Accessing and Interacting with Pods

To execute commands within containers of a pod, you can access their shell. Here’s how:

kubectl exec -it mynginx -- /bin/sh

This command opens an interactive shell session within the mynginx container. Now, you can run various commands inside the container, such as using curl to interact with web servers.

Alternative: Running Commands without Shell Access

One we run command, we get access to mynginx shell. Any further command will be executed inside this, we can run curl command here.

curl localhost

Similarly, we can try with different urls,

curl https://example.com

Or download a file

curl -O https://example.com/file.zip

Alternatively without directly accessing the shell, we can run commands on our pods.

kubectl exec -it mynginx -- [command-to-run]
kubectl exec -it mynginx -- curl localhost

Ever needed to fetch data or test connectivity from within a Kubernetes pod? The curl command becomes your trusty companion in these situations. This guide explores different approaches to execute curl commands directly from within your Kubernetes pod, empowering you to diagnose issues and interact with external services effectively.
