text editor to open docker-compose.yml.
Find the line:
```
image: chronograf:latest
```
Replace latest with the version you wish to pin to. For example, to pin to version 1.9.0:
```
image: chronograf:1.9.0
```

Save the file and tell docker-compose to bring up the container:

$ cd ~/IOTstack
$ docker-compose up -d chronograf
$ docker system prune
