force docker-compose push/pull

Question

I have a jenkins job that builds all my docker images and pushes them to my docker hub. It then ssh to the server on which I want to deploy and runs docker-compose pull && docker-compose up.

For some reason, this mechanism is not handling changes in the dockers well. I changed one of my requirements in one of the images. I can see in jenkins that it recognized the change and did not use the cache for that stage:

Step 16/33 : RUN ldconfig
 ---> Using cache
 ---> 15284e3997f6
Step 17/33 : ADD requirements.txt requirements.txt
 ---> 1c2d81548e55
Step 18/33 : RUN pip install -r requirements.txt
 ---> Running in 679034a149d4
Collecting alembic==0.9.5 (from -r requirements.txt (line 1))

you can see here that step 16 was still using cache and step 17 did not. Which is working as expected.

I then push the images:

-------------
Publishing Images
-------------

    Pushing base (<docker-hub-server>/base:latest)...
    The push refers to repository [<docker-hub-server>/base].

After that I ssh to the server and pull the image.

The problem is that for some reason, the new image with the updated dependecies was not pushed for some reason.

I tried removing all containers and images both in the jenkins server and in the destination server.

This feels like is something is being cached incorrectly.

im looking for a solution that will force push that image to the repo, or something similar.

Edit:

more info:

The push refers to repository [<docker-hub-server>/base]

After checking in jenkins, the right image is there, but still when I push it says that all layers already exist even though Step 16, 17 were changed.

在构建docker映像时使用--no-cache选项，并检查是否可以解决问题
