Values Reference

This page covers every top-level parameter group in the Bifrost Helm chart’s values.yaml, how to supply values via --set vs -f, and where to find ready-made example files.

The full values schema is available at https://getbifrost.ai/schema. All values.yaml fields map directly to config.json fields generated by the chart.

Supplying Values

One-liner with `--set`

Good for a single field or quick experiments:

helm install bifrost bifrost/bifrost \
  --set image.tag=v1.4.11 \
  --set replicaCount=3 \
  --set bifrost.client.initialPoolSize=500

Values file with `-f`

Recommended for anything beyond a couple of fields:

# Create your values file
cat > my-values.yaml <<'EOF'
image:
  tag: "v1.4.11"

replicaCount: 2

bifrost:
  encryptionKey: "your-32-byte-encryption-key-here"
  client:
    initialPoolSize: 500
    enableLogging: true
EOF

# Install
helm install bifrost bifrost/bifrost -f my-values.yaml

# Upgrade later
helm upgrade bifrost bifrost/bifrost -f my-values.yaml

# Upgrade and reuse all previously set values, overriding only one field
helm upgrade bifrost bifrost/bifrost \
  --reuse-values \
  --set replicaCount=5

Multiple values files

Later files override earlier ones - useful for a base + environment-specific overlay:

helm install bifrost bifrost/bifrost \
  -f base-values.yaml \
  -f production-overrides.yaml

Key Parameters Reference

Image

Parameter	Description	Default
`image.repository`	Container image repository	`docker.io/maximhq/bifrost`

Replicas & Autoscaling

Parameter	Description	Default
`replicaCount`	Static replica count (ignored when HPA is enabled)	`1`

Parameter	Description	Default
`ingress.enabled`	Enable ingress	`false`
`ingress.className`	Ingress class (e.g. `nginx`, `traefik`)	`""`

Three ways to inject env vars:

# Inline key/value pairs
env:
  - name: HTTP_PROXY
    value: "http://proxy.corp.example.com:3128"

# Map syntax (appended after env)
extraEnv:
  NO_PROXY: "169.254.169.254,10.0.0.0/8"

Node Affinity & Scheduling

Deploy to specific nodes and spread replicas across hosts:

nodeSelector:
  node-type: ai-workload

affinity:
  podAntiAffinity:
    requiredDuringSchedulingIgnoredDuringExecution:
      - labelSelector:
          matchLabels:
            app.kubernetes.io/name: bifrost
        topologyKey: kubernetes.io/hostname

tolerations:
  - key: "gpu"
    operator: "Equal"
    value: "true"
    effect: "NoSchedule"

Deployment & Pod Annotations

Useful for tooling like Keel for automatic image updates or Datadog APM injection:

deploymentAnnotations:
  keel.sh/policy: force
  keel.sh/trigger: poll

podAnnotations:
  ad.datadoghq.com/bifrost.logs: '[{"source":"bifrost","service":"bifrost"}]'

Common Patterns

Ready-made values files for the most common deployment scenarios. Each pattern builds on the quickstart.

Development
Multi-Provider
External Database
AI Workloads
Kubernetes Secrets Only

Simple setup for local testing. SQLite, single replica, no autoscaling.
