redis 6.2.1 Failed with result 'protocol' Fixed after adding "supervised auto" to templates/redis.conf.j2

OS VERSION="20.04.2 LTS (Focal Fossa)"

pre_tasks:

• name: Add chris-lea APT repositories apt_repository: repo: "ppa:redislabs/redis" state: present update_cache: yes

as from: https://github.com/redis/redis/blob/unstable/redis.conf#L249-L265 (vs the v5 config: https://github.com/redis/redis/blob/5.0/redis.conf#L138-L147)

There is a need to uncomment (or add an include file via the var: redis_includes, check the Readme with content supervised auto

# If you run Redis from upstart or systemd, Redis can interact with your
# supervision tree. Options:
#   supervised no      - no supervision interaction
#   supervised upstart - signal upstart by putting Redis into SIGSTOP mode
#                        requires "expect stop" in your upstart job config
#   supervised systemd - signal systemd by writing READY=1 to $NOTIFY_SOCKET
#                        on startup, and updating Redis status on a regular
#                        basis.
#   supervised auto    - detect upstart or systemd method based on
#                        UPSTART_JOB or NOTIFY_SOCKET environment variables
# Note: these supervision methods only signal "process is ready."
#       They do not enable continuous pings back to your supervisor.
#
# The default is "no". To run under upstart/systemd, you can simply uncomment
# the line below:
#
# supervised auto

Can we reopen this? I was just bitten by this :/

Same issue, any workaround ?

[smutel]

As a workaround:

daemonize no
supervised auto

[nicovs]

I do it like this: Setup a host or group var on your redis_servers group

redis_include: |
  supervised auto

Add this to your playbook:

- name: create redis folder
  file:
    path: /etc/redis
    state: directory

- set_fact:
    redis_includes: [ '/etc/redis/redis_include.conf' ]
  when: redis_include is defined

- name: Redis Include extra options
  template: 
    src: "{{ playbook_dir }}/templates/redis/redis_include.conf.j2"
    dest: /etc/redis/redis_include.conf
    owner: redis
    group: redis
    mode: 0640
  notify: 
    - restart redis
  when: redis_include is defined

- import_role:
    name: geerlingguy.redis

and a template in: templates/redis/redis_include.conf.j2

{{ redis_include }}

This should be reopened, it's still a problem with Redis 7.4.1.

An even simpler workaround:

redis_extra_config: |-
  supervised auto
