prometheus-manager

Centralized configuration management and storage for prometheus-configurator.

how-to

Setup local development environment

Export the path to the devel config (from the root of this repository):

$ export PROMETHEUS_MANAGER_CONFIG_PATH=$PWD/config.example.yaml

Start the mariadb instance using docker-compose:

$ docker compose up -d

Wait a few seconds, and then we need to create the non-admin user:

$ mariadb -h 127.0.0.1 --user=root --password=root -e "grant all privileges on prometheusconfig.* to 'prometheusconfig'@'%' identified by 'prometheusconfig';"

Now we can run the migrations to populate the database:

$ python3 scripts/pm-migrate
INFO  [alembic.runtime.migration] Context impl MySQLImpl.
INFO  [alembic.runtime.migration] Will assume non-transactional DDL.
INFO  [alembic.runtime.migration] Running upgrade  -> 639f4dd7f8c4, create projects table
...

Run the service:

$ flask run
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
WARNING: This is a development server. Do not use it in a production deployment. Use a production WSGI server instead.
 * Running on http://127.0.0.1:5000

Create new database migrations
