# Grafana Unified Alerting High Availability (HA) test setup
|
|
|
|
A set of docker compose services which together creates a Grafana HA test setup for unified alerting.
|
|
|
|
Included services
|
|
|
|
- Grafana
|
|
- Mysql - Grafana configuration database, exporter for metrics and session storage
|
|
- Prometheus - Monitoring of Grafana and used as data source
|
|
- Nginx - Reverse proxy for Grafana and Prometheus. Enables browsing Grafana/Prometheus UI using a hostname
|
|
|
|
## Prerequisites
|
|
|
|
### Build grafana docker container
|
|
|
|
Build a Grafana docker container from current branch and commit and tag it as grafana/grafana:dev.
|
|
|
|
```bash
|
|
$ cd <grafana repo>
|
|
$ make build-docker-full
|
|
```
|
|
|
|
### Virtual host names
|
|
|
|
#### Alternative 1 - Use dnsmasq
|
|
|
|
```bash
|
|
$ sudo apt-get install dnsmasq
|
|
$ echo 'address=/loc/127.0.0.1' | sudo tee /etc/dnsmasq.d/dnsmasq-loc.conf > /dev/null
|
|
$ sudo /etc/init.d/dnsmasq restart
|
|
$ ping whatever.loc
|
|
PING whatever.loc (127.0.0.1) 56(84) bytes of data.
|
|
64 bytes from localhost (127.0.0.1): icmp_seq=1 ttl=64 time=0.076 ms
|
|
--- whatever.loc ping statistics ---
|
|
1 packet transmitted, 1 received, 0% packet loss, time 1998ms
|
|
```
|
|
|
|
#### Alternative 2 - Manually update /etc/hosts
|
|
|
|
Update your `/etc/hosts` to be able to access Grafana and/or Prometheus UI using a hostname.
|
|
|
|
```bash
|
|
$ cat /etc/hosts
|
|
127.0.0.1 grafana.loc
|
|
127.0.0.1 prometheus.loc
|
|
```
|
|
|
|
## Start services
|
|
|
|
```bash
|
|
$ docker-compose up -d
|
|
```
