Upgrading Kapacitor

You can update the container via:

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

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• the prune gets rid of the outdated images.

Kapacitor version pinning

If you need to pin to a particular version:

1. Use your favourite text editor to create/edit an override file:

   ~/IOTstack/services/kapacitor/override.yml
   

2. Make the content look like this:

   kapacitor:
     image: kapacitor:1.5.9
   

   Note:
   • Be cautious about using the latest tag. At the time of writing, there was no linux/arm/v7 architecture support.

3. Apply the change:

   $ cd ~/IOTstack
   $ ./iotstack-menu.sh build 
   $ docker compose up -d kapacitor
