[midPoint] Docker Images and Screencasts for You

[Evolveum Marketing]

Dear midPoint community,

 From time to time everyone needs some help. Sometimes it is enough just 
to get answers and for these cases the wiki <https://wiki.evolveum.com/> 
is a great source of information. Other times it is not enough as we 
need to understand the problem more deeply in order to move forward. It 
has already been few years since the Book 
<https://evolveum.com/midpoint/midpoint-guide-about-practical-identity-management/> 
– and I really mean to write capital B – called “Practical Identity 
Management With MidPoint” started from blank page and it is still 
growing and growing (many thanks to Radovan and all other contributors 
for the great work and for a lot of time spent on it). If you never saw 
it, I would recommend it – at least for fast reading as a great 
structured source of information helping to understand some relations 
and consequences connected to the topic in general and ofcourse also in 
a relation with midPoint.

Even if we have a great static source of information available, it could 
still be not enough. Sometimes we need to see it – or even better – we 
need to try it. And when we want to try something, the ideal situation 
is when we can just run it without installation and simply remove / 
delete it once done while keeping the system clean. The Docker 
environment is ideal for it. For this purpose we have prepared Alpine 
based Docker images. It is a little bit optimized with Docker specifics 
in mind so in comparison with the original Ubuntu based midPoint Docker 
images, which have been available for some time already, we are on 1/3 
of the size (compressed image has around 320 MB). Based on this Alpine 
image with midPoint we have also prepared Docker-compose files 
<https://github.com/Evolveum/midpoint-docker> (directory: book) covering 
some chapters of the Book and using the sample files already mentioned 
in the Book. The goal was set to only do necessary changes to the sample 
files in order to demonstrate that it is really working. Example of the 
necessary change is to change the host from localhost to the name of the 
container.

The chapter environment is composed to have working application with 
predefined things so your focus may be directly on the subject of the 
chapters (e.g. import account from the resource, provision to the 
resource, create the role, set the object template). As the backend for 
the application data PostgreSQL version 13 is used. Resource interaction 
is demonstrated with PostgreSQL and OpenLDAP. Default version of 
midPoint in the Docker compose file is set to 4.2. There are also other 
Alpine based images available, which can be used instead of 4.2. In case 
you prefer demonstration on other supported versions, available tags 
<https://hub.docker.com/r/evolveum/midpoint/tags> are latest-alpine, 
4.2support-alpine, 4.2-alpine, 4.1support-alpine, 4.1-alpine, 
4.0support-alpine and 4.0.2-alpine. You can use them to try any 
processed chapter of the Book or you can easily use them to test any 
other use cases with some demo objects and already set up resources.

As we were preparing working Docker environments we decided to add 
something special, which was one of our Christmas gifts for the 
community – the screencasts 
<https://evolveum.com/holiday-season-gift-from-evolveum-to-watch-and-learn/>. 
For all the chapters available as docker-compose we made short casts to 
show it. We finalized the post production processing of 3 recorded 
videos. You can use them to visualizate the Book if you prefer this form 
of information. Feel free to share them in order to show how easy it can 
be for anyone who wants to know things but doesn’t have enough time to 
go though the Book or to try it by themselves (e.g. friends, colleagues, 
boss). We have spent extra time to prepare this another source of 
information and we will be happy if it helps you to better understand 
the topic or save some time in your activities related to the great 
midPoint application.
