Issue
I have a project which consists of several services which are defined in a docker-compose.yaml file.
When I run docker-compose up -d several docker images are created and then each service runs in its own container.
I have followed the steps here How to save all Docker images and copy to another machine in order to save the images so that I can use them on another customer PC.
I ran this to save the images:
sudo docker save $(sudo docker images | sed '1d' | awk '{print $1 ":" $2 }') -o my_project.tar
And I can load this by doing:
sudo docker load -i my_project.tar
This appears to have saved and loaded the images as I check with the following command and all the imaegs do appear with the correct names and tags:
sudo docker images
But at this point there are no contianers running. How do I actually start each container the same way they were started with the docker-compose up command when using the original project?
Solution
The important part of this is that you must have copy the docker-compose.yml file to the target system.
So you need two things
1: tar file having multiple images
2: docker-compose file to describe how each image should load.
