I would like to use --pull always policy with docker run:
docker run --pull always url/to/remote/container
This works fine until I want to use a locally built image, but with the same command:
docker run --pull always local_container
Then I get an error:
docker: Error response from daemon: pull access denied for local_container, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.
How can I use the same command, while ignoring the --pull for locally built containers?Only option I can think of is to push the locally built container to a remote registry before pulling.

i am new to docker. i want to share a volume with multiple containers which are existing previously in my local pc not in the docker hub.
when i am using the command "sudo docker run -i -t --mount source=volume,target=/volume-shared ubuntu20", this is coming error as below.
Unable to find image 'ubuntu20:latest' locally
docker: Error response from daemon: pull access denied for ubuntu20, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.
here ubuntu20 is the container name.
can anyone help.
Thanks in advance.
You need to create volume with mount point on folder you want, and then just mount volume to container.
Check this:

I found this cheatsheet from internet: https://design.jboss.org/redhatdeveloper/marketing/docker_cheatsheet/cheatsheet/images/docker_cheatsheet_r3v2.pdf
I catch error
C:\Users\Administrator>docker run -it rhel7/rhel bash
Unable to find image 'rhel7/rhel:latest' locally
docker: Error response from daemon: pull access denied for rhel7/rhel, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.

How to fix it?
Well, this error means that the docker image you are trying to pull is private. Only logged user with permissions may pull the image. You may use the command docker login in order to login to docker hub, but if your user does not have the permissions, it will fail anyway.
This document seems to be an internal document of Red Hat. REHL is not a community distribution and there's no image for it in docker hub. You need to use one of the CentOS images instead or try other GNU/Linux distros such as Ubuntu or Debian.
In my case was an error in command.
I have tried to execute this:
sudo docker run -dit --name ${CI_PROJECT_PATH_SLUG} -p "443:443" -p "8050:8050" -p "8069:8069" -p "8052:8052" -p "3306:3306" -p "5432:5432" -p "9003:9003" linux
This param ${CI_PROJECT_PATH_SLUG} was not identified.
It looks wierd because the output is not telling the param is not recognized but this:
docker: Error response from daemon: pull access denied for 443, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
One of the universal error might not be login, you are probably pulling an image that is not in your local machine, or in the community docker hub. go to the dockerhub online and check if such image exist. If it does, then it definitely Login. These are the only possible issues one can face.
I am using docker in Linux ol7. I have installed a docker successfully. But when I try to pull images from the docker hub I am getting the below error.
[root#xxxxx ~]# docker run hello-world
Unable to find image 'hello-world: latest' locally
docker: error during connect: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.39/images/create?fromImage=hello-world&tag=latest: EOF.
See 'docker run --help'.
Docker Version I am using - Docker version 18.09.1-ol, build e32a1bd
Try to pass to full docker registry offical URL, from the error it seems like it looking on host machine Docker socket docker.sock or somewhere else but not on offical registry.
docker run registry.hub.docker.com/library/hello-world
You can explore this and this to deal with registry url.
docker run -p 8086:8086 --name users-mysql --link mysql-standalone:mysql -d users-mysql
Unable to find image users-mysql:latest locally
docker:
Error response from daemon: pull access denied for users-mysql, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.
The message means that it couldn't find the users-mysql:latest docker image in your local registry neither in the public one. Did you built the image by yourself or you want to use existing one from public repo?
If you want to use the image from public repo don't forget to use the whole name even with the prefix. List of images in public repo: https://hub.docker.com/search?q=users-mysql&type=image
If you built the image by yourself check by docker image ls the image is really present on your local. It could happen that it has a different tag than latest or you set some prefix there.
I'm getting possibly incorrect behavior and a bad error message if I run an image if a linked container is not found:
# this works:
> docker run --rm -d --name natsserver nats
> docker run --rm -it --name hello-world --link natsserver hello-world
# now stop natsserver again...
> docker stop natsserver
When I run hello-world again with the same command, I don't understand the first part of the error handling - why does docker try to pull?
> docker run --rm -it --name hello-world --link natsserver hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
Digest: sha256:b8ba256769a0ac28dd126d584e0a2011cd2877f3f76e093a7ae560f2a5301c00
Status: Image is up to date for hello-world:latest
docker: Error response from daemon: could not get container for natsserver: No such container: natsserver.
See 'docker run --help'.
And things get even worse if I try to run an image I have built locally:
> docker build -t nats-logger .
[...]
Successfully tagged nats-logger:latest
> docker run --rm -it --name nats-logger --link=natsserver nats-logger
Unable to find image 'nats-logger:latest' locally
docker: Error response from daemon: pull access denied for nats-logger, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.
See 'docker run --help'.
So my questions are:
a) Is docker allowed to try to pull in this case, or is this a bad behavior?
b) Is this really a bad error message, or did I miss something?
P.S.: I'm running Docker version 19.03.2, build 6a30dfc on Windows 10.
Is docker allowed to try to pull in this case
Docker will pull image if it is not available on the machine.
Unable to find image 'hello-world:latest' locally
This warning message is not due to linking, it is because hello-world:latest is not exist in your system local images. so whe run docker run it will look on local then will pull from remote if not exist.
Now First thing, Better to use docker-compose instead of Legacy container links.
You can not link the container if it's not running. verify the container natsserver using docker ps and then if it is running then you can link.
docker run --rm -it --name hello-world --link natsserver:my_natserver_host hello-world
Once up you can then check the linking.
docker inspect hello-world | grep -A 1 Links
Legacy container links
Warning: The --link flag is a legacy feature of Docker. It may
eventually be removed. Unless you absolutely need to continue using
it, we recommend that you use user-defined networks to facilitate
communication between two containers instead of using --link. One
feature that user-defined networks do not support that you can do with
--link is sharing environment variables between containers. However, you can use other mechanisms such as volumes to share environment
variables between containers in a more controlled way.
simply try "docker login".
check if your image name is exist in docker hub
and check correct docker build command -> docker build -t image-name .
review the correctness of Docker file script
