Run docker compose file without internet connection

Question

I have a .NET project with docker support, so I run docker-compose.yml with docker-compose.override.yml file - Windows OS with Linux docker containers.

My idea is to download all necessary images and then run that same docker-compose file without internet connection. So, i will have connection initially, download all the images, and then go offline and run the app.

Any idea how can I do that?

Answer 1

Do below steps

• First over the internet get to build all required docker images.

• Then save/export those images in the tar file by using below command

  docker save image_name > /image/mynewimage.tar

• The go offline, copy those tar file on another or same machine and load those images by using below command

  docker load < /image/mynewimage.tar

• Then run normal docker run commands, you already have got all images locally hence docker will not try to get it download from the internet.

This should work, let me know if you need any help with this.

Please post your docker-compose file, if in case of any issue with above approach.
