Create a GIT repository

Every IOC/application MUST have a GIT repository associated. A project must be created under https://baltig.infn.it/lnf-da-control or a different group like for instance:

https://baltig.infn.it/infn-epics

httpshtps://baltig.infn.it/epics-containers

Pay attention to not set the project private otherwise will not be possible to load it into the EPIK8S.

...

Create .devcontainer directory into your vscode workspace and create a devcontainer.json like the following:

C/C++ IOC Development

A docker image that can be used as epics7 for development is:

baltigghcr.infn.it:4567/epics-containersio/infn-epics/infn-epics-ioc:devel-developer

It contains several support modules used in deployment.

Epics Getting Started

Simple command line interaction

For So for instance to start a shell and mount the current directory '.' to /mnt :

The The example here below initialize a directory with a standard ioc/support tree:

Code Block

language	bash
title	Epics support/example

docker run -p 5064:5064/udp -p 5064:5064/tcp -p 5065:5065/udp -p 5065:5065/tcp -v .:/mnt -it baltigghcr.infn.it:4567/epics-containersio/infn-epics/infn-epics-ioc-linux-developer:devellatest bash
## docker shell
cd /mnt ## go in the . directory that is mounted 
mkdir mynewiocsample
cd mynewuicsample
makeBaseApp.pl -t example mynewiocsample
make

Setup a target container

Create .devcontainer directory into your vscode workspace and create a devcontainer.json like the following:

 # create DB and support
makeBaseApp.pl -i -t example mynewiocsample  mynewiocsample # create iocboot directory ## as appname use mynewiocsample

make
cd mynewiocsample/iocboot/mynewiocsample # st.cmd
chmod +x ./st.cmd ## to make it executable
./st.cmd # start the ioc and load example DB

It use the EPICS scripts makeBaseApp.pl to create a valid ioc tree directory tree.

Setup a target container

If you have an account on github (strongly suggested), you can use a predefined github template to create a new git project from template: https://github.com/infn-epics/epics-devcontainer-template

GIGE Camera

Gigavision cameras that support GIGE protocol can be acquired by ADAravis support that is already included in production/development infn-epics-ioc container.

NOTE: this container must be launched with the --network=host to access GIGE cameras.

Devel example

Example development the arv-tool command inside the container can be used to explore cameras that can be accessed:

Code Block

language	bash
title	Camera development start

docker run --network=host -v .:/epics/ioc/config -it baltig.infn.it:4567/epics-containers/infn-epics-ioc:devel bash
..

root@chaost-camera01:/epics/generic-source/ioc/config# arv-tool-0.8 
Basler-a2A1920-51gmBAS-40426579 (192.168.115.49)
Basler-a2A2600-20gmBAS-40437925 (192.168.115.48)
Basler-scA640-70gm-24159532 (192.168.115.50)

Production example

The configuration and pipelining of plugin can be very difficult and error prone, so the IBEK + templating support is highly recommended IBEK.

Create a directory <test> and create a camera_template.j2 file like that:

camera template

REMOTE POD DEVELOPMENT (NEW)

It may be possible that some IOC access a network or HW that is not available locally.

The administrator could have created development pods that run exactly where they should run, this pods have all the environment and the minimum packages to develop epics and softioc applications.

These pods are accessible via ssh and specific ports, for these pods it is possible to setup VSCODE remote development via ssh.

These pods runs in the cluster so they can be view by gateways and other tools.

Allocation of a new pod for development

The allocation of a new pod for development is straightforward, it needs to add an entry in the EPIK8s beamline yaml configuration (deploy/values.yaml) see EPIK8s Beamline.

In the following example are instantiated different developments pods:

development-andrea, it is constrained to run on the nodes that may access sparc-magnets network
development-alessandro, it is constrained to run on the nodes that may access sparc-cams network
development-gpu it is contrained to run on nodes that have a GPU
development-generic it's not constrained and may run everywhere

To access a development pod simply use ssh dante@<one machine cluster address i.e 10.10.6.18> -p <ssh_nodeport>.

Entry in values.yaml

Code Block

language	yaml
title	values.yaml

- name: "development-andrea"

      autosync: false ## restart automatically on changes
      devtype: development
      networks:
        - name: "control"
          annotation: "sparc-magnets"
      ssh_nodeport: 30022
      securityContext:
        runAsUser: 0
        runAsGroup: 0
    
    - name: "development-alessandro"

      autosync: false ## restart automatically on changes
      devtype: development
      networks:
        - name: "control"
          annotation: "sparc-cams"
      ssh_nodeport: 30023
      securityContext:
        runAsUser: 0
        runAsGroup: 0

	- name: "development-gpu"
      image: "ghcr.io/infn-epics/infn-epics-ioc-developer"
      charturl: 'https://baltig.infn.it/epics-containers/ioc-chart.git'
      autosync: false ## restart automatically on changes
      devtype: development
      runon:
        - name: "control"
          annotation: "gpu"
      ssh_nodeport: 30029
      securityContext:
        runAsUser: 0
        runAsGroup: 0

	- name: "development-generic"
      image: "ghcr.io/infn-epics/infn-epics-ioc-developer"

      autosync: false ## restart automatically on changes
      devtype: development
      
      ssh_nodeport: 30028
      securityContext:
        runAsUser: 0
        runAsGroup: 0

So for instance:

Code Block

language	yaml
title	values.yaml

ssh epics@10.10.6.18 -p 30022 ## will access pod development-andrea
ssh epics@10.10.6.18 -p 30023 ## will access pod development-alessandro
ssh epics@10.10.6.18 -p 30024 ## will access pod development-gpu

ssh config client

It can be useful for VScode development to add a specific entry in .ssh/config, adding these lines it will be possible to connect just doing ssh epics@10.10.6.18 and passord

Code Block

language	yaml
title	values.yaml

Host 10.10.6.18
  HostName 10.10.6.18
  User epics
  Port 300xx ## replace with yours
  StrictHostKeyChecking no
  UserKnownHostsFile /dev/null

IBEK support and "IBEKisation step"

To allow an easy portability of a IOC (in particular IOC that can run inside containers) once an IOC or support is ready and tested, the next step is the DiamonLightSsource "ibekization". This steps in few words allows to instantiate a general st.cmd with support through a simple YAML file.

1- Add a new support in infn-epics-ioc

Once your IOC has its own GIT project, clone the infn-epics-ioc project that is the project the build the container with all IOC supports for infn.

Code Block

language	shell
title	Shell

git clone https://github.com/infn-epics/infn-epics-ioc.git --recurse-submodules

This project contains the following layout:

infn-epics-ioc directory tree

infn-epics-ioc-dir

Code Block

├── tests                        <-- 4 test directory

2- Create support directory

Suppose your new support is named <mynewsupportname>

create a directory in ibek-support-infn/<mynewsupportname> this directory must contain two files:

- mynewsupportname.ibek.support.yaml
- mynewsupportname.install.yml

like in the example:

Code Block

language	shell
title	Shell

ibek-support-infn
│   ├── mynewsupportname
│   │   ├── mynewsupportname.ibek.support.yaml   <== here the st.cmd yaml translation instruction
│   │   ├── mynewsupportname.install.yml         <== here the instruction to install
│   ├── Tektronix_MSO58LP
│   │   ├── Tektronix_MSO58LP.ibek.support.yaml
│   │   └── Tektronix_MSO58LP.install.yml

3- Create the install support file mynewsupportname.install.yml

mynewsupportname.install.yml

Code Block

language	yaml
title	mynewsupportname.install.yml

# yaml-language-server: $schema=../../ibek-support/_scripts/support_install_variables.json

module: mynewsupportname ## your git project name
version: devel ## your reversion/tag

# this module uses modbus so requires none of its own libs/dbds
organization: https://github.com/infn-epics/ ## your git organization name

dbds:								## here the dbds used by your ioc/support
  - asyn.dbd
  - stream.dbd
  - calc.dbd
  - asSupport.dbd
  - sscan.dbd
  - <mynewsupportname>.dbd

libs:								#here 
  - asyn
  - stream
  - calc
  - autosave
  - <mynewsupportname>Support  ## if you have support libs


protocol_files:
  - db/<mynewsupportname>.proto ## if you have protocols file

4- Create the support file mynewsupportname.ibek.support.yml

mynewsupportname.ibek.support.yaml

Here you have to instruct how the yaml expand in the st.cmd of your IOC. For example:

Code Block

language	yaml
title	mynewsupportname.ibek.support.yml

# yaml-language-server: $schema=https://github.com/epics-containers/ibek/releases/download/3.1.2/ibek.support.schema.json

5- Add the new support to the container

Edit Dockerfile and add two lines for mynewsupportname

Code Block

language	docker
title	Dockerfile

.....

COPY ibek-support-infn/motorMicos motorMicos/
RUN ansible.sh motorMicos

COPY ibek-support-infn/cagateway cagateway
RUN ansible.sh cagateway

COPY ibek-support-infn/mynewsupportname mynewsupportname   ## NEW support
RUN ansible.sh mynewsupportname							   ##

6- Build the container inside VScode

CTRL(or Command)+Shift+P (Rebuild Container or open directory in container)

If the build succeed your support has been re-compiled successfully, otherwise check the errors.

7- Create/update a JNJA2 template that use your new support

Your new support to be instantiated needs a YAML that parametrize the values that you defined in your support so for instance for your support a valid YAML could be:

Code Block

language	yaml
title	mynewsupportname.yaml

iocname: mynewioc
description: test


entities:
  - type: mynewsupportname.mycontroller
    name: MYCONTROLLER
    P: "MYBEAMLINE:TEST"
    IP: "192.168.1.1"
    TCPPORT: 4001
        
  - type: mynewsupportname.mychannel
    controller: MYCONTROLLER
    name: "PIPPO"
    channel: A1

Normally a particular module/IOC is re-used multiple time and may include many different types/cases instead to have many YAMLs to configure each of them a single JNJA2 template is written yaml.j2 JNJA2 is a powerful preprocess language that may be applied to any form of text to perform substitutions, logic and flow, it's used in many contextes to create templates.

So the previous YAML can be templated to be used by EPIK8S. In particular the yaml (deploy/values.yaml) that describes your EPIK8s beamline will initialize your template.

Code Block

language	yaml
title	mynewsupportname.yaml.j2

iocname: {{iocname}}
description: Templated test


entities:

  - type: {{devtype}}.controller
    name: MYCONTROLLER
    P: "{{iocprefix}}"
    IP: {{server}}
    TCPPORT: {{[port}}
  {%- for t in devices %}
  - type: {{devtype}}.channel
  	controller: MYCONTROLLER
  	name: "{{ t.name }}"
  	channel: {{ t.channel }}
  {%- endfor %}

8- Test your support with template

copy or update ibek-templates/templates directory

Once your have prepared your mynewsupportname.yaml.j2 place in a suitable directory inside ibek-templates/templates see infn epics ioc directory tree. For example if mynewsupportname belongs to the VAC subsystem an updated or new entry must be created into ibek-templates/templates/vac.

If it is an update the content of your mynewsupportname.yaml.j2 must be added to an existing template file adding for instance a new model of VAC of an existing template. If the support is completely new and for instance represent the first of a series of support a new directory can be created and the support file mynewsupportname.yaml.j2 copied in such directory.

Suppose the mynewsupportname is a completely new file.

update your deploy/values.yaml beamline description file

Copy your current epik8s beamline file deploy/values.yaml file in the tests directory see infn epics ioc directory tree. Add in some point of the ioc list your new ioc like that:

Code Block

language	yaml
title	Beamline EPIK8s description

- name: "caenelsfast"
      asset: "https://confluence.infn.it/x/nYD8DQ"
      charturl: 'https://baltig.infn.it/epics-containers/ioc-chart.git'
 .....

    - name: "mynewIOCNAME"								   ##  replace parameter iocname 
      asset: "https://confluence.infn.it/x/nYD8DQ"
      charturl: 'https://baltig.infn.it/epics-containers/ioc-chart.git'
      iocprefix: "SPARC:MAG:HZ"                            ### replace parameter iocprefix
      iocparam:
        - name: "server"                                   ### replace generic parameter server
          value: "192.168.197.102"
        - name: "port"                                     ### replacegeneric parameter port
          value: "4001"					
      autosync: false ## restart automatically on changes
      devtype: "mynewsupportname"                          ### a template file may contain different device types
      devgroup: mag										   
      opi: "mynewsupportname"
      template: "mynewsupportname" 					        ## or the name of the directory or file where your new template is
      networks:
        - name: "control"
          annotation: "sparc-magnets"
      devices:											   ## device list parameters that will be replaced in your template
        - name: "GUN01"
          channel: "6"
        - name: "AC1SOL01"
          channel: "7"
        - name: "AC1SOL02"
          channel: "8"

test using epik8s-run

Inside the container terminal launch the utility epik8s-run that execute things as the EPIK8s will do:

Code Block

language	shell
title	Shell

rm /epics/ioc/config/* ## remove previous configs
epik8s-run tests/values.yaml mynewIOCNAME --native

This utility will take from your beamline values the ioc instance mynewIOCNAME will create a yaml using the template you wrote and will call the ibek utility to generate an ioc instance following the ibek support that you did.

So it tests a lot of things together and probably some error will be detected, even if most of typo errors can be avoided using vscode yaml schema.

Once the IOC starts everything can be committed step 9.

It's possible to check the yaml result of instantiation in /epics/ioc/config the yaml has the name like the template without .j2.

Code Block

language	shell
title	Shell

rm /epics/ioc/config/* ## remove previous configs
## the following will perform replacement and start the ioc
epik8s-run tests/values.yaml mynewIOCNAME --native

## check yaml 

more /epics/ioc/config/mynewsupportname.yaml
## the resulting st.cmd after ibek instantiation of mynewsupportname.yaml can be found in
more /epics/runtime/st.cmd

Chek Intermediate files generated

/epics/ioc/config/<mynewsupportname>.yaml resulting YAML after j2 replacement with parameters given from IBEK beamline/deploy/values.yaml
/epics/runtime/st.cmd resulting st.cmd after ibek replacement using the support mynewsupportname

9- Commit, Tag to create a new image

ibek-infn-support and ibek-templates are git subproject so to add your new support you should go in the directories:

Code Block

language	shell
title	Shell

cd ibek-infn-support 
git status
git add <mynewsupportname>
git commit -m "my first beautiful ibek support" .
git checkout main
git merge <hash/branch>
git push origin
cd ..
cd ibek-templates/templates

git add <mynewsupportdircontent>
git commit -m "my first beautiful ibek template" .
git checkout main
git merge <hash/branch>
git push origin

## now commit and push the epics-infn-ioc main project
cd ../../
git commit -m "my first beautiful support" .
git checkout main
git merge <hash/branch>
git push origin

## to create a new image a tag must be created
## list tags
git tag
git tag <last tag + 1 in minor or +1 in bump release (something temporary) <tag>b xx
git push origin <tagname created>

Release tags convention

The ufficial tags should have the following format : v<year>.<month>.<day> the test tags or fix during a day must have the suffix <bincremental number>

...

language	bash
title	Camera development start

...

Deploy on the target EPIK8S

...

ioc.yaml if your IOC is generic and has support in ibek see IBEK support
start.sh + other ioc startup files or submodules. The start.sh is the entry point that can perform some useful substitutions in case of multiple instances of same ioc and start your IOC.

...

Code Block

language	bash
title	Add your project as submodule

cd /<your <EPIK8Sfolder/configgit directory>/epik8-<beamline name> ## for example epik8-sparc
git pull --recurse-submodules ## to update remote changes
git submodule update --init ## to update eventually new submodules
cd  <config/iocs/<ioc_name>/scripts>
git pull ## updates to remote changes
cd ..
git add ./scripts/
git commit -m "updated IOC <ioc_name>"
git push origin

IBEK support and "IBEKisation step"

1- Add a new support in infn-epics-ioc

infn-epics-ioc directory tree

Anchorinfn-epics-ioc-dirinfn-epics-ioc-dir

2- Create support directory

3- Create the install support file mynewsupportname.install.yml

mynewsupportname.install.yml

4- Create the support file mynewsupportname.ibek.support.yml

mynewsupportname.ibek.support.yaml

5- Add the new support to the container

6- Build the container inside VScode

7- Create/update a JNJA2 template that use your new support

8- Test your support with template

copy or update ibek-templates/templates directory

update your deploy/values.yaml beamline description file

test using epik8s-run
