what is monitor?
Monitor is a web app to provide structure for managing your servers, builds, deployments, and automated procedures.
docker
Monitor is opinionated by design, and uses docker as the container engine for building and deploying.
monitor
Monitor is a solution for handling for the following:
- Build application source into auto-versioned images.
- Create, start, stop, and restart Docker containers, and view their status and logs.
- Manage repositories on remote servers.
- Keep a record of all the actions that are performed and by whom.
- View realtime and historical system resource usage, and alert for out of bounds values.
architecture and components
Monitor is composed of a single core and any amount of connected servers running the periphery application.
monitor core
The core is a web server that hosts the core API and serves the frontend to be accessed in a web browser. All user interaction with the connected servers flow through the core. It is the stateful part of the system, with the application state stored on an instance of MongoDB.
monitor periphery
The periphery is a stateless web server that exposes API called by the core. The core calls this API to get system usage and container status / logs, clone git repos, and perform docker actions. It is only intended to be reached from the core, and has an address whitelist to limit the IPs allowed to call this API.
core API
Monitor exposes powerful functionality over the core's REST API, enabling infrastructure engineers to manage deployments programmatically in addition to with the GUI. There is a rust crate to simplify programmatic interaction with the API, but in general this can be accomplished using any programming language that can make REST requests.
permissioning
Monitor is a system designed to be used by many users, whether they are developers, operations personnel, or administrators. The ability to affect an applications state is very powerful, so monitor has a granular permissioning system to only provide this functionality to the intended users. The permissioning system is explained in detail in the permissioning section.
User sign-on is possible using username / password, or with Oauth (Github and Google). Allowed login methods can be configured from the core config.
