I don't think that doing a recursive run on all of pulp_storage_path on every deploy run is a good idea, as with increasing amount of data in there, this will take longer and longer.

Do we need this? Shouldn't the permissions be correct in the backup already?

Guess that's the problem. When restoring a backup files are correctly extracted as root:root. But the new container runs as UID 700 and can't access them.
So now I've made it conditional and it only runs when files are owned by UID 0 (from old root-based backups). If they're already UID 700, it skips entirely.

I think what @evgeni thinks it that since there is no major release based on foremanctl yet, this patch fixes the permissions, therefore all production backups will be all fine.
We can probably do a followup and drop this.

Failing CI is caused by the changes in this PR. @arvind4501 I remember you had a presentation on how to tackle the issue, proposing several strategies how to resolve the issue. If I remember correctly, changing the chmod to I had the same issue in my TFTP feature, where there was a collision between permissions for the quadlet and the services running inside it. See #533 (comment) |
I think since pulp runs as but having said that we also need think about the migration path for 3.19 containers(which runs as root), as |

Yes that's a criticial I see, the host |
So the the TFTP collision you referenced was about choosing an already-system-allocated UID. UID 700 is in the system range and is already reserved by upstream Pulp, so there's no collision risk I believe, correct me if I'm pointing wrong here. Umm so is there a specific concern with 700, or would you recommend a different approach we can look for? |

Ansible ansible.builtin.file module recurse owner group directory existing contents official documentation
💡 Result:
The ansible.builtin.file module allows you to recursively set ownership and permissions on directory contents by using the recurse option [1][2]. According to the official Ansible documentation, the recurse parameter is a boolean that, when set to true, recursively applies the specified file attributes (such as owner and group) to all contents within a directory [1][3]. This parameter is only effective when the state is set to directory [1][4]. When recurse: yes is used, the module acts on the directory itself and all existing files and subdirectories contained within it [1][2]. Example usage from the official documentation: - name: Recursively change ownership of a directory ansible.builtin.file: path: /etc/foo state: directory recurse: yes owner: foo group: foo Important considerations: - The owner and group parameters specify the user and group that should own the filesystem objects [1][2]. - If left unspecified, the module uses the current user's group or ownership (unless running as root, where it may preserve existing ownership) [1][2]. - The module documentation explicitly warns against using purely numeric usernames or group names, as these are interpreted as UIDs and GIDs, which can lead to configuration errors [1][3].

official Pulp container image UID 700 pulp user documentation
💡 Result:
In official Pulp project container images, the pulp user is configured with UID 700 and GID 700 [1][2]. This configuration is explicitly defined in the official container build definitions (Containerfiles), where the user and group are created as system entities [1][2]: RUN groupadd -g 700 --system pulp RUN useradd -d /var/lib/pulp --system -u 700 -g pulp pulp When deploying Pulp using OCI-compliant container images—such as those found in the official pulp/pulp repository—administrators often need to ensure that host-mounted volumes (e.g., for persistent storage) are properly owned by UID 700 to prevent permission errors [3]. For example, when setting up storage directories for Pulp, it is common practice to perform an ownership change to match this UID [3]: podman unshare chown 700:700../../pulp_storage If you are encountering issues where processes cannot write to storage, verifying that the persistent volume or host directory is writable by UID 700 is a standard troubleshooting step [3][4].

quay.io/foreman/pulp:3.73 runtime UID GID Pulp container user
💡 Result:
The Pulp container images, including the versions provided by Foreman (quay.io/foreman/pulp), run as the 'pulp' user [1][2][3]. Unlike some other Foreman-managed containers that have standardized on static UIDs (such as the 'foreman' user at 994 and 'foreman-proxy' at 991) [4][5], the 'pulp' user inside Pulp container images is typically created dynamically during the image build process [6]. Consequently, the numeric UID and GID for the 'pulp' user are not globally fixed and can vary depending on the specific build environment and base OS layer [6]. To determine the exact UID and GID for a specific instance of the image you are running, you can inspect the user within the container using the following command: podman run --rm quay.io/foreman/pulp:3.73 id -u pulp podman run --rm quay.io/foreman/pulp:3.73 id -g pulp Because the UID/GID may be non-deterministic across different builds, administrators managing persistent volume mounts (e.g., /var/lib/pulp) often use mechanisms such as 'podman' volume Z/z flags or explicit 'chown' operations in orchestration scripts to ensure the runtime container user has the necessary permissions to access host-mounted storage [3][7].

site:github.com/theforeman/foreman-oci-images pulp 3.73 UID 700
💡 Result:
There is no widely recognized software or technical standard identified as "Pulp 3.73" associated with a "UID 700." Research into the specific string "pulp 3.73 UID 700" within the context of recent technical developments (as of August 2026) points to the Foreman project's OCI container image ecosystem, specifically within the repository theforeman/foreman-oci-images [1][2]. In July 2026, this project implemented changes to enforce static User IDs (UIDs) and Group IDs (GIDs) for its service users, specifically assigning UID/GID 994 to the "foreman" user and 991 to the "foreman-proxy" user [1][3][4]. It is possible that "Pulp 3.73" refers to a specific version of the Pulp Project (a platform for managing software repositories) or a related component, but there is no direct evidence linking such a version to a UID of 700. In many Linux distributions and container environments, UID 700 is a standard, unprivileged user ID that may be dynamically or statically assigned to various service accounts depending on the specific installation or container configuration. If you are encountering a UID 700 error in relation to Pulp, it likely pertains to local permissions, volume mount constraints, or specific security policies within your container orchestrator (e.g., Podman or Kubernetes) rather than a global identifier for a "Pulp 3.73" release [1][5].

Apply one recursive ownership invariant to Pulp content. The deployment tasks change only the listed directories. Existing descendants keep their ownership. The restore task recurses only when media.stat.uid == 0; a UID-700 media directory can contain root-owned descendants and skip correction. Add a targeted descendant migration during deployment and detect root-owned descendants before skipping the restore correction.

By recreating you mean backup and restore? if not then we may end up lossing all content data and only have a empty directory. IMO a migration task from root to non-root could simply be something like, check if the host dir(/var/lib/pulp) is owned by root, if yes then chown the whole dir recursively(as part of foremanctl deploy), this would be one time only. else run the deployment normally so that upcoming version migrations (from 5.1 container to 5.2 containers, which both have non root UID) does not trigger chowning the dirs as they are alredy owned by non root. |

Set ownership of Pulp storage directories to UID 700 to support the non-root Pulp container image. This ensures the container running as UID 700 can write to bind-mounted volumes. Fixes: SAT-47249

There was a problem hiding this comment.
Instead of hardcoding 700, these could be defaults of the pulp role.:
pulp_container_uid: 700
pulp_container_gid: 700
