Its man page is available [here](/docs/user-guide/kubectl/kubectl_port-forward). Compared to [kubectl proxy](/docs/user-guide/accessing-the-cluster/#using-kubectl-proxy), `kubectl port-forward` is more generic as it can forward TCP traffic while `kubectl proxy` can only forward HTTP traffic. This guide demonstrates how to use `kubectl port-forward` to connect to a Redis database, which may be useful for database debugging. ## Creating a Redis master ```shell $ kubectl create -f examples/redis/redis-master.yaml pods/redis-master ``` wait until the Redis master pod is Running and Ready, ```shell $ kubectl get pods NAME READY STATUS RESTARTS AGE redis-master 2/2 Running 0 41s ``` ## Connecting to the Redis master[a] The Redis master is listening on port 6379, to verify this, ```shell{% raw %} $ kubectl get pods redis-master --template='{{(index (index .spec.containers 0).ports 0).containerPort}}{{"\n"}}' 6379{% endraw %} ``` then we forward the port 6379 on the local workstation to the port 6379 of pod redis-master, ```shell $ kubectl port-forward redis-master 6379:6379 I0710 14:43:38.274550 3655 portforward.go:225] Forwarding from 127.0.0.1:6379 -> 6379 I0710 14:43:38.274797 3655 portforward.go:225] Forwarding from [::1]:6379 -> 6379 ``` To verify the connection is successful, we run a redis-cli on the local workstation, ```shell $ redis-cli 127.0.0.1:6379> ping PONG ``` Now one can debug the database from the local workstation.
