# TIR Container Registry FAQ

## What is the registry address?

`registry.e2enetworks.net` in Delhi, and `in-south1-registry.e2enetworks.net` in Chennai. Your
registry's address is also in its **Docker Commands** panel. See
[Log in to a registry](/tir/tir-container-registry/how-to/log-in-to-a-registry/).

## Which username and password do I use?

Each registry has its own. The **Username** is in **Manage E2E Registries**, and the password is in
the login command in the **Docker Commands** panel. They stay valid for as long as the registry exists. See
[Log in to a registry](/tir/tir-container-registry/how-to/log-in-to-a-registry/).

## What can the username and password do?

They can list, pull, push, and delete images and tags in that registry only. See
[Create a registry](/tir/tir-container-registry/how-to/create-a-registry/).

## How is a registry billed?

Each registry is billed per GB on the peak storage it holds in a calendar month. For the rate, see
[E2E's pricing page](https://www.e2enetworks.com/pricing).

## Is there a storage limit?

No. A new registry holds as many images as you push to it. See [Create a
registry](/tir/tir-container-registry/how-to/create-a-registry/).

## Can I use a registry image from a pipeline?

Yes. The **Docker Commands** panel shows an ImagePullSecret name, `namespace-secret-<registry id>`, to use in
a pipeline or an Argo workflow YAML file. See
[Log in to a registry](/tir/tir-container-registry/how-to/log-in-to-a-registry/).

## How do I run an image from my registry?

Create an Instance from it. See
[Create an Instance from your own image](/tir/tir-instance/how-to/create-an-instance-from-your-own-image/).

## Why did deleting a tag delete other tags?

Tags that name the same content are deleted together. See
[Delete a tag](/tir/tir-container-registry/how-to/delete-a-tag/).

## Why is a delete refused?

An Instance or a Model Endpoint still uses the registry, the image, or the tag. Delete or change it,
then try again. See
[Troubleshooting TIR Container Registry](/tir/tir-container-registry/troubleshooting/tir-container-registry/).

## Can I restore a deleted registry?

No. Deleting a registry removes its images permanently, so copy any image you want to keep
first. See [Delete a registry](/tir/tir-container-registry/how-to/delete-a-registry/).
