Question

How to use memcached in the app platform?

I am trying to figure out the best alternative to use some sort of memory caching for a Django application with a postgress database deployed on DigitalOcean App Platform.

I cannot see any documentation of how to include memcached or any other in-memory management tool as part of the App Platform deployment.

Any Ideas will be appreciated

Hi @mariorossell Memcached is an in-memory data storage system. You can run Memcached as an internal service in the App Platform. It is an internal service therefore there will be no HTTP route or PORT set.

A sample code for a Memcached service can be seen like below

Sample Code for Memcached internal service
- name: library-memcached
  image:
    registry: library
    registry_type: DOCKER_HUB
    repository: memcached
    tag: latest
  instance_count: 1
  instance_size_slug: basic-xs
  internal_ports:
    - 11211

Other services can access the Memcached service using <servicename>:<internal_ports> like below for the above sample Memcached service.

  1. library-memcached:11211

After successful deployment, to connect other services with Memcached service, run the below command in the service console from whom you want to connect Memcached with.

  1. telnet library-memcached 11211

Note: App Platform instances are ephemeral and can be redeployed at any time which would cause the contents of the Memcached server to be lost.

Other than Memcached for in-memory data storage, we also provide Redis as a managed database in the Digital Ocean. You can view the below links for information related to how to create Redis Database and how to manage databases in the App Platfrom.

I’m a little late to reply, but for posterity, the MemCachier Add-On from the DigitalOcean Marketplace is now available, enabling you to provision a Memcached-compliant cache for your App Platform app with one click.
