It seems that redis changed the default for protected mode so that if you’ve got a separate data container it no longer allows connections. My caveman solution is to add this to data.yml in the hooks section.
after_redis:
- replace:
filename: "/etc/redis/redis.conf"
from: /^protected-mode yes/
to: "protected-mode no"
There’s probably a smarter way to allow only connections from the docker network or some such, so I’ll leave it to someone more clever than I to submit a PR.
EDIT: If you see errors that look like
Failed to report error: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no auth
entication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect
from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no'
then this is the solution.
