Victoria Logs Single version - high-performance, cost-effective and scalable logs storage
Prerequisites #
Install the follow packages:
git
,kubectl
,helm
,helm-docs
. See this tutorial.PV support on underlying infrastructure.
Chart Details #
This chart will do the following:
- Rollout Victoria Logs Single.
- (optional) Rollout vector to collect logs from pods.
Chart allows to configure logs collection from Kubernetes pods to VictoriaLogs. In order to do that you need to enable vector:
vector:
enabled: true
By default, vector will forward logs to VictoriaLogs installation deployed by this chart.
How to install #
Access a Kubernetes cluster.
Setup chart repository (can be omitted for OCI repositories) #
Add a chart helm repository with follow commands:
helm repo add vm https://victoriametrics.github.io/helm-charts/
helm repo update
List versions of vm/victoria-logs-single
chart available to installation:
helm search repo vm/victoria-logs-single -l
Install victoria-logs-single
chart
#
Export default values of victoria-logs-single
chart to file values.yaml
:
For HTTPS repository
helm show values vm/victoria-logs-single > values.yaml
For OCI repository
helm show values oci://ghcr.io/victoriametrics/helm-charts/victoria-logs-single > values.yaml
Change the values according to the need of the environment in values.yaml
file.
Test the installation with command:
For HTTPS repository
helm install vls vm/victoria-logs-single -f values.yaml -n NAMESPACE --debug --dry-run
For OCI repository
helm install vls oci://ghcr.io/victoriametrics/helm-charts/victoria-logs-single -f values.yaml -n NAMESPACE --debug --dry-run
Install chart with command:
For HTTPS repository
helm install vls vm/victoria-logs-single -f values.yaml -n NAMESPACE
For OCI repository
helm install vls oci://ghcr.io/victoriametrics/helm-charts/victoria-logs-single -f values.yaml -n NAMESPACE
Get the pods lists by running this commands:
kubectl get pods -A | grep 'vls'
Get the application by running this command:
helm list -f vls -n NAMESPACE
See the history of versions of vls
application with command.
helm history vls -n NAMESPACE
How to uninstall #
Remove application with command.
helm uninstall vls -n NAMESPACE
Documentation of Helm Chart #
Install helm-docs
following the instructions on this tutorial.
Generate docs with helm-docs
command.
cd charts/victoria-logs-single
helm-docs
The markdown generation is entirely go template driven. The tool parses metadata from charts and generates a number of sub-templates that can be referenced in a template file (by default README.md.gotmpl
). If no template file is provided, the tool has a default internal template that will generate a reasonably formatted README.
Parameters #
The following tables lists the configurable parameters of the chart and their default values.
Change the values according to the need of the environment in victoria-logs-single/values.yaml
