All three modes share the same set of configuration fields. The sections below explain those fields, then show how to apply them for each mode.
Supported Versions
- Tyk 5.3 and later supports Redis 6.2.x, 7.0.x, and 7.2.x.
- Tyk 5.2.x and earlier supports Redis 6.0.x and Redis 6.2.x only.
Configuration Reference
Tyk Gateway and Tyk Pump configure Redis inside a named object (storage for Tyk Gateway, analytics_storage_config for Tyk Pump). Tyk Dashboard uses top-level fields prefixed with redis_. The underlying options are equivalent.
The table below covers all common configuration fields. TLS-specific fields are covered separately in TLS Encryption.
Address Configuration
- For a single-node connection, use
hostandport. - For Redis Cluster, use
addrswith the addresses of all cluster nodes (both primary and replica). - For Redis Sentinel, use
addrswith the addresses of your Sentinel nodes, not the Redis data nodes directly. - When
addrsis set,hostandportare ignored.
Connection Pool
Each Tyk component maintains a pool of connections to Redis. Two settings control this pool: the maximum number of active connections (optimisation_max_active) and the connection timeout (timeout), after which an attempt to connect to Redis is abandoned.
The defaults (optimisation_max_active: 500, timeout: 5 seconds) are suitable for most deployments. If you are running Tyk under high load and see connection pool timeouts, raise optimisation_max_active (or redis_max_active for Tyk Dashboard) incrementally until the timeouts stop. Avoid setting it excessively high, as opening too many connections can place unnecessary load on Redis. Keep timeout low so that failures are detected quickly rather than queuing behind slow connections.
Single Node Configuration
Use these settings when connecting to a standalone Redis instance. This is the simplest configuration and is appropriate for development or where your Redis provider exposes a single endpoint.Tyk Gateway
Intyk.conf (or via environment variables), Redis is configured inside the storage block:
Tyk Dashboard
Intyk_analytics.conf (or via environment variables), Redis settings are top-level fields:
Tyk Pump
Inpump.conf (or via environment variables), Redis is configured inside the analytics_storage_config block:
Configure Redis Cluster
Redis Cluster automatically shards data across multiple nodes, providing horizontal scalability. It is suited to high-throughput deployments or where the dataset is too large for a single node. Redis Cluster is not the same as a primary/replica setup. In a primary/replica setup, all nodes hold the full dataset and replicas serve as failover targets. In Redis Cluster, the dataset is split across shards, and each shard has its own primary and optional replicas. We recommend reviewing this tutorial to learn more about Redis Cluster. The key differences from a single-node configuration are:- Set
enable_clustertotrue. - Replace
host/portwithaddrs, listing all cluster node addresses. Tyk needs visibility of the full cluster to route correctly. Do not list only the primary nodes.
When connecting to Amazon ElastiCache in cluster mode, you can use the configuration endpoint in
addrs instead of listing individual nodes. The configuration endpoint handles routing automatically and supports both read and write operations.Tyk Gateway
Intyk.conf (or via environment variables), Redis is configured inside the storage block. Set enable_cluster to true and list all cluster nodes under addrs:
Tyk Dashboard
Intyk_analytics.conf (or via environment variables), Redis settings are top-level fields. Set enable_cluster to true and list all cluster nodes under redis_addrs:
The
enable_cluster field does not have the redis_ prefix.Tyk Pump
Inpump.conf (or via environment variables), Redis is configured inside the analytics_storage_config block. Set enable_cluster to true and list all cluster nodes under addrs:
Configure Redis Sentinel
Redis Sentinel provides high availability for a primary/replica Redis setup. Sentinel nodes monitor the primary, and if it becomes unavailable they coordinate promotion of a replica to primary. No change to Tyk’s configuration is required when a failover occurs. Sentinel is the right choice when you need automatic failover but do not need the horizontal sharding that Redis Cluster provides. We recommend reviewing this tutorial to learn more about Redis Sentinel. The key differences from a single-node configuration are:- List your Sentinel node addresses under
addrs(not the Redis data nodes directly). - Set
master_nameto the name of the monitored primary, as configured in your Sentinel setup.
Do not set
enable_cluster: Sentinel and Cluster are mutually exclusive modes.Tyk Gateway
Intyk.conf (or via environment variables), Redis is configured inside the storage block. Point addrs at your Sentinel nodes and set master_name to the name of the monitored primary:
- If your Sentinel nodes require a password, set
sentinel_password.
Tyk Dashboard
Intyk_analytics.conf (or via environment variables), Redis settings are top-level fields. Point redis_addrs at your Sentinel nodes and set redis_master_name to the name of the monitored primary:
- If your Sentinel nodes require a password, set
redis_sentinel_password.
Tyk Pump
Inpump.conf (or via environment variables), Redis is configured inside the analytics_storage_config block. Point addrs at your Sentinel nodes and set master_name to the name of the monitored primary:
- If your Sentinel nodes require a password, set
sentinel_password.
TLS Encryption
Redis supports TLS encryption from version 6. TLS configuration uses the same fields regardless of whether you are using single-node, Cluster, or Sentinel mode.Configuration Fields
TLS fields are configured inside thestorage block for Tyk Gateway, the analytics_storage_config block for Tyk Pump, and as top-level fields prefixed with redis_ for Tyk Dashboard. Note that Tyk Pump uses different field names from Tyk Gateway for most TLS settings.
- Valid values for min/max version:
"1.0","1.1","1.2","1.3". Defaults: minimum"1.2", maximum"1.3". - Setting
ssl_insecure_skip_verifytotrueis not recommended for production.
Example: Mutual TLS
The following example configures Tyk Gateway to use mutual TLS (mTLS) when connecting to Redis:- TLS is enabled with
use_ssl. - The Redis server’s certificate is verified against the provided CA with
ca_file. - Tyk Gateway’s client certificate (
cert_file) and private key (key_file) are used to satisfy Redis’s client authentication requirement.
redis_ (for example, redis_use_ssl, redis_ca_file). For Tyk Pump, these fields sit inside the analytics_storage_config block, but use different field names: for example, ssl_ca_file instead of ca_file. See the table above for the full field mapping.
For background on TLS and mTLS concepts, see TLS and Certificate Management.
Troubleshooting
Before adjusting Tyk configuration, verify that Redis itself is healthy. The commands below help diagnose problems across all deployment modes. Check Redis Is ReachablePONG. If this fails, the connection problem is at the network or Redis level, not in Tyk configuration.
