I'm new to docker and trying to learn how to push and pull. I've been stuck with this problem for a while. I'm trying to push and image to my docker, but keep getting the same error "Invalid reference format" see picture for details.
Before pushing the local image to the repository, you should tag the image with the repository url:
docker tag staticwebserver:v1 <registry-url/repository>staticwebserver:v1
Then you push the tagged image:
docker push <registry-url/repository>staticwebserver:v1
Remove the [], it should be staticwebserver:v1. Docker doesn't understand the format which you are trying to use/post with the registry.

I am looking for Containerfile or Dockerfile for container-registry.oracle.com/middleware/webtier image. I need to see how Oracle builds its webtier container image. I have tried
podman inspect container-registry.oracle.com/middleware/webtier:latest
and it gives bunch of info but it is difficult for me to have whole pic. Please let me know where I can find this file.
I found oracle repo on github and following is the URL for ohs 12.2.1.3.0 docker image dockerfile. https://github.com/oracle/docker-images/blob/main/OracleHTTPServer/dockerfiles/12.2.1.3.0/Dockerfile
If I run the 'docker pull' command to pull an image directly from docker hub, it works fine.
But when I pull the image via Artifactory, i.e. with docker hub as the remote repository, then I got this error:
Error response from daemon: manifest for //image1:1.0.0 not found: manifest unknown: The named manifest is not known to the registry.
Another note is, if the image doesn't have the "image path", it works fine.
What is going wrong here? Thanks for your help!
Maybe repo is empty. Check on dockerhub
I am trying to build an image with a base image from our internal Artifactory registry and trying to push it with a new tag. The docker is able to push all the layers except for the manifest file and gives below error:

I am using Docker BuildKit to generate my image and the push is done with docker push <imagename:tag> in Jenkins. Our previous version of code was using docker python package and with that, we can still build the image and push it to our internal registry.
I don't know how to change the Manifest version 2, schema 1 to versions, schema 2 using Docker BuildKit.
Help me, please!
I have an app with a Dockerfile content that looks like
Dockerfile
FROM SOME_NUMBERS.dkr.ecr.us-east-1.amazonaws.com/app_name:SOME_HEX_VALUE
COPY docker/app/bin/startup.sh /usr/bin/
CMD ["/usr/bin/startup.sh"]
I don't want to pull the image from amazon anymore instead I'd like to "pull" from the already-existing local image pulled the after the first docker-compose up --build command was ran.
When I do docker images I get
SOME_NUMBERS.dkr.ecr.us-east-1.amazonaws.com/app_name SOME_HEX_VALUE SOMESHORT_HEX 2 days ago 1.54 GB which means the image is local already. I understand this
if the host has the image you want docker-compose to use on it it will use that image but if the host doesn't have it, it will go to docker hub or whatever you have setup in your config for registries
So I changed the Dockerfile content to this:
FROM IMAGE_ID:SOME_HEX_VALUE where IMAGE_ID is the image id of the repository I want when I do docker images but then I get Service 'app' failed to build: repository SOMESHORT_HEX not found: does not exist or no pull access and I'd like to know how to tell Docker to use the local image instead of trying to pull from the amazon url. Any ideas?
First pull the images from the remote repository in your local Docker engine:
docker pull SOME_NUMBERS.dkr.ecr.us-east-1.amazonaws.com/app_name:SOME_HEX_VALUE
Now, give the image a new local tag:
docker tag SOME_NUMBERS.dkr.ecr.us-east-1.amazonaws.com/app_name:SOME_HEX_VALUE my-image-name
Now you can simply refer to my-image-name, as in:
FROM my-image-name
You should:
FROM IMAGE_ID
Or, this is already ok:
FROM SOME_NUMBERS.dkr.ecr.us-east-1.amazonaws.com/app_name:SOME_HEX_VALUE
Where SOME_HEX_VALUE is the tag version (the second column in docker images). Note that if the images is present in your computer, docker won't try to pull it again.
System info :
RHEL 7.1 (fresh install)
Docker 1.6.2
We're using the Docker rpm provided by RH in their "bonus" dvd's.
Issue :
When I pull an image through docker, it only works when it's on the Red Hat repo.

When I pull an image from Docker repo... it fails. But - which is imho really weird - with different errors.
So first I pull httpd

I'm on a corporate network and applied what's in this blog concerning proxies and certificate to get it running.
service docker stop
rm -r /var/lib/docker/*
service docker start
Worked for me. Note that this will very likely clear docker
There are couple of things you can do to mitigate this :
If you're seeing this error while pulling large images from private
repo, It could mean that the private repo is busy, as someone else
might be pulling at the same time.
If the size of the image which you're pulling is huge and your machine is under-powered you still
could see this issue, even though you could be pulling from a public
repo.
If none of the above applies to you, then I think you've hit a
strange bug in docker 1.7, Your best bet is to upgrade the client
version to 1.11 or recent.
I also received unexpected EOF when pulling a large image (>2GB). However, the answer for us was to increase the size of the file system where the incoming images were being cached before being moved on to where the docker daemon stored them.
Sounds irrelevant to the real issue of this question but it might be useful for someone else to check in future.
