Trying to set up a modern icinga master with all the fancy new components and realized that the icingadb (not icingadb-redis) package was missing from the repo/instructions here.
Here's how I built it:
git clone https://git.icinga.com/packaging/rpm-icingadb.git
cd rpm-icingadb
curl -LO https://github.com/Icinga/icingadb/archive/refs/tags/v1.1.0.tar.gz
sed -i '/^Version/c\Version: 1.1.0' icingadb.spec
sed -i '/^BuildRequires: git$/a BuildRequires: go' icingadb.spec
mock --dnf --clean --spec icingadb.spec --sources=. --result=result --build
mock --dnf --clean --sources=. --result=result --enable-network --rebuild result/icingadb-1.1.0-2.el9.src.rpm
