# Kubernetes Logs
2019-07-31 22:56:46 +05:30
2020-06-23 00:09:42 +05:30
> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/4752) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 11.0.
2020-05-24 23:13:21 +05:30
> - [Moved](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26383) to [GitLab Core](https://about.gitlab.com/pricing/) 12.9.
2019-07-31 22:56:46 +05:30
GitLab makes it easy to view the logs of running pods in [connected Kubernetes clusters](index.md).
2020-05-24 23:13:21 +05:30
By displaying the logs directly in GitLab in the **Log Explorer**, developers can avoid
managing console tools or jumping to a different interface.
2019-10-12 21:52:04 +05:30
NOTE: **Kubernetes + GitLab**
2020-05-24 23:13:21 +05:30
Everything you need to build, test, deploy, and run your application at scale.

## Overview
2020-05-24 23:13:21 +05:30
[Kubernetes](https://kubernetes.io) logs can be viewed directly within GitLab with
the **Log Explorer**.

## Requirements
2020-05-24 23:13:21 +05:30
[Deploying to a Kubernetes environment](../deploy_boards.md#enabling-deploy-boards)
is required to use Logs.
2019-12-26 22:10:19 +05:30
## Usage
2020-04-08 14:13:33 +05:30
To access logs, you must have the right [permissions](../../permissions.md#project-members-permissions).
2019-12-26 22:10:19 +05:30
You can access them in two ways.
### From the project sidebar
2020-03-13 15:44:24 +05:30
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/22011) in GitLab 12.5.
2019-12-26 22:10:19 +05:30
2020-05-24 23:13:21 +05:30
Go to **{cloud-gear}** **Operations > Pod logs** on the sidebar menu to display
the **Log Explorer**.

![Sidebar menu](img/sidebar_menu_pod_logs_v12_10.png)
2019-12-26 22:10:19 +05:30
### From Deploy Boards
Logs can be displayed by clicking on a specific pod from [Deploy Boards](../deploy_boards.md):
2019-07-31 22:56:46 +05:30
2020-05-24 23:13:21 +05:30
1. Go to **{cloud-gear}** **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](../deploy_boards.md).
1. When mousing over the list of pods, a tooltip will appear with the exact pod name
and status.

### Logs view
2020-05-24 23:13:21 +05:30
The **Log Explorer** lets you filter the logs by:
2020-03-13 15:44:24 +05:30
- Pods.
2020-06-23 00:09:42 +05:30
- [From GitLab 12.4](https://gitlab.com/gitlab-org/gitlab/-/issues/5769), environments.
2020-05-24 23:13:21 +05:30
- [From GitLab 12.7](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/21656),
[full text search](#full-text-search).
2020-06-23 00:09:42 +05:30
- [From GitLab 12.8](https://gitlab.com/gitlab-org/gitlab/-/issues/197879), dates.
2020-03-13 15:44:24 +05:30
2020-05-24 23:13:21 +05:30
Loading more than 500 log lines is possible from
[GitLab 12.9](https://gitlab.com/gitlab-org/gitlab/-/issues/198050) onward.
2020-04-08 14:13:33 +05:30
2020-05-24 23:13:21 +05:30
Support for pods with multiple containers is coming
2020-06-23 00:09:42 +05:30
[in a future release](https://gitlab.com/gitlab-org/gitlab/-/issues/13404).

2020-03-13 15:44:24 +05:30
### Filter by date
2020-06-23 00:09:42 +05:30
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/197879) in GitLab 12.8.

2020-05-24 23:13:21 +05:30
When you enable [Elastic Stack](../../clusters/applications.md#elastic-stack)
on your cluster, you can filter logs displayed in the **Log Explorer** by date.
2020-03-13 15:44:24 +05:30
2020-05-24 23:13:21 +05:30

When you enable [Elastic Stack](../../clusters/applications.md#elastic-stack) on your cluster,
2020-04-08 14:13:33 +05:30
you can search the content of your logs through a search bar.
2020-03-13 15:44:24 +05:30
2020-05-24 23:13:21 +05:30
The search is passed on to Elasticsearch using the
[simple_query_string](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-simple-query-string-query.html)
2020-03-13 15:44:24 +05:30
Elasticsearch function, which supports the following operators:
| Operator | Description |
|----------------------------|------------------------------------------------------------|
| `\|` | An OR operation. |
| `-` | Negates a single token. |
| `+` | An AND operation. |
| `"` | Wraps a number of tokens to signify a phrase for searching. |
| `*` (at the end of a term) | A prefix query. |
| `(` and `)` | Precedence. |
| `~N` (after a word) | Edit distance (fuzziness). |
| `~N` (after a phrase) | Slop amount. |
