explaining the docker life sycle
created a diagram and explainng it :
- ## Docker Architecture Diagram u
we can see that the docker images are all can be hosted in one host machine.
this machine has its own OS and virtualization layer that allow the docker images exist - each one on its own resources.
each container has its app running on its own OS thatcan be of any kind
- Docker Workflow
the lifecycle of docker image as described in the diagram :
- created as a Dockerfile that then pushed to a version control repo
- then we build the image from Dockerfile to make sure it run in the dev env
- after making sure the image works - we push it then to docker repository
- test env will use the docker image by pulling it and then running it
- after the test approves the docker image - the production will then use it same as test - by pulling it and running it (which can be achived in 1 command : docker run)
