Upgrade guidance 1.13 onwards

Note: Fission upgrades cause a downtime as of now, however we try to minimize it. Please upvote the issue#1856 so we can priortize fixing it.

Upgrade to the latest Fission version


kubectl replace -k "github.com/fission/fission/crds/v1?ref=v1.21.0"

Please make sure you have the latest CLI installed. Refer to Fission CLI Installation

Update the helm repo and upgrade by mentioning the namespace Fission is installed in :


export FISSION_NAMESPACE="fission"
helm repo update
helm upgrade --namespace $FISSION_NAMESPACE fission fission-charts/fission-all

With 1.15.x release, following changes are made:

fission-core chart is removed
fission-all chart is made similar fission-core chart
In the fission-all chart, the following components are disabled which were enabled by default earlier. If you want to enable them, please use --set flag.
- nats - Set nats.enabled=true to enable Fission Nats integration
- influxdb - Set influxdb.enabled=true to enable Fission InfluxDB and logger component
- prometheus - Set prometheus.enabled=true to install Prometheus with Fission
- canaryDeployment - Set canaryDeployment.enabled=true to enable Canary Deployment

Fission-all chart is now exactly similar to fission-core chart and can be used to migrate from fission-core.

If you are upgrading from the fission-core chart, you can use the following command to migrate with required changes.


helm upgrade [RELEASE_NAME] fission-charts/fission-all --namespace fission
