Minimal Ansible role to manage grafana on CentOS 7.
Here's what it does:
- Install grafana package and dependencies and start service
- Install getdash.js
- Change default password
- Configure Influxdb datasource
TODO:
- Automatically verify that getdash.js works
- CentOS 7.x
- Ansible 2.x
- systemd
Grafana admin user. Used for authenticating to Grafana API.
grafana_admin_user: admin
Grafana admin default password, i.e. out-of-the-box password. This will be changed to grafana_admin_password.
grafana_admin_default_password: admin
Grafana admin password
grafana_admin_password: definitelynotadmin
File written when default password is changed
grafana_admin_password_is_changed_file: /usr/share/grafana/admin_password_is_changed
Directory where getdash.js repo (including its install script) is fetched
grafana_getdash_js_dest: /tmp/getdash_js
getdash.js upstream repo
grafana_getdash_js_repo: https://github.com/anryko/grafana-influx-dashboard.git
Name given to influxdb datasource. If a datasource with this name already exists, ansible will not attempt to re-add it.
grafana_influxdb_datasource_name: collectd (managed by ansible)
Influxdb user
grafana_influxdb_user: root
Influxdb password
grafana_influxdb_password: root
Grafana packages (including helper packages) to install
grafana_packages:
- grafana
- git # Needed for installing getdash.js
Port where Grafana server listens
grafana_port: 3000
Grafana yum repo information
grafana_repo: https://packagecloud.io/grafana/stable/el/$releasever/$basearch
grafana_repo_key: https://grafanarel.s3.amazonaws.com/RPM-GPG-KEY-grafana
Where Grafana helpers, such as scripted dashboards like getdash.js, are installed
grafana_root_dir: /usr/share/grafana
- hosts: servers
roles:
- ansible-grafana
Use molecule to test this role.
Because this role depends on systemd and might one day need SELinux (as related role ansible-influxdb does), only a Vagrant provider is configured at the moment.
