Container Registry
Publish Open Container Initiative compliant images for your user or organization.
The container registry follows the OCI specs and supports all compatible images like Docker and Helm Charts.
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:
docker login gitea.example.com
If you are using 2FA or OAuth use a personal access token instead of the password.
Image naming convention
Images must follow this naming convention:
{registry}/{owner}/{image}
When building your docker image, using the naming convention above, this looks like:
# build an image with tag
docker build -t {registry}/{owner}/{image}:{tag} .
# name an existing image with tag
docker tag {some-existing-image}:{tag} {registry}/{owner}/{image}:{tag}
where your registry is the domain of your gitea instance (e.g. gitea.example.com).
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:
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:
docker push gitea.example.com/testuser/myimage:latest
Pull an image
Pull an image by executing the following command:
docker pull gitea.example.com/{owner}/{image}:{tag}
Parameter | Description |
---|---|
owner |
The owner of the image. |
image |
The name of the image. |

The tag of the image. |
For example:
docker pull gitea.example.com/testuser/myimage:latest
