It can use a configuration file very similar to a docker-compose.yml, with a few nuances. Using docker stack instead of docker compose offers several advantages, such as the ability to manage a Swarm cluster across multiple machines or the capability to work with docker secret combined with docker context , a feature that allows executing ...
Container clusters need to be managed. This includes functionality to create a cluster, to upgrade the software or repair it, balance the load between existing instances, scale by starting or stopping instances to adapt to the number of users, to log activities and monitor produced logs or the application itself by querying sensors.
It is open-source and the suite includes software provisioning, configuration management, and application deployment functionality. [2] Originally written by Michael DeHaan in 2012, and acquired by Red Hat in 2015, Ansible is designed to configure both Unix-like systems and Microsoft Windows.
Pyinfra is an agentless server configuration management tool created in Python. Its execution speed is up to 10 times faster than Ansible. [120] Pyinfra is also excellent for system integration, as it can control SSH connections, Docker, Terraform, Ansible, etc. using a mechanism called a connector. Pyinfra can be run ad hoc or through the API ...
Vagrant is a source-available software product for building and maintaining portable virtual software development environments; [5] e.g., for VirtualBox, KVM, Hyper-V, Docker containers, VMware, Parallels, and AWS. It tries to simplify the software configuration management of virtualization in order to increase
Container Linux provides no package manager as a way for distributing payload applications, requiring instead all applications to run inside their containers. Serving as a single control host, a Container Linux instance uses the underlying operating-system-level virtualization features of the Linux kernel to create and configure multiple containers that perform as isolated Linux systems.
LXC was initially developed by IBM, as part of a collaboration between several parties looking to add namespaces to the kernel. [7] It provides operating system-level virtualization through a virtual environment that has its own process and network space, instead of creating a full-fledged virtual machine.
Configuration is performed by arranging predefined actions into sequences called pipelines. Pipelines can be triggered automatically on push to branch, manually, or recurrently. Actions include Docker-based builds, deployment to FTP / SFTP and IaaS services, delivery to version control, SSH scripts, website monitoring and conditional notifications.
