I'm trying to download a tagged docker image
docker pull clkao/postgres-plv8:10-2
and, in a compose file,
postgres:
image: clkao/postgres-plv8:10-2
But receive a manifest not found exception.
Unless I'm mistaken, that tag exists in Docker Hub, however I notice that it doesn't appear on the tags list.
Am I doing something wrong? Or is this perhaps an issue with Docker Hub or the way that repo has been set up?
If it isn't 'my fault', what's a recommendation to move forward? Create my own Dockerfile perhaps?
You might also try
docker pull -a <image>.
The -a will pull all versions of that image, which at least lets you know what is there.
(This is less useful if you really need a specific version, but helped me when I tried to pull an image that for some reason did not have a 'latest' tag.)
Edit: This is actually a really bad idea, since it will pull down the entire history, which for many repositories could be many GB. Better to go look at the repository site and see what tag you want. Note to self: don't post answers when you are tired. :-(
You get the error message because there exist no tag with "10-2".
You can try to figure out why and contact the repository owner or you can try to build your own one.
I just got over this "manifest for / not found: manifest unknown: The named manifest is not known to the registry."
Using
docker login <repo>
Check the docker's image also not only that the tag exists, I was trying to run Flyway version 5.0.1 for an image flyway/flyway which version did not exist, it existed only in version flyway/flyway:latest it seems, whereas 5.0.1 existed and I pulled it but in/from a different repository name, with repository name boxfuse/flyway.
for the error message 'docker manifest unknown'
When you use docker pull, without a tag, it will default to the tag :latest. Make sure that when we are building a image add tag latest or we can access the image by the tag name after image name with colon
I think you are trying to tag your image as v8.10.2. Make sure while tagging image locally you use same tag which you want to pull in future. So steps will be like below:
docker build -t clkao/postgres-pl:v8.10.2 .
docker push clkao/postgres-pl:v8.10.2
docker pull clkao/postgres-pl:v8.10.2
If this is from Git via docker.pkg.github.com then you need to switch to use ghcr.io. The former is deprecated and does not support the manifest endpoint so some docker clients, when they attempt to download various resources, fail with this error message. If you instead publish your image to ghcr (Github Container Repository), the docker image pulling process should complete successfully.
cd <dir with Dockerfile in it>
docker build -f Dockerfile -t ghcr.io/<org_id>/<project_id>:<version> .
docker push ghcr.io/<org_id>/<project_id>:<version>

I'm trying to run the docker pull ibmblockchain/fabric-peer command, but I'm getting this error message:
Error response from daemon: manifest for ibmblockchain/fabric-peer:latest not found.
Is there any other way to pull this image ? Also trying to pull another images but get same error message.
As you can see on below link the tag is not available
https://hub.docker.com/r/ibmblockchain/fabric-peer/tags/
You should use 1.0.1
docker pull ibmblockchain/fabric-peer:1.0.1
If you're not specifying the tag then docker will download the latest tag by default.
This error may occur if the latest tag is not attached to the latest version of the image.
To solve the problem
Visit https://hub.docker.com/ and search your image.
Find the latest tag and copy
Pull image with the tag.
Example:
To install Jenkins, instead of running
docker pull jenkins
I would do
docker pull jenkins:2.60.3
Thanks
I got the same error message when I tried to pull the image from hub.docker.com. Not this image but another. This error was related with the tag version. In my case, I push the V0.6 version and I was trying pull v0.6 version. Note that I used the upper case to write the "V" and I was trying the lower case "v". So, the tag image is really not found.
I hope this help anyone.
I recently ran into this problem on windows, and realised it was because I had my docker daemon running Windows containers, this meant that the host architecture isn't a match for the architecture tags on most images. Once I switched to Linux containers all started working again.
i was also facing the same issue. Tarun's answer is correct. All you have to do is
open docker-compose.yml file and add hyperledger/fabric-peer:x86_64-1.0.2 or whichever you are pulling.
close the file and run the docker-compose up command.
This means the image that you are trying to pull does not exist, check the image tag or the URL that you are specifying.
There has one image and it is public in my dockerhub account
I have logged in from my console then try following command but not able to pull the image
rajarshi#rajarshi-X200CA:~$ sudo docker pull rajcybage/tomcat8_rajarshidd
Using default tag: latest
Pulling repository docker.io/rajcybage/tomcat8_rajarshidd
Tag latest not found in repository docker.io/rajcybage/tomcat8_rajarshidd
Any help would really appreciable
Thanks in advance
If you search Docker Hub for tomcat8_rajarshidd, you can find its page, then click the tags tab to view available tags.
At the time of this writing, the only available tag is 2. As the error told you, there is no latest tag available.
So all you need to do is use a valid tag. There's only one you can use in this case:
docker pull rajcybage/tomcat8_rajarshidd:2
If this is your image, you can create a latest tag easily.
docker tag <image-id> rajcybage/tomcat8_rajarshidd:latest
docker push rajcybage/tomcat8_rajarshidd:latest
This would not push any new layers, as the layers are already present on Docker Hub, but it would attach the latest tag to this image.
We have been using locked version of the Minio image (RELEASE.2016-10-07T01-16-39Z), but now it seems to have been removed.
I'm getting this from Docker:
Pulling minio (minio/minio:RELEASE.2016-10-07T01-16-39Z)...
Pulling repository docker.io/minio/minio
ERROR: Tag RELEASE.2016-10-07T01-16-39Z not found in repository docker.io/minio/minio
I'm finding Docker hub hard to navigate. Where can I find a list of available versioned images, or a mirror to my exact image?
You can find the available tags for minio/minio on that repository's tag page.
If you have the image you want already downloaded on any of your systems, you can push it to Docker Hub yourself, then pull it onto your other systems. This has the benefit that you can control whether you delete that image (it's your account, not someone else's).
You can also use a private registry, if you want, which would prevent Docker from deleting the image from Docker Hub against your will for some reason. But that is extra work you may not wish to do (you would have to host the registry yourself, set it up, maintain it...)
We removed the docker version due to incompatibilities, from the recent releases it won't happen.
One can easily build docker images through docker build command.
What I'm wondering is the t flag that you can give when building the image. For example:
$ docker build -t ouruser/sinatra:v2 .
According to documentation, the t flag is for tagging and naming purposes. Name is the part before ':', and tag is the part after it. So in our example, the name is ouruser/sinatra, and the tag is v2.
I thought this would be the image name and tag. But apparently, the name is actually some repository name? Why do I think it is? Well, because if you would after this list the images with command:
docker images
You would get a listing like this:
REPOSITORY TAG IMAGE ID CREATED SIZE
ouruser/sinatra latest 5db5f8471261 11 hours ago 446.7 M
Bang! Major shock! You thought you were creating an image with name, and instead, you specified some repository! Related to this, I have some questions:
Where is this repository located?
Can I name the image without creating a repository?
Where and how is this repository used, or could be used?
Where can I find more information about this repository? I only found this, and it doesn't tell much to be honest: docker build docs
Why is it common to use names that consist of two parts like this: somename/someothername?
Thank you for your help!
I believe the confusion here is the word "repository." In Docker, a repository is any group of builds of an image with the same name, and potentially multiple tags. A "registry" server, like hub.docker.com or your own private registry, holds multiple repositories, e.g. the redis repository on the public registry. That one repository has multiple tags for different versions of the build.
So with that background, to answer your questions:
ouruser/sinatra is located on your local Docker host until you do a docker push
No, the repository and the tag is the name of the image.
While local on your system, you can use this image locally. Once you push it up to a registry, you can then pull it down to any other Docker host that has access to that registry. And if you do a docker save you can save that image for a docker load on another host.
I'm sure there is documentation covering this somewhere on docs.docker.com, but I learned from a class.
The username/imagebase format came about to support pushing to your own namespace in hub.docker.com. Without that, whoever makes the first "Redis" image calls it "redis" while the next person makes their own repository called "redis-improved", and we quickly get into a jumble of confusing names where it's not clear who made what and what is a reputable image. That naming isn't required for images you make locally, but is still encouraged since images you pull from hub.docker.com may lack a username if they are maintained by Docker themselves. Without your username, you won't know which images you pulled down and which you built yourself.
I was using centos image from https://registry.hub.docker.com/u/blalor/centos/
For some reason Blalor decided to remove passwd from the list of packages installed on the base image and my dockers stopped working on new deployments. Why does not docker know the build which was used for my dockers? I have had to change my base images now and change every server's docker image.
I could not use the tag feature because there is the tagging for the blalor's images? Do I have to use the source code and host the centos image myself so that it does not change again?
You do not need to use sources. If you have a working image, you can do docker history <your image> to see the image ID that was used and tag the proper one into shortfellow/centos. If you do not have a working image, on the link you provided, there is a build detail section with the history of build. You can see that on January 13th, 2014, it has been built and the image then was a531daec9f98. You can do FROM a531daec9f98 on your dockerfile to make sure it will never change or you can docker tag a531daec9f98 shortfellow/centos (you will need to docker pull a531daec9f98 before).
It is very similar to git in a sense that if you are using someone's repository, and if that someone does not use tags or branches, when he updates his reposiroty and you re pull, you will have the latest version with the new changes. In order to get back to the version you liked, you need to find the commit id. The solution would be to fork the repository. Which you can do on Docker by tagging the image under you username and pushing to a registry (docker push username/image)
