## `redis`
Declare parameters for constructing the `redis` connections. Registry instances
may use the Redis instance for several applications. Currently, it caches
information about immutable blobs. Most of the `redis` options control
how the registry connects to the `redis` instance.
You should configure Redis with the **allkeys-lru** eviction policy, because the
registry does not set an expiration value on keys.
Under the hood distribution uses [`go-redis`](https://github.com/redis/go-redis) Go module for
Redis connectivity and its [`UniversalOptions`](https://pkg.go.dev/github.com/redis/go-redis/v9#UniversalOptions)
struct.
You can optionally specify TLS configuration on top of the `UniversalOptions` settings.
Use these settings to configure Redis TLS:
| Parameter | Required | Description |
|-----------|----------|-------------------------------------------------------|
| `certificate` | yes | Absolute path to the x509 certificate file. |
| `key` | yes | Absolute path to the x509 private key file. |
| `clientcas` | no | An array of absolute paths to x509 CA files. |
```yaml
redis:
addr: localhost:6379
tls:
certificate: /path/to/cert.crt
key: /path/to/key.pem
clientcas:
- /path/to/ca.pem
addrs: [localhost:6379]

Declare parameters for constructing the `redis` connections. Registry instances
may use the Redis instance for several applications. Currently, it caches
information about immutable blobs. Most of the `redis` options control
how the registry connects to the `redis` instance. You can control the pool's
behavior with the [pool](#pool) subsection. Additionally, you can control
TLS connection settings with the [tls](#tls) subsection (in-transit encryption).
You should configure Redis with the **allkeys-lru** eviction policy, because the
registry does not set an expiration value on keys.
| Parameter | Required | Description |
|-----------|----------|-------------------------------------------------------|
| `addr` | yes | The address (host and port) of the Redis instance. |
| `password`| no | A password used to authenticate to the Redis instance.|
| `db` | no | The name of the database to use for each connection. |
| `dialtimeout` | no | The timeout for connecting to the Redis instance. |
| `readtimeout` | no | The timeout for reading from the Redis instance. |
| `writetimeout` | no | The timeout for writing to the Redis instance. |
### `pool`
```yaml
pool:
maxidle: 16
maxactive: 64
idletimeout: 300s
```
Use these settings to configure the behavior of the Redis connection pool.
| Parameter | Required | Description |
|-----------|----------|-------------------------------------------------------|
| `maxidle` | no | The maximum number of idle connections in the pool. |
| `maxactive`| no | The maximum number of connections which can be open before blocking a connection request. |
| `idletimeout`| no | How long to wait before closing inactive connections. |
### `tls`
```yaml
tls:
enabled: false
```
Use these settings to configure Redis TLS.
| Parameter | Required | Description |
|-----------|----------|-------------------------------------- |
| `enabled` | no | Whether or not to use TLS in-transit. |
## `health`
