Management server

Review how the Gloo management server backs up data and your setup options to make the backing database more resilient.

What data gets stored

The Gloo snapshot that the agent sends to the management server is stored in the management server’s backing storage. For an example of how to check the data that gets stored, see Review data in Redis.

Discovered Kubernetes resources, such as Kubernetes services, deployments, replicasets, daemonsets, and statefulsets.
Gloo custom resources that you create. The management server translates Gloo resources and displays them in the Gloo UI.
Internal resources that are computed in memory by each agent and pushed to the management server without being persisted in the workload cluster. Internal resources include:
- Gateway resources, which contain information about gateway endpoints in the cluster.
- IssuedCertificate and CertificateRequest resources, which are used in internal multi-step workflows that involve both the agent and the management server.

Backing storage options

Review the following options for setting up backing storage with Redis®* ¹ instances.

Option	Use case	Benefits	Drawbacks
Built-in local Redis	Proof of concept and staging environments	Default setup, automatically works Fast read/write speed as the instance is local to the management server Updatable via Gloo Platform Helm chart	Only as highly available as your cluster setup Has the same disaster recovery as your cluster setup Might not meet your organization’s compliance requirements
Bring your own Redis	Production environments	Enhanced high availability and disaster recovery (HA/DR) Service level agreement (SLA) from your provider Meet your organization’s compliance requirements	More complicated setup Not covered by Solo support (contact your external Redis provider)

Shared or separate instances

In Gloo Network, many components use Redis to store data. Several of these components must share the same instance in order to function properly, as follows:

Management server, UI, and insights engine (which is also used as part of the OTel pipeline).
External auth service and developer portal server.
Rate limiter, which is often shared with the external auth service and portal server, but does not have to be.

If you enable the default, Solo-provided, local Redis options, these Redis instances are created separately.

If you bring your own Redis, you can choose to share the Redis instances or not. For internal compliance or security purposes, you might want separate Redis instances for each of these use cases. As such, the following guide assumes a separate deployment, and uses separate secrets. However, you can also share a single external Redis instance and update the names accordingly.

Built-in local Redis

By default, a local Redis instance gloo-mesh-redis is set up in the gloo-mesh namespace of the management cluster when you install the Gloo management server and UI components. The Gloo management server replicas and the Gloo UI are automatically configured to read from and write data to this Redis instance for a global view of your Gloo environment.

info

Using a local Redis instance is not a recommended practice for production. To achieve higher availability, disaster recovery and add other security features, bring your own Redis instance instead.

When you install or upgrade Gloo Network, include the following Helm values to enable the local Redis instance.

  
redis:
  deployment:
    # Enable the creation of the local Redis deployment and service.
    enabled: true

Optional: Further configure the default Redis values, such as to modify the Kubernetes deployment’s resource limits and requests. For more information, check the Helm reference for the redis component.
Verify that data is stored in the local Redis instance.

Bring your own Redis

Instead of using the built-in local Redis instance, you can achieve higher availability, disaster recovery, and enhanced control and security by bringing your own Redis cluster.

info

Keep in mind that by bringing your own Redis instance, you configure both the Gloo management server and Gloo UI to read from and write to the same Redis database. Any settings for your Redis instance, such as the maximum number of retries, are shared between these components.

Step 1: Choose a Redis provider

You can choose between a local or externally hosted Redis instance.

For a local instance: Install the Redis instance in the same cluster as the component that the Redis backs. For example, for the Gloo management server, install the Redis instance in the management cluster. For an add-on, install the Redis instance in the same workload as the rate limiter, external auth service, or portal server.
For an external cloud instance: Create an instance outside your cluster environment, such as Redis Enterprise or a cloud provider service like AWS ElastiCache.

info

Using a Redis or AWS ElastiCache instance in cluster mode is currently not supported.

Step 2: Configure your Redis instance

To create or use an existing Redis instance, make sure that you can connect to your Redis instance from the Gloo management cluster. These steps can vary by provider, but the following guidelines are common.

Local instances: The Gloo management server and Redis instances must be able to communicate. For example, you might deploy them in the same Kubernetes namespace.
Cloud instances: Often, you must configure networking settings such as the following:
- Create the Kubernetes cluster and the Redis instance in the same virtual private network (VPC).
- Create the Kubernetes cluster and the Redis instance in the same security group.
- Make sure that the security group allows inbound and outbound connections between the cluster and Redis instance.
- If the cluster is behind a firewall, you might need to add the public IP address of the Redis cluster to your allowlist.
Provider-specific considerations: Continue reading for requirements per Cloud provider.
- AWS Elasticache

AWS ElastiCache

When setting up your AWS ElastiCache instance, consider the following deployment options:

Use a high availability (HA) setup consisting of at least 1 primary and 1 replica instance.
Use non-clustered mode. Cluster mode is currently not supported.
Set up multiple availability zones (multi-AZ) with auto-failover enabled.
Set the maxmemory-policy directive to noeviction. For more information about eviction policies, see the Redis docs.
Use node types with TLS Offloading and Enhanced I/O Multiplexing.
Although optional, enabling TLS is recommended.
Monitor performance metrics including CPU utilization, memory usage, network throughput, and cache hit ratio.

Step 3: Get your Gloo environment details

You can configure Redis during an initial installation or by performing an upgrade. Either way, you can configure the Redis details in your Helm values file.

Installation

If you have not installed Gloo Network yet, prepare details for your installation.

Decide the Helm release namespace to use. The example uses the names suggested throughout the documentation, gloo-platform and gloo-mesh.
```
  export GLOO_MESH_RELEASE_NAMESPACE=gloo-mesh
  
```
Create a Helm values file for your installation, such as gloo-single.yaml for a single cluster or mgmt-plane.yaml and data-plane.yaml for a multicluster environment.

Upgrade

If you are upgrading Gloo Network to set up Redis, get the details of your installation.

Save the details of your Gloo Network installation, including the Helm chart namespace for the component that you want to set up the Redis instance for. In the following example, the release name is gloo-platform and the namespace is gloo-mesh, but you can update your values accordingly.
```
  export GLOO_MESH_RELEASE_NAMESPACE=gloo-mesh
  
```
To get the values for your own release, run the following Helm command.
```
  helm list --all-namespaces
  
```
```
  NAME                 	NAMESPACE       	REVISION	UPDATED                             	STATUS  	CHART
gloo-platform        	gloo-mesh       	1      	  2023-09-01 13:26:56.061102 -0400 EDT	deployed	gloo-platform-2.5.12
  
```

Get your Gloo Platform Helm values file. For more information, see Upgrade guide.

Single cluster:

  helm get values gloo-platform -o yaml -n gloo-mesh > gloo-single.yaml
open gloo-single.yaml

Multicluster:

  helm get values gloo-platform -n gloo-mesh -o yaml --kube-context $MGMT_CONTEXT > mgmt-plane.yaml
open mgmt-plane.yaml

  helm get values gloo-platform -n gloo-mesh -o yaml --kube-context $REMOTE_CONTEXT > data-plane.yaml
open data-plane.yaml

Step 4: Set up Redis authentication

Choose how to authenticate with your Redis cluster. Depending on your Redis provider, you might be required to use a specific authentication method, such as TLS certificates or a username and password.

TLS-encryption

For TLS-encrypted communication with Redis, the steps vary by provider.

Enable TLS encryption for your Redis instance.
- For local instances, you might create your own certificates such as with openssl or cert-manager to make the public Certificate Authority (CA) certificate, ca.crt. Then, you create a secret with this CA certificate so that the Gloo client can establish trust for the TLS connection to the Redis server instance. Note that server-side credentials for a mutual TLS (mTLS) connection are currently not supported.
- For cloud instances, the provider often manages the certificates for you. For example, AWS ElastiCache encrypts in-transit communication with their own public CA. Note: Most up-to-date apps include CA certificates that trust the AWS CA by default. However, if after setup, you notice timeouts and SSL_connect failed: certificate verify failed messages in the logs, your app might not have the CA certificates. Depending on your app, you can update the CA certificates such as by logging into the pod and running update-ca-certificates. For an example, see the Bring your own Redis deployment example in the verification guide.
For local instances: Create a Kubernetes secret to store the TLS credentials in the same namespace as the management server. Run the following command from the local directory where your TLS certificates and key were created. Update the filenames of the certificates as necessary. Note: If you do not have certificates, such as if you use a cloud provider like AWS ElastiCache, skip this step.
```
  kubectl apply -f - <<EOF
apiVersion: v1
kind: Secret
type: Opaque
metadata:
  name: "redis-certs"
  namespace: $GLOO_MESH_RELEASE_NAMESPACE
  labels:
    app.kubernetes.io/managed-by: Helm
  annotations:
    meta.helm.sh/release-name: $GLOO_MESH_RELEASE_NAME
    meta.helm.sh/release-namespace: $GLOO_MESH_RELEASE_NAMESPACE
data:
  ca.crt: $(cat ca.crt | base64 | tr -d '\n')
EOF
  
```

Prepare the redis.certs section of the Helm values file that you previously retrieved.

For local instances, enable the redis.certs section. Include the details of the secret that you previously created.

  
redis:
  certs:
    # Enable TLS connections to the Redis instance.
    enabled: true
    # Name of the Kubernetes secret that has the TLS certs.
    # The secret must be in the same namespace as the management server.
    secretName: redis-certs
    # The key name in the data section of the Kubernetes secret
    # that has the CA certificate.
    caCertKey: ca.crt

For cloud instances like AWS ElastiCache that use a public CA, simply enable the redis.certs section. Omit the secret name and CA cert key fields.

  
redis:
 certs:
   # Enable TLS connections to the Redis instance.
   enabled: true

Password authentication

For a username and password auth, complete the following steps.

Enable password auth for your Redis instance.
Save the following values as environment variables.
- Username: If your Redis instance does not have a username, use default.
- Password: Note the password string.
```
  export REDIS_UN=default
export REDIS_PW=<password>
  
```

Create a Kubernetes secret to store the credentials in the same namespace as the management server.

  kubectl apply -f- <<EOF
apiVersion: v1
kind: Secret
type: Opaque
metadata:
   name: redis-auth-secrets
   namespace: $GLOO_MESH_NAMESPACE
   labels:
     app.kubernetes.io/managed-by: Helm
   annotations:
     meta.helm.sh/release-name: $GLOO_MESH_RELEASE_NAME
     meta.helm.sh/release-namespace: $GLOO_MESH_NAMESPACE
stringData:
  #If Redis doesn't have an explicit username, specify ‘default’.
  username: "$REDIS_UN"
  password: "$REDIS_PW"
EOF

Prepare the redis.auth section of the Helm values file that you previously retrieved.

  
redis:
  auth:
    # Enable authentication for Redis with the username and password in the referenced secret.
    enabled: true
    # The name of the secret in the same namespace as the management server.
    secretName: redis-auth-secrets
    # The key name in the data section of the Kubernetes secret
    # that has the password.
    passwordKey: password
    # The key name in the data section of the Kubernetes secret
    # that has the username.
    usernameKey: username

Step 5: Configure other Redis settings

Complete the redis section of your Helm values file. For more settings, see the Helm reference.

To use your own Redis instance, disable the default Solo-provided Redis.

  
redis:
  deployment:
    # The default deployment of Redis.
    # Set to false to bring your own Redis instance.
    enabled: false

Include the address to use to connect to your Redis cluster.
- For local instances, this value is typically the Kubernetes service name that the management server can access, such as gloo-mesh-redis.gloo-mesh:6379.
- For a cloud instance, this value is typically the primary endpoint, such as master.my-redis-name.cache.amazonaws.com:6379 for AWS ElastiCache or 10.xxx.xx.xx:6379 for Google Cloud Memorystore.
```
  
redis:
  # Provide the address to your external Redis database, such as AWS ElastiCache or Google Cloud Memorystore.
  # The following example shows how to configure the address for a Redis instance that is deployed to the cluster.
  address: gloo-mesh-redis.gloo-mesh:6379
  
```

Optionally override the default connection settings for Redis, such as the maximum number of retries.

  
redis:
  connection:
    # Dial timeout for establishing new connections. Default is 5 seconds.
    dialTimeout: 5s
    # Frequency of idle checks made by idle connections reaper. Default is 1 minute. -1 disables idle connections reaper, but idle connections are still discarded by the client if IdleTimeout is set.
    idleCheckFrequency: 1m0s
    # Amount of time after which client closes idle connections. Should be less than server's timeout. Default is 5 minutes. -1 disables idle timeout check.
    idleTimeout: 5m0s
    # Connection age at which client retires (closes) the connection. Default is to not close aged connections.
    maxConnAge: ""
    # Maximum number of retries before giving up. Default is 3. -1 disables retries.
    maxRetries: 3
    # Maximum backoff between each retry. Default is 512 milliseconds. -1 disables backoff.
    maxRetryBackoff: 512ms
    # Minimum number of idle connections which is useful when establishing new connection is slow.
    minIdleConns: 0
    # Minimum backoff between each retry. Default is 8 milliseconds. -1 disables backoff.
    minRetryBackoff: 8ms
    # Type of connection pool. true for FIFO pool. false for LIFO pool. Note that FIFO has higher overhead compared to LIFO.
    poolFifo: false
    # Maximum number of socket connections. Default is 10 connections per every available CPU as reported by runtime.GOMAXPROCS.
    poolSize: 0
    # Amount of time client waits for connection if all connections are busy before returning an error. Default is ReadTimeout + 1 second.
    poolTimeout: ""
    # Timeout for socket reads. if reached, commands will fail with a timeout instead of blocking. Default is 3 seconds. -1 disables timeout. 0 uses the default value.
    readTimeout: 3s
    # Timeout for socket writes. If reached, commands will fail with a timeout instead of blocking. Default is ReadTimeout.
    writeTimeout: ""

Step 6: Upgrade the Helm installation

Continue with the Upgrade guide to reinstall Gloo Network with your own Redis instance. Include the Helm values file that you prepared in the previous steps.

The following example Helm values file shows a simple installation with the Redis section filled out for an AWS ElastiCache instance.

Verify the connection

To review the data that is stored in Redis, you can connect to the local Redis instance. If you bring your own Redis, you must use those connection values. For more information, see your Redis provider docs, such as Amazon ElastiCache or Google Cloud Memorystore.

Choose between using the Redis CLI or RedisInsights.

Redis CLI

You can use the Redis CLI that is built into your deployment to review the data in your database.

Install Redis in your cluster so that you can use the redis-cli to connect to your Redis instance.
Built-in Redis Your own local Redis Your own external Redis
When you install Gloo Network with the default settings, Redis is installed in the cluster for you. You can skip this step.
To connect to your own local Redis instance, make sure to get its details, such as my-redis in a redis namespace, as well as any authentication details.
To connect your own external Redis in a cloud instance, such as AWS ElastiCache:
1. Deploy the Redis CLI, such as with the following simple deployment. For more information, see the Redis docs.
  kubectl apply -f - <<EOF apiVersion: apps/v1 kind: Deployment metadata: name: redis-cli labels: app: redis-cli spec: replicas: 1 selector: matchLabels: app: redis-cli template: metadata: labels: app: redis-cli spec: containers: - name: redis-cli image: redis:latest command: ["sleep", "infinity"] # Keeps the container running indefinitely EOF
2. Verify that you can access the Redis pod by logging into the pod.
  kubectl exec -it deploy/redis-cli -- /bin/sh
3. Optional: For TLS connections that use a public CA, such as for AWS ElastiCache, make sure that the Redis CA certificates are up to date.
  apt-get install ca-certificates
4. Verify that the CA certificates are installed.
  ls /etc/ssl/certs
  Example truncated output:
  002c0b4f.0 02265526.0 ... Amazon_Root_CA_1.pem Amazon_Root_CA_2.pem Amazon_Root_CA_3.pem Amazon_Root_CA_4.pem ...
From your terminal, log in to the Redis pod and open a Redis CLI shell.
Built-in redisStore Built-in Redis for add-ons Your own local Redis Your own external Redis
You can open a Redis CLI shell session by logging in to the Redis instance in the gloo-mesh namespace, such as gloo-mesh-redis which backs the Gloo management server and UI.
```
  kubectl exec -n gloo-mesh deploy/gloo-mesh-redis -it -- redis-cli
  
```
You can open a Redis CLI shell session by logging in to the Redis instance in the add-ons namespace, such as redis in the gloo-mesh namespace, which backs the rate limiter, external auth, or portal server add-ons.
```
  kubectl exec -n gloo-mesh deploy/redis -it -- redis-cli
  
```
You can open a Redis CLI shell session by logging into the Redis pod with the details that you got in the previous step. Include the --tls flag if your Redis instance enforces a TLS connection. Include the -a flag with your password if your Redis instance enforces auth.
```
  kubectl exec -n redis deploy/my-redis -it -- redis-cli --tls -a 'my-password'
  
```
You can open a Redis CLI shell session by logging into the redis-cli pod that you deployed in the previous step. Update the host with your cloud instance details. Include the --tls flag if your Redis instance enforces a TLS connection. Include the -a flag with your password if your Redis instance enforces auth.
```
  kubectl exec -n default deploy/redis-cli -it -- redis-cli -h master.<my-redis>.abcdefg.use2.cache.amazonaws.com --tls -a 'my-password' -p 6379
  
```

Run Redis CLI commands, such as monitor or keys. For more information, see the Redis docs.
