## Introduction

This chart bootstraps a [Argo Workflows](https://argoproj.github.io/workflows) deployment on a [Kubernetes](https://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.

Bitnami charts can be used with [Kubeapps](https://kubeapps.dev/) for deployment and management of Helm Charts in clusters.

## Prerequisites

- Kubernetes 1.23+
- Helm 3.8.0+
- PV provisioner support in the underlying infrastructure
- ReadWriteMany volumes for deployment scaling

## Installing the Chart

To install the chart with the release name `my-release`:

```console
helm install my-release oci://REGISTRY_NAME/REPOSITORY_NAME/argo-workflows
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The command deploys Argo Workflows on the Kubernetes cluster in the default configuration. The [Parameters](#parameters) section lists the parameters that can be configured during installation.

> **Tip**: List all releases using `helm list`

## Configuration and installation details

### Resource requests and limits

Bitnami charts allow setting resource requests and limits for all containers inside the chart deployment. These are inside the `resources` value (check parameter table). Setting requests is essential for production workloads and these should be adapted to your specific use case.

To make this process easier, the chart contains the `resourcesPreset` values, which automatically sets the `resources` section according to different presets. Check these presets in [the bitnami/common chart](https://github.com/bitnami/charts/blob/main/bitnami/common/templates/_resources.tpl#L15). However, in production workloads using `resourcesPreset` is discouraged as it may not fully adapt to your specific needs. Find more information on container resource management in the [official Kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/).

### [Rolling VS Immutable tags](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-understand-rolling-tags-containers-index.html)

It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.

Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

### Prometheus metrics

This chart can be integrated with Prometheus by setting `controller.metrics.enabled` to `true`. This will expose the Argo Workflows native Prometheus port in both the containers and services. The services will also have the necessary annotations to be automatically scraped by Prometheus.

#### Prometheus requirements

It is necessary to have a working installation of Prometheus or Prometheus Operator for the integration to work. Install the [Bitnami Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/prometheus) or the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) to easily have a working Prometheus in your cluster.

#### Integration with Prometheus Operator

The chart can deploy `ServiceMonitor` objects for integration with Prometheus Operator installations. To do so, set the value `controller.metrics.serviceMonitor.enabled=true`. Ensure that the Prometheus Operator `CustomResourceDefinitions` are installed in the cluster or it will fail with the following error:

```text
no matches for kind "ServiceMonitor" in version "monitoring.coreos.com/v1"
```

Install the [Bitnami Kube Prometheus helm chart](https://github.com/bitnami/charts/tree/main/bitnami/kube-prometheus) for having the necessary CRDs and the Prometheus Operator.

### Database support

You may want to have Argo Workflows controller connected to a database to store controller evidences. To achieve this, the chart can be deployed with the PostgreSQL or MySQL dependency (see next section to configure an external database instead of using the dependency). In order to configure the database, just change `postgresql.enabled=true` (default configuration) or `mysql.enabled=true`. The database will be configured automatically. Here is an example:

```console
postgresql.enabled=true
```

If your installation does not require to to store controller evidences, you can disable the controller persistence by setting `postgresql.enabled=false`, `mysql.enabled=false` and `externalDatabase.enabled=false`.

#### External database

You may want to have Argo Workflows controller connected to an external database to store controller evidences. To achieve this, the chart allows you to specify credentials for an external database (using either postgresql or mysql) with the [`controller.persistence.postgresql.enabled` or `controller.persistence.mysql.enabled` parameter](#parameters). You should also set `persistence.enabled` to `true`. Here is an example:

```console
externalDatabase.enabled=true
externalDatabase.type=postgresql
externalDatabase.host=<database_host>
externalDatabase.port=5432
externalDatabase.user=<database_user>
externalDatabase.password=<database_password>
externalDatabase.database=bitnami_workflows
```

### Backup and restore

To back up and restore Helm chart deployments on Kubernetes, you need to back up the persistent volumes from the source deployment and attach them to a new deployment using [Velero](https://velero.io/), a Kubernetes backup/restore tool. Find the instructions for using Velero in [this guide](https://techdocs.broadcom.com/us/en/vmware-tanzu/application-catalog/tanzu-application-catalog/services/tac-doc/apps-tutorials-backup-restore-deployments-velero-index.html).

### Ingress

This chart provides support for Ingress resources. If you have an ingress controller installed on your cluster, such as [nginx-ingress-controller](https://github.com/bitnami/charts/tree/main/bitnami/nginx-ingress-controller) or [contour](https://github.com/bitnami/charts/tree/main/bitnami/contour) you can utilize the ingress controller to serve your application. To enable Ingress integration, set `ingress.enabled` to `true`.

The most common scenario is to have one host name mapped to the deployment. In this case, the `ingress.hostname` property can be used to set the host name. The `ingress.tls` parameter can be used to add the TLS configuration for this host.

However, it is also possible to have more than one host. To facilitate this, the `ingress.extraHosts` parameter (if available) can be set with the host names specified as an array. The `ingress.extraTLS` parameter (if available) can also be used to add the TLS configuration for extra hosts.

> NOTE: For each host specified in the `ingress.extraHosts` parameter, it is necessary to set a name, path, and any annotations that the Ingress controller should know about. Not all annotations are supported by all Ingress controllers, but [this annotation reference document](https://github.com/kubernetes/ingress-nginx/blob/master/docs/user-guide/nginx-configuration/annotations.md) lists the annotations supported by many popular Ingress controllers.

Adding the TLS parameter (where available) will cause the chart to generate HTTPS URLs, and the  application will be available on port 443. The actual TLS secrets do not have to be generated by this chart. However, if TLS is enabled, the Ingress record will not work until the TLS secret exists.

[Learn more about Ingress controllers](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/).

### Securing traffic using TLS

This chart facilitates the creation of TLS secrets for use with the Ingress controller (although this is not mandatory). There are several common use cases:

- Generate certificate secrets based on chart parameters.
- Enable externally generated certificates.
- Manage application certificates via an external service (like [cert-manager](https://github.com/jetstack/cert-manager/)).
- Create self-signed certificates within the chart (if supported).

In the first two cases, a certificate and a key are needed. Files are expected in `.pem` format.

Here is an example of a certificate file:

> NOTE: There may be more than one certificate if there is a certificate chain.

```text
-----BEGIN CERTIFICATE-----
MIID6TCCAtGgAwIBAgIJAIaCwivkeB5EMA0GCSqGSIb3DQEBCwUAMFYxCzAJBgNV
...
jScrvkiBO65F46KioCL9h5tDvomdU1aqpI/CBzhvZn1c0ZTf87tGQR8NK7v7
-----END CERTIFICATE-----
```

Here is an example of a certificate key:

```text
-----BEGIN RSA PRIVATE KEY-----
MIIEogIBAAKCAQEAvLYcyu8f3skuRyUgeeNpeDvYBCDcgq+LsWap6zbX5f8oLqp4
...
wrj2wDbCDCFmfqnSJ+dKI3vFLlEz44sAV8jX/kd4Y6ZTQhlLbYc=
-----END RSA PRIVATE KEY-----
```

- If using Helm to manage the certificates based on the parameters, copy these values into the `certificate` and `key` values for a given `*.ingress.secrets` entry.
- If managing TLS secrets separately, it is necessary to create a TLS secret with name `INGRESS_HOSTNAME-tls` (where INGRESS_HOSTNAME is a placeholder to be replaced with the hostname you set using the `*.ingress.hostname` parameter).
- If your cluster has a [cert-manager](https://github.com/jetstack/cert-manager) add-on to automate the management and issuance of TLS certificates, add to `*.ingress.annotations` the [corresponding ones](https://cert-manager.io/docs/usage/ingress/#supported-annotations) for cert-manager.
- If using self-signed certificates created by Helm, set both `*.ingress.tls` and `*.ingress.selfSigned` to `true`.

### Additional environment variables

In case you want to add extra environment variables (useful for advanced operations like custom init scripts), you can use the `extraEnvVars` property.

```yaml
argo-workflows:
  extraEnvVars:
    - name: LOG_LEVEL
      value: error
```

Alternatively, you can use a ConfigMap or a Secret with the environment variables. To do so, use the `extraEnvVarsCM` or the `extraEnvVarsSecret` values.

### Sidecars

If additional containers are needed in the same pod as argo-workflows (such as additional metrics or logging exporters), they can be defined using the `sidecars` parameter.

```yaml
sidecars:
- name: your-image-name
  image: your-image
  imagePullPolicy: Always
  ports:
  - name: portname
    containerPort: 1234
```

If these sidecars export extra ports, extra port definitions can be added using the `service.extraPorts` parameter (where available), as shown in the example below:

```yaml
service:
  extraPorts:
  - name: extraPort
    port: 11311
    targetPort: 11311
```

> NOTE: This Helm chart already includes sidecar containers for the Prometheus exporters (where applicable). These can be activated by adding the `--enable-metrics=true` parameter at deployment time. The `sidecars` parameter should therefore only be used for any extra sidecar containers.

If additional init containers are needed in the same pod, they can be defined using the `initContainers` parameter. Here is an example:

```yaml
initContainers:
  - name: your-image-name
    image: your-image
    imagePullPolicy: Always
    ports:
      - name: portname
        containerPort: 1234
```

Learn more about [sidecar containers](https://kubernetes.io/docs/concepts/workloads/pods/) and [init containers](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/).

### Pod affinity

This chart allows you to set your custom affinity using the `affinity` parameter. Find more information about Pod affinity in the [kubernetes documentation](https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity).

As an alternative, use one of the preset configurations for pod affinity, pod anti-affinity, and node affinity available at the [bitnami/common](https://github.com/bitnami/charts/tree/main/bitnami/common#affinities) chart. To do so, set the `podAffinityPreset`, `podAntiAffinityPreset`, or `nodeAffinityPreset` parameters.

See <https://github.com/bitnami/readme-generator-for-helm> to create the table

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install my-release \
  --set argo-workflowsUsername=admin \
  --set argo-workflowsPassword=password \
  --set mysql.auth.rootPassword=secretpassword \
    oci://REGISTRY_NAME/REPOSITORY_NAME/argo-workflows
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.

The above command sets the Argo Workflows administrator account username and password to `admin` and `password` respectively. Additionally, it sets the MySQL `root` user password to `secretpassword`.

> NOTE: Once this chart is deployed, it is not possible to change the application's access credentials, such as usernames or passwords, using Helm. To change these application credentials after deployment, delete any persistent volumes (PVs) used by the chart and re-deploy it, or use the application's built-in administrative tools if available.

Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,

```console
helm install my-release -f values.yaml oci://REGISTRY_NAME/REPOSITORY_NAME/argo-workflows
```

> Note: You need to substitute the placeholders `REGISTRY_NAME` and `REPOSITORY_NAME` with a reference to your Helm chart registry and repository. For example, in the case of Bitnami, you need to use `REGISTRY_NAME=registry-1.docker.io` and `REPOSITORY_NAME=bitnamicharts`.
> **Tip**: You can use the default [values.yaml](https://github.com/bitnami/charts/tree/main/bitnami/argo-workflows/values.yaml)

## Upgrading

### To 11.1.0

This version introduces image verification for security purposes. To disable it, set `global.security.allowInsecureImages` to `true`. More details at [GitHub issue](https://github.com/bitnami/charts/issues/30850).

### To 11.0.0

This major bump updates the MySQL subchart to version 12.0.0. This subchart updates the StatefulSet objects `serviceName` to use a headless service, as the current non-headless service attached to it was not providing DNS entries. This will cause an upgrade issue because it changes "immutable fields". To workaround it, delete the StatefulSet objects as follows (replace the RELEASE_NAME placeholder):

```shell
kubectl delete sts RELEASE_NAME-mysql --cascade=false
```

Then execute `helm upgrade` as usual.

### To 10.0.0

This major updates the PostgreSQL subchart to its newest major, 16.0.0, which uses PostgreSQL 17.x.  Follow the [official instructions](https://www.postgresql.org/docs/17/upgrading.html) to upgrade to 17.x.

### To 9.0.0

This major updates the MySQL subchart to its newest major, 11.0.0. For more information on this subchart's major, please refer to [Mysql upgrade notes](https://github.com/bitnami/charts/blob/main/bitnami/mysql/README.md#user-content-to-1100).

### To 8.0.0

This major bump changes the following security defaults:

- `resourcesPreset` is changed from `none` to the minimum size working in our test suites (NOTE: `resourcesPreset` is not meant for production usage, but `resources` adapted to your use case).
- `global.compatibility.openshift.adaptSecurityContext` is changed from `disabled` to `auto`.

This could potentially break any customization or init scripts used in your deployment. If this is the case, change the default values to the previous ones.

### To 7.0.0

This major release bumps the PostgreSQL chart version to [14.x.x](https://github.com/bitnami/charts/pull/22750); no major issues are expected during the upgrade.

### To 6.0.0

This major updates the PostgreSQL subchart to its newest major, 13.0.0. [Here](https://github.com/bitnami/charts/tree/master/bitnami/postgresql#to-1300) you can find more information about the changes introduced in that version.

### To 5.0.0

This major moved the parameters under `server.auth.sso` to `server.auth.sso.config`.

### To 4.0.0

This major updates the PostgreSQL subchart to its newest major, 12.0.0. [Here](https://github.com/bitnami/charts/tree/master/bitnami/postgresql#to-1200) you can find more information about the changes introduced in that version.

### To 2.0.0

This major release updates the MySQL subchart to its newest major *9.x.x*, which contain several changes in the supported values (check the [upgrade notes](https://github.com/bitnami/charts/tree/main/bitnami/mysql#to-900) to obtain more information).

### To 1.0.0

This major release updates the PostgreSQL subchart to its newest major *11.x.x*, which contain several changes in the supported values (check the [upgrade notes](https://github.com/bitnami/charts/tree/main/bitnami/postgresql#to-1100) to obtain more information).

#### Upgrading Instructions

To upgrade to *1.0.0* from *0.x*, it should be done reusing the PVC(s) used to hold the data on your previous release. To do so, follow the instructions below (the following example assumes that the release name is *argo-workflows* and the release namespace *default*):

1. Obtain the credentials and the names of the PVCs used to hold the data on your current release:

```console
        export POSTGRESQL_PASSWORD=$(kubectl get secret --namespace default argo-workflows-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)
        export POSTGRESQL_PVC=$(kubectl get pvc -l app.kubernetes.io/instance=argo-workflows,app.kubernetes.io/name=postgresql,role=primary -o jsonpath="{.items[0].metadata.name}")
```

1. Delete the PostgreSQL statefulset (notice the option *--cascade=false*) and secret:

```console
        kubectl delete statefulsets.apps --cascade=false argo-workflows-postgresql
        kubectl delete secret argo-workflows-postgresql --namespace default
```

1. Upgrade your release using the same PostgreSQL version:

```console
        CURRENT_PG_VERSION=$(kubectl exec argo-workflows-postgresql-0 -- bash -c 'echo $BITNAMI_IMAGE_VERSION')
        helm upgrade argo-workflows bitnami/argo-workflows \
          --set postgresql.image.tag=$CURRENT_PG_VERSION \
          --set postgresql.auth.password=$POSTGRESQL_PASSWORD \
          --set postgresql.persistence.existingClaim=$POSTGRESQL_PVC
```

1. Delete the existing PostgreSQL pods and the new statefulset will create a new one:

```console
        kubectl delete pod argo-workflows-postgresql-0
```
