I'm having a Redis cluster on Kubernetes.
I need to interact with one of the redis-client pods, mainly in order to delete keys from time to time.
The way I'm currently doing it is:
Tunnel Kubernetes dashobard to localhost:8081
From the dashboard, doing exec into redis client pod
Running: redis-cli -h redis-master -a mypassword
Deleting the needed key, del "*my_key_name*"
I want to be able to do so from a local python script. Using kubernetes for python I'm able to execute commands on redis-client pod:
v1=client.CoreV1Api()
exec_command = [
'/bin/sh',
'-c',
'redis-cli -h redis-master -a mypassword']
resp = stream(v1.connect_get_namespaced_pod_exec,"redis-client2-5889976c9b-nv99v", 'default',
command=exec_command,
stderr=True, stdin=False,
stdout=True, tty=False)My problem is, I can't execute commands in the context of redis-cli, i.e, I can connect to redis-cli but can't send commands to it (only to /bin/sh)
Is there a way to do what I want?
Thanks
Ok so the apparently the solution is pretty simple, I can pass parameters to the redis-cli tool to execute what I want, all in one command. so I did:
exec_command = [
'/bin/sh',
'-c',
'redis-cli -h redis-master -a mypassword del *my_key_name*']and that is it
