Server Installation

There are several approaches to setup Siren Server

  1. Using the CLI
  2. Using the Docker
  3. Using the Helm Chart

General pre-requisites​

  • PostgreSQL (version 13 or above)
  • Monitoring Providers
    • Ex: CortexMetrics

Using the CLI​

Pre-requisites for CLI​

To run the Siren server use command:

$ siren server start -c <path-to-config>

Use the Docker​

To run the Siren server using Docker, you need to have Docker installed on your system. You can find the installation instructions here.

You can choose to set the configuration using environment variables or a config file. The environment variables will override the config file.

Using environment variables​

All the configs can be passed as environment variables using underscore _ as the delimiter between nested keys. See the following examples

See configuration reference for the list of all the configuration keys.

.env
DB_DRIVER=postgres
DB_URL=postgres://postgres:@localhost:5432/siren_development?sslmode=disable
SERVICE_PORT=8080
SERVICE_ENCRYPTION_KEY=<32 characters encryption key>

Run the following command to start the server

$ docker run -d \
    --restart=always \
    -p 8080:8080 \
    --env-file .env \
    --name siren-server \
    gotocompany/siren:<version> \
    server start

Using config file​

config.yaml
db:
  driver: postgres
  url: postgres://postgres:@localhost:5432/siren_integration?sslmode=disable
service:
  port: 8080
  encryption_key: <32 characters encryption key>

Run the following command to start the server

$ docker run -d \
    --restart=always \
    -p 8080:8080 \
    -v $(pwd)/config.yaml:/config.yaml \
    --name siren-server \
    gotocompany/siren:<version> \
    server start -c /config.yaml

Use the Helm chart​

Pre-requisites for Helm chart​

Siren can be installed in Kubernetes using the Helm chart from https://github.com/goto/charts.

Ensure that the following requirements are met:

  • Kubernetes 1.14+
  • Helm version 3.x is installed

Add gotocompany Helm repository​

Add gotocompany chart repository to Helm:

helm repo add gotocompany https://goto.github.io/charts/

You can update the chart repository by running:

helm repo update

Setup helm values​

The following table lists the configurable parameters of the Siren chart and their default values.

See full helm values guide here.

values.yaml
app:

  ## Value to fully override guardian.name template
  nameOverride: ""
  ## Value to fully override guardian.fullname template
  fullnameOverride: ""

  image:
    repository: gotocompany/siren
    pullPolicy: Always
    tag: latest
  container:
    args:
      - server
      - start
    livenessProbe:
      httpGet:
        path: /ping
        port: tcp
    readinessProbe:
      httpGet:
        path: /ping
        port: tcp

  migration:
    enabled: true
    args:
      - server
      - migrate

  service:
    annotations:
      projectcontour.io/upstream-protocol.h2c: tcp

  ingress:
    enabled: true
    annotations:
      kubernetes.io/ingress.class: contour
    hosts:
      - host: siren.example.com
        paths:
          - path: /
            pathType: ImplementationSpecific
            backend:
              service:
                # name: backend_01
                port:
                  number: 8080

  config:
    LOG_LEVEL: info
    SERVICE_PORT: 8080

  secretConfig:
    ENCRYPTION_SECRET_KEY:
    NOTIFIER_ACCESS_TOKEN:
    DB_URL: postgres://siren:<password>@localhost:5432/siren_integration?sslmode=disable

And install it with the helm command line along with the values file:

$ helm install my-release -f values.yaml gotocompany/siren
