# VictoriaLogs Quick Start
It is recommended to read [README](https://docs.victoriametrics.com/VictoriaLogs/)
and [Key Concepts](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html)
before you start working with VictoriaLogs.
## How to install and run VictoriaLogs
There are the following options exist:
- [To run Docker image](#docker-image)
- [To build VictoriaLogs from source code](#building-from-source-code)
### Docker image
You can run VictoriaLogs in a Docker container. It is the easiest way to start using VictoriaLogs.
Here is the command to run VictoriaLogs in a Docker container:
```bash
docker run --rm -it -p 9428:9428 -v ./victoria-logs-data:/victoria-logs-data \
docker.io/victoriametrics/victoria-logs:heads-public-single-node-0-ga638f5e2b
```
### Building from source code
Follow the following steps in order to build VictoriaLogs from source code:
- Checkout VictoriaLogs source code. It is located in the VictoriaMetrics repository:
```bash
git clone https://github.com/VictoriaMetrics/VictoriaMetrics
cd VictoriaMetrics
```
- Build VictoriaLogs. The build command requires [Go 1.20](https://golang.org/doc/install).
```bash
make victoria-logs
```
- Run the built binary:
```bash
bin/victoria-logs
```
VictoriaLogs is ready for [data ingestion](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/)
and [querying](https://docs.victoriametrics.com/VictoriaLogs/querying/) at the TCP port `9428` now!
It has no any external dependencies, so it may run in various environments without additional setup and configuration.
VictoriaLogs automatically adapts to the available CPU and RAM resources. It also automatically setups and creates
the needed indexes during [data ingestion](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/).
It is possible to change the TCP port via `-httpListenAddr` command-line flag. For example, the following command
starts VictoriaLogs, which accepts incoming requests at port `9200` (aka ElasticSearch HTTP API port):
```bash
/path/to/victoria-logs -httpListenAddr=:9200
```
VictoriaLogs stores the ingested data to the `victoria-logs-data` directory by default. The directory can be changed
via `-storageDataPath` command-line flag. See [these docs](https://docs.victoriametrics.com/VictoriaLogs/#storage) for details.
By default VictoriaLogs stores [log entries](https://docs.victoriametrics.com/VictoriaLogs/keyConcepts.html) with timestamps
in the time range `[now-7d, now]`, while dropping logs outside the given time range.
E.g. it uses the retention of 7 days. Read [these docs](https://docs.victoriametrics.com/VictoriaLogs/#retention) on how to control the retention
for the [ingested](https://docs.victoriametrics.com/VictoriaLogs/data-ingestion/) logs.
It is recommended setting up monitoring of VictoriaLogs according to [these docs](https://docs.victoriametrics.com/VictoriaLogs/#monitoring).
