redis_config function

Redis configuration

Create a set of valid Redis configuration options.

redis_config(..., config = list(...))

Arguments

• ...: See Details
• config: A list of options, to use in place of ...

Details

Valid arguments here are:

• url: The URL for the Redis server. See examples. (default: Look up environment variable REDIS_URL or NULL).
• host: The hostname of the Redis server. (default: 127.0.0.1).
• port: The port of the Redis server. (default: 6379).
• path: The path for a Unix socket if connecting that way.
• password: The Redis password (for use with AUTH). This will be stored in plain text as part of the Redis object. (default: NULL).
• db: The Redis database number to use (for use with SELECT. Do not use in a redis clustering context. (default: NULL; i.e., don't switch).
• timeout: The maximum number of milliseconds to wait for the connection to be established. (default: NULL; i.e. wait forever).

The way that configuration options are resolved follows the design for redis-rb very closely.

1. First, look up (and parse if found) the REDIS_URL

   environment variable and override defaults with that.

2. Any arguments given (host, port, password, db) override values inferred from the url or defaults.

3. If path is given, that overrides the host/port settings and a socket connection will be used.

Examples

# default config:
redis_config()

# set values
redis_config(host = "myhost")

# url settings:
redis_config(url = "redis://:p4ssw0rd@myhost:32000/2")

# override url settings:
redis_config(url = "redis://myhost:32000", port = 31000)
redis_config(url = "redis://myhost:32000", path = "/tmp/redis.conf")
