Ticket

Changes

Image platform overrides (PR , JIRA Ticket)

• Documents the new os, arch, and variant task config fields that override the platform used when pulling an image (mirroring podman's --os, --arch, --variant flags)
• Adds an example and explains the always-pull behavior when any override is set, plus constraint guidance for pinning workloads to compatible nodes

IPC namespace mode (PR , JIRA Ticket)

• Documents the new ipc_mode task config with all supported values (host, private, shareable, none, container:, ns:, task:)
• Adds a task:mps-daemon example and the shm_size compatibility note

Custom Podman network names (PR , JIRA Ticket)

• Documents that network_mode accepts the name of a pre-existing Podman network created with podman network create
• Notes the network must already exist and that this requires Podman 4.0 or later; adds a network_mode = "mynet" example

HTTP(S) archive URLs for images (PR , JIRA Ticket)

• Documents that the image field's oci-archive and docker-archive transports accept http(s):// URLs, not just local archive paths
• Adds an oci-archive:https://... example
