Docker Container for Meetup Reports

This container handles the gathering of Ansible Meetup data, the generating/sending of the email report, and the updater for Discourse. Each task can be run independently (caveat that get_events.R has run at least once to make a dataset).

Setup

This container requires two mount points:

• a config dir mounted to /srv/docker-config/meetup for the OAuth token, meetup list, and email config
• a pins dir mounted to /srv/docker-pins/meetup for storing/reading data

Example dir layout

Inside the container it should look like this:

/srv/docker-config
└── meetup
    ├── email.yml
    ├── httr-oauth.meetupr
    └── meetups.yml
/srv/docker-pins
└── meetup

httR OAuth file

Getting the OAuth token is a bit fiddly. In short, look at the MeetupR docs and generate one. Ask me if you get stuck. Save the file in the config mount-point as above

Email config file

I'm assuming a Gmail account in the code, just provide a file that looks like the example in this repo.

Meetup config file

Yaml file of white- and black-listed meetups. The code actually downloads this file directly from GitHub, so just open PRs against it.

Build the container

podman build --tag meetupr .

Run the container

All the tasks are designed for a single execution

Example single run of get_events.R

This is the default action and builds a pin of the groups and events

podman run --rm -ti -v /srv/docker-config/meetup/:/srv/docker-config/meetup/ -v /srv/docker-pins/meetup:/srv/docker-pins/meetup meetupr:latest Rscript get_events.R

Example single run of send_email.R

This renders meetup_report.Rmd and emails it

podman run --rm -ti -v /srv/docker-config/meetup/:/srv/docker-config/meetup/ -v /srv/docker-pins/meetup:/srv/docker-pins/meetup meetupr:latest Rscript send_email.R

Example single run of the Discourse updater

Uses the API of Discourse to create events - requires a Discourse block in the config file, see the example.

podman run --rm -ti -v /srv/docker-config/meetup/:/srv/docker-config/meetup/ -v /srv/docker-pins/meetup:/srv/docker-pins/meetup meetupr:latest Rscript update_discourse.R

Interactive testing

You can run an R shell in the container - this is the container default:

podman run --rm -ti -v /srv/docker-config/meetup/:/srv/docker-config/meetup/ -v /srv/docker-pins/meetup:/srv/docker-pins/meetup meetupr:latest
