Ian Wienand 70c1fb2dff grafana: update docs and make an import script
Update the docs to reflect not having grafyaml in the container.

Also move the import into a separate helper script, which can be
manually run on the host if the container needs to be restarted
out-of-band for some reason.

Grafana
#######
Grafana is an open source, feature rich metrics dashboard and graph editor for
Graphite, InfluxDB & OpenTSDB. OpenStack runs Graphite which stores all the
metrics related to Nodepool and Zuul (to name a few).

Overview
========
Apache is configured as a reverse proxy to Grafana running in a
container, listening on port 3000.
Updating dashboards
===================
Changes to config-files in ``project-config`` will trigger the
``infra-prod-run-grafana`` job to refresh the dashboards. If the
container is restarted manually, you can run
``/usr/local/bin/update-grafana-dashboards`` on
``grafana.opendev.org`` to reload directly.
Local Development
=================
To develop dashboards, you can run the Grafana container.
Firstly, get setup:
.. code-block:: shell-session
$ cd <work dir>
$ mkdir secrets
$ echo "password" > secrets/admin_password
$ echo "admin" > secrets/admin_user
$ echo "key" > secrets/secret_key
$ git clone https://opendev.org/openstack/project-config
Then run the container with the following options:
.. code-block:: shell-session
$ cd <work dir>
$ sudo podman run \
-p 3000:3000 \
-v ./secrets:/etc/grafana/secrets \
-e GF_AUTH_ANONYMOUS_ENABLED=true \
-e GF_USERS_ALLOW_SIGN_UP=false \
-e GF_SECURITY_ADMIN_PASSWORD__FILE=/etc/grafana/secrets/admin_password \
-e GF_SECURITY_ADMIN_USER__FILE=/etc/grafana/secrets/admin_user \
-e GF_SECURITY_SECRET_KEY__FILE=/etc/grafana/secrets/secret_key \
docker.io/grafana/grafana-oss
At this point, Grafana will be running and listening on port 3000.
You can log into as ``admin`` with ``password`` (or using your secrets
above).
This is unconfigured and does not yet talk to the OpenDev Graphite
instance. The dashboard definitions are kept in
``project-config/grafana``. You need to run the ``grafyaml`` tool to
load them.
.. code-block:: shell-session
$ echo 'GRAFANA_URL=http://admin:password@localhost:3000/' > grafyaml.env
$ docker run --rm -t --network=host \
--env-file ./grafyaml.env \
-v ./project-config/grafana:/grafana:ro \
opendevorg/grafyaml
To work on dashboards, update the ``yaml`` files in ``project-config``
and re-run the grafyaml import as above, then reload them in the
Grafana UI.
Alternatively, you can use the Grafana editor to make the dashboards,
and then under "Dashboard Settings" (gear icon) select "JSON Model"
and commit that (it seems you have to cut-and-paste, there isn't
currently a way to export the JSON as such). The raw JSON can be
proposed as an addition to ``project-config``.
