GET/v2/registry/docker-credentialsDeprecated

Get Docker Credentials for Container Registry

Note: This endpoint is deprecated. Please use the /v2/registries endpoint instead.

In order to access your container registry with the Docker client or from a Kubernetes cluster, you will need to configure authentication. The necessary JSON configuration can be retrieved by sending a GET request to /v2/registry/docker-credentials.

The response will be in the format of a Docker config.json file. To use the config in your Kubernetes cluster, create a Secret with:

kubectl create secret generic docr \
  --from-file=.dockerconfigjson=config.json \
  --type=kubernetes.io/dockerconfigjson

By default, the returned credentials have read-only access to your registry and cannot be used to push images. This is appropriate for most Kubernetes clusters. To retrieve read/write credentials, suitable for use with the Docker client or in a CI system, read_write may be provided as query parameter. For example: /v2/registry/docker-credentials?read_write=true

By default, the returned credentials will not expire. To retrieve credentials with an expiry set, expiry_seconds may be provided as a query parameter. For example: /v2/registry/docker-credentials?expiry_seconds=3600 will return credentials that expire after one hour.

2 parameters

The duration in seconds that the returned registry credentials will be valid. If not set or 0, the credentials will not expire.
Default:0
read_writebooleanoptional
By default, the registry credentials allow for read-only access. Set this query parameter to `true` to obtain read-write credentials.
