Developing or Testing
When developing or testing your application, you might not want or can not use Upstash over the internet. In this case, you can use a community project called Serverless Redis HTTP (SRH) created by Scott Hiett.
SRH is a Redis proxy and connection pooler that uses HTTP rather than the Redis binary protocol. The aim of this project is to be entirely compatible with Upstash, and work with any Upstash supported Redis version.
We are working with Scott together to keep SRH up to date with the latest Upstash features.
Use cases for SRH:
- For usage in your CI pipelines, creating Upstash databases is tedious, or you
have lots of parallel runs.
- See Using in GitHub Actions on how to quickly get SRH setup for this context.
- For usage inside of Kubernetes, or any network whereby the Redis server is not
exposed to the internet.
- See Using in Docker Compose for the various setup options directly using the Docker Container.
- For local development environments, where you have a local Redis server running, or require offline access.
Setting up SRH
Via Docker command
If you have a locally running Redis server, you can simply start an SRH
container that connects to it. In this example, SRH will be running on port
8080
.
Via Docker Compose
If you wish to run in Kubernetes, this should contain all the basics would need to set that up. However, be sure to read the Configuration Options, because you can create a setup whereby multiple Redis servers are proxied.
In GitHub Actions
SRH works nicely in GitHub Actions because you can run it as a container in a job’s services. Simply start a Redis server, and then SRH alongside it. You don’t need to worry about a race condition of the Redis instance not being ready, because SRH doesn’t create a Redis connection until the first command comes in.
A huge thanks goes out to Scott for creating this project, and for his continued efforts to keep it up to date with Upstash.
