No output from elasticsearch curator!
I installed Elasticsearch Curator 5.6 to help manage Elasticsearch indexes. I used the RPM to install on a CentOS 6 docker container and although the yum install was successful. I found that there was no output from curator when executed in command line. After some googling found this ticket: https://github.com/elastic/curator/issues/1243 In summary you need to set the LC_ALL environment variable to a valid value to fix it. #ELK, #curator
