Securing Redis with ACLs and Integrating Redis Insight in Docker
- Securing Redis deployment with ACLs is essential for various use cases such as caching, messaging, and data storage.
- Redis 6 introduced an Access Control List (ACL) system to restrict commands and keys per user.
- Enabling ACLs can pose challenges for monitoring tools like Redis Insight, which may try to connect without credentials.
- Redis Insight does not connect by default when ACLs are enabled, as the default user lacks permissions.
- Writing a valid users.acl file is essential for defining user permissions accurately in Redis ACL configurations.
- Ensure correct syntax for each user, including username, status (on/off), password, key pattern, and command/category permissions.
- Examples of valid ACL lines include disabling default user, creating users for Insight and application, and specifying full permissions.
- Deploying Redis with ACLs in Docker involves creating a separate container for Redis with ACLs enabled and another for Redis Insight.
- Verify ACLs are loading properly in Docker containers by checking Redis logs for any errors and testing connections with redis-cli.
- Deploying Redis Insight in Docker includes removing old containers, running Redis Insight on the same network, and verifying its functionality.
