So I have some possibly dumb questions around use of the distrobuilder snap.
I want to use the distrobuilder 2.0 snap to build a custom Oracle 8 LXD image. I have a few questions around that. I was able to successfully install and setup the distrobuilder 2.0 snap on Oracle 8.3 as follows after first installing snapd (which requires the oracle8 epel) :
[ubuntu@o84sv1 ubuntu]$ sudo dnf -y install oracle-epel-release-el8
[ubuntu@o84sv1 ubuntu]$ sudo dnf -y install snapd
[ubuntu@o84sv1 ubuntu]$ sudo systemctl enable --now snapd.socket
[ubuntu@o84sv1 ubuntu]$ sudo ln -s /var/lib/snapd/snap /snap
[ubuntu@o84sv1 ubuntu]$ sudo snap install distrobuilder --classic
[ubuntu@o84sv1 ubuntu]$ distrobuilder --version
2.0
So then I went to the distrobuilder How to Use documentation.
However, the āHow to Useā seems to be based on the non-snapd installation method (i.e. Installation from Source) and additional searches for information on using the snapd variant of distrobuilder are pretty sparse.
Is there any good documentation for How to Use if you are using the snapd implementation of distrobuilder ?
There is a thread here that suggests a path forward that pretty much covers how to create for example a CentOS 7 LXD image with the snapd distrobuillder so I can probably find my way through with those bits.
However that brings me to my next question.
The jenkins server has had this banner on it that says āJenkins is going to shut down no further builds will be performed.ā That message has been on a red banner at the top of the Jenkins server landing page for as long as I can recall and I just want to understand ā¦ does that mean āthe Jenkins server is shutting down for a backupā or does it mean that āthe Jenkins server is going away permanently.ā
If Iām understand the process correctly, the source for the yaml files will the the github here, for example for Oracle Linux here so I am atm planning to pull yaml files from the github.
As a ānaiveā first cut at creating the aforementioned centos7 LXD using snapd distrobuilder for example:
[root@o84sv1 ~]# distrobuilder build-lxd centos.yaml -o image.architecture=x86_64 -o image.release=7
Error: Failed to get definition: open centos.yaml: no such file or directory

When I try the exact same syntax for an Oracle8 build I get that same error at line 138 about āmapping values are not allowed in this context.ā
So Iām just trying to get up to speed on using the snapd of distrobuilder (because I work so much on redhat-family linuxes) to build images and I just need some clarification on how to go about building a custom Oracle 8 LXD image, and then also just want to understand the medium- to long-term fate of the Jenkins server.
Thanks!
