Host and Consume a Repository

This section assumes that you have a repository with content in it. To do this, see the Synchronize a Repository documentation.

Create a Distribution to Serve a Repository Version

Container Distributions can be used to serve the Container registry API containing the content in a repository’s latest version or a specified repository version.

#!/usr/bin/env bash

DIST_NAME=$(head /dev/urandom | tr -dc a-z | head -c5)

# Distributions are created asynchronously.
echo "Creating distribution \
  (name=$DIST_NAME, base_path=$DIST_BASE_PATH repository=$REPO_HREF)."
TASK_HREF=$(http POST $BASE_ADDR/pulp/api/v3/distributions/container/container/ \
  name=$DIST_NAME \
  base_path=$DIST_BASE_PATH \
  repository=$REPO_HREF | jq -r '.task')

# Poll the task (here we use a function defined in docs/_scripts/
wait_until_task_finished $BASE_ADDR$TASK_HREF

echo "Setting DISTRIBUTION_HREF from the completed task."
# DISTRIBUTION_HREF is the pulp-api HREF, not the content app href
DISTRIBUTION_HREF=$(http $BASE_ADDR$TASK_HREF | jq -r '.created_resources | first')

echo "Inspecting Distribution."

Reference: Container Distribution Usage

Pull and Run an Image from Pulp

Once a distribution is configured to host a repository with Container images in it, that content can be consumed by container clients.


An administrator is expected to configure the environment in advance to enable users to consume content with authorized access. Otherwise, the registry will not be able to serve the requested content flawlessly. In Pulp, the token authentication is enabled by default and does not come pre-configured out of the box. Lean more at Authentication.


$ podman pull localhost:24817/test:<tag_name>

If SSL has not been setup for your Pulp, configure podman to work with the insecure registry:

Edit the file /etc/containers/registries.conf. and add:

registries = ['localhost:24817']

More info:


If SSL has not been setup for your Pulp, configure docker to work with the insecure registry:

Edit the file /etc/docker/daemon.json and add:

    "insecure-registries" : ["localhost:24817"]


More info:

#!/usr/bin/env bash


echo "Setting REGISTRY_PATH, which can be used directly with the Docker Client."
REGISTRY_PATH=$(http $BASE_ADDR$DISTRIBUTION_HREF | jq -r '.registry_path')

echo "Next we pull and run the image from pulp"
sudo docker login -u admin -p password $REGISTRY_PATH

Docker Output:

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

When using a container client that cannot handle requested manifests in the new format (schema 2), the manifests are rewritten into the old format (schema 1) on-the-fly by Pulp. In general, the automatic conversion cannot be performed when the content is not available in the storage. Therefore, it may be successful only if the content was previously synced with the immediate policy.
