My goal is to connect Redis to my server using Docker containers. From reading documentation I have utilized the following code. I have read multiple sources to try to find an answer and am coming up short. I have tried creating my own dockerfile-redis but npm is not able to install redis. StackExchange.Redis automatically tries to reconnect in the background when the connection is lost for any reason. It keeps retrying until the connection has been restored. It would use ReconnectRetryPolicy to decide how long it should wait between the retries. ReconnectRetryPolicy can be linear (default), exponential or a custom retry policy.

Redis is a very popular data store used across all kinds of web apps it’s supported natively by Mac and Linux operating systems. Heck, you can even use Docker to run Redis.

The purpose of this guide is to setup Redis so we can use in our Python applications including Django, Flask, Fastapi, Celery, and pure python apps.

These didn't generate any errors; however, it appears that Redis does not start. If I run redis-cli ping, I get back Could not connect to Redis at 127.0.0.1:6379: Connection refused. I can manually run redis-server in another terminal window, but I'd like to have Redis auto-start on login.

Do you need to use Redis on Docker? The windows install guide shows you how.

3.1. Install Redis on macOS¶

Redis Connection Refused Mac Catalina

3.1.1. Install Homebrew¶

Redis Connection Refused

3.1.2. Install redis¶

Every once and a while run brewupgraderedis

3.1.3. Start / Stop Redis¶

Starting redis this way turns redis into a background service. You can easily stop redis with:

3.1.4. Verify redis is running:¶

What result do you see?

PONG – great, redis is working and ready.
CouldnotconnecttoRedisat127.0.0.1:6379:Connectionrefused – this means that: (1) you did not install redis correctly or (2) redis is not running.

3.2. Install Redis on Linux (using Ubuntu)¶

Below was adapted from the production-ready guide in our series Hello Linux

3.2.1. Update System¶

3.2.2. Install `redis-server`¶

3.2.3. Update configuration¶

Update supervised to the following:

Save and exit nano.

Restart running service:

3.2.4. Verify installation:¶

What result do you see?

PONG – great, redis is working and ready.
CouldnotconnecttoRedisat127.0.0.1:6379:Connectionrefused – this means that: (1) you did not install redis correctly, (2) redis is not running, or (3) the system service did not start (check with sudosystemctlstatusredis)

3.3. Install on Windows 10 using Docker¶

Naturally, you need to install docker desktop on your windows 10. There’s a huge caveat that might push you towards using Memurai:

Docker requires you to have Windows 10 professional

Windows 10 professional allows for the OS virtualization that is just not provided in Windows 10 home.

Are you new to docker? Check out this basic intro

3.3.1. Verify Docker¶

Open PowerShell and run:

3.3.2. Create a project directory¶

3.3.3. Update (or create) a `Dockerfile`¶

You don’t have to build the redis image yourself but I prefer to so I can make changes easily and it’s already prepared for it.

3.3.4. Build our docker image:¶

Personally, I like adding commands like dockerbuild-t'cfe-redis'. to a build.ps1 file so I can just call ./build.ps1 if I ever want to build it again in the future.

3.3.5. Run our docker image:¶

A couple things to note:

-it--rm is so this docker container only runs when we want it to and the container will be removed after we’re done running it.

-p6379:6379 is exposing the port 6379 on our local system AND in our docker container.

cfe-redis is merely the tag name of the image we created in the build process.

Just like with build.ps1, make a run.ps1 file containing dockerrun-it--rm-p6379:6379'cfe-redis' as a shortcut to running this container.

3.3.6. Verify Docker connection¶

On Linux and Mac, you can just run redis-cliping but, since we’re using docker, we don’t have the redis-cli command available on our system.

We need another way to test. Since I use redis in my Python projects, I’ll create a simple python program to ensure our non-container items can connect to redis.

I already have Python 3.8 installed. If you don’t, check out this guide.

3.3.6.1. Create virtual environment¶

You can use pipenv as well. I’m just keeping things simple by using the built-in virtual environment manager

3.3.6.2. Activate virtual environment¶

3.3.6.3. Run `pipinstallredis`¶

This command does not install the redis server; it just installs a redis connector that we can use in python.

3.3.6.4. Create `ping_redis.py`¶

Notice the port=6379 I used? This is the default redis port and it matches to what I exposed above.

3.3.6.5. Run `ping_redis.py`¶

What result do you have?

Trueb'bar' – this means redis is running correctly
Noconnectioncouldbemadebecausethetargetmachineactivelyrefusedit. – this means your version of redis is either (1) not running or (2) running incorrectly or (3) you got the port number wrong.

3.3.7. Future running¶

Now, whenever you need to use redis in your projects. Just run:

Anywhere on your system.

3.4. Install Redis on Windows using Memurai.com¶

I haven’t used memurai much myself but it seems promising. Let’s see

3.4.2. Run downloaded installer¶

3.4.3. Agree to all defaults except port.¶

For the port, I’ll use 6380.

I’m leaving 6379 open. It’s the default redis port and I’m not 100% convinced I’ll use memurai in the future. I’m positive I’ll use Docker and so I’ll leave 6379 open for docker versions of redis like above.

3.4.4. Verify in Python – Create a virtual environment.¶

memurai should be running by default after you installed it so we need to verify.

Assuming you did not do the docker portion above, let’s create a new virtual environment to test redis is running via memurai. Open up PowerShell and run:

I already have Python 3.8 installed. If you don’t, check out this guide.

3.4.4.1. Activate virtual environment¶

3.4.4.2. Run `pipinstallredis`¶
