Configure the coordination backend about st2-docker HOT 5 CLOSED

Just noting the following.

After adding:

[coordination]
url = redis://redis-pass@redis:6379

to /etc/st2/st2.conf, the WARNING disappears, but I now see the following error in st2notifier.log:

st2notifier.log:  File "/opt/stackstorm/st2/local/lib/python2.7/site-packages/tooz/drivers/redis.py", line 28, in <module>
st2notifier.log:    import redis
st2notifier.log:ImportError: No module named redis

from st2-docker.

See https://docs.stackstorm.com/reference/policies.html

Some of these coordination backends also require corresponding client libraries to be installed in StackStorm virtualenv. We do not ship these libraries by default. As an example, to install the client library in StackStorm virtualenv, run

sudo su
source /opt/stackstorm/st2/bin/activate
pip install redis

from st2-docker.

Is concurrency policy on a StackStorm action tested w/ this new setup?

from st2-docker.

Yes, as of 9c76308. Thanks for the suggestion to test concurrency in more depth than what I'd done previously. The documentation has been improved accordingly.

Does st2.conf file support adding redundant pairs of backend coordinator like zookeeper or redis?
We have zookeeper cluster (3 instances) but not sure how to include 3 instances in st2.conf.
Tried below config but doesn't work.

[coordination]
url = kazoo://user:pass@host1:2181/,
kazoo://user:pass@host2:2181/,
kazoo://user:pass@host3:2181/
