* Sync a few files from fission-all to fission-core chart * Change values in fission-all chart We keep the following components by default disabled now, which were enabled by default earlier. 1. nats - Fission Nats integration 2. influxdb - Influxdb and logger component 3. prometheus - Prometheus disabled by default 4. canaryDeployment - Disabled by default This change reduces the need for a fission-core chart and we can configure values of fission-all so that it can provide the behaviour of fission-all as well as fission-core. * Remove fission-core chart * Add README in the fission-all chart * Rename clusterrolebinding fission-crd to fission-cr-admin * Add icon and sources in helm chart Signed-off-by: Sanket Sudake <sanketsudake@gmail.com>

# fission-all
|
|
|
|
[Fission](https://fission.io/) is a framework for serverless functions on Kubernetes.
|
|
|
|
## Prerequisites
|
|
|
|
- Kubernetes 1.19+
|
|
- Helm 3+
|
|
|
|
## Get Repo Info
|
|
|
|
```console
|
|
helm repo add fission-charts https://fission.github.io/fission-charts
|
|
helm repo update
|
|
```
|
|
|
|
_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._
|
|
|
|
## Install Chart
|
|
|
|
Replace `{{version}}` with [the latest Fission version](https://github.com/fission/fission/releases/latest).
|
|
|
|
|
|
```console
|
|
# Helm
|
|
$ export FISSION_NAMESPACE="fission"
|
|
$ kubectl create namespace $FISSION_NAMESPACE
|
|
$ kubectl create -k "github.com/fission/fission/crds/v1?ref={{version}}"
|
|
$ helm install [RELEASE_NAME] fission-charts/fission-all --namespace fission
|
|
```
|
|
|
|
_See [configuration](#configuration) below._
|
|
|
|
_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
|
|
|
|
## Dependencies
|
|
|
|
By default this chart installs additional, dependent charts:
|
|
|
|
- [prometheus-community/prometheus](https://github.com/prometheus-community/helm-charts/tree/main/charts/prometheus)
|
|
|
|
To disable dependencies during installation, see [multiple releases](#multiple-releases) below.
|
|
|
|
_See [helm dependency](https://helm.sh/docs/helm/helm_dependency/) for command documentation._
|
|
|
|
## Uninstall Chart
|
|
|
|
```console
|
|
# Helm
|
|
$ helm uninstall [RELEASE_NAME]
|
|
```
|
|
|
|
This removes all the Kubernetes components associated with the chart and deletes the release.
|
|
|
|
_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
|
|
|
|
CRDs are not removed by this chart and should be manually cleaned up:
|
|
|
|
`{{version}}` references the version you used during the installation of chart.
|
|
|
|
```console
|
|
kubectl delete -k "github.com/fission/fission/crds/v1?ref={{version}}"
|
|
```
|
|
|
|
OR
|
|
|
|
You can list all Fission CRDs and clean them up with `kubectl delete crd` command.
|
|
|
|
```console
|
|
kubectl get crds| grep ".fission.io"
|
|
```
|
|
|
|
## Upgrading Chart
|
|
|
|
CRDs created by this chart are not updated by default and should be manually updated.
|
|
|
|
`{{version}}` references the version you are upgrading to 
|
|
|
|
```console
|
|
kubectl replace -k "github.com/fission/fission/crds/v1?ref={{version}}"
|
|
```
|
|
|
|
```console
|
|
# Helm
|
|
$ helm upgrade [RELEASE_NAME] fission-charts/fission-all
|
|
```
|
|
|
|
_See [configuration](#configuration) below._
|
|
|
|
_See [helm upgrade](https://helm.sh/docs/helm/helm_upgrade/) for command documentation._
|
|
|
|
### Upgrading an existing Release to a new major version
|
|
|
|
A major chart version change (like v1.2.3 -> v2.0.0) indicates that there is an incompatible breaking change needing manual actions.
|
|
|
|
## Configuration
|
|
|
|
See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments:
|
|
|
|
```console
|
|
helm show values fission-charts/fission-all
|
|
```
|
|
|
|
You may also `helm show values` on this chart's [dependencies](#dependencies) for additional options.
|
|
|
|
### Multiple releases
|
|
|
|
The same chart can be used to run multiple Fission instances in the same cluster if required. To disable a dependency during installation, set `prometheus.enabled` to `false`.
