sudo apt update -y
sudo apt install puppetserver
sudo tac /etc/default/puppetserver
sudo grep ARGS /etc/default/puppetserver
sudo grep 1g /etc/default/puppetserver
sudo sed -i 's/1g/2g/g' /etc/default/puppetserver

Start portainer

docker volume create portainer_data
docker run -d -p 32125:8000 -p 32126:9443 --name portainer --restart=always \
-v /var/run/docker.sock:/var/run/docker.sock \
-v portainer_data:/data portainer/portainer-ce:latest

log on immediately to https://<vm_ip>:32126 and create a account and password because portainer container will be timeout

build containers

git clone https://github.com/crunchy-devops/noble-puppet.git
cd noble-puppet
cd alma
docker build -t alma-puppet .
cd ../alpine
docker build -t alpine-puppet .
cd ../ubuntu
docker build -t ubuntu-puppet .

Start containers

# add-host is this internal DNS entry for the puppet server
docker run --name target1 -d -p 2222:22 --add-host=puppet:10.200.15.208 --hostname=alma.com alma-puppet
docker run --name target2 -d -p 2223:22 --add-host=puppet:10.200.15.208 --hostname=alpine.com alpine-puppet
docker run --name target3 -d -p 2224:22 --add-host=puppet:10.200.15.208 --hostname=ubuntu.com ubuntu-puppet

Adding a DNS entry on all containers

ping -c 3 puppet # Test ping
puppet agent -tv # Check if it's work fine

List of Certificates Authority on server

# as root on puppet server host
/usr/bin/puppetserver ca list -a # list all current certificats

Sign all certificates

# as root on puppet server host
/usr/bin/puppetserver ca sign -a

Caveats, useful commands

sudo puppet resource service puppet ensure=stopped
sudo puppet resource service puppetserver ensure=stopped
sudo puppetserver ca setup
sudo puppet resource service puppetserver ensure=running
sudo puppet resource service puppet ensure=running
