[Day 18] Cloud Playing With Containers | Advent of Cyber 3 (2021)

Docker? Yapp.
Today we will be learning about Container and Docker. Docker is another way to make an instance like virtualization, but not like VM.

VM vs Docker

Some people say that Docker is more efficient than Virtual Machines (VMs) but it depends on what you need.

Let’s hack the docker..

# What command will list container images stored in your local container registry?

docker images

# What command will allow you to save a docker image as a tar archive?

docker save

# What is the name of the file (including file extension) for the configuration, repository tags, and layer hash values stored in a container image?

manifest.json

# What is the token value you found for the bonus challenge?

Some settings will be saved in the config file, so dive into it.

Try to search config file and use the powerful tool from Linux, grep command.
