Containerization | Manual Deployment

Tools to start over lovely bare metal strong 💪 hardware:

• Master Brain: Kubernetes

  • Tutorials

• Containerization Runtime (Wrapper around deployable package): Docker

  • Mini-vm for saving costs no more. Don't over-think it. To construct an up and running a container

• Runtime:

  • Which will contain the deployable package that will be an executable later and will be able to serve requests upon being healthy available

• Deployable package: This part is variable over time

  • the Senior System admin [Linux Based] will need to move this one from his/her local laptop after building the latest package locally from the SCM server using specific commands and the final outcome will be a docker image, then
  • he/she has to move this image to the testing environment where Kubernetes resides 😜 then
  • run the container from this image in a healthy available state

Runtime of developed applications:

• Backend (Java, Spring-Boot): JRE

• Web Frontend (JavaScript, React): Nodejs

Hints upon Docker usage in different environments:

• Use base image wisely when writing Dockerfile, because it affects on the image building time AKA transmitting fucken bloody hell a lot of packets over the network

  • Base image selection is based on less size and effectiveness like reviews and its robustness in different environments using a registry called Docker Hub.

• Read a bit in image layers to optimize the image as much as you can (less layers is better)
