Encapsulation with Vamos Deploy

Vamos Deploy encapsulates an application with it's binaries, all it's dependant libraries and it's runtime configuration. The 'capsule' is a self-contained runtime instance of an application which can be deployed to multiple hosts with a single command. Capsules do not conflict with each other and can happy exist side-by-side. There are no hard walls though, we rely on users abiding by the rules and good neighbourly conduct. In Vamos jargon, we call an encapsulated application a 'grid'.

On each host there can be one or more local repository. Once registered, a repository can be added to any number of grids. When a grid is 'deployed' each local repository, associated with that grid, is updated with all the required software packages and configuration. The application is ready to go! Takes just 2 commands:



$ vamos grid JupiterDev1 addrepo myrepo-myhostname
$ vamos grid JupiterDev1 deploy

All software and configuration is stored within the local repository, which on Linux is a directory structure under /vamos. Software is not scattered around the filesystems it's neatly contained in a dependable location, irrespective of the operating system.

In a future post we will examine how an application accesses its dependancies and runtime configuration from within the local repository.
