# Docker compose environment for VictoriaMetrics
|
|
|
|
Docker compose environment for VictoriaMetrics includes VictoriaMetrics components,
|
|
[Alertmanager](https://prometheus.io/docs/alerting/latest/alertmanager/)
|
|
and [Grafana](https://grafana.com/).
|
|
|
|
For starting the docker-compose environment ensure you have docker installed and running and access to the Internet.
|
|
**All commands should be executed from the root directory of [the repo](https://github.com/VictoriaMetrics/VictoriaMetrics).**
|
|
|
|
To spin-up environment for single server VictoriaMetrics run the following command:
|
|
```
|
|
make docker-single-up
|
|
```
|
|
|
|
To shut down the docker-compose environment for single server run the following command:
|
|
```
|
|
make docker-single-down
|
|
```
|
|
|
|
For cluster version the command will be the following:
|
|
```
|
|
make docker-cluster-up
|
|
```
|
|
|
|
To shut down the docker compose environment for cluster version run the following command:
|
|
```
|
|
make docker-cluster-down
|
|
```
|
|
|
|
## VictoriaMetrics single server
|
|
|
|
VictoriaMetrics will be accessible on the following ports:
|
|
|
|
* `--graphiteListenAddr=:2003`
|
|
* `--opentsdbListenAddr=:4242`
|
|
* `--httpListenAddr=:8428`
|
|
|
|
The communication scheme between components is the following:
|
|
* [vmagent](#vmagent) sends scraped metrics to `single server VictoriaMetrics`;
|
|
* [grafana](#grafana) is configured with datasource pointing to `single server VictoriaMetrics`;
|
|
* [vmalert](#vmalert) is configured to query `single server VictoriaMetrics` and send alerts state
|
|
and recording rules back to it;
|
|
* [alertmanager](#alertmanager) is configured to receive notifications from `vmalert`.
|
|
|
|
To access `vmalert` use link [http://localhost:8428/vmalert](http://localhost:8428/vmalert/).
|
|
|
|
To access [vmui](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#vmui)
|
|
use link [http://localhost:8428/vmui](http://localhost:8428/vmui).
|
|
|
|
## VictoriaMetrics cluster
|
|
|
|
VictoriaMetrics cluster environment consists of `vminsert`, `vmstorage` and `vmselect` components.
|
|
`vmselect` has exposed port `:8481`, `vminsert` has exposed port `:8480` and the rest of components
|
|
are available only inside the environment.
|
|
|
|
The communication scheme between components is the following:
|
|
* [vmagent](#vmagent) sends scraped metrics to `vminsert`;
|
|
* `vminsert` forwards data to `vmstorage`;
|
|
* `vmselect` is connected to `vmstorage` for querying data;
|
|
* [grafana](#grafana) is configured with datasource pointing to `vmselect`;
|
|
* [vmalert](#vmalert) is configured to query `vmselect` and send alerts state
|
|
and recording rules to `vminsert`;
|
|
* [alertmanager](#alertmanager) is configured to receive notifications from `vmalert`.
|
|
|
|
To access `vmalert` use link [http://localhost:8481/select/0/prometheus/vmalert](http://localhost:8481/select/0/prometheus/vmalert/).
|
|
|
|
To access [vmui](https://docs.victoriametrics.com/Single-server-VictoriaMetrics.html#vmui)
|
|
use link [http://localhost:8481/select/0/prometheus/vmui](http://localhost:8481/select/0/prometheus/vmui).
|
|
|
|
## vmagent
|
|
|
|
vmagent is used for scraping and pushing time series to VictoriaMetrics instance.
|
|
It accepts Prometheus-compatible configuration [prometheus.yml](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/deployment/docker/prometheus.yml)
|
|
with listed targets for scraping.
|
|
|
|
[Web interface link](http://localhost:8429/).
|
|
|
|
## vmalert
|
|
|
|
vmalert evaluates alerting rules [alerts.yml(https://github.com/VictoriaMetrics/VictoriaMetrics/blob/master/deployment/docker/alerts.yml)
|
|
to track VictoriaMetrics health state. It is connected with AlertManager for firing alerts,
|
|
and with VictoriaMetrics for executing queries and storing alert's state.
|
|
|
|
[Web interface link](http://localhost:8880/).
|
|
|
|
## alertmanager
|
|
|
|
AlertManager accepts notifications from `vmalert` and fires alerts.
|
|
All notifications are blackholed according to `alertmanager.yml` config.
|
|
|
|
[Web interface link](http://localhost:9093/).
