MidPoint Deployment Language Draft

Last modified 25 May 2021 16:03 +02:00


This document describes new language that could be used to handle configuration changes and their deployment in midPoint environments.

Handling configuration changes

Changes in configuration are part of day to day operation within midPoint operations. New resources being managed, old resources being decommissioned, upgrades being done. Each configuration change can be non-trivial and can contain multiple steps. This creates challenges on multiple fronts:

  • How document steps being executed during configuration change?

  • How to make sure all steps were executed and in correct order?

  • How to manage change execution in multiple environments, e.g. test, acceptance, QA, production?

  • What if someone else have to execute configuration change in higher environments (eg. operation team responsible for production)?


To address problems mentioned in previous chapter one should have a tool that can describe how configuration change should be applied. As an example we can use IT infrastructure. Currently, there are many tools used to handle configuration changes like Ansible, Chef, Terraform, etc. Similar approach could be used to deploy changes in midPoint environment.

We could describe changes for midpoint environment using YAML file and then use tool to execute changes described in file. Similarly, we could generate documentation (steps). Tool should be integrated with others in midPoint ecosystem (studio, ninja, midscribe).

Example of configuration change:

name: some package name
description: some description

    - host1
    - host2
    - host3
    - host4
    plain: asdf.properties
    encrypted: credentials.kdbx
    name: jdoe
    password: FROM_SOMEWHERE

  - name: Upload template
      raw: true       # optional
#      object: text
#      file: something.xml  # could be directory
#      test: true      # test connection if object was resource
  - name: Task handling
      # maybe suspend/resume all  hat will put some identifier to documentation/description to know how to resume them later. how about ordering?
      command: start  # suspend | resume
#      oid: some-oid   # name or oid needed or file to be uploaded beforehand
#      name: some-name
#      file: task.xml
#      wait:           # wait until task is finished? maybe timeout
#  - name: get object
#    get:
#      raw: true
#      oid: 123
#      name: some name
#  - name: sync midpoint home
#    home:
#      sync: true
#      command: upload # or something similar...
#  - name: list objects
#    list:
#      raw: true
#      query: TODO     # how to query
#      type: user
#  - name: modify object
#    modify:
#      raw: true
#      delta: xml delta
#      file: pointer to file/directory
#  - name: manual step
#    manual:
#      title: some title
#      description: asdf
#      confirmation: true

Missing Features

  • midpoint.home folder manageable via REST API



Unsorted Notes


  • what about new midpoint rest endpoint that will be able to manage midpoint-home folder???? Yummy REST CRUD for file system changes

  • tasks: maybe import one account for testing/validation purposes

  • validate midpoint version?

  • allow elevate user in rest

  • timeout for all tasks

  • timeout for rest calls

  • find a way to pause/resume playbook (during manual steps for example)

  • test resource connection against all urls defined (as optional)

  • delete object

Todo Optional

  • find a way to do tasks in parallel

  • check status of cluster, metrics etc, print them

  • figure out how to validate progress when uploading or waiting for task to finish

  • allow extendability via plugins or custom tasks
