Redis Setup

Redis is required. Kener will not start without REDIS_URL.

Quick configuration

Add this to .env:

REDIS_URL=redis://localhost:6379

Use rediss:// when your provider requires TLS.

Minimum server sizing (CPU/RAM)

Redis service sizing

Kener app sizing impact (with Redis enabled)

Connection formats

redis://[username:password@]host[:port][/database]
rediss://[username:password@]host[:port][/database]

Examples:

REDIS_URL=redis://localhost:6379
REDIS_URL=redis://:password@localhost:6379
REDIS_URL=rediss://default:password@your-endpoint:6379

Requirements

• Redis 6.0+ (7.0+ recommended)
• Standard read/write commands enabled
• Network access from Kener to Redis host/port

Verify connection

redis-cli -u $REDIS_URL ping

Expected response: PONG

Troubleshooting

• REDIS_URL is not defined: add REDIS_URL to .env and restart.
• NOAUTH Authentication required: include password in the URL.
• Connection timeout: verify host/port/firewall and Redis service status.
• READONLY: connect to primary/writer instance, not a read replica.
