We have gathered a few ready-to-run Docker stacks in our public stack-play GitHub repository. But sometimes you need Kafka, Zookeeper and OpenNMS quickly on a baremetal deployment without Docker. Here a few quick notes how to get the bare minimum up and running. Zookeeper Install OpenJDK 11 JRE sudo apt install -y openjdk-11-jre Create a user for zookeeper sudo adduser --system --home /opt/zookeeper --disabled-login zookeeper Create a logs directory sudo mkdir /var/log/zookeeper sudo chown zookeeper:nogroup /var/log/zookeeper -R Install zookeeper Continue readingSetting up a VMware Test environment
To test functions like importing OVA files in VMware ESXi and with vCenter the trial phase and a local deployment can be used. You need the following requirements: VMware Workstation on Windows or VMware Fusion on Mac OSX VMware Hypervisor ISO image to install the ESXi host system VMware vCenter ISO image for local deployment If you just want to learn how it works you can get a 60 days trial license registering an account on VMware.
