Redis Config Generator

Generate optimized redis.conf files. Tune memory eviction policies, configure RDB/AOF persistence, and secure your Redis instances.

Output:A ready-to-use configuration file for Redis Config with best practices applied.

Redis Version

Target Version

Network & Connection

Bind Address

Use 127.0.0.1 for local, or specific private IPs. Do NOT use 0.0.0.0 without a firewall.

Port

Protected Mode

Security & TLS

Require Password

Plaintext password. If left blank, it's highly recommended to inject via ENV vars instead.

Memory Management

Max Memory

e.g., 2gb. If empty, Redis will consume all available system RAM.

Eviction Policy

Persistence (RDB & AOF)

RDB Save Rules

Format: 'seconds changes'. E.g. '3600 1' saves every hour if 1 key changed. Leave blank to disable RDB.

Working Directory

Where AOF/RDB files are stored. E.g., /var/lib/redis.

Enable AOF (Append Only File)

Quick Summary

Use a Redis Config Generator when you need a redis.conf file for binding, authentication, persistence, maxmemory, eviction policies, Redis 6/7 options, or Kubernetes ConfigMap setup.

What is this tool?

The redis.conf file is the main configuration file for a Redis server instance. It determines how Redis operates in terms of networking, security, memory limits, and disk persistence.

Redis Configuration Options

bind: Specifies which network interfaces Redis listens on. By default, it usually binds to localhost (127.0.0.1 -::1) for safety.
port: The default TCP port is 6379.
requirepass: The password required to authenticate default clients. Essential if your instance is accessible over a network.
protected-mode: A safety feature. If enabled, and no bind or password is set, Redis only accepts local connections.
maxmemory: The maximum amount of RAM Redis is allowed to use. Once reached, Redis uses the maxmemory-policy to decide what to do.
maxmemory-policy: The eviction policy. Common options include noeviction (return errors), allkeys-lru (evict least recently used keys - great for caches), or volatile-lru.
save: Controls RDB persistence (snapshots). E.g., save 3600 1 300 100 60 10000.
appendonly: Enables AOF (Append Only File) persistence for higher durability at the cost of disk I/O.

How to Use This Tool

Redis Commands

You don't always need to edit the config file directly. You can use CONFIG SET <parameter> <value> in the redis-cli to change settings dynamically, and then run CONFIG REWRITE to flush those changes back to redis.conf.

Platform Specific Configurations

Linux / Ubuntu: Usually found at /etc/redis/redis.conf.
Docker: Start the container with redis-server /usr/local/etc/redis/redis.conf and mount your file there.
Spring Boot: In Spring applications, you configure connections via application.yml under spring.data.redis, but you still need a redis.conf for the server itself.

Security Notes

Do not expose Redis publicly. If you bind to 0.0.0.0, anyone on the internet can scan and connect to port 6379. Use firewalls.
Always use requirepass or ACL users. An unprotected Redis instance is a massive security risk and can easily be exploited to gain remote code execution on the host.
Do not put real passwords in generated examples. Use placeholders in online generators.
Use TLS where required. Since Redis 6, native TLS/SSL support is available if you compile with it. Enable it for cross-datacenter traffic.

Frequently Asked Questions

What is a Redis Config Generator?

A Redis Config Generator is an online tool that produces a secure redis.conf file. It helps you quickly configure memory limits, eviction policies, persistence (RDB/AOF), and authentication without needing to read the entire default configuration template.

How do I create redis.conf?

Use our generator to define your binding IP, password, memory limits, and persistence needs. Then, copy the generated output and place it on your server, typically at /etc/redis/redis.conf.

How do I view Redis config?

You can view the running configuration by connecting to Redis via redis-cli and running the command: CONFIG GET *

What is Redis CONFIG GET?

The CONFIG GET command allows you to retrieve the current value of configuration parameters dynamically while the Redis server is running.

How do I set Redis password?

In redis.conf, use the 'requirepass' directive (e.g., requirepass my_strong_password) for default users. In Redis 6+, you can also configure robust ACL (Access Control List) rules for multiple users.

What is Redis CONFIG REWRITE?

If you change settings dynamically using CONFIG SET, they are lost on restart. Running CONFIG REWRITE saves those dynamically changed settings back into the redis.conf file permanently.

Can I generate Redis ConfigMap?

Yes. Simply paste the generated redis.conf content into the data block of a Kubernetes ConfigMap and mount it to /usr/local/etc/redis/redis.conf inside your container.

What changed in Redis 7 config?

Redis 7 introduced Multi-Part AOF (Append Only File) which changes how persistence logs are stored. It also enhanced ACLs and function capabilities.

How We Keep Your Configs Safe & Valid

Built-in Error Checking

Every file is checked against official rules. We catch missing fields and bad syntax. YAML indentation errors are flagged right away. Kubernetes, Terraform, and Docker specs are all covered. API versions and labels are verified too. You get valid output every time you generate.

100% Private & Local

All tools run in your browser only. Your API keys never leave your machine. We do not use any tracking scripts. No data is sent to any server. Passwords and secrets stay on your device. Crypto operations use the Web Crypto API. Your privacy is fully protected at all times.

Secure Settings by Default

Configs use safe defaults out of the box. Containers run as non-root users. Root filesystems are set to read-only. Dangerous Linux capabilities are dropped. Network policies limit pod-to-pod traffic. TLS 1.3 is enabled for web servers. Security headers are added where needed.

Ready for CI/CD & Git

Output files are ready for your Git repo. Use them with ArgoCD, Flux, or GitHub Actions. Files use clear formatting and comments. Code review is easy for your team. Indentation and key order are consistent. Test in staging before going to production. Every file is clean and well-structured.

Infrastructure as Code

Store configs in Git alongside your code. Terraform modules include typed variables. Backend configs support remote state locking. Outputs work across multiple modules. Ansible playbooks use clear task steps. Chef and Puppet configs are also supported. Every file works with version control tools.

Monitoring & Tracing

Set up Prometheus with auto-discovery rules. Create Grafana dashboards with template variables. Add alerting rules with severity labels. Use OpenTelemetry for trace collection. Forward logs to Loki or Elasticsearch. Connect to Jaeger or Tempo for tracing. Monitor metrics, logs, and traces together.

Container & Docker Safety

Dockerfiles use multi-stage builds for small images. Base images are pinned to exact versions. Dev files are excluded from final images. Health checks are added for orchestrator use. Containers switch to non-root users. Docker Compose uses named volumes and networks. Resource limits are set in deploy configs.

Multiple Output Formats

Export as YAML, JSON, HCL, or TOML. Kubernetes uses YAML with proper separators. Terraform uses HCL with correct escaping. JSON output has consistent indentation. Copy to clipboard with one click. Preview output with syntax highlighting. Line numbers help you review quickly.
