support already present in <ibek-support>
support present as git project
support not present at all → put in the condition 2

Use an existing ibek support

If a support is present in <ibek-support>, it's very simple to use it just create a yaml that instantiates your device(s).

title	Docker image creation and run as ioc

docker run -p 5064:5064/udp -p 5064:5064/tcp -p 5065:5065/udp -p 5065:5065/tcp -it -v .:/epics/ioc/config baltig.infn.it:4567/epics-containers/infn-epics-ioc:localdevel

A generic asyn motor OPI interface can be used to drive the motor. Motor OPIs Remember to add localhost to your phoebus

...

Once the IOC runs correctly as docker can be inserted in the EPIK8S configuration

Build a support from existing git support

This is path is more complex, but gives much more satisfaction, in fact each time you add a new support as much generic possible you greatly simplify the life of your self and in principle many other people will use the your support.

Step 1 create a directory inside ibek-support

Create by copy and renaming one of the existing support. Suppose you want to add the support for <mydevmodule>, you should have:

...

So in general just two file must be added: install.sh and mydevmodule.ibek.support.yaml.

install.sh

This file contains instructions on howto retrieve, compile and link dependencies of your module mydevmodule. In general if the mydevmodule is well structured from a build epics point of view needs only to be patched like that:

Code Block

language	bash
title	install.sh

#!/bin/bash

# ARGUMENTS:
#  $1 VERSION to install (must match repo tag)
VERSION=${1}
NAME=<mydevmodule>  ## as compare in the git repository
FOLDER=$(dirname $(readlink -f $0))

# log output and abort on failure
set -xe

# get the source and fix up the configure/RELEASE files
ibek support git-clone ${NAME} ${VERSION} --org http://gitrepo ## repository git root
ibek support register ${NAME}

# declare the libs and DBDs that are required in ioc/iocApp/src/Makefile
ibek support add-libs <mydevmodulelib> <support1lib> <support2lib> asyn ## optional libraries that must be linked
ibek support add-dbds <mydevmodule>.dbd <optsupport1.dbd> <optsupport2>.dbd ### optional dbd supports
# global config settings
${FOLDER}/../_global/install.sh ${NAME}

# compile the support module
ibek support compile ${NAME}
# prepare *.bob, *.pvi, *.ibek.support.yaml for access outside the container.
ibek support generate-links ${FOLDER}

mydevmodule.ibek.support.yaml

This also has a very simple syntax and gives instructions on how to expand a future yaml configuration.
