I created an image for my application and uploaded it as private repository in registry.hub.docker.
Now I every time I try to pull it, I get the following error
FATA[0012] Repository not found
I have successfully authenticated myself with docker using docker login command
Command I ran
## docker login
docker login
Username (werain): werain
WARNING: login credentials saved in /Users/werain/.dockercfg.
Login Succeeded
## docker pull
docker pull werain/digitdem
Any Clue?
Use the full image name, including the tag, when pushing and pulling:
docker push werain/digitdem:latest
docker pull werain/digitdem:latest
Docker generally assumes you mean latest when you don't specify, but if you want to use your own tag or if you didn't push the same tag as you're trying to pull, then omitting the tag won't work.
Add .netrc file to the dockerfile will pass credentials inside the docker containers and helps to pull more than one private repositories to build dependencies
#vim .netrc
machine github.com
login < your github token >
Add those 2 lines and pass your github token
Then copy the .netrc file to the container by including this line
COPY .netrc /root/

Since Docker Hub only allows 1 private repo, I wonder if there is any way to use Github or Gitlab, etc., to download the images? for instance:
FROM git#github.com/username/repo
...
...
...
Very easy with an account on gitlab.com. GitLab provides a Docker registry linked to projects and you can have unlimited private projects:
Create a project my-docker-project
Go to Package and Registries > Container registries, you should see a few commands to access your registry
Connect your machine to this registry using a command like:
# Will prompt for login/pass
docker login registry.gitlab.com
You'll need an access token or deploy token with read_registry and write_registry scopes. You can generate one via your profile Preferences > Access token. Login is the token name and password the secret token provided.
You can now push Docker images with commands such as:
# Push an image
docker push registry.gitlab.com/YourUsernameOrGroup/my-docker-project
# Push an image on a sub-path
docker push registry.gitlab.com/YourUsernameOrGroup/my-docker-project/myimage
You can then use the image in a Dockerfile by referencing its URL such as:
FROM registry.gitlab.com/YourUsernameOrGroup/my-docker-project
# ...
Of course the machine from which you build must be authenticated on related GitLab registry using docker login command above (or the project must be public)
both have excellent package registry services
For GitHub GPR
For GitLab GCR
Both have excellent features like use it directly from Dockerfile as you want for example.
I have a public example, you can check it in Github with node.js which uses GPR to store the build image/package.
I need to deploy selenium/standalone-chrome image to docker.
The problem is that I use corporative openshift with private registry. There is no possibility to upload image to registry or load it thru the docker (docker service is not exposed).
I managed to export tar file from local machine using command 'docker save -o'. I uploaded this image to artifactory as an artifact and now can download it.
Question: how can I create or import image based on a binary archive with layers?
Thanks in advance.
Even you're using OpenShift, you can proceed to Docker push since the registry is exposed by default: you need your username (oc whoami) along with the token oc whoami --show-token.
Before proceeding, make sure you have an Image Stream since it's mandatory in order to push images.
Once obtained these data, proceed to login from your host:
docker login -u `oc whoami` -p `oc whoami --show-token` registry.your.openshift.fqdn.tld:443
Now, you just need to build your image
docker build . -t registry.your.openshift.fqdn.tld:443/your-image-stream/image-name:version
Finally, push it!
docker push registry.your.openshift.fqdn.tld:443/your-image-stream/image-name:version
I am trying to create a docker image using the below command .
docker build -t mytestapp .
My DockerFile looks like this
# Set the base image
FROM rhel7:latest
USER root
# Dockerfile author / maintainer
MAINTAINER Name <email.id#example.com>
# Update application repository list and install the Redis server.
RUN mkdir /usr/local/myapp/
ADD myapp-0.0.1-jar /usr/local/myapp/
RUN java -Dspring.profiles.active=qa -jar /usr/local/myapp/myapp-0.0.1.jar
# Expose default port
EXPOSE 8080
Questions:
1) Is it fine the way I am adding the JAR file. Will it be available inside /usr/local on the container after I prepared am image from the above build.
2) When I build the image using docker build command , is the build image is pushed to docker repository hub by default.
Since the WAR file contains credentials, I don't want to push the image to Docker Hub but we would like to push to our local Docker registry using Docker distribution and pushing with docker push.
Please clarify.
Answering your questions:
Docker recommends using the COPY instructions for adding single files into an image. It will be available inside the container at /usr/local/myapp/myapp-0.0.1-jar
When you build the image it will be available on your local docker-host. It won't leave the server unless you explicitly tell it so.
Another tip I want to give you is the recommended docker image naming convention, which is [Repository/Author]/[Imagename]:[Version].
So for your image it might be called zama/mytestapp:1.0
If you want to push it into your local registry, you'll have to name your image after the syntax [LocalRegistry:Port]/[Repository/Author]/[Imagename]:[Version].
So your image might now be called registry.example.com:5000/zama/mystestapp:1.0
If you have authentication on your registry, you need to docker login first and then simply push the image with docker push registry.example.com:5000/zama/mystestapp:1.0.
I created a docker image and pushed to docker hub, then i changed it to private.
In my Mac, I can pull it after I issued "docker login" and entered all the info.
But in Cento7 (VM), this is no longer working, the private repository can not be found. I have to change the repo from private to public, then I can pull the image.
Why this happened? What do I need to do in order to pull a private repository from docker hub?
Thanks
create a new file .netrc to
#vim .netrc
machine github.com
login < your github token >
Add those 2 lines and pass your github token
Then copy the .netrc file to the container by including this line in dockerfile will pass credentials inside the docker containers and helps to pull more than one private repositories
COPY .netrc /root/
So im trying to pull a fresh repository from docker, wich it seems to be pretty easy but i just can't.
Im seeing this (check image)
but im getting "repository not found", this is what im running.
bash-3.2$ docker pull ethaan/test
Pulling repository ethaan/test
Repository not found
bash-3.2$
Also im trying with Kitematic, but its kinda the same, here are som ss from kitmatic.
First the "my repos view"
Now when i click on "create", i got this error.
UPDATE
Updating Start Repository email image
Update view from docker hub enterprise
If this is a private repository (it doesn't exist from my view), you will need to login first.
https://docs.docker.com/reference/commandline/login/
Usage: docker login [OPTIONS] [SERVER]
Register or log in to a Docker registry server, if no server is
specified "https://index.docker.io/v1/" is the default.
-e, --email="" Email
-p, --password="" Password
-u, --username="" Username
You are not able to pull it because you just don't have any tags in ethaan/test. That is, the repository is empty. Once you push a tag, you will be able to pull it. Just to test, try the following:
docker pull busybox
docker tag busybox ethaan/test:test
docker push ethaan/test:test
Then you will be able to pull it as:
docker pull ethaan/test:test
