Upgrading a Validator

How to perform an upgrade on a validator

Helm Chart details:

Dynamic YAML Badge

validator: A Helm chart for deploying Chronicle Validator on Kubernetes

— Open in Artifact Hub

warning

ChartVersion 0.5.1: The tor-controller and its associated CRDs have been removed from the chart. The chart upgrade will automatically remove tor-related pods, services, and secrets that were previously managed by Helm. After upgrading, remove any remaining tor resources manually:

# Remove the onionservice resource (if present)
kubectl delete onionservice ghost -n $FEED_NAME --ignore-not-found

# If the tor-controller namespace was deployed, remove it
kubectl delete namespace tor-controller-system --ignore-not-found

# Remove all CRD's IF NOT USED BY OTHER APPS
kubectl delete -f https://raw.githubusercontent.com/chronicleprotocol/charts/validator-0.3.24/charts/validator/crds/tor-controller.yaml --ignore-not-found

Sample config:

global:
  logLevel: "warn"
  
ghost:
  ethConfig:
    ethFrom:
      existingSecret: '<somesecret>'
      key: "ethFrom"
    ethKeys:
      existingSecret: '<somesecret>'
      key: "ethKeyStore"
    ethPass:
      existingSecret: '<somesecret>'
      key: "ethPass"
  ethRpcUrl: "https://MY_L1_RPC_URL"
  rpcUrl: "https://MY_L1_RPC_URL"
  env:
    normal:
      CFG_LIBP2P_EXTERNAL_ADDR: '/ip4/1.2.3.4' # public/reachable ip address of node. If DNS hostname set to `/dns/my.validator.com`

vao:
  env:
    normal:
      CFG_LIBP2P_EXTERNAL_ADDR: '/ip4/1.2.3.4' # public/reachable ip address of node. If DNS hostname set to `/dns/my.validator.com`
Upgrading manually (helm upgrade)

Upgrading manually (helm upgrade)​

If you are upgrading from 0.3.x to 0.3.y, simply updating the chart version will suffice:

ssh <SERVER_IP>
su - <FEED_USERNAME>
export FEED_NAME=my-feed

Prepare values​

The values.yaml file is used to configure the validator. The file is generated by the install script, and should be updated to reflect the latest version of the feed chart.

With the latest version of the chart, there are a few changes that need to be made to the values.yaml / generated-values.yaml file:

Please structure your helm values like this:

global:
  logLevel: "warn"
ghost:
  ethConfig:
    ethFrom:
      existingSecret: '<somesecret>'
      key: "ethFrom"
    ethKeys:
      existingSecret: '<somesecret>'
      key: "ethKeyStore"
    ethPass:
      existingSecret: '<somesecret>'
      key: "ethPass"
  ethRpcUrl: "https://MY_L1_RPC_URL"
  rpcUrl: "https://MY_L1_RPC_URL"
  env:
    normal:
      CFG_LIBP2P_EXTERNAL_ADDR: '/ip4/1.2.3.4' # public/reachable ip address of node

vao:
  env:
    normal:
      CFG_LIBP2P_EXTERNAL_ADDR: '/ip4/1.2.3.4' # public/reachable ip address of node

danger

Please ensure your values yaml file is updated to reflect the latest requirements for the validator chart, with the correct values for ethConfig, ethRpcUrl and rpcUrl.

helm repo update
helm upgrade $FEED_NAME -n $FEED_NAME -f $HOME/$FEED_NAME/generated-values.yaml chronicle/validator --version 0.5.1
Upgrading using the helper script (upgrade.sh)

Upgrading using upgrade.sh​

To simplify the upgrade process, we have created a helper script that will upgrade your validator to the latest version.

This script will attempt to run helm upgrade <feedname> -n <feedname> chronicle/validator on your feed release, with any updated input variables.

caution

Please use the correct FEED_NAME, which should be the same as your helm release name, if deployed using the install.sh script previously

ssh <SERVER_IP>
su - <FEED_USERNAME>
export FEED_NAME=my-feed

Download the latest upgrade.sh​

Get the latest upgrade.sh script:

wget -N https://raw.githubusercontent.com/chronicleprotocol/scripts/main/feeds/k3s-install/upgrade.sh
chmod a+x upgrade.sh
./upgrade.sh
You can set the expected variables in the .env file, or export them as environment variables. If the script fails to find any of these values, it will prompt you for them when running the script.
tip

If kubectl/helm commands fail, please ensure you have $KUBECONFIG set correctly. Take a look here for more detail

Verify the helm release and version​

Verify the chart version has changed and matches what the latest feed version:

helm list -n $FEED_NAME
