This tool supports building container images for Generic EPICS IOCs and generating IOC Instances from those Generic IOCs at container runtime. It is targetted at running IOCs in Kubernetes, but the images it creates can execute in any container runtime, such as docker or podman.
PyPI pip install ibekSource code https://github.com/epics-containers/ibek Documentation https://epics-containers.github.io/ibek Releases https://github.com/epics-containers/ibek/releases
There have been a number of breaking changes since version 1.8.0. These are primarily to support RTEMS cross compiled IOCs. But we have also taken the opportunity to clarify the CLI.
All changes are compatible with 2.0.0 of ibek-support and 3.4.0 of all other epics-containers repos. When using ioc-template 3.4.0 to update your generic IOCs, make sure you also update the ibek-support submodule to 2.0.0 or newer, then you should have all compatible versions.
The documentation is still under construction. For the moment the best pages to read are the following:
- Modules, Definitions and Entities A description of the basic concepts of ibek.
- naming conventions in support YAML Conventions for the YAML that ibek consumes.
- epics-containers documentation Documentation and tutorials for the epics-containers suite of tools.
The command line interface for ibek is as follows. The most up to date version
of this can be found by running ibek --help.
