Install Loki with Docker or Docker Compose

You can use Grafana Cloud to avoid installing, maintaining, and scaling your own instance of Grafana Loki. Create a free account to get started, which includes free forever access to 10k metrics, 50GB logs, 50GB traces, 500VUh k6 testing & more.

You can install Loki and Promtail with Docker or Docker Compose if you are evaluating, testing, or developing Loki. For production, we recommend installing with Tanka or Helm.

Prerequisites

Install with Docker

Linux

Copy and paste the commands below into your command line.

bash 
wget https://raw.githubusercontent.com/grafana/loki/v2.3.0/cmd/loki/loki-local-config.yaml -O loki-config.yaml
docker run -v $(pwd):/mnt/config -p 3100:3100 grafana/loki:2.3.0 -config.file=/mnt/config/loki-config.yaml
wget https://raw.githubusercontent.com/grafana/loki/v2.3.0/clients/cmd/promtail/promtail-docker-config.yaml -O promtail-config.yaml
docker run -v $(pwd):/mnt/config -v /var/log:/var/log grafana/promtail:2.3.0 -config.file=/mnt/config/promtail-config.yaml

When finished, loki-config.yaml and promtail-config.yaml are downloaded in the directory you chose. Docker containers are running Loki and Promtail using those config files.

Navigate to http://localhost:3100/metrics to view the metrics and http://localhost:3100/ready for readiness.

As of v1.6.0, image is configured to run by default as user loki with UID 10001 and GID 10001. You can use a different user, specially if you are using bind mounts, by specifying the UID with a docker run command and using --user=UID with numeric UID suited to your needs.

Windows

Copy and paste the commands below into your terminal. Note that you will need to replace the <placeholders> in the commands with your local path.

bash 
cd "<local-path>"
wget https://raw.githubusercontent.com/grafana/loki/v2.3.0/cmd/loki/loki-local-config.yaml -O loki-config.yaml
docker run -v <local-path>:/mnt/config -p 3100:3100 grafana/loki:2.3.0 --config.file=/mnt/config/loki-config.yaml
wget https://raw.githubusercontent.com/grafana/loki/v2.3.0/clients/cmd/promtail/promtail-docker-config.yaml -O promtail-config.yaml
docker run -v <local-path>:/mnt/config -v /var/log:/var/log grafana/promtail:2.3.0 --config.file=/mnt/config/promtail-config.yaml

When finished, loki-config.yaml and promtail-config.yaml are downloaded in the directory you chose. Docker containers are running Loki and Promtail using those config files.

Navigate to http://localhost:3100/metrics to view the output.
