pre-commit

pre-commit is configured for this formula, which you may optionally use to ease the steps involved in submitting your changes. First install the pre-commit package manager using the appropriate method, then run bin/install-hooks and now pre-commit will run automatically on each git commit.

$ bin/install-hooks
pre-commit installed at .git/hooks/pre-commit

Special notes

None.

Todo

• merge redis 2.4 and 2.6 templates to generic redis.conf.jinja

Available states

• redis
• redis.clean
• redis.common
• redis.server
• redis.server.clean
• redis.sentinel

redis

Meta-state (This is a state that includes other states).

This state installs the Redis server solution (see https://redis.io)

redis.clean

Meta-state (This is a state that includes other states).

Stop Redis daemon and remove redis server solution.

redis.common

Install redis only

redis.server

Install redis and start up the service ( Ubuntu + RedHat based systems should work ).

For a list of all available options, look at: redis/files/redis-{version}.conf.jinja - also have a look at the pillar.example and map.jinja.

To use the new redis 3.2 template (more structured) add the following line to the pillar:

source_path: salt://redis/files/redis-3.2-ng.conf.jinja

For options that aren't in the template (timeout, for example in redis-2.8 template), you can use extra_opts:

extra_opts:
  timeout: 10

redis.server.clean

Meta-state (This is a state that includes other states).

Stop Redis daemon and remove redis package/archive.

redis.sentinel

Install redis sentinel. Compatible with Ubuntu 14/16 and CentOS 6/7.

Testing

Linux testing is done with kitchen-salt.

Requirements

• Ruby
• Docker

$ gem install bundler
$ bundle install
$ bin/kitchen test [platform]

Where [platform] is the platform name defined in kitchen.yml, e.g. debian-9-2019-2-py3.

bin/kitchen converge

Creates the docker instance and runs the redis main states, ready for testing.

bin/kitchen verify

Runs the inspec tests on the actual instance.

bin/kitchen destroy

Removes the docker instance.

bin/kitchen test

Runs all of the stages above in one go: i.e. destroy + converge + verify + destroy.

bin/kitchen login

Gives you SSH access to the instance for manual testing.
