Overview
========
Apache is configured as a reverse proxy and there is a MySQL database
backend.
Apache is configured as a reverse proxy to Grafana running in a
container, listening on port 3000.
Sysadmin
========
Local Development
=================
After bringing up a Grafana node with puppet, log in and configure Grafana by
hand:
To develop dashboards, you can run the OpenDev Grafana container.
Firstly, get setup:
#. Log in as the admin user.
.. code-block:: shell-session
#. Under 'Data Sources', add a new entry with following:
$ cd <work dir>
$ mkdir secrets
$ echo "password" > secrets/admin_password
$ echo "admin" > secrets/admin_user
$ echo "key" > secrets/secret_key
- name: OpenStack
- type: Graphite
- default: checked
- url: http://graphite.opendev.org
- access: direct
$ 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 \
-v ./project-config:/opt/project-config \
-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/opendevorg/grafana
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``. To load them ``exec`` the
``update-grafana`` script in the container (i.e. ``podman exec
<running-container> update-grafana``). That will run ``grafyaml`` and
load in the updated dashboards (note it relies on things being mapped
as above). To work on dashboards, update the ``yaml`` files in
``project-config`` and re-run ``update-grafana``, 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).
