Why Ansible is better than shell scripts?
Ansible can perform the function of not only setting up your systems, but also testing them for correctness. By contrast, a shell script can be very dangerous to run more than once unless you’re extremely careful and know exactly what every line does.
Why Ansible is better than chef and Puppet?
When it comes to ease of setup and installation, Ansible dominates the other two tools as it has ‘agentless’ architecture. Chef and Puppet follow master-agent or master-slave architecture.
What is Puppet chef Ansible used for?
Generally, Ansible, Puppet, SaltStack, and Chef are considered to be configuration management (CM) tools and were created to install and manage software on existing server instances (e.g., installation of packages, starting of services, installing scripts or config files on the instance).
What is the difference between shell and command in Ansible?
The shell module in Ansible is used to execute all Shell commands against the target Unix-based hosts. The shell module executes commands in nodes or Shell scripts. In the command module, the given command executes on all selected nodes. The executed command will not be processed through the shell.
What are Ansible scripts?
An Ansible playbook is an organized unit of scripts that defines work for a server configuration managed by the automation tool Ansible. Ansible plays are written in YAML. Every play is created by an administrator with environment-specific parameters for the target machines; there are no standard plays.
What are the benefits of Puppet in DevOps?
These are the main advantages of Puppet:
- Puppet saves time by increasing deployment speed.
- Unlike other tools, it keeps abreast of configuration changes at regular intervals, which increases security.
- It uses an easy to learn language called DSL (or Domain Specific Language) to manage host configurations.
Is Chef better than Ansible?
The chef is older, has better documentation, and can handle difficult tasks. But, it is trickier to install as compared to Ansible. Chef’s Ruby DSL is preferred by developers and DevOps engineers. But, it has a steep learning curve as compared to Ansible, which uses simple YAML.
Which is better Ansible or Puppet?
The difference is that ansible-playbook can be run from centralised places, whereas Puppet needs an agent to run on each node. In short, Puppet will always require an extra component/package to be installed on the destination server to make it all work, regardless if you go masterless or not.
What is the primary difference between Shell and command module?
The Shell module runs a command through a shell, by default /bin/sh. This can be changed with the option executable. Piping and redirection are here therefor available. The command module is more secure, because it will not be affected by the user’s environment.
What is raw module in Ansible?
Note. This module is part of ansible-core and included in all Ansible installations. In most cases, you can use the short module name raw even without specifying the collections: keyword.
Why Ansible is better than puppet and chef?
Compared with Puppet and Chef, Ansible was developed to simplify complex orchestration and configuration management tasks. Ansible platform is written in Python and it allows the users to script commands in YAML as an imperative programming paradigm.
What programming language is Ansible written in?
And Ansible uses YAML syntax. Complex tasks are handled in configuration files called playbooks, and commands can be written in almost any programming language. Plus, Ansible is written in Python, which is built into most Unix and Linux deployments, making setup even easier/faster.
What is the difference between anansible and puppet?
Ansible has a secondary node in case the active node fails, and Puppet has more than one master in case the original master fails. Both tools are highly scalable, meaning they can handle a big increase in nodes with no problem.
What is puppet and how does it work?
Unlike the other tools we’ve looked at, Puppet uses a declarative approach to building configuration files. The imperative approach used by Ansible and Chef requires users to detail the steps the software should take to achieve the desired state on a server.
