# Applications

In Kubernetes, an application is a collection of configuration settings and variables required to run your app. This may consist of a single container or multiple containers with complex interoperability.

You can filter the list of applications by namespace using the **Namespace** dropdown.

Portainer lets you add applications either using a form or through code (for example a manifest or a Helm chart):

{% content-ref url="/pages/-Mhzk5G-abMCAP5dCvJi" %}
[Add a new application using a form](/sts/user/kubernetes/applications/add.md)
{% endcontent-ref %}

{% content-ref url="/pages/-MhzlDtN\_U8sqWrdcbgN" %}
[Add a new application using code](/sts/user/kubernetes/applications/manifest.md)
{% endcontent-ref %}

You can also inspect a running application:

{% content-ref url="/pages/-MhzmdIMIjnWVFNPjP3H" %}
[Inspect an application](/sts/user/kubernetes/applications/inspect.md)
{% endcontent-ref %}

{% content-ref url="/pages/77LkxX8pWXsCeaWt7WQ1" %}
[Inspect a Helm application](/sts/user/kubernetes/applications/inspect-helm.md)
{% endcontent-ref %}

Applications can be edited, webhooks can be configured and volumes can be detached:

{% content-ref url="/pages/-Mk-Bxbkj4QD44fsaBL5" %}
[Edit an application](/sts/user/kubernetes/applications/edit.md)
{% endcontent-ref %}

{% content-ref url="/pages/c7aPMXH76NMtgapNVN7j" %}
[Edit a Helm application](/sts/user/kubernetes/applications/edit-helm.md)
{% endcontent-ref %}

{% content-ref url="/pages/EmHMYVXbmcRmjYRvAS29" %}
[Webhooks](/sts/user/kubernetes/applications/webhooks.md)
{% endcontent-ref %}

{% content-ref url="/pages/-Mi-TS\_aOaavAAhdFFeP" %}
[Detach a volume from an application](/sts/user/kubernetes/applications/detach-volume.md)
{% endcontent-ref %}

If you no longer require an application, it can be removed:

{% content-ref url="/pages/-MhzmSPy\_bwmUDdnWPz3" %}
[Remove an application](/sts/user/kubernetes/applications/remove.md)
{% endcontent-ref %}
