Ubuntu 22.04 LTS

Farhan_Ahmed · May 26, 2022, 11:08pm

Hi,

I tried to install Rancher as standalone docker but it is not starting. It seems 2.6.5 is not support on Ubuntu 22.04 LTS. I can run this on RHEL 7.9 though.

OS: Ubuntu 22.04 LTS

Rancher Docker: rancher/rancher:latest

Command: docker run -d --restart=unless-stopped --privileged -p 8080:80 -p 8443:443 -v /usr/local/share/ca_certs.crt:/etc/pki/trust/anchors/tls-ca-bundle.pem -e CATTLE_SYSTEM_DEFAULT_REGISTRY=test -e CATTLE_SYSTEM_CATALOG=bundled test/rancher/rancher:latest

2022/05/26 08:26:12 [INFO] Waiting for server to become available: Get “https://127.0.0.1:6444/version?timeout=15m0s”: dial tcp 127.0.0.1:6444: connect: connection refused

I just tested and it’s not working either…
Here is the system:

cat /etc/os-release
PRETTY_NAME="Ubuntu 22.04 LTS"
NAME="Ubuntu"
VERSION_ID="22.04"
VERSION="22.04 LTS (Jammy Jellyfish)"
VERSION_CODENAME=jammy
ID=ubuntu
ID_LIKE=debian
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
UBUNTU_CODENAME=jammy

This is how I created the container:

docker run -d --restart=unless-stopped \
  -p 80:80 -p 443:443 \
  -v /opt/rancher:/var/lib/rancher \
  --privileged \
--name=rancher_docker_server \
rancher/rancher:latest

After spinning up the docker container, the following logs were generated:

I think the issue is not related to the OS. The issue is the latest docker installation.
I just tried it on the Rocky Linux and I am getting the same error:

Hi,

Sorry for the confusion, its also not working on RHEL 7.9 as am getting below errors on RHEL 7.9

cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.9 (Maipo)

But getting the below error when it installs helm charts

Waiting for API to be available

I am very surprised, there is no information about the bugs or issues or support who can verify this and have any ETA to fix this. I am sure we are not only few people who are trying to install on Ubuntu 22.04 LTS and RHEL 7.9, there will be many more.

sandersbud4 · June 1, 2022, 11:38am

Can you double check your code?

Farhan_Ahmed · June 1, 2022, 12:54pm

Sorry, I didn’t get it. I am just creating docker from the latest image rancher/rancher:latest

wcoateRR · June 1, 2022, 2:41pm

What docker version are you running? I know that in CentOS 7 the Docker in the EPEL repo is too old for a lot of things and you’re often recommended to upgrade to Docker CE 19 or 20.

Farhan_Ahmed · June 2, 2022, 7:18am

It is 1.13 but am not fussy about RHEL/Centos as we are migrating to Ubuntu 22.04 LTS but rancher/rancher:latest doesnt work either on Ubuntu 22.04 LTS which is running docker 20

johnpugh · June 2, 2022, 11:20am

I don’t see Ubuntu 22.04 on the latest support matrix (20.04 is there), but have you tried running a “real” instance…meaning install RKE or k3s then using a helm install vs the test docker (unsupported) method? The errors seem to point to something blocking that port or otherwise preventing access to :6444.

wcoateRR · June 2, 2022, 4:19pm

Docker 1.13 definitely has problems, but I’ve seen Rancher work on CentOS 7 with Docker CE 19 several months ago. If you still have your CentOS 7 I’d try updating Docker (I had docker-ce & docker-ce-cli in my yum install command, but I had also needed to grab containerd.io from the Docker yum repo to my local repo as a dependency, it pulled the rest from main repos or EPEL).

Farhan_Ahmed · June 3, 2022, 9:12am

Hi,

Yes, I installed k3s on Ubuntu 22.04 and all working but when I installed rancher image, it is being failed and getting below error

2022/06/03 09:22:21 [INFO] Waiting for server to become available: Get “https://127.0.0.1:6444/version?timeout=15m0s”: dial tcp 127.0.0.1:6444: connect: connection refused

johnpugh · June 3, 2022, 12:20pm

How did you attempt to install rancher? I’m not sure what you mean by “rancher image”. This should be a resolvable name vs localhost so if you are using helm or the helm operator, share your values used.

Farhan_Ahmed · June 3, 2022, 11:17pm

Here is the command I ran

docker run -d --restart=unless-stopped --privileged -p 8080:80 -p 8443:443 rancher/rancher:latest

Below is the k3s.log within the rancher docker

On my side it works perfect on new install.

My Setup :

PRETTY_NAME="Ubuntu 22.04 LTS"
NAME="Ubuntu"
VERSION_ID="22.04"
VERSION="22.04 LTS (Jammy Jellyfish)"
VERSION_CODENAME=jammy
ID=ubuntu

BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
UBUNTU_CODENAME=jammy

I have modified my /etc/default/grub as follow :

GRUB_CMDLINE_LINUX="cgroup_memory=1 cgroup_enable=memory swapaccount=1 systemd.unified_cgroup_hierarchy=0"

And my sysctl.conf :

net.bridge.bridge-nf-call-iptables=1

Farhan_Ahmed · July 28, 2022, 9:31pm

@whitemike

After making the changes in /etc/default/grub, I confirm its start working. I am not sure why it is like that.

It is not mentioned anywhere in the documentation.

Thanks for the tip though.

Jagadeesh · August 17, 2022, 12:18pm

@whitemike
Thanks its works now after updating the Grub settings
