A small demonstration of a docker container that runs a R-script Keep in mind that this is a rather unsafe method to use your twitter keys you're much better of supplying them as arguments at build time.
- CD into the tweet folder
- modify the Rscript
- docker build to build the container
- docker run to run the container
cd tweet
# modify the R script (you'd be wise to change the keys or use
# a different way to add these keys to the image)
sudo docker build -t 'wikidatabot:v1' .
sudo docker run wikidatabot:v1
This container builds on the r-base container and installs all packages needed for the script to run. Unfortunately those are a lot of packages.
The script uses wikidataqueryr to query wikidata and retrieve a list of deaths. It selects one of those, glues the information from that death together and sends a tweet out with rtweet.
The init.R file is used on heroku.
-
Install the heroku commandline app.
-
Select the init.R and script.R file and commit them
-
run the following commands (the buildpack is external)
heroku --create
heroku buildpacks:set https://github.com/virtualstaticvoid/heroku-buildpack-r.git#heroku-16
heroku stack:set 'heroku-16'
git push heroku master
To make it run automatically every day you have to enable the scheduler. You need to add a creditcard.
- in the schedular set this command:
Rscript app/script.R
it now runs whenever you want to.
