# Container Registry
Publish [Open Container Initiative](https://opencontainers.org/) compliant images for your user or organization.
The container registry follows the OCI specs and supports all compatible images like [Docker](https://www.docker.com/) and [Helm Charts](https://helm.sh/).
**Table of Contents**

## Requirements
To work with the Container registry, you can use the tools for your specific image type.
The following examples use the `docker` client.
## Login to the container registry
To push an image or if the image is in a private registry, you have to authenticate:
```shell
docker login gitea.example.com
```
## Image naming convention
Images must follow this naming convention:
`{registry}/{owner}/{image}`
For example, these are all valid image names for the owner `testuser`:
`gitea.example.com/testuser/myimage`
`gitea.example.com/testuser/my-image`
`gitea.example.com/testuser/my/image`
**NOTE:** The registry only supports case-insensitive tag names. So `image:tag` and `image:Tag` get treated as the same image and tag.
## Push an image
Push an image by executing the following command:
```shell
docker push gitea.example.com/{owner}/{image}:{tag}
```
| Parameter | Description |
| ----------| ----------- |
| `owner` | The owner of the image. |
| `image` | The name of the image. |
| `tag` | The tag of the image. |
For example:
```shell
docker push gitea.example.com/testuser/myimage:latest
```
## Pull an image
Pull an image by executing the following command:
```shell
docker pull gitea.example.com/{owner}/{image}:{tag}
```
| Parameter | Description |
| ----------| ----------- |
| `owner` | The owner of the image. |
| `image` | The name of the image. |
| `tag` | The tag of the image. |
For example:
```shell
docker pull gitea.example.com/testuser/myimage:latest
```
