# Application catalog

All applications are enabled by default. Disable optional applications in [charts/services/values.yaml](charts/services/values.yaml); core cluster services remain enabled.

This page is the operational reference. It lists the included applications and only expands the ones that need credentials, external accounts, first-run configuration, or a non-default recovery procedure.

## High availability

Redis, PostgreSQL, Authentik, CrowdSec, and Homer Operator run with three replicas by default. On limited hardware, set `highAvailability: false` in your inventory values to run one replica of each instead. This reduces resource use and fault tolerance.

```yaml
# In your inventory chartValuesOverrides or values.yaml
highAvailability: false  # Set to false to use 1 replica instead of 3
```

- **Open WebUI:** Requires PostgreSQL. It connects to llama.cpp automatically when enabled; create an account at `https://chat.<your-domain>`.

### Email

- **Stalwart:** Configure the [Stalwart secret](charts/services/templates/stalwart.yaml) with S3 credentials and an admin password, then open `https://mail.<your-domain>`.
- **AWS relay:** Install [aws-smtp-relay](https://github.com/arch-anes/aws-smtp-relay) in your AWS account to relay email to and from Stalwart.
- **Cloudflare:** Do not proxy the `mail.example.org` CNAME through Cloudflare, because its proxy blocks mail traffic. See the [Cloudflare discussion](https://community.cloudflare.com/t/emails-blocked-since-cloudflare-firewall-applied/659995).
- **DNS records:** Open `https://mail.<your-domain>/manage/dns/<your-domain>/view` to download a zone file. Skip the `mail` MX and TXT records and TLSA records; add a `mail-ses` MX record for `inbound-smtp.<aws-region>.amazonaws.com` and `mail-ses` TXT records with `v=spf1 include:amazonses.com ~all`. See the [AWS SES](https://docs.aws.amazon.com/ses/latest/dg/eb-ingress.html) and [Stalwart](https://stalw.art/docs/install/dns) references.

## Backup and disaster recovery

### PostgreSQL restore from scratch

Use this when the cluster is lost and needs to be recreated from the remote backup. Add a `dataSource` block to the `PostgresCluster` manifest before applying it:

```yaml
        spec:
          dataSource:
            pgbackrest:
              stanza: db
              configuration:
                - secret:
                    name: postgresql-backup-credentials
              options:
                - --type=time
                - --target="2021-06-09 14:15:11-04"
              global:
                compress-level: '1'
                compress-level-network: '1'
                compress-type: zst
                repo1-s3-uri-style: path
                repo1-cipher-type: aes-256-cbc
              repo:
                name: repo1
                {{- .Values.applications.postgresql.remoteBackupLocation | toYaml | nindent 16 }}
```

Remove the `dataSource` block once the cluster is running to prevent it from re-triggering on the next reconcile.

### PostgreSQL point-in-time recovery

To recover a running cluster to a specific time, add this restore configuration to the `PostgresCluster` manifest:

```yaml
        spec:
          backups:
            pgbackrest:
              restore:
                enabled: true
                repoName: repo1
                options:
                  - --type=time
                  - --target="2021-06-09 14:15:11-04"
```

Trigger the restore, then disable it after recovery completes:

```
kubectl annotate -n default postgrescluster postgresql --overwrite \
  postgres-operator.crunchydata.com/pgbackrest-restore="$(date)"
```

Once recovery is complete, disable the restore to prevent it from re-triggering:

```yaml
spec:
  backups:
    pgbackrest:
      restore:
        enabled: false
```

See the [Crunchy Data recovery reference](https://access.crunchydata.com/documentation/postgres-operator/latest/tutorials/backups-disaster-recovery/disaster-recovery#perform-an-in-place-point-in-time-recovery-pitr).

### Velero

With an S3-compatible bucket configured, Velero and Kopia back up the cluster and selected volumes. Use Kopia or the Kopia UI to browse backed-up files, configured with the bucket, its `keyID` and `keySecret`, the repository encryption key, and the `kopia/default/` prefix. See the [Velero restore reference](https://velero.io/docs/v1.16/restore-reference/).

### Traefik TCP router

When using a TCP router, set proxy protocol version 2:

```
  proxyProtocol:
    version: 2
```
