Two new recipes for the owntone and paperless-ngx apps have been released to the openmediavault-k8s-recipes GitHub repository. You can get them after updating the recipes list in your openmediavault-k8s plugin.

The following list of applications is now available:

• filebrowser
• immich
• jellyfin
• minio
• owntone
• paperless-ngx
• photoprism
• plex-media-server
• wetty

Contributions from the community are welcome to increase the number of recipes.

The recipe editor of the openmediavault-k8s has a DSL (Domain Specific Language) that supports the user in getting specific information from their openmediavault host system in Kubernetes manifests.

The following functions are currently available:

• hostname() – Get the hostname of the host.
• domain() – Get the domain name of the host.
• fqdn() – Get the FQDN of the host.
• ipaddr(name=NULL) – Get the IPv4 address of the specified network interface. If not set, the IPv4 address of the interface of the first default route is used.
• ipaddr6(name=NULL) – Get the IPv6 address of the specified network interface. If not set, the IPv6 address of the interface of the first default route is used.
• uid(name) – Get the UID of the specified user.
• gid(name) – Get the GID of the specified group.
• sharedfolder_path(name) – Get the full path of the specified shared folder.
• conf_get(id, uuid=NULL) – Get the specified database configuration object.
• tz() – Get the time zone of the host.

The following filters are currently available:

• get(key, default=NULL) – Get the specified key, e.g. foo.bar.baz from a dictionary.

Here are several examples that make use of the DSL:
