Docker image for find and label the redis pods( sentinel enabled) in the kubernetes cluster according to the role ( master, slave)
A simple python script to find the redis pods in Kubernetes for the given labels and label them according to the rule.
redis-cli -h redis-ha.redis -p 26379 sentinel get-master-addr-by-name mymaster - used to get the redis master service details
grep -E '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' - used to get the IP address filtered
Those pods updated with the labels master, slave accordingly.
