weewx-docker 🌩🐳

This docker container can be used to quickly get a WeeWX instance up and running.

This container has the following WeeWX extensions installed:

• interceptor
• mqtt

Running

Running with Docker

Pull felddy/weewx from the Docker repository:

docker pull felddy/weewx

Run

The easiest way to start the container is to create a docker-compose.yml similar to the following. If you use a serial port to connect to your weather station, make sure the container has permissions to access the port. The uid/gid can be set using the environment variables below.

Modify any paths or devices as needed:

---
version: "3.8"

volumes:
  data:

services:
  weewx:
    image: felddy/weewx
    init: true
    restart: "yes"
    volumes:
      - type: bind
        source: ./data
        target: /data
    environment:
      - TIMEZONE=US/Eastern
      - WEEWX_UID=weewx
      - WEEWX_GID=dialout
    devices:
      - "/dev/ttyUSB0:/dev/ttyUSB0"

1. Create a directory on the host to store the configuration and database files:

   mkdir data

2. If this is the first time running weewx, use the following command to start the container and generate a configuration file:

   docker-compose run weewx

3. The configuration file will be created in the data directory. You should edit this file to match the setup of your weather station.

4. When you are satisfied with configuration the container can be started in the background with:

   docker-compose up -d

Upgrading

1. Stop the running container:

   docker-compose down

2. Pull the new images from the Docker hub:

   docker-compose pull

3. Update your configuration file (a backup will be created):

   docker-compose run weewx --upgrade

4. Read through the new configuration and verify. It is helpful to diff the new config with the backup. Check the WeeWX Upgrade Guide for instructions for specific versions.

5. Start the container up with the new image version:

   docker-compose up -d

Volumes

Mount point	Purpose
/data	configuration file and sqlite database storage

Environment Variables

Variable	Purpose	Default
TIMEZONE	Container TZ database name	UTC
WEEWX_UID	uid the daemon will be run under	weewx
WEEWX_GID	gid the deamon will be run under	weewx

Building from source

Build the image locally using this git repository as the build context:

docker build \
  --tag felddy/weewx:4.8.0 \
  https://github.com/felddy/weewx-docker.git#develop

Cross-platform builds

To create images that are compatible with other platforms you can use the buildx feature of Docker:

1. Copy the project to your machine using the Clone button above or the command line:

   git clone https://github.com/felddy/weewx-docker.git
   cd weewx-docker

2. Create the Dockerfile-x file with buildx platform support:

   ./buildx-dockerfile.sh

3. Build the image using buildx:

   docker buildx build \
     --file Dockerfile-x \
     --platform linux/amd64 \
     --output type=docker \
     --tag felddy/weewx:4.8.0 .

Debugging

There are a few helper arguments that can be used to diagnose container issues in your environment.

Purpose	Command
Generate the default configuration	docker-compose run weewx
Upgrade a previous configuration	docker-compose run weewx --upgrade
Generate a test (simulator) configuration	docker-compose run weewx --gen-test-config
Drop into a shell in the container	docker-compose run weewx --shell
