Cannot install mongodb

[roldengarm]

I'm trying to install mongodb, but am having trouble, as it seems neither init nor systemd are available.

I've got this as a script which installs mongodb fine.

sudo DEBIAN_FRONTEND=noninteractive apt-get install -y tzdata
sudo apt-get install -y gnupg curl
curl -fsSL https://www.mongodb.org/static/pgp/server-7.0.asc | sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg --dearmor
echo "deb [ signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] http://repo.mongodb.org/apt/debian bookworm/mongodb-org/7.0 main" | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list
sudo apt-get update          
sudo apt-get install -y mongodb-org
ps --no-headers -o comm 1

However, at the end it shows:
System has not been booted with systemd as init system (PID 1). Can't operate.
If I try via init I get an error it can't find service mongod

sudo service mongod start

I neither can run a docker image, so I feel I'm stuck here.

I also tried running it manually via sudo /usr/bin/mongod & but that doesn't seem to work; at a later step it can't access a mongodb at localhost.
