Unable to find docker image locally

Question

I was following this post - the reference code is on GitHub. I have cloned the repository on my local.

The project has got a react app inside it. I'm trying to run it on my local following step 7 on the same post:

docker run -p 8080:80 shakyshane/cra-docker

This returns:

Unable to find image 'shakyshane/cra-docker:latest' locally
docker: Error response from daemon: pull access denied for shakyshane/cra-docker, repository does not exist or may require 'docker login'.
See 'docker run --help'.

I tried login to docker again but looks like since it belongs to @shakyShane I cannot access it.

I idiotically tried npm start too but it's not a simple react app running on node - it's in the container and containers are not controlled by npm

Looks like docker pull shakyshane/cra-docker:latest throws this:

Error response from daemon: pull access denied for shakyshane/cra-docker, repository does not exist or may require 'docker login'

So the question is how do I run this docker image on my local mac machine?

Answer 1

Well this is anti-logical but still sharing so future people like me don't get stuck

So the problem was that I was trying to run a docker image which doesn't exist.

I needed to build the image:

docker build . -t xameeramir/cra-docker

And then run it:

docker run -p 8080:80 xameeramir/cra-docker

Answer 2

In my case, my image had TAG specified with it and I was not using it.

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
testimage          testtag            189b7354c60a        13 hours ago        88.3MB

Unable to find image 'testimage:latest' locally for this command docker run testimage

So specifying tag like this - docker run testimage:testtag worked for me

Answer 3

Posting my solution since non of the above worked. Working on macbook M1 pro.

The issue I had is that the image was built as arm/64. And I was running the command:

docker run --platform=linux/amd64 ...

So I had to build the image for amd/64 platform in order to run it.

Command below:

docker buildx build --platform=linux/amd64 ...

In conclusion your docker image platform and docker run platform needs to be the same from what I experienced.

Answer 4

In my case, the docker image did exist on the system and still I couldn't run the container locally, so I used the exact image ID instead of image name and tag, like this:

docker run myContainer c29150c8588e
