CentOS 7/RHEL 7 installations broken where $releasever is '7Server' #1111

ineffyble · 2020-09-24T01:27:48Z

This is a bug report
I searched existing issues before opening this one

Expected behavior

yum install is able to install docker-ce from the repo provided at http://download.docker.com/linux/centos/docker-ce.repo when the $releasever variable is set to 7Server.

Actual behavior

At some point in the last week, this has stopped working, and https://download.docker.com/linux/centos/7Server is now a 404. I suspect this coincides with the release of the CentOS 8 packages.

https://download.docker.com/linux/centos/7 still exists, but that is not the same $releasever and so the repo reference in http://download.docker.com/linux/centos/docker-ce.repo is broken.

Steps to reproduce the behavior

Attempt to install Docker from the provided CentOS/RHEL repo with an installation of CentOS/RHEL that has 7Server set as the yum releasever.

The text was updated successfully, but these errors were encountered:

gdhgdhgdh · 2020-09-24T11:36:15Z

This broke a bunch of deployments for us and caused much yak shaving today. I'd very much appreciate the 7Server being restored.

thaJeztah · 2020-09-24T12:34:23Z

Is this both on CentOS and RHEL machines? Does CentOS also set the Server suffix?

thaJeztah · 2020-09-24T14:28:00Z

I opened a PR with a workaround for our install script docker/docker-install#194 (but for manual installations, something similar will have to be done);

If you're on RHEL7/CentOS7 and have this issue:

for channel in "stable" "test" "nightly"; do \
    yum-config-manager --setopt="docker-ce-${channel}.baseurl=https://download.docker.com/linux/centos/7/debug-\$basearch/${channel}" --save; \
    yum-config-manager --setopt="docker-ce-${channel}-debuginfo.baseurl=https://download.docker.com/linux/centos/7/debug-\$basearch/${channel}" --save; \
    yum-config-manager --setopt="docker-ce-${channel}-source.baseurl=https://download.docker.com/linux/centos/7/source/${channel}" --save; \
done

If you're on RHEL8/CentOS8 and have this issue:

for channel in "stable" "test" "nightly"; do \
    yum-config-manager --setopt="docker-ce-${channel}.baseurl=https://download.docker.com/linux/centos/8/debug-\$basearch/${channel}" --save; \
    yum-config-manager --setopt="docker-ce-${channel}-debuginfo.baseurl=https://download.docker.com/linux/centos/8/debug-\$basearch/${channel}" --save; \
    yum-config-manager --setopt="docker-ce-${channel}-source.baseurl=https://download.docker.com/linux/centos/8/source/${channel}" --save; \
done

andrewbanchich · 2020-09-25T14:40:57Z

I'm experiencing this on RHEL 7.7.

Running your workaround @thaJeztah gives me:

No package docker-ce available.
Error: Nothing to do

ghost · 2020-09-25T16:07:25Z

@andrewbanchich The work-around only works if you are using the CentOS version of Docker on RHEL. Red Hat no longer supports Docker so many people switched to using the CentOS version of Docker on RHEL.

Run the CentOS installation instructions on RHEL https://docs.docker.com/engine/install/centos/
But before you $ sudo yum install docker-ce docker-ce-cli containerd.io run the work-around.

One more thing. When switching to the Docker for CentOS watch out for #477

msbecker · 2020-09-25T17:00:28Z

I am getting the following error after running the workaround to fix the broken repo link.

@andrewbanchich I'm guessing you are stuck with RHEL 7.7 and can't switch to 7.8 for some reason, right?

andrewbanchich · 2020-09-25T17:50:03Z

@mettacrawler Correct. Actually I need to use this on 7.6, but I didn't think there would be a huge difference between dot releases.

Yeah, I had this same problem on a fresh RHEL 7.8 this afternoon. The workaround of changing the base paths resulted in

Is there an expectation that this will be fixed in the repo 'in the near term' so that these workarounds are not required?

Podman give you rootless (not using the root account to run) containers on RHEL 7 right now. Think about the security improvements. https://www.redhat.com/en/blog/rhel-78-and-final-update-container-tools
Podman works with Dockerfiles and Docker repositories, so much of the software there is available and more will be over time.
There's podman-compose intended to be much like docker-compose and it becomes even more like it over time https://github.com/containers/podman-compose
Red Hat will actually support you on Podman (they are no longer supporting Docker).
People are using Podman to do things right now. Better study it early so you're not left behind.

M0rdecay · 2020-09-28T06:33:04Z

Any news on this?
We are deploying docker via ansible, using workarounds requires changing roles, which we would like to avoid.

tonton1728 · 2020-09-28T09:17:03Z

On our side, we are building some docker image with docker inside (inception I know) and we would like not to have to edit repo file in our dockerfile.
As far as I know, creating an alias for 7Server to 7 should do the trick, when can we hope to have a fix ?

ghost · 2020-09-28T13:47:48Z

@tonton1728
When I first encountered this issue I was trying to rebuild an AWS AMI via Packer and it crashed trying to install docker-ce. The Ansible that Packer was invoking never tried to install a containerd.io RPM and it worked anyway. If all you are doing is installing a docker-ce RPM then you don't need to download a CentOS container-selinux RPM to support a containerd.io. In that case just changing the docker-ce-stable.baseurl from using $releasever to using a hard-coded 7 will work.

If you need to install a CentOS containerd.io RPM you will also need to install a CentOS container-selinux RPM and doing that is a bit messy.

Thank you @mettacrawler for the response. I will investigate Podman when I have a little breathing room.
Right now, I am not able to execute my ansible script on my hosts that are built with releasever 7.8 and need to get them working in the short term.

The fact that this isn't fixed yet makes me feel like Docker did this on purpose in retaliation to RH creating podman.

@gflcampos adding the CentOS repository may cause other RPMs to come from CentOS.

A usable version of the container-selinux RPM is available from certain RHEL and Oracle repositories. If they are available to you, you do not need to use the CentOS container-selinux RPM. You still have to use the CentOS docker-ce RPM from Docker.

First

sudo yum install -y yum-utils

For AWS see https://access.redhat.com/articles/4599971

sudo yum-config-manager --enable rhel-7-server-rhui-extras-rpms

For Azure:

sudo yum-config-manager --enable rhui-rhel-7-server-rhui-extras-rpms

For Oracle Linux 7

sudo yum-config-manager --enable ol7_addons

Then on any of them (see https://docs.docker.com/engine/install/centos/ for most of this.)

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine
sudo yum-config-manager \
     --add-repo \
     https://download.docker.com/linux/centos/docker-ce.repo
sudo yum-config-manager --setopt="docker-ce-stable.baseurl=https://download.docker.com/linux/centos/7/x86_64/stable" --save
sudo yum install -y docker-ce
sudo systemctl enable docker
sudo systemctl start docker
sudo docker run -it --name hello-world --rm hello-world

FYI, on RHEL it's rhel-7-server-extras-rpms.

It looks like the symlinks have been restored, however the webserver is now trying to serve a index.html when using the symlinked version of the url, so it doesn't look like it allows directory browsing on the symlinked URL's eg:
https://download.docker.com/linux/centos/7Server/x86_64/stable/repodata/
However when you change the URL to:
https://download.docker.com/linux/centos/7/x86_64/stable/repodata/

Using the first link you now get:
404 Not Found

bviktor · 2020-11-23T15:24:14Z

yum doesn't need to "browse" the dirs, it uses predefined files.

rabievdm · 2020-11-23T15:27:50Z

Fair, but its still broken when I trying and just do a yum list, so the perms must still be broken.

Honestly I feel it's unacceptable that this 4 months old bug is still open. How long does it takes to do a symlink or a 301 http redirect on a web server? I mean this is admin level 0, so what is the technical challenge that need to be accomplished to solve this issue? None.

Well, I feel this is the time to migrate away from Docker because all what we did is now broken (thanks by the way) and require us to workaround in the worst way. What is the point of automating everything if we can't reuse what has been done, isn't the Docker promise ? I don't feel breaking things is the correct way to do for the docker user base, but well, I feel there is a lots of politics behind this choice of not fixing this issue, and I don't feel comfortable with this anymore. Also I don't pay for any service/support so I shouldn't complain, but this bug is a very bad joke.

Pictor13 · 2021-01-10T15:56:38Z

I fixed the repo URl via:

sed -i 's/$releasever/7/g' /etc/yum.repos.d/docker-ce.repo

according to this forum thread suggestions.

Might help other fix temporary and get work done.

epijonk · 2021-02-05T09:33:50Z

lol.. still not fixed. I just ran into this error.

bitva77 · 2021-02-05T10:26:10Z

haha! what a joke.

long live containerd?!

Vaccano · 2021-02-06T01:31:59Z

Wow! Since this is apparently not going to get fixed, it desperately needs to get added to the docs. (I lost a lot of time on this.)

If the docs had just said:

There is an open issue that we are still thinking about. Until we decide to fix the redirect to work on the actual file you need, add this call before you run yum install :

sudo yum-config-manager --setopt="docker-ce-stable.baseurl=https://download.docker.com/linux/centos/7/x86_64/stable" --save

(Tongue and cheek added since this is kind of depressing to have a redirect cause so much sadness.)

chainhead · 2021-03-24T11:37:26Z

@Vaccano
You have a space between download and .docker.com in value of docker-ce-stable.baseurl.

Fast forward to Mar '21, this problem still exists. I am trying to install docker on an Amazon Linux 2 EC2 instance - which, I believe, is RHEL 7. And, this is what I see after doing the yum-config-manager.

sudo yum install docker-ce docker-ce-cli containerd.io -y

denven · 2021-03-25T09:42:04Z

I got this error and come here, after fixing the broken repo, I got some other dependencies error afterward. Anyway, I installed it finally. If you failed to install docker on Oracle Linux 7.9 or CentOS 7.x ( coz they are alike), check this link:

I wrote a script here, you can use the bash script to install it.

chaseduffin · 2021-04-14T20:35:35Z

Still a problem. wtf @docker

thaJeztah · 2021-04-15T12:23:46Z

@chaseduffin I think fixes were made for this; are you still running into this issue? What $releaseVer does your machine have?

I just tried to reproduce the problem (quick check in a container);

docker run -it --rm centos:7

Add the repository;

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Set 7Server as $releasever to mimic the scenario reported here:

for channel in "stable" "test" "nightly"; do \
    relver=7Server; \
    yum-config-manager --setopt="docker-ce-${channel}.baseurl=https://download.docker.com/linux/centos/$relver/\$basearch/${channel}" --save; \
    yum-config-manager --setopt="docker-ce-${channel}-debuginfo.baseurl=https://download.docker.com/linux/centos/$relver/debug-\$basearch/${channel}" --save; \
    yum-config-manager --setopt="docker-ce-${channel}-source.baseurl=https://download.docker.com/linux/centos/$relver/source/${channel}" --save; \
done

Verify that that worked correct, and that the repository now has 7Server in its repo-URL:

yum repolist -v docker-ce-stable

creatorKoo · 2021-04-15T23:52:02Z

@docker guys should feel ashamed that this bug has been open for 4 months. Who is in charge of this issue?

I got little solution about 404.

sudo rm -rf /var/cache/yum/x86_64/7/docker-ce*
yum update
yum install docker-ce

then work for me.

thaJeztah · 2021-06-02T14:32:01Z

closing as this should be fixed #1111 (comment)

rindeastwood · 2021-06-11T09:21:00Z

Issue still exists on CentOS 8. (CentOS Linux release 8.4.2105)

msbecker · 2021-06-11T15:08:02Z

Given the switch to CentOS Stream, I suspect this may not ever be fixed, at least not soon.

thaJeztah · 2021-06-11T15:14:55Z

@rindeastwood what does yum repolist -v docker-ce-stable show for you? That URL it's trying to download looks really wrong (https://download.docker.com/linux/centos/docker-ce.repo is a file)

johntiger1 · 2021-07-07T20:47:20Z

Still broken for me.

worked for me

thaJeztah · 2021-07-07T21:41:39Z

@johntiger1 we currently don't have packages for Amazon Linux on download.docker.com, so that's somewhat expected (but good to hear the workaround worked)

jamshid · 2023-09-18T15:00:30Z

NEVERMIND THE REPO FILE IS WORKING NOW.

@thaJeztah this repo file is empty, I assume it should not be. It's causing No package docker-ce-cli available..
