Setup

Manual setup

You can deploy your instance of el_monitorro by:
  1. Set postgres db url (DATABASE_URL) and telegram bot token (TELEGRAM_BOT_TOKEN) to .env file in the root directory. For example:
DATABASE_URL=postgres://admin:pass@localhost/el_monitorro
TELEGRAM_BOT_TOKEN=MYTOKEN
  1. Setup database by running:
diesel database setup
You'll need diesel-cli for this
  1. Start the bot
  • Start the command bot
RUST_LOG=info RUST_BACKTRACE=1 cargo run --bin el_monitorro
  • Start the sync binary
RUST_LOG=info RUST_BACKTRACE=1 cargo run --bin sync
  • Start the delivery binary
RUST_LOG=info RUST_BACKTRACE=1 cargo run --bin deliver
  • If you don't want to store all feed items that were synced and feeds without any subscriptions, start the cleaner binary
RUST_LOG=info RUST_BACKTRACE=1 cargo run --bin cleaner

Running all services from a single binary

Set ALL_BINARIES to run all binaries (clean, commands, deliver, sync) in the same binary:
ALL_BINARIES=true

Using docker image

The image is published on docker hub under ayratbadykov/el_monitorro. It accepts additional env variables:
  • SETUP_DB - if this variable is not empty, diesel database setup is run. It creates DB and runs migrations.
  • RUN_MIGRATION - if this variable is not empty, diesel migration run is run. It just runs migrations.
  • BOT_BINARY - depending on this variable, docker container will run one of four binaries. Possible values are commands, sync, deliver, cleaner. To run all services in the main binary, set:
RUN_MIGRATION=true
BOT_BINARY=commands
ALL_BINARIES=true
Run the docker container:
docker run --env-file ./.env --network host -t ayratbadykov/el_monitorro:latest
Notes:
  • -network host is used so the docker container can access a host network if you're running Postgres on the same machine
You can check out an example of docker-compose file in the root directory of the project.

Creating a docker image from the latest master branch

Run the following command in the el_monitorro directory to build the image from the master branch:
docker build ./ -t ayratbadykov/el_monitorro:latest
