How to Start redis-server with docker-compose up

Setting up efficient environments for development can sometimes come with its own set of challenges. If you’re using Docker and need to run a Redis server alongside your application server, you may be wondering how to streamline the process. Currently, many developers find themselves spinning up a container only to manually start the Redis server inside it. This can be both time-consuming and inefficient.

In this post, we'll address how to start Redis automatically with the rest of your stack using a docker-compose setup. Let's dive into the solution step-by-step.

The Problem

You are using pipenv to run your application, but want to eliminate the hassle of manually starting Redis after spinning up your container. There’s a simpler way: by utilizing Docker Compose, you can manage multiple services conveniently, ensuring that Redis starts automatically when you run docker-compose up.

The Solution

To achieve this, you need to modify your existing docker-compose.yml file to include a Redis service and set dependencies appropriately. Below, we'll break down the necessary changes.

1. Update Your Docker Compose File

Here’s how you can adjust your docker-compose.yml file to include the Redis server:

2. Breakdown of Changes

Adding the Redis Service:

Under the services section, we added a new service named redis-server. This service uses the redis:alpine Docker image, which is a compact version of the Redis server.

Command to Run Redis:

The command redis-server tells Docker how to run the Redis service.

Specify the Ports:

We've mapped the default Redis port 6379 so that it can be accessed externally. This is important if your application requires connecting to Redis.

Setting Dependencies:

The depends_on configuration ensures that the api service will wait for the redis-server to be fully running before it tries to start the application server.

3. Bringing It All Together

With these modifications, starting your services is as simple as running:

This command will build the required containers and automatically start both your application and the Redis server in the correct order.

Conclusion

Incorporating a Redis server into your Docker setup doesn't need to be a complex task. By modifying your docker-compose.yml file to include a Redis service, you can streamline your development process significantly. This way, your Redis server is ready to go as soon as you start your application server, allowing you to focus on building rather than managing your services.

With these adjustments, productivity increases as you eliminate unnecessary steps. Now you can get back to what really matters — developing your application with ease!
