vector

Vector

Vector is a high-performance, end-to-end observability data pipeline that puts you in control of your observability data. Collect, transform, and route all your logs, metrics, and traces to any vendors you want today and any other vendors you may want tomorrow. Vector enables dramatic cost reduction, novel data enrichment, and data security where you need it, not where is most convenient for your vendors.

How to use Vector Helm repository

You need to add this repository to your Helm repositories:

helm repo add vector https://helm.vector.dev
helm repo update

Requirements

Kubernetes: >=1.15.0-0

Quick start

By default, Vector runs as a StatefulSet in the "Aggregator" role. It can alternatively run as a Deployment for the "Stateless-Aggregator" role or a DaemonSet for the "Agent" role.

Installing the Vector chart

To install the chart with the release name <RELEASE_NAME> run:

helm install --name <RELEASE_NAME> \
  vector/vector

Upgrading

From original charts

• Migrate from the vector-agent chart
• Migrate from the vector-aggregator chart

Uninstalling the chart

To uninstall/delete the <RELEASE_NAME> deployment:

helm delete <RELEASE_NAME>

The command removes all the Kubernetes components associated with the chart and deletes the release.

Configuration

1. Using our default-values.yaml configuration file as a reference, create your own values.yaml.
2. Upgrade the Vector chart with your new values.yaml file:

helm upgrade -f values.yaml <RELEASE_NAME> vector/vector

Vector recommends that your values.yaml only contain values that need to be overridden, as it allows a smoother experience when upgrading chart versions.

See the configuration options section to discover all possibilities offered by the Vector chart.

Running on control plane nodes

Depending on your Kubernetes distribution, you may need to configure tolerations to run Vector on nodes acting as the control plane.

For example to run Vector on Openshift control plane nodes you can set:

tolerations:
  - effect: NoSchedule
    key: node-role.kubernetes.io/master
    operator: Exists
  - effect: NoSchedule
    key: node-role.kubernetes.io/infra
    operator: Exists

Or for RKE control plane nodes set:

tolerations:
  - effect: NoSchedule
    key: node-role.kubernetes.io/controlplane
    operator: Exists
  - effect: NoExecute
    key: node-role.kubernetes.io/etcd
    operator: Exists

Using template syntax in customConfig

As Vector's template syntax shares the same syntax as Helm templates, explicit handling is required if you are using Vector's template syntax in the customConfig option. To avoid Helm templating configuration intended for Vector you can supply configuration like so:

customConfig:
  #...
  sinks:
    loki:
      #...
      labels:
        foo: bar
        host: |-
          {{ print "{{ host }}" }}
        source: |-
          {{ print "{{ source_type }}" }}

All configuration options

The following table lists the configurable parameters of the Vector chart and their default values. Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,

helm install --name <RELEASE_NAME> \
  --set role=Agent \
  vector/vector
