weewx-wdc-interceptor-docker

A simple Dockerfile to run weewx with the interceptor driver. The weewx-forecast extension is also installed along with weewx-wdc and weewx-cmon. There are branches available with weewx-DWD, weewx-mqtt, weewx-xcumulative and weewx-xaggs.

Usage

• Make changes to src/install-input.txt and src/skin.conf
• Build docker build . -t "weewx"
  • Default build args:
    • ARG WEEWX_VERSION="4.10.2"
    • ARG WDC_VERSION="v3.4.0"
• Run docker run -d --restart unless-stopped -p 9877:9877 --name weewx weewx
• Step into with docker exec -it weewx /bin/bash

Logs are in /var/log/syslog.

Working with named volumes

docker volume create weewx-db
docker volume create weewx-html
docker run -d --restart unless-stopped -p 9877:9877 --name weewx -v weewx-db:/home/weewx/archive -v weewx-html:/home/weewx/public_html weewx

Run nginx with weewx generated files: docker run -it --rm -d -p 8080:80 --name web -v weewx-html:/usr/share/nginx/html nginx

docker compose

A simple docker-compose.yml is included which starts a nginx server on localhost:8080.

docker compose up -d

install-input.txt

The template for the weewx install manager:

Value in txt	weewx Spec
Haselbachtal, Saxony, Germany	Station description
250, meter	Altitude
51.209	latitude
14.085	longitude

Here is the install output with the full dialogue:

Enter a brief description of the station, such as its location.  For example:
Santa's Workshop, North Pole
description [My Little Town, Oregon]:
Specify altitude, with units 'foot' or 'meter'.  For example:
35, foot
12, meter
altitude [700, foot]:
Specify latitude in decimal degrees, negative for south.
latitude [0.00]: Specify longitude in decimal degrees, negative for west.
longitude [0.00]:
You can register your station on weewx.com, where it will be included
in a map. You will need a unique URL to identify your station (such as a
website, or WeatherUnderground link).

Weather Data Center Skin or any other skin

Comment the lines 32 and 48 in the Dockerfile to deactivate the weewx-wdc skin. Or replace the download and file name with your own skin you want to install.

Admin scripts

backup.sh

Saves a backup of a named volume to the desired location. This can be run via cron to backup the SQLite DB. The backup file has a date suffix. Optionally, you can add a S3 Bucket and path as a third parameter to copy the backup to S3. The local backup gets removed in this case.

Usage: ./admin_scripts/backup.sh <VOLUME> <OUTPUT_DIRECTORY> <OPTIONAL S3 BUCKET AND PATH>

Example: "./admin_scripts/backup.sh weewx-db ./exports weewx-backup-bucket s3-bucket-name/path"

sync-s3.sh

Sync the generated HTML reports to a S3 bucket for web hosting. This needs the aws cli installed and configured. The volume path for a named volume should normally be something like /var/lib/docker/volumes/weewx-html/_data. Optionally you can add a third parameter with the Cloudfront Distribution ID to trigger an Invalidation for index.html.

For more information about AWS S3 static website hosting, see here https://docs.aws.amazon.com/AmazonS3/latest/userguide/website-hosting-custom-domain-walkthrough.html#root-domain-walkthrough-create-buckets

Usage: ./admin_scripts/sync-s3.sh <LOCAL FILE PATH> <S3 BUCKET AND PATH> <OPTIONAL CF DISTRIBUTION ID>

Example: "./admin_scripts/sync-s3.sh /var/lib/docker/volumes/weewx-html/_data weewx_web/"

I am using these two scripts as cronjobs on my PI installation:

# m h  dom mon dow   command
*/10 * * * * PATH=/usr/bin:/usr/local/bin && /home/pi/weewx-interceptor-docker/admin_scripts/sync-s3.sh /var/lib/docker/volumes/weewx-html/_data www.weewx-hbt.de/ XXXXXXXXXXXXXX
0 8 * * * PATH=/usr/bin:/usr/local/bin && /home/pi/weewx-interceptor-docker/admin_scripts/backup.sh weewx-db /tmp weewx-backup-sdb

Test

The Dockerfile is tested using dgoss:

dgoss run -p 9877:9877 weewx
