canasta maintenance exec

Execute a command in a container

Synopsis

Execute an arbitrary command inside a container of a Canasta instance.

With no arguments and no --service flag, lists the running services. The default service is "web" (the MediaWiki container).

Use --stdin-file to feed a file to the command's standard input — for example, piping wikitext to maintenance/run.php edit <page>. The file is read on the controller, so it works for local, remote, and Kubernetes targets alike. Content is read as text (UTF-8).
