+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab-ee/issues/4752) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.0.
+
+GitLab makes it easy to view the logs of running pods in [connected Kubernetes clusters](index.md).
+By displaying the logs directly in GitLab, developers can avoid having to manage console tools or jump to a different interface.
+
+## Overview
+
+[Kubernetes](https://kubernetes.io) pod logs can be viewed directly within GitLab. Logs can be displayed by clicking on a specific pod from [Deploy Boards](https://docs.gitlab.com/ee/user/project/deploy_boards.html):
+
+1. Go to **Operations > Environments** and find the environment which contains the desired pod, like `production`.
+1. On the **Environments** page, you should see the status of the environment's pods with [Deploy Boards](https://docs.gitlab.com/ee/user/project/deploy_boards.html).
+1. When mousing over the list of pods, a tooltip will appear with the exact pod name and status.
+![Deploy Boards pod list](img/pod_logs_deploy_board.png)
+1. Click on the desired pod to bring up the logs view, which will contain the last 500 lines for that pod. Support for pods with multiple containers is coming [in a future release](https://gitlab.com/gitlab-org/gitlab-ee/issues/6502).

+## Requirements
+
+[Enabling Deploy Boards](https://docs.gitlab.com/ee/user/project/deploy_boards.html#enabling-deploy-boards) is required in order to be able to use Pod Logs.
