Docker - What is proper way to rebuild and push updated image to docker cloud?
I meet the problem as well(In my web application
), like this:
# when I push my contaimer to repo
$ docker push <container>
The push refers to repository [docker.io/xx/getting-started]
fd5aa641b308: Layer already exists
d9c60c6f98e8: Layer already exists
d9d14867f6d7: Layer already exists
64ce166099ca: Layer already exists
73b670e35c69: Layer already exists
5f70bf18a086: Layer already exists
9ea142d097a5: Layer already exists
52f5845b1de0: Layer already exists
I try my Solution, and it's works!
# force remove image
$ docker rmi --force <image-id>
# tag for image
$ docker tag <image-name> <your-dockerHub-username>/<image-name>
# push image, just done!
$ docker push <your-user-name>/<image-name>
terminal output:
# when I push my container to repo
$ docker push <container>
The push refers to repository [docker.io/xx/getting-started]
# it'll push your part of changes
fd5aa641b308: Pushed
d9c60c6f98e8: Pushed
d9d14867f6d7: Layer already exists
64ce166099ca: Layer already exists
73b670e35c69: Layer already exists
5f70bf18a086: Layer already exists
9ea142d097a5: Layer already exists
52f5845b1de0: Layer already exists
Then, open my web appliction
, it's updates the lastest version!
I found the problem, thanks to @lorenzvth7!
I've had two images with same tag (which i was pushing to cloud).
Solution is:
Inspect your images and find two or more with the same tag:
docker images
Delete them:
docker rmi --force 'image id'
- Thats it! Follow steps from my question above.
Another solution, albeit bruteforce, is to rebuild with the --no-cache flag before pushing again.
docker rmi --force my-djnago-app:latest
docker build -t my-djnago-app:latest . --no-cache
docker push my-djnago-app:latest
