The command kubectl gel pods --all-namespaces -l 'env in (development)' does not display all the pods in the cluster that are labeled as env: development. The command has two typos that prevent it from working correctly. First, the verb should be get instead of gel. Second, the label selector flag should be -l instead of -I1. The correct command should be kubectl get pods --all-namespaces -l 'env in (development)', which will list all the pods across all namespaces that have a label env with a value development2.

To configure a Docker container to export container logs to a logging solution such as Splunk, you need to set the log-driver and log-opt keys to values for the logging solution in the daemon.json file. This will enable the Splunk logging driver, which sends container logs to HTTP Event Collector in Splunk Enterprise and Splunk Cloud1. You can also use the command-line flags --log-driver and --log-opt with docker run to use the Splunk driver for a specific container1. References:

Explanation
= The command docker logs <container-id> will not configure a Docker container to export container logs to the logging solution, such as Splunk. This command only displays the logs of a specific container in the standard output or a file, but does not send them to any external system1. To export container logs to Splunk, you need to use the Docker Logger Drivers, which are plugins that provide logging capabilities for Dockercontainers2. The Splunk logging driver sends container logs to HTTP Event Collector in Splunk Enterprise and Splunk Cloud3. To use the Splunk logging driver for a specific container, you need to use the command-line flags --log-driver and --log-opt with docker run, and provide the Splunk token and URL as options3. For example:
$ docker run --log-driver=splunk --log-opt splunk-token=VALUE --log-opt splunk-url=VALUE ...

Explanation
This command does display all the pods in the cluster that are labeled as env: development. The kubectl get pods command shows information about all the pods in a cluster or a specific namespace. The
--all-namespaces flag tells kubectl to include pods from all namespaces in the output. The -l flag tells kubectl to filter the output by a label selector, which is an expression that matches labels to values. The label selector
'env in (development)' matches pods that have a label env with a value development. Therefore, this command displays all the pods in the cluster that are labeled as env: development. References:
