Redis logger module for Caddy

This plugin sends Caddy logs to Redis using the LPUSH command, allowing other consumers to process the logs.

• It helps address issues related to centralized log collection and the I/O and storage challenges of keeping logs locally.
• It's particularly suited for small-scale operations deployed on VPS.
• In the future, if scaling is needed, you can consider using Redis Cluster or DragonflyDB.

通过本插件，可把caddy日志通过LPUSH发送给redis, 以供其他消费端处理。

• 它可以解决日志收集中心化、本地日志存储带来的io和容量问题。
• 比较适合部署在VPS上的小规模业务。
• 未来如果要扩容，可以考虑Redis Cluster或Dragonflydb

Configuration

Simple mode

Enable Redis logger for Caddy by specifying the module configuration in the Caddyfile:

{
    order redis_logger after log
}

:80 {
    route {
        redis_logger my_redis_key {
            redis_address localhost:6379
            redis_password mypassword
            with_request_body
        }
        respond "Hello, World!"
    }
}

Note that address and db values can be configured (or accept the defaults) .

The module supports environment variable substitution within Caddyfile parameters:

{
    redis_logger my_redis_key {
        redis_address        "{$REDIS_ADDRESS}"
        redis_password       "{$REDIS_PASSWORD}"
    }
}

NOTE however the following configuration options also support runtime substition:

• redis_db // default 0
• dial_timeout // 连接超时时间 default 5s
• write_timeout // 写入超时时间 default 3s
• max_retries // 最大重试次数 default 3

Not support

• Redis Cluster
• Failover mode
• TLS
