| Concept |
A concept page explains some aspect of Kubernetes. For example, a concept page might describe the Kubernetes Deployment object and explain the role it plays as an application while it is deployed, scaled, and updated. Typically, concept pages don't include sequences of steps, but instead provide links to tasks or tutorials. For an example of a concept topic, see Nodes. |
| Task |
A task page shows how to do a single thing. The idea is to give readers a sequence of steps that they can actually do as they read the page. A task page can be short or long, provided it stays focused on one area. In a task page, it is OK to blend brief explanations with the steps to be performed, but if you need to provide a lengthy explanation, you should do that in a concept topic. Related task and concept topics should link to each other. For an example of a short task page, see Configure a Pod to Use a Volume for Storage. For an example of a longer task page, see Configure Liveness and Readiness Probes |
| Tutorial |
A tutorial page shows how to accomplish a goal that ties together several Kubernetes features. A tutorial might provide several sequences of steps that readers can actually do as they read the page. Or it might provide explanations of related pieces of code. For example, a tutorial could provide a walkthrough of a code sample. A tutorial can include brief explanations of the Kubernetes features that are being tied together, but should link to related concept topics for deep explanations of individual features. |
Use a template for each new page. Each page type has a
[template](/docs/contribute/style/page-templates/)
that you can use as you write your topic. Using templates helps ensure
consistency among topics of a given type.
## Choosing a title and filename
Choose a title that has the keywords you want search engines to find.
Create a filename that uses the words in your title separated by hyphens.
For example, the topic with title
[Using an HTTP Proxy to Access the Kubernetes API](/docs/tasks/access-kubernetes-api/http-proxy-access-api/)
has filename `http-proxy-access-api.md`. You don't need to put
"kubernetes" in the filename, because "kubernetes" is already in the
URL for the topic, for example:
http://kubernetes.io/docs/tasks/access-kubernetes-api/http-proxy-access-api/
## Adding the topic title to the front matter
In your topic, put a `title` field in the
[front matter](https://jekyllrb.com/docs/frontmatter/).
The front matter is the YAML block that is between the
triple-dashed lines at the top of the page. Here's an example:
---
title: Using an HTTP Proxy to Access the Kubernetes API
---
## Choosing a directory
Depending on your page type, put your new file in a subdirectory of one of these:
* /content/en/docs/tasks/
* /content/en/docs/tutorials/
* /content/en/docs/concepts/
You can put your file in an existing subdirectory, or you can create a new
subdirectory.
## Placing your topic in the table of contents
The table of contents is built dynamicaly using the directory structure of the
documentation source. The top-level directories under `/content/en/docs/` create
top-level navigation, and subdirectories each have entries in the table of
contents.
Each subdirectory has a file `_index.md`, which represents the "home" page for
a given subdirectory's content. The `_index.md` does not need a template. It
can contain overview content about the topics in the subdirectory.
Other files in a directory are sorted alphabetically by default. This is almost
never the best order. To control the relative sorting of topics in a
subdirectory, set the `weight:` front-matter key to an integer. Typically, we
use multiples of 10, to account for adding topics later. For instance, a topic
with weight `10` will come before one with weight `20`.
## Embedding code in your topic
If you want to include some code in your topic, you can embed the code in your
file directly using the markdown code block syntax. This is recommended for the
following cases (not an exhaustive list):
- The code shows the output from a command such as
`kubectl get deploy mydeployment -o json | jq '.status'`.
- The code is not generic enough for users to try out. As an example, you can
embed the YAML
file for creating a Pod which depends on a specific
[Flexvolume](/docs/concepts/storage/volumes#flexvolume) implementation.
- The code is an incomplete example because its purpose is to highlight a
portion of a larger file. For example, when describing ways to
customize the [PodSecurityPolicy](/docs/tasks/administer-cluster/sysctl-cluster/#podsecuritypolicy)
for some reasons, you can provide a short snippet directly in your topic file.
- The code is not meant for users to try out due to other reasons. For example,
when describing how a new attribute should be added to a resource using the
`kubectl edit` command, you can provide a short example that includes only
the attribute to add.
## Including code from another file
Another way to include code in your topic is to create a new, complete sample
file (or group of sample files) and then reference the sample from your topic.
Use this method to include sample YAML files when the sample is generic and
reusable, and you want the reader to try it out themselves.
When adding a new standalone sample file, such as a YAML file, place the code in
one of the `
