This is just a quick note on how to run Redis as a container using Podman on Ubuntu 22.04 (i.e. there will be no mention about SELinux.) Create a persistent volume for the Redis container I like storing all data/volume for containers under /srv/data. So I’ll create a sub-directory called redis-data under the same location. # mkdir -p /srv/data/redis-data Pull the Redis image # podman pull docker.io/redis Create and run the Redis container # podman run -d --name redis_server \ -v /srv/data/redis-data:/var/redis/data \ -p 6379:6379 redis Create systemd service for the Redis container I like creating a systemd service to enable/start the container. ...
