If you wonder how to automatically deploy 20 nodes of Docker Swarm and run 100 Docker containers in it, then continue reading. I will show how to achieve this by using Terraform, Ansible and Portainer. Course of action What is Docker Swarm and why I need to have 20 of these? Docker is containers toolkit utilizing cgroups, namespaces which allows to control and share resources of the CPU and operating system. Docker Swarm its a special kind of runtime mode, which allows to run multiple clustered nodes which can be separate physical computers or virtual machines. It gives us scalability
If you run digital services platform or critical infrastructure then most probably you are covered by NIS 2 and its requirements including those concerning information security. Even if you are not covered by NIS 2, then still you may benefit from its regulations which seem to be similar with those coming from ISO 27001. In this article I show how to automatically deploy anti-rootkit and anti-virus software for your Linux workstations and servers. TLDR By using rkhunter anti-rootkit and ClamAV anti-virus you are closer to NIS 2 and ISO 27001 and farther away from threats like cryptocurrency miners and ransomware.
I already have over 10 virtual machines in my home virtual environment. It is the number I find enough to start using some automation tools like Ansible. Installing Ansible on Ubuntu or CentOS systems is straightforward, just use regular apt or yum commands. With Ansible you can use commands or create scripts. First you should start with hosts definition file which by default is located at /etc/ansible/hosts. You can use different hosts file but then you need to point it while running commands. This one is default, so no need to do anything special here. Now going quickly to Proxmox’s
