Docker is an open-source tool that programs the utilization ofan application inside a software container. The easiest method to grip the cluebehind Docker is to relate it to, well… customary shipping containers.
Why do we need Docker?
The shortlist of aids includes:
· Faster development method
· Handy application encapsulation
· The same performance on localmachine/dev/staging/production servers
· Easy and clear watching
· Easy to measure
Faster development process
There is no necessity to install 3rd-party apps like PostgreSQL,Redis, Elasticsearch on the system – you can run it in containers. Docker alsooffers you the capacity to run dissimilar types of the same applicationconcurrently. For example, say you essential to do some guide data migrationfrom a grownup version of Postgres to an innovative version. You can have sucha state in microservice planning when you need to create a new microservicewith a new version of the 3rd-party software.
Handy application encapsulation
You can bring your application in one part. Most programminglanguages, structures, and all operating structures have their own packingmanagers. And even if your application can be filled with its native packagedirector, it could be solid to make a port for another system.
Easy and clear monitoring
Out of the box, you have a united way to deliver log files fromall running containers. You don’t want to recollect all the particular routeswhere your app and its needs store log files and write custom hooks to handlethis. You can add an outside logging driver and monitor your app log files inone place.
Easy to scale
A properly enclosedapplication will refuge most of the Twelve Features. By design, Docker servicesyou follow its core values, such as structure over setting variables,communiqué over TCP/UDP ports, etc. And if you’ve complete your applicationright, it will be prepared for scrabbling not only in Docker.
Supported platforms
Docker’s nativeplatform is Linux, as it’s created on features providing by the Linux kernel.However, you can still run it on macOS and Windows. The only change is that onmacOS and Windows, Docker is captured into a small virtual machine. In thesecond, Docker for macOS and Windows has extended an important level ofusability and textures more like a native app.
