Can I use redis-cli with a connection URL?

Question

I am used to psql which I can use by feeding it the connection string without having to break it in different arguments, that is,

psql postgres://<username>:<password>@<host>:<port>

This is useful when I have such string from Heroku, for example. Can I do something similar with redis-cli? I want to feed it directly a connection string, such as the one that is stored on Heroku as environment variable when I install a Redis add-on. Is that possible? Example of the syntax I would like to use:

redis-cli redis://<username>:<password>@<host>:<port>

Solution 1

No, at the moment (v3.2.1) redis-cli does not support the URI connection schema. If you want, you can make a feature or pull request for that in the Redis repository.

UPDATE: The -u option was released with Redis 4.0, see Release notes. For example:

redis-cli -u redis://user:pass@host:6379/0

Solution 2

For those who cannot wait for the next Redis release won't be able to update their redis-cli, I made a simple bash function that seems to work for my case (Heroku). This is to be added to ~/.bash_profile or ~/.bashrc:

function redis-url() {
  # Get the first argument as the URL variable
  url=$1
  # Parse and generate the command: redis-cli -h [hostname] -p [port] -a [password]
  cmd=`echo $url | sed 's_redis://\(.*\):\(.*\)@\(.*\):\(.*\)_redis-cli -h \3 -p \4 -a \2_'`
  # Run the command
  $cmd
}

I can then type the following in my terminal:

redis-url redis://rediscloud:[email protected]:1234
