Packing an image, from existing docker containers

[Ori N]

Hello,

I have several containers, which build together an application with http access.

I want to be able to pack this application as an image. What I thought is to use packer to:

• Install OS and docker
• Pull container images from my own private repository
• Run the containers using docker CLI commands

I wanted to get feedback about it. Is it the right way to go?

Thanks,

Ori

if you have an existing image then you don't need packer at all

you can use docker commands like docker image save

https://docs.docker.com/engine/reference/commandline/image_save/

packer is a tool that can be used to create docker containers. but if you have those then not sure what would be the benefit of having packer in the middle

can you explain more?

My target is to have an image (like for example AWS AMI) and not a docker image. 

The image I'm talking about has a full app, with multiple containers, network and so on. I want to be able to pack the entire thing as an image.

My process for example is the following:

docker images + scripts -> AWS AMI
