1. Enter workshop dir $ cd chapter01-basic-knowledges/1.4-basic-redis/01-run-redis

2. Create k8s namespace $ kubectl apply -f 00-namespace.yml namespace/basic-redis created

3. Check if namespace has created $ kubectl get ns NAME STATUS AGE basic-redis Active 20s default Active 7h59m ingress-nginx Active 46m kube-node-lease Active 7h59m kube-public Active 7h59m kube-system Active 7h59m

4. Create redis deployment $ kubectl apply -f 01-deployment.yml deployment.apps/redis created

5. Check redis deployment has created $ kubectl get po -n basic-redis NAME READY STATUS RESTARTS AGE redis-577d58dd6c-g7brv 0/1 Running 0 26s

** Wait until the STATUS is Running

6. Create redis service $ kubectl apply -f 02-service.yml service/redis created

7. Check redis service has created $ kubectl get svc -n basic-redis NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE redis ClusterIP None 6379/TCP 19s

8. Create client-util pod $ kubectl apply -f 03-client-util.yml pod/client-util created

9. Check if client-util pod has created $ kubectl get po -n basic-redis NAME READY STATUS RESTARTS AGE client-util 1/1 Running 0 96s redis-577d58dd6c-g7brv 1/1 Running 0 3m54s

** Wait until the STATUS is Running

10. Exec into client-util pod $ kubectl exec -it client-util -n basic-redis -- bash root@client-util:/#

11. Run redis-cli to connect to redis $ redis-cli -h redis redis:6379>

12. Exit from redis-cli $ exit root@client-util:/#

12.1 test $ SET "name" "rachata" $ GET name

13. Exit from client-util

14. Do not cleanup workshop, we will use it in next workshop

1. Exec into client-util pod $ kubectl exec -it client-util -n basic-redis -- bash

2. Start redis-cli $ redis-cli -h redis redis:6379>

3. Use SET command to set mykey = myvalue $ SET "mykey" "myvalue" OK

4. Use GET to get value from key $ GET "mykey" "myvalue"

5. Use EXPIRE command to expire mykey in 10 seconds $ EXPIRE "mykey" 10 (integer) 1

** Wait 10 seconds

6. Test get mykey when it is expired $ GET "mykey" (nil)

7. SET mykey2 $ SET "mykey2" "myvalue2" OK

8. GET mykey2 $ GET "mykey2" "myvalue2"

9. Use DEL command to delete mykey2 $ DEL "mykey2" (integer) 1

10. GET mykey2 to see how it is deleted $ GET "mykey2" (nil)

11. SET mykey1 and mykey2 $ SET "mykey1" "value1" $ SET "mykey2" "value2"

12. Use KEYS to list all keys using wildcard $ KEYS "mykey*"

1. "mykey2"
2. "mykey1"

13. Exit from redis $ exit

14. Exit from client-util $ exit

15. Cleanup workshop $ kubectl delete ns basic-redis
