Users need to have access to the cluster to view its pods and its data.
Shows you the configuration of the selected pod and allows you to edit it. Refer Edit Manifest to learn more.
Shows you all the activities (create/update/delete) of the selected pod. Refer View Events to know more.
Examining your cluster's pods helps you understand the health of your application. By inspecting pod logs, you can check the performance and identify if there are any failures. This is especially useful for debugging any issues effectively.
Moreover, you can download the pod logs for ease of sharing and troubleshooting as shown in the below video.
Frequent pod restarts can impact your application as it might lead to unexpected downtimes. In such cases, it is important to determine the root cause and take actions (both preventive and corrective) if needed.
In case any of your pod restarts, you can view its details from the pod listing screen:
Last pod restart event, along with the timestamp and message
Reason behind restart
Container log before restart
Node status and events
User needs to be an admin of the Kubernetes resource to access pod terminal.
You can access the terminal within a running container of a pod to view its logs, troubleshoot issues, or execute commands directly. This is different from the cluster terminal you get at node level.
This is a part of Pod Terminal. It is especially useful when kubectl exec is insufficient because a container has crashed or a container image doesn't include debugging utilities.
In the Resource Browser, select Pod within Workloads.
Use the searchbar to find and locate the pod you wish to debug. Click the pod.
Go to the Terminal tab
Click Launch Ephemeral Container as shown below.
You get 2 tabs:
Basic - It provides the bare minimum configurations required to launch an ephemeral container.
It contains 3 mandatory fields:
Container name prefix - Type a prefix to give to your ephemeral container, for e.g., debug. Your container name would look like debug-jndvs.
Image - Choose an image to run from the dropdown. Ephemeral containers need an image to run and provide the capability to debug, such as curl. You can use a custom image too.
Target Container name - Since a pod can have one or more containers, choose a target container you wish to debug, from the dropdown.
Advanced - It is particularly useful for advanced users that wish to use labels or annotations since it provides additional key-value options. Refer Ephemeral Container Spec to view the supported options.
