Valkey Cluster
Stack
Horizontally-scaled Valkey where the keyspace is partitioned across multiple master shards, each with a replica - the same design as Redis Cluster, BSD-licensed and Redis-protocol compatible.

Or deploy it directly from the source:
git clone https://github.com/deployable-sh/stacks
cd stacks
docker compose -f valkey-cluster/compose.yaml up -dMore install options in our documentation.
Check the logs first
Nine times out of ten the logs tell you exactly what went wrong.
- In Portainer, go to Containers, click the container, then Logs. Or run
docker logs <container> - Exit codes help too:
137means killed, usually out of memory.126or127means the command inside the image is broken.
Container keeps restarting
The unless-stopped restart policy relaunches the app after every crash, so the real error can scroll past.
- Check the logs right after a restart, the last few lines before it died are the useful ones.
- Get the exit code with
docker inspect <container> --format '{{.State.ExitCode}}' - Still stuck? Redeploy once with the restart policy set to
noso the failure stays visible.
Stack won't deploy
Compose stacks fail fast on small mistakes, and Portainer shows the reason just above the editor.
- YAML only accepts spaces for indentation, a single tab breaks the whole file.

A Compose stack
Valkey Cluster is a Compose stack, a set of containers (7 of them) defined in one file and brought up together by Portainer, then started and stopped as a single app.
The services
This stack is built from 7 containers that run side by side. Here's each one, with the image it runs and anything it waits for first:
valkey-node-1valkey-node-2valkey-node-3valkey-node-4valkey-node-5valkey-node-6valkey-init, starts after valkey-node-1, valkey-node-2, valkey-node-3, valkey-node-4, valkey-node-5, valkey-node-6
Volumes
A volume is where Valkey Cluster keeps its files so they survive an update or a restart. Without one, anything it saves would sit inside the container and vanish the moment it's recreated. This template mounts:
/datakept in thenode1-datavolume Docker manages/datakept in thenode2-datavolume Docker manages/datakept in thenode3-datavolume Docker manages/datakept in thenode4-datavolume Docker manages/datakept in thenode5-datavolume Docker manages/datakept in thenode6-datavolume Docker manages
Environment variables
Environment variables are the settings you hand over when you deploy, things like a password or a timezone. Valkey Cluster takes 4 of them, all with defaults you can leave alone or tweak:
VALKEY_ROLE, defaults toinitVALKEY_PASSWORD, pulled from your own environmentVALKEY_ANNOUNCE_HOST, defaults tovalkey-node-6CLUSTER_NODES, defaults tovalkey-node-1:6379 valkey-node-2:6379 valkey-node-3:6379 valkey-node-4:6379 valkey-node-5:6379 valkey-node-6:6379
Restart policy
The restart policy here is unless-stopped, so Docker restarts Valkey Cluster after a crash or reboot, but leaves it off when you stop it on purpose. You can change this on the deploy screen. The choices are no (never restart), on-failure (only after a crash), unless-stopped (restart unless you stop it), and always (bring it back no matter what).
Networking
Portainer puts these services on one shared private network, so they can find each other by name (like valkey-node-1) while only the ports above are open to you.
Platform
The platform is linux, the kind of system the container is built to run on. Docker and Portainer handle this on a normal Linux server.
Portainer app templates
Zooming out, this whole page comes from a Portainer app template: a short recipe telling Portainer how to set Valkey Cluster up. Add the template list to Portainer once, then deploying Valkey Cluster is a click rather than a wall of config.
