Dockerization, also known as “containerization,” refers to the process of packaging an application and its dependencies into a standardized container called a “Docker container.” Docker is an open-source platform that provides a lightweight and isolated environment for running applications.
-
Verify that the Docker Engine installation is successful by running the hello-world image.
sudo docker run hello-world
-
Containerizing app
docker build -t package-name . -
Running the image
sudo docker run -it -p 8000:8000 package-name
It will map 8000 port of container image to 8000 port of my machine
- On AWS ERC we will create repo
