Loghouse is a ready to use log management solution for Kubernetes. Efficiently store big amounts of your logs (in ClickHouse database), process them using a simple query language and monitor them online through web UI. Easy and quick to deploy in an already functioning Kubernetes cluster.
Installation
To install loghouse, you need to use Helm. Minimal kubernetes cluster version is >=1.9. Also, it is considered that cert-manager is already installed in your cluster.
The whole process is as simple as these two steps:
- Add loghouse charts:
# helm repo add loghouse https://flant.github.io/loghouse/charts/ - Install a chart.
2.1. Easy way:
# helm fetch loghouse/loghouse --untar
# vim loghouse/values.yaml
# helm install --namespace loghouse -n loghouse loghouse
Note: use --timeout 1200 flag in case slow image pulling.
2.2. Using specific parameters (check variables in chart’s values.yaml — not documented yet):
# helm install -n loghouse loghouse/loghouse --set 'param=value' ...
Web UI (loghouse-dashboard) will be reachable via address specified in values.yaml config as loghouse_host. You’ll be prompted by basic authorization generated via htpasswd and configured in auth parameter of your values.yaml.
To clean old logs in cron, you can use a script in this issue.
