Docker vs Puppet Labs: What are the differences?
1. Containerization vs Configuration Management: The key difference between Docker and Puppet Labs is that Docker focuses on containerization, allowing you to package and run applications in isolated environments, while Puppet Labs is a configuration management tool used for automating the setup and management of infrastructure. 2. Use Case: Docker is primarily used for application deployment and scaling, while Puppet Labs is more suited for automating configuration and management of servers and infrastructure. 3. Technology Stack: Docker relies on container technology, such as Docker Engine, to create and manage containers, whereas Puppet Labs utilizes Puppet software for configuration management tasks. 4. Scalability and Performance: Docker is known for its lightweight containers that can be easily scaled up or down based on demand, providing high performance, while Puppet Labs may require additional resources for server configuration tasks, impacting scalability and performance. 5. Learning Curve: Docker may have a steeper learning curve due to its complex containerization concepts, while Puppet Labs might be easier to learn for those familiar with traditional configuration management tools. 6. Community and Ecosystem: Docker has a large community and ecosystem with a wide range of tools and resources available, while Puppet Labs also has a strong community but may offer more specialized tools for configuration management tasks.
In Summary, Docker and Puppet Labs have distinct focuses on containerization and configuration management, respectively, with differences in their use cases, technology stack, scalability, learning curve, and community support.
I'm just getting started using Vagrant to help automate setting up local VMs to set up a Kubernetes cluster (development and experimentation only). (Yes, I do know about minikube)
I'm looking for a tool to help install software packages, setup users, etc..., on these VMs. I'm also fairly new to Ansible, Chef, and Puppet. What's a good one to start with to learn? I might decide to try all 3 at some point for my own curiosity.
The most important factors for me are simplicity, ease of use, shortest learning curve.
I have been working with Puppet and Ansible. The reason why I prefer ansible is the distribution of it. Ansible is more lightweight and therefore more popular. This leads to situations, where you can get fully packaged applications for ansible (e.g. confluent) supported by the vendor, but only incomplete packages for Puppet.
The only advantage I would see with Puppet if someone wants to use Foreman. This is still better supported with Puppet.
If you are just starting out, might as well learn Kubernetes There's a lot of tools that come with Kube that make it easier to use and most importantly: you become cloud-agnostic. We use Ansible because it's a lot simpler than Chef or Puppet and if you use Docker Compose for your deployments you can re-use them with Kubernetes later when you migrate
lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.
