Getting Started Tutorial with Redis Enterprise Software using Docker on macOS
To get started with a single Redis Enterprise Software container on macOS, follow these steps:
- Step 0: Install Docker
- Step 1: Run the container
- Step 2: Setup a cluster
- Step 3: Create a new database
- Step 4: Connect to your database
You can also visit Docker Hub for instructions on getting Docker installed and working with the Redis Enterprise Software Docker container image.
Step-by-Step Guide for Redis Enterprise Software on macOS
Step 1: Run the Container
Run the Redis Enterprise Software Docker container by executing the following command at the Terminal window.
Redis Enterprise Software utilizes a Linux based container. Make sure that your macOS machine is running Linux containers.
$ docker run -d --cap-add sys_resource --name rp \ -p 8443:8443 -p 12000:12000 redislabs/redis
Step 2: Set Up a Cluster
Direct your browser to https://localhost:8443/ on the host machine to see the Redis Enterprise Software web console. Simply click the Setup button on the page to get started.
On the node configuration page, select your default settings and provide a cluster FQDN: “cluster.local”. Then simply click the Next button.
If you don’t have a license key, click the Next button to try the trial version of the product.
On the next screen, set up a Cluster Administrator account using an email for the login and a password.
Step 3: Create a Database
Choose the new redis db option.
On the new redis db page, click the show advanced options link and enter “database1” for the database name and 12000 for the endpoint port number. Then click Activate to create your database.
You now have a Redis database!
Step 4: Connect to your Database
With the Redis database created, you are ready to connect to your database to store data. You can use one of the following ways to test connectivity to your database
- Connecting with redis-cli, the built-in command-line tool.
- Connecting with a “hello world” application using Python.
Connecting Using redis-cli
redis-cli is a simple command-line tool to interact with redis database.
Use “docker exec” to switch your context into the Redis Enterprise Software container
$ docker exec -it rp bash
Run redis-cli, located in the /opt/redislabs/bin directory, to connect to port 12000 and store and retrieve a key in database1
$ sudo /opt/redislabs/bin/redis-cli -p 12000 127.0.0.1:16653> set key1 123 OK 127.0.0.1:16653> get key1 "123"
Connecting Using “Hello World” Application in Python
A simple python application running on the host machine, not the container, can also connect to database1.
In the command-line Terminal, create a new file called “redis_test.py”
$ vi redis_test.py
Paste the following into a file named “redis_test.py”.
import redis r = redis.StrictRedis(host='localhost', port=12000, db=0) print ("set key1 123") print (r.set('key1', '123')) print ("get key1") print(r.get('key1'))
Run “redis_test.py” application to connect to the database and store and retrieve a key using the command-line.
$ python redis_test.py
The output should look like the following screen if the connection is successful.
set key1 123 True get key1 b'123'
